    Implementering av det biofila fenomen i utformningen av skolbyggnader2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Today, humanity is trying to develop in all areas of life, so that we can reach a cleaner, more modern, and more sustainable world. This study highlights the importance of architecture to improve areas of life. This report talks about a type of architectural design. It is called biophilic design which means to combine nature with buildings. This study is about biophilic design in school buildings.

    Method: To perform the survey, three different methods were chosen. The first method was a questionnaire sent to college students and high school students, the second method was interviews conducted with knowledgeable architects who have extensive experience in the subject of biophilic design and the last method was literature studies.

    Results: All data collected from the questionnaire, the interviews and literature studies are summarized as follows:Most college students and high school students think that when you are closer to nature it makes you feel better and that it would help improve the teaching process. Architects who were interviewed thought that biophilic design in school buildings has both advantages and disadvantages, but in general they support the idea of using and spreading the idea more in Sweden.

    Analysis: The analyzed data have shown that it is possible to implement biophilic design on the inside and outside of a school building in unusual ways. But many problems will arise, and one must have the will to continue to maintain these materials. It turned out that having these natural elements in school will contribute to a positive effect on the learning environment and the students themselves. For example, as a more creative, calm, and de-stressing environment. Having a green roof seems like an innovative idea but it requires a lot of maintenance.

    Discussion: This study focuses on how to implement biophilic design in a school building and what impact it has on the learning environment. The study addressed what is required to integrate the qualities of nature in the right way to maximize its effects. Studying biophilic design, nature and how it affects people and architecture and its impact on people has helped to lead to a clear result.

    Energy security and competition over energy resources in Iran and Caucasus region2017In: AIMS Energy, ISSN 2333-8326, E-ISSN 2333-8334, Vol. 5, no 2, p. 224-238Article in journal (Refereed)
    Abstract [en]

    Energy security as a dominant factor in international stability is of great importance for major economies. The global energy market with its current level of supply and demand relies on energy sources in the Middle East, Caucasus, Central Asia and Russia. After the Fukushima disaster nuclear powers in Europe view renewable energy sources as a serious alternative. Europe’s energy vulnerability has deteriorated due to the Russia-Ukraine conflict. However, renewable energy sources are not large enough to replace nuclear power completely. This trend will continue with climbing demand especially in the natural gas sector as clean energy. In this research, Caucasus and Iran are considered the main sources and routes for energy transmission to the global market, including Europe. Caucasus plays a key role in bridging Europe and Asia. Also, Iran is an alternative for energy transmission to Europe after lifted sanctions. As part of the European active supply diversification policy Iran has capacity to reduce Europe’s energy dependency on Russia. However, changes in US new administration America First Policy is harmful for the EUs energy security. Caucasus aims to catch a large share of the European energy market since the Baku-Tbilisi-Ceyhan pipeline has started operations and Iran is also trying to expand its market to become a sustainable source of energy for major consumers. Therefore, Iran and Caucasus are considered reliable energy suppliers for Europe. In this regard, we analyze the best motivation for changing the direction new suppliers’ energy policies towards Europe and suggest alternative solutions to compete with rival countries in order to enhance energy security.

    Barriers and Motivations to Energy Efficiency Technology Implementations: A Case Study in a Swedish Foundry Industry2021Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the pursuit of responding to climate change and reducing Greenhouse Gases (GHG) emissions caused by human activities, restrictions and regulations took place by international policymakers to limit the harmful effect on the environment. Thus, Energy-intensive industries are experiencing an unprecedented challenge due to more strict rules and limitations by governments in the EU and Sweden on unsustainable practices. 

    The purpose of the study is to highlight the barriers and benefits of investing in Energy Efficiency Technologies (EETs) such as Waste Heat Recovery (WHR) and Electric Energy Storage Systems (EESS) in a Swedish foundry firm. Further conduct a feasibility study of the selected technologies in the foundry energy system to understand to which extent improvements in Energy Efficiency (EE), cost reduction and GHG emissions take place. Further, contribute to the literature of Energy Management (EnM) by presenting a framework for decision-makers in energy-intensive industries to enable the implementation of EETs. 

    A single case study took place to generate and relate important theories in managerial practices. Semi-structured and structured interviews were conducted with experts involved in the foundry industry, EETs, and energy consultants. Moreover, documents were also provided to extract data. The qualitative data analysis was conducted using the framework analysis method while the quantitative analysis was performed using modeling through RETScreen software. 

    The results indicate that the main barriers to EETs are financial aspects, while environmental aspects were perceived as the most significant benefits. Furthermore, the feasibility study conducted proved a reduction of 4% in energy consumption, a reduction of 3% in annual GHG emissions, and a payback period of 5 years which was unfavorable for the investigated foundry. Further, the authors recommended an EnM framework based on EETs to ease their integration.

    Ett nytt perspektiv på plastavfallsflöden - från linjärt till cirkulärt: En kartläggning av plastavfallsflöden i GGVV-regionen2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of the study is to investigate opportunities for improvement in flows around region-based plastic waste management. To be able to answer the purpose of the study, the following two questions were formulated: 

    • What factors should be considered when introducing circular plastic waste streams? 
    • What is the responsibility of regional stakeholders in the introduction of circular plastic flows? 

    Method – The study is of an inductive approach in the form of a qualitative case study with an analysis unit based on two different analysis levels. In the study, the analysis unit is plastic waste management, which is broken down into the regional and actor level. To answer the presented questions, empirical data was collected in the form of interviews, questionnaires, and a document study. The Gioia method was used to transform data from interviews and surveys into themes and common factors with theoretical foundations. The method also makes it easier for the reader to follow the chain of evidence from data to analysis. 

    Findings – The results of the study show that today's plastic waste flows mainly follow a linear value flow and that the necessary flow must be changed towards a circular plastic waste flow. When introducing circular plastic waste streams, the following factors need to be considered for implementation to contribute to improvement: Design, Sorting, Transport and Economy. Furthermore, the study shows that the issue of liability is important for the possibility of claiming within the plastic waste flow and that today it is not clear who is responsible and when. This contributes to the fact that changes in plastic waste management must be clarified and that those responsible need to be named. The conclusions for the study and the result are that the problems surrounding plastic waste management need to be considered from a holistic perspective along the entire supply chain and that all actors involved must take their responsibility. 

    Implications – The study resulted in theoretical and practical contributions based on new knowledge. The theoretical contribution that the study has made is plastic waste management based on a regional approach where the theory today mainly deals with a circular economy based on company cases and national level. Additional theoretical contributions were made through common problem areas that were presented based on four factors, design, sorting, transport, and economy. These factors together with the theory of circular economy contributed to a theoretical contribution based on a developed model of the linear flow, to a more circular and sustainable plastic waste flow. The practical contribution is in the form of an increased understanding of the regional actors in the problem and who carries the responsibility in the various parts of the flow. This study can be used to get other regions to improve and develop their plastic waste flow at a regional level that benefits all actors. 

    Limitations – The current Covid-19 pandemic has affected the implementation of the study in the form of limited opportunities for visits to actors in the value chain. Another limitation is the geographical delimitation where the study only examines the flow based on a selected region, a study comprising several regions would have contributed to a more generalizable result. 

    Keywords – Plastic waste, Circular economy, Sustainable plastic use, Plastic waste flow, Circular plastic flow

    Assessment protocol and effects of two dynamic light patterns on human well-being and performance in a simulated and operational office environment2020In: Journal of Environmental Psychology, ISSN 0272-4944, E-ISSN 1522-9610, Vol. 69, article id 101409Article in journal (Refereed)
    Abstract [en]

    Sophisticated electric lighting solutions like tuneable white-light LED-systems, varying in light amount and/or colour temperature, can help to supplement or mimic daylight. Today's office environments are increasingly being equipped with dynamic lighting solutions even though it is yet unknown what a dynamic pattern looks like to optimally support human performance and well-being. In a pilot study, a dual-experimental methodology was employed to examine the effects of a dynamic lighting pattern. Two opposite dynamic electric light patterns were applied both in a controlled laboratory study as well as in a quasi-controlled field study. A momentary questionnaire concerning different aspects of well-being was repeated multiple times during the duration of the experiment, complemented by two performance tasks. The current results were inconclusive and inconsistent between the two study types, carefully pointing at the need to test dynamic light patterns in the field before implementing it in a real office environment.

    Barriers in the Initial Acceptance Phase to Life-Cycle-Assessment: A Case Study of a Swedish Manufacturer2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Sustainability and sustainable manufacturing has grown in importance in recent years, and more legislation and demands are put on organizations to show how their operations affect the environment. Life cycle assessment is a proactive and efficient sustainability tool to report a company’s effects on the environment. Nevertheless, life cycle assessments of products and organizations are complex and require significant resources. Therefore, the purpose of this study is to investigate what potential barriers can occur within the initial acceptance phase when implementing life cycle assessment in the manufacturing industry.

    Method: This research project is a single case study of a Swedish manufacturing company. The theory was deduced from literature where eight internal factors influencing the implementation of tools and systems created a foundation for data collection and analysis. Five semi-structured interviews and unstructured observations have been conducted to collect empirical data.

    Findings: Nine second-order themes of factors influencing the project as barriers have been identified that construct the three aggregate dimensions ̈Lack of management support ̈, ̈Lack of resources ̈, and ̈Lack of interdepartmental coordination ̈. From the empirical findings, it is also suggested that the three aggregate dimensions are interrelated. The interrelationships are later used to find three change suggestions to mitigate the barriers by using the relationships between the dimensions and targeting as many barriers as possible. Namely, ̈educate top management ̈, ̈enhance the education of project participants ̈, and ̈spend more time on project planning ̈.

    Implications: This study provides a deeper and more detailed understanding of different barriers within the initial acceptance phase of a project. It also gives further insights into various interrelationships between barriers and how one dimension can influence the other in both positive and negative ways. Furthermore, this study's findings can guide managers and practitioners in preparing for a project aiming to implement a tool or a system.

    Limitations: As in all interpretative research, the interpretations of the empirical data are based on subjective thoughts influenced by the researcher’s positionality, the relationships with the participants, and preconceived perceptions. Furthermore, this research project is a single case study, and the results apply to this case. The findings cannot be statistically generalizable, meaning that the theories and themes created in this report should not be seen as absolute truths but instead as suggestive theories within the field.

    Influencing Factors in the Implementation of Green Management Practices: A Qualitative Study regarding Swedish SMEs in Logistics2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The subject of green management is today relatively unexplored in existing literature, especially regarding SMEs in logistics. To bridge this gap this study aims to find what factors influence the implementation of green management for SMEs in logistics. Furthermore, this study aims to address the influential weight of these factors to create an even greater understanding within the topic.

    The chosen research method of this paper is qualitative, and the empirical data is collected through semi-structured interviews with Swedish logistic companies who have acquired the environmental management system ISO 14001. Furthermore, the research approach of this study is deductive.

    When implementing green management, this paper has found 4 factors that influence a company in various ways. What also has been found is what factors that have more influential weight and are essential to make such implementation effective.

    The study provides both theoretical and practical implications. Theoretically it fills a gap current literature and further explains SMEs in logistics use of green management. Practically companies can draw from this study to see if they work effectively with green management or better prepare for a transition. The researchers of this study suggest that the factors of influence that are presented in the empirical findings should be tested in a quantitative study with a larger sample size to better measure the effect of each one in a practical context.

    Miljöledningssystem: En förberedande fallstudie för ISO 14001 certifiering2021Independent thesis Basic level (university diploma), 180 HE creditsStudent thesis
    Abstract [en]

    Climate change has become a subject that is frequently reported in the media. There is an increased awareness and interest among consumers about environmental issues. Therefore, companies try to adapt their business to work in a more sustainable way. The ISO 14001 standard is a helpful tool to structure an environmental management system. It is an established framework on how companies can continuously improve their business to minimize the climate footprint. 

     

    This report is based on a company that aims to become certified according to ISO 14001. The company is ISO 9001 certified, and several areas are addressed in both standards, which is beneficial for the implementation of their environmental management system according to ISO 14001. The goal off this study is to prepare the company by identifying gaps in their current environmental management system compared to the ISO 14001 requirements. 

     

    The GAP-analysis determined the significance of the gap, by dividing gaps in three categories: Minor, Major and Critical. The result showed that almost half of the requirements is considered as minor gaps, which means that the company with minor actions can meet the requirements. The other half is categorized as major and critical gaps, which will need significant actions and resources to meet the requirements. The result from the GAP-analysis shows that the company, due to the similarities between ISO 14001 and ISO 9001, have a good potential to meet the requirements. To start their certification process, the study presents 18 actions based on the result from the gap-analysis for the company to consider.

     

    The purpose of ISO 14001 is not only for a company to get a certificate, but also to continuously improve their environmental management system. Therefore, the company must develop and increase their knowledge of the standard to fully understand it and there by fulfill its purpose.

    Green Transitions in Heavy Truck Transports: An explorative study on buyer-supplier challenges and enablers for green transition in the Swedish truck transportation industry2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background 

    Global warming caused by greenhouse gas emissions necessitates a decrease in carbon emission caused by the truck transport industry. To combat the threat of global warming, goals are being set up on a global, national and corporate level. These goals are putting pressure on logistics service providers to decrease the emissions within the truck transport industry. Implementation of green practices is found to be especially challenging within heavy truck transport due to weight and distance of the transport characteristics. In order to achieve emission reductions, logistics service providers are dependent on the alignment with their transport buyers, known as shippers to implement green logistics practices.

    Purpose

    The purpose of this study is to identify challenges and enablers for sustainable green transitions within heavy truck transports among shippers and logistics service providers. The study formulates two research question to help achieve the purpose, these questions are focused on challenges and enablers among both shippers and logistics service providers. 

    Method

    The study employs an explorative research approach in a multiple case study setting. Three configurations of shipper-LSP relationships are studied and analyzed through thematic analysis, the researchers also conducted a cross-case analysis to compare and identify similarities and differences between the cases in order to draw conclusions. 

    Conclusion

    A green transition within the heavy truck transport sector face numerous challenges. The challenges include a high dependency on vehicle development, lacking infrastructure, alignment issues between shippers and logistics service providers and trade off dilemmas. In order to overcome the issues findings, suggest that shippers and LSPs should focus on creating shared goals in order to facilitate implementation of green logistics practices and mitigate the challenges.

    Kartläggning av företagens användning av de 3R:en2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: To map the companies’ use of the specific 3R’s (reuse, remanufacture and recycle) as well as gain an understanding of  the cooperation opportunities between manufacturing organizations and companies that work with the 3R’s:

     

       1) What factors play a role in the companies’ use of the specific 3R’s?

       2) Which cooperation opportunities do the companies’ see from a sustainability perspective?

     

    Method: The study was based on a multiple case design which consisted interviews. The interviews were based on companies that manufacture and develop electronic and electrical equipment (EEE) and companies who are engaged in taking care of the used EEE. The study also contained different literature studies in sustainability, which further lead to the creation of the theoretical framework in cooperation with the purpose of the study. Between the theoretical framework and the study's empiricism an analysis could be carried out, which also contributed to the results of the study.

     

    Result: The study has resulted in the identification of several different factors for the specific 3R’s, together with cooperation opportunities between manufacturing organizations of EEE and companies that take care of the consumed EEE based on the specific 3R’s. Where economic sustainability, i.e. profit maximization has been the factor that has permeated a large part of the results, together with some influence from environmental considerations.

     

    Implications: The study does not establish a new theory but bases itself on existing theories that have been tested in reality through interviews. During this study, it has been clear that the economic factors are one of the most important elements that determine how companies choose to work. Profit maximization is such a big factor that it also affects and outweighs environmental considerations when placed against each other. Environmental considerations are usually less considered than profit maximization but should weigh at least as much as profit maximization during the decision-making process.

     

    Limitations:

    • The study is based only on companies located in Sweden.

    • This study does not address/treat social sustainability or social considerations.

    • The study is based on producer companies that manufacture and develop electronic and electrical products as well as companies that work with reuse, remanufacture and recycling of electronic and electrical products.

    Moving toward a circular economy in manufacturing organizations: the role of circular stakeholder engagement practices2023In: The International Journal of Logistics Management, ISSN 0957-4093, Vol. 34, no 3, p. 674-698Article in journal (Refereed)
    Abstract [en]

    Purpose

    The circular economy (CE) approach has been acknowledged as key for manufacturing organizations wishing to overcome sustainability challenges. However, the transition has been slow. Stakeholder engagement is a driver of the transition, but there is limited knowledge on stakeholder engagement practices in a CE context. The purpose of this paper is thus to explore with whom, on what and how organizations engage with stakeholders to implement CE as part of sustainability efforts.

    Design/methodology/approach

    This study is situated at the intersection of CE, stakeholder theory and supply chain literature. A case study with three Swedish manufacturing organizations was conducted to explore stakeholder engagement practices that facilitate the implementation of CE in organizational practice and the supply chain, considering conceptual differences between stakeholder engagement for sustainability and CE.

    Findings

    This study provides empirical evidence on how manufacturing organizations engage stakeholders to implement CE as part of organizations' sustainability efforts. The study highlights that manufacturing organizations have to move not only from linear to circular resource flows, but also from linear to circular stakeholder engagement. Such engagement can be achieved by extending with whom, expanding on what and leveling up how stakeholders are engaged.

    Originality/value

    This study provides an enhanced conceptual understanding of stakeholder engagement in the CE context and discusses differences regarding stakeholder engagement based on linear thinking. The study emphasizes the role of circular stakeholder engagement practices for the transition toward CE in manufacturing organizations.

    Implementation Of Eco-Design In Product Development: Knowledge management for effective eco-design implementation2021Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Background: The accumulating concern for environmental change has increased the need for companies to take a closer consideration to the negative impact of their operations. One effective approach to mitigate the impact is to, from the very first stages when a product is developed, analyse the environmental impact of the product’s entire lifecycle from the raw materials extruded from the ground to the disposal of the product. This type of practice is often referred to as eco-design. Unfortunately, the rate of companies implementing these practices are progressing slowly and a truly sustainable society is yet not in reach.

    Purpose: This study aims to investigate some of the most commonly cited obstacles in previous research. These problems can be concluded as the lack of specialized competencies, regarding the environmental impact of products in design teams. The reason this is problematic is that the practice of eco-design often requires a lot of information to be interpreted by a person with knowledge in the field. Companies have attempts to solve this issue by hiring eco-design specialists, however this often leads to difficulties in communication and disagreements with product developers. Therefore, this relationship between different stakeholders has been the second focus of the thesis. To find solutions to these problems the topic will be investigated from a knowledge management perspective.

    Method: To begin with, background data was reviewed to give a firm understanding of the topic and to create the basis of the theoretical framework. Later a multiple case study of two companies were performed and empirical data was gathered mainly from interviews. The empirical findings were analysed and compared to the theoretical framework in order to answer the research question.

    Conclusion: The results show that implementing eco-design in a company's product development can be hard in the implementation phase but when the practices are established the flow of information receives less problems. Furthermore, the hiring of professional eco-designers can be a good choice although they need to be implemented directly into the design teams.

    Analysing human factors and non-technical skills in offshore drilling operations using FRAM (functional resonance analysis method)2021In: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 23, no 3, p. 553-566Article in journal (Refereed)
    Abstract [en]

    Workplaces in the oil and gas (O&G) industry have evolved to become part of the modern complex sociotechnical system that characterises onshore and offshore facilities today. The intense interactions between workers, systems, equipment and processes have made companies in this sector more productive. However, significant and complex risks have also emerged. Managing them requires a methodology capable of understanding and recognising how this entire sociotechnical system works. This research uses the FRAM to model the activities performed by drillers, from the perspective of their workplace, inside the drilling unit of an offshore oil rig—a complex sociotechnical system. The interviews, on-board observations and data gathering performed as part of this study provided information that was used to build a FRAM model capable of representing the real work done by drillers inside the doghouses on offshore oil rigs. Through this model, the variability of human behaviour could be analysed in the context of the different situations that may happen, enabling researchers to understand the specific demands of the work and the correlation between WAI and WAD that naturally emerges. This FRAM-based analysis acknowledges that human factors and non-technical skills are responsible for the productive and safe execution of the work in both normal and critical operations situations, and identifies the impact of this variability—positive or negative—in the execution of daily tasks. It shows that workers’ varied responses can properly deal with complex system demands both in normal situations and in emergencies.

    Decentralized environmental regulations and plant-level productivity2019In: Business Strategy and the Environment, ISSN 0964-4733, E-ISSN 1099-0836, Vol. 28, no 6, p. 998-1011Article in journal (Refereed)
    Abstract [en]

    Using the framework provided by the Porter hypothesis, we study the impact of environmental regulations and enforcement policies on plant-level green total factor productivity (TFP) growth and its components related to efficiency change and technical change. The detailed microdata we use are from Sweden and for the pulp and paper industry. This industry is the source of significant amounts of water and air pollution and is one of the most heavily environmentally regulated manufacturing industries. Sweden has a unique decentralized regulatory structure where the manufacturing plants have to comply with plant-specific regulatory standards stipulated at the national level, as well as decentralized local supervision and enforcement. Our empirical results point to beneficial impacts of the environmental policies on plants' green TFP growth and sustainable production practices. We also find that political economy considerations are important, as the presence of the Green Party and aspects like plant size (with corresponding local and regional economic effects) matter in enforcement of the standards.

    The Relationship of Weather with Electricity Prices: A Case Study of Albania2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Electricity markets may become more sensitive to weather conditions because of higher penetration of renewable energy sources and climatic changes. Albania is 100% reliant on hydropower for its domestic energy generation, making this country compelling to investigate as it is highly sensitive to changing weather conditions. We use an ARMA-GARCH model to investigate whether weather and economic factors had a relationship with monthly hydroelectricity prices in the Albanian Energy Market in the period 2013-2018. We find that electricity price is affected by variations in weather and is not utterly robust to extreme hydrological changes. Generally, our dependent variable appears to be particularly influenced by air pressure followed by temperature and rainfall. We also perceive that there is a relationship between economic factors and hydroelectricity prices, where residual supply appears to have a significant negative relationship with our dependent variable. However, we were originally anticipating a higher dependency of electricity prices on weather conditions, due to the inflated hydro-power reliance for electricity production in the Albanian Energy Market. This effect is offset by several factors, where the state monopolized behaviour of the energy sector occupies a predominant influence on our results.

    Costs of air pollutants from shipping: a meta-regression analysis2020In: Transport reviews, ISSN 0144-1647, E-ISSN 1464-5327, Vol. 40, no 4, p. 411-428Article in journal (Refereed)
    Abstract [en]

    This study estimated the external cost of air pollution from shipping by means of a meta-regression analysis, which has not been made before. Three pollutants, which were included in most of the primary studies, were considered: nitrogen oxides (NOx), sulphur dioxides (SO2) and particulate matters with a diameter of max 2.5 micrometres (PM2.5). All primary studies included damages of health and a majority added impacts on agriculture and estimated the cost of air pollutants by transferring cost estimates from studies on costs of air emissions from transports in Europe. Different regression models and estimators were used and robust results were found of statistically significant emission elasticities of below one, i.e. total external costs increase by less than 1% when emissions increase by 1%. There was a small variation between the pollutants, with the highest elasticity for PM2.5 and lowest for NOx. Calculations of the marginal external cost of the pollutants showed the same pattern, with this cost being approximately six times higher for PM2.5 than for the other pollutants. Common to all pollutants was that the marginal external cost decreases when emission increases. Another robust result was a significant increase in the cost of studies published in journals compared with other publication outlets. These findings point out some caution when transferring constant external unit cost of air pollutant from shipping, which is much applied in the literature, and the cost functions estimated in this study could thus provide a complementary transfer mechanism.

    Kartläggning av en svensk flygplats miljöledningssystem2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report was written as a part of the bachelor program, Industrial Organization and Economics, focusing on logistics and management, at the School of Engineering in Jonkoping.  The report was written on behalf of Skövde Airport Company, which is a municipally owned airport company.  Skövde Airport is located within a few miles outside the city of Skövde, Sweden.

     

    The airport serves mainly cargo planes but occasionally serves smaller passenger flights as well.  Today, companies like Kinnarps AB and Volvo Powertrain, are their biggest customers.  The airport also includes a fire station service and offices for these larger customers.

     

    The purpose of this study is to provide an assessment of Skövde Airport’s surrounding issues. Our goal is to provide suggestions as to what the airport can implement as well as continue working on to improve the airport environment.  Therefore the study also examines other options in terms of ways to prepare to work with the environment; these systems are called “Environment Management Systems (EMS).”  Consequently, the study has taken parts of these EMS: s to identify and describe what parts are most critical from an environmental perspective.

     

    The report includes a critical examination of the airport and explanation on how the airport works with the environment. The investigation portion of this thesis presents our mapping of the Skövde Airport Company’s current EMS.  The analysis describes everyday business activities and how these everyday activities are impacting the environment. Finally, the report concludes our reflection of the outcome of implementing these suggestions we have presented.

     

    During this process the study found a number of deficiencies at Skövde airport. Today Skövde airport is missing vital information and documentation on its activities and the EMS. The airport currently holds a diploma for their EMS, but according to this study it’s missing vital information and documentation. Skövde airport is a complex organization to describe and even today there are many different opinions and views about its function and business.

     

    The result of this study is therefore based on a document study. During the project time information had been collected from documentation, visits at the airport, interviews and communication with employees.  The result is presented in the final chapter in the form of proposals and recommendations to Skövde Airport.

    Granskning av hur ett miljöledningssystem uppfyller kraven i SS-EN ISO 14001:20042007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose with this report is to make a contribution to Bodycote heat treatments workshop in Värnamo, how to introduce, establish and constantly improve its environmental system. The rapport will help Bodycote with there certifying in ISO 14001: s demand standard. Organizations who continuously work with environmental issues have a lot to gain. Two things an active environmental development process will convey are, building of thrust within the circle of customers, and great financial savings. An increasingly numbers of organizations realize the importance to introduce a functioning environmental system into their activity. The investment in a functional environmental system normally has a pay back time in just a few years.

    A perusal was carried out of the current documents and routines in the environmental system of the workshop. This perusal has later been presented through comments and by proposals to improvements. The result of the perusal showed that there are certain areas of the environmental system that not are properly fulfilled by the standard demands. For example the guaranteed concern for the important environmental aspects, when the system is established, introduced and supported. The problem is rooted in the lack of information documented by the organization. There shall be a list documented over the most important environmental aspects.

    Other important demands that the standard proclaim, is the comprehensive and the detailed environmental goals. These goals are not established, introduced or supported. Each environmental goal shall have an achievement plan, plans that are yet not active or documented. According to the demands in standard, the workshop shall guarantee that the measurement of environmental performance is performed in a proper way. A routine on these demands was not found during the perusal.

    The conclusion of the perusal is that the most of the criteria’s in the standard is fulfilled by Värnamo workshop. To succeed with the certifying, the workshop shall especially look at demands concerning the important environmental aspects, the comprehensive and the detailed environmental goals. These demands are vital through out the whole environmental system. However, the other demands that are not fulfilled are also important.

    Adoption of Really New Products: Retro Appearance and the Bandwagon Effect2014In: Marketing theory challenges in emerging markets / [ed] Maja Szymura-Tyc, 2014, p. 23-Conference paper (Refereed)
    Abstract [en]

    The literature has paid far too little attention to the potential impact of retro appearance and bandwagon effect on the adoption of really new products. By integrating the retro appearance and bandwagon perspectives, we aim to contribute to the understanding of adoption of really new products. We purport that retro appearance and peer effect – familiar product appearances and observing peer usage – may attenuate the negative prejudgments towards really new products associated with perceived risks and facilitate adoption.

    Crude oil production prediction based on an intelligent hybrid modelling structure generated by using the clustering algorithm in big data2023In: Geoenergy Science and Engineering, ISSN 2949-8910, Vol. 225, article id 211703Article in journal (Refereed)
    Abstract [en]

    Since the behavior of a complex dynamic system for a large oil field in Iraq is significantly influenced by many nonlinearities, its dependent parameters exhibit non-stationary with a very high delay time. Developing white-box modelling approaches for such dynamic oil well production cannot handle these large data sets with all dependent dimensions and their non-linear effects. Therefore, this study adopts the hybrid model that combines white-box and black-box to address such problems because the model outputs require various variable types to achieve optimal fitness to measured values. The hybrid model structure needs to evolve with changes in the physical parameters (white-box part) and Neural Networks' Weights (black-box part). The model structure of the proposed hybrid network relied on converting fuzzy rules in a Takagi–Sugeno–Kang Fuzzy System (TSK-FS) into a multilayer perceptron network (MLP). The hybrid parameters are formulated concerning six-dimensional dependent variables to describe them in matrix form or layer and by which can quantify total model outputs. After mapping categorical variables to tuples of MLP, the Gauss-Newton regression (GNR) provides an optimal update of the hybrid parameters to get the best fitting of the model outputs with the target of the dataset. The clustering technique and GNR promote predictive performance due to reducing uncertainties in the hybrid parameters. Due to time being the most effective of the independent variables for predicting oil production, datasets are classified into different clusters based on time. The actual field dataset for training and validation is collected from Zubair Oil Field (9 oil wells), which is implemented to build the proposed model. The results of the hybrid model indicate that the development of the proposed structure has achieved the high capability to represent such big data which is the most imperative feature of the proposed model. Furthermore, obtained results show its accuracy far outpacing competitors and achieving a significant improvement in predictive performance.

    Method: The qualitative methods that have been utilized for this thesis are multiple document assessments as well as literature studies and calculations. The literature analysis was applied to answer all inquiries. The document assessments have been used to answer the first and second question. The calculations were used to answer the first and the third question. 

    Results: The study shows that the true effect capacity of the battery, discharge time, amount of life cycles per year inclusive to the cost of electricity becomes a significant factor for the expenses in the administration. The study also shows that the usage of battery storage is currently unprofitable based on modern-day solar cell strategy. 

    Analysis: The analysis uses a qualitative approach. Document analysis and the calculations are presented in a form of charts, diagrams, and graphs to facilitate for the reader. The literature inquiry has been an excellent way to navigate through the area with the information available. 

    Discussion: The result discussion emphasizes both pros and cons with the battery storage for a total cost of 2 600 000 SEK with the help of document analysis results as well as previous literature concerning battery storage and LCOS. Expected price reductions in battery costs and increased electricity prices will be decisive factors for a future investment. Methods that have been carefully selected offer an insight into the usage of the battery.

    Application of analytical hierarchy process for selecting an interior window blind2017In: Architectural Engineering and Design Management, ISSN 1745-2007, E-ISSN 1752-7589, Vol. 13, no 4, p. 308-324Article in journal (Refereed)
    Abstract [en]

    Window blinds have a substantial role in shaping the energy consumption and improving thermal comfort and visual comfort. However, difficulties in selecting a window blind remain, due to existence of potential conflicts between visual, thermal, energy and life cycle cost. To overcome this problem, this study evaluates the performance of interior blinds, including venetian with slat of 0° and 45°, roller and double-pleated blinds with respect to visual, thermal, energy and life cycle cost. Later, the Analytical hierarchy process (AHP) is used for selecting the best blind based on trade-off among the visual, thermal, energy and life cycle cost. In using AHP, visual comfort is determined as most important objective with a weight of 52%. The results show that venetian blind (VB) with slat of 0° drawn 100% is the trade-off blind. Accomplishing the sensitivity analysis on blinds’ global weight shows that VB with slat of 0° drawn 100% remains the trade-off blind until the weight of energy and life cycle cost is below 37% and 57%, respectively, and the weight of visual comfort is above 4%. However, changing thermal comfort weight has no impact on ranking of the blinds. This study shows the capability of AHP in managing the conflicts.

    Parameter setting on catalytic controller: Using Design of Experiments and Scanning Electron Microscope Analysis2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis work has been conducted in the Handheld Laboratory at Husqvarna AB with the purpose of finding the parameters responsible for the performance of the catalytic converters used in the test rig. The catalytic converters are used in the test rig during the long term testing of the chain saws to reduce the hydrocarbon content from the exhaust before it enters into the environment.  

    To perform this research two approaches were carried out. One with Design of Experiment (DOE) and another using Scanning Electron Microscope (SEM) analysis. In Design of Experiments parameters that are suspected to be influencing the performance of the catalytic converter were refined. Using these parameters a test plan is made with the help of statistical analysis application Minitab and the tests were carried out in the test rig. Using SEM the effects of aging and its effect on microstructure and chemical composition on the catalyst surface was analyzed.

    The results from the DoE shows that the exhaust flow, collector diameter and distance to the muffler are responsible for the collection of exhaust. Distance to the muffler and collector length are the factors affecting the conversion of the exhaust. In addition to that exhaust flow is also responsible for the duration of heating coil running time.       

    The results from the SEM analysis shows that the operating temperature is high due to which there is thermal degradation of catalyst and there is also deactivation due to fouling. Another finding is that the flow on to the catalyst is not uniformly distributed

    Developing a Framework for the Environmentally Sustainable Selection of Materials and Manufacturing Processes: A Case Study at a Luminaire Company2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to investigate what environmental factors to consider when selecting materials and manufacturing processes and designing a proposed framework to aid the material and manufacturing process selection. To facilitate the accomplishment of the purpose, two research questions were formulated. 

    A literature review was conducted to provide a theoretical foundation for the thesis and facilitate the ability to address the research questions. Furthermore, to address the research questions concerning which environmental factors to consider and how a framework can be developed for selecting materials and manufacturing processes based on environmental factors, structured literature studies were conducted. The selected topics of these studies included manufacturing process selection, material selection, and sustainable development goals. To aid in the design of the framework, a Case Study and Interviews were conducted at a local luminaire company. These efforts were undertaken to provide insights into the practical considerations involved in implementing an environmentally conscious framework for material and manufacturing process selection. 

    The study involved a comparison of two distinct approaches, namely, Life Cycle Assessment and Multi-Criteria Decision-Making, to determine their efficiency in achieving the research purpose. This resulted in the inclusion of Life Cycle Assessment in the proposed framework. Additionally, the Interviews conducted were analyzed to gain useful insights that could inform the development of the framework. 

    A framework was designed, using the analysis of the Interviews and the identified literature. The environmental factors considered in the framework were the Impact Categories. Moreover, the framework was then validated in a Case Study. 

    The Discussion and Conclusion chapter include the Methods, Results & Analysis, Framework Design, Framework Contribution to Sustainable Development Goals, the Research Questions, and the Ethical Aspects needed to be considered in this study. It is concluded that Impact Categories are reasonable to consider as environmental factors and that the proposed framework works in a real-life case.

    Energy comparison of wireless data transfer in an energy critical driven system: Digitizing analog meters for the world of IoT - An energy study in a concrete environment2022Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Digitizing analog meters into the IoT where meters can be read remotely is a solution which is both environmentally and economically beneficial. This study investigate show energy critical systems can gain a longer lifespan by optimizing their energy consumption. The purpose of this study is to evaluate the energy consumption of energy critical systems with different wireless data transfer protocols. This is conducted with experiments and observations.The data was collected by setting up two testbeds where the wireless transmission interfaces WiFi and BLE were used to send data between two microcomputers. These testbeds measured the energy consumption when altering with the variables of the two transmission protocols.The result shows that the internal protocols of WiFi were greatly affected by the changes made in the variables compared to BLE during the experiments. The results also show that when calibrating the different variables, the energy consumption is reduced by up around 52%. Furthermore, the result indicates that there is energy to saveif you optimize transmission power to a specific environment.In this study, BLE has little to no change to the energy consumption when changing the different variables. When investigating the internal protocols of WiFi, they are greatly affected by the different variables being changed. A lower transmission power can be more energy efficient but at the cost of shorter range and eventually a higher packet loss.

    Miljöfokuserade start-ups: En empirisk undersökning om nystartade företags förutsättningar att minska sin miljöpåverkan2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study is to examine what possibilities start-up companies have to work in an environmentally sustainable way, and what barriers they face in that context. The study moreover presents enabling factors which help start-ups realize opportunities and overcome barriers. To fulfill the purpose, it has been divided into two research questions, which follows:

    What opportunities and barriers do start-up companies, who want to work in an environmentally sustainable way, face?

    Which enablers can an environmentally sustainable start-up companies make use of to seize opportunities and lower barriers?

    Method: To fulfill the purpose a single case study was conducted. Empirical data was collected from a case company by semi structured interviews based on the theoretical framework. The selected case company is a start up with high focus on sustainability and the environment. A business incubator was also interviewed using semi structured questions to complement the empirical data collected from the case company. This empirical data was then analyzed against the theoretical framework which then lead to the study’s results.

    Findings: The study identified three major opportunities which help start-ups in an environmentally sustainable way: an increase in demand for environmentally products; tightened environmental regulations, and increased credibility from stakeholders. Moreover, four major barriers to environmental sustainability in start-ups were found: a low degree of market maturity; lack of financial resources and human capital; competition from established firms; and difficulties in attracting investors. In terms of enablers, the following factors were deemed instrumental in seizing opportunities and overcoming barriers: start-ups’ organizational flexibility, which allows them to rather quickly master necessary organizational change processes towards environmental sustainability; usage of environmental principles; social capital; and incubators as well as other external guidance.

    Implications: Presented opportunities, barriers and enablers are based on previous studies, the result of this study increase the understanding about how start-ups can work more environmentally focused. The empirical findings about incubators role in helping start-ups becoming more environmentally focused is an unexplored area and needs more attention in the literature. Societies can benefit from this increased understanding since it can lead to a decreased environmental impact, both on a local level by consuming less resources and a global level by slowing down the climate threat.

    Limitations: By including only one case company and one incubator combined with the qualitative research approach, the study covers a wide but shallow area. By including multiple case companies and incubators the study would have reached a higher level of generalization. Documents could have been studied in order to reach a more quantitative result with could have increased the credibility of the study.

    Comprehensive Environmental Assessment Index of Ecological Footprint2023In: Environmental Management, ISSN 0364-152X, E-ISSN 1432-1009, Vol. 71, p. 465-482Article in journal (Refereed)
    Abstract [en]

    This paper aims to contribute to the growing body of research literature on assessing environmental efficiency by introducing a new key performance indicator (KPIs) in more complete and dependable aspects of ecological footprint indices. For this purpose, the DEA model considering three inputs (energy consumption, labor force, and capital stock), one desirable output (GDP), and different undesirable outputs (CO2 emissions, ecological footprint indicators) are applied to 27 OECD countries from 2000 to 2017. According to the results, Norway, Luxemburg, and United Kingdom are the most environmentally efficient countries in terms of environmental efficiency and ecological footprint efficiency. On the other hand, the lowest environmental and ecological footprint efficiencies were in countries like Lithuania, Slovak, Czech, Estonia, and the USA. In addition, these nations fare poorly regarding their carbon footprint and farmland efficiency. In further detail, Lithuania, South Korea, Portugal, and Spain have a critical status in fishing ground efficiency, while the forest area efficiency is very acute in Estonia, Latvia, Lithuania, and Czech.

    Global change effects on plant communities are magnified by time and the number of global change factors imposed2019In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 116, no 36, p. 17867-17873Article in journal (Refereed)
    Abstract [en]

    Accurate prediction of community responses to global change drivers (GCDs) is critical given the effects of biodiversity on ecosystem services. There is consensus that human activities are driving species extinctions at the global scale, but debate remains over whether GCDs are systematically altering local communities worldwide. Across 105 experiments that included over 400 experimental manipulations, we found evidence for a lagged response of herbaceous plant communities to GCDs caused by shifts in the identities and relative abundances of species, often without a corresponding difference in species richness. These results provide evidence that community responses are pervasive across a wide variety of GCDs on long-term temporal scales and that these responses increase in strength when multiple GCDs are simultaneously imposed.Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100 experiments that manipulated factors linked to GCDs, we show that herbaceous plant community responses depend on experimental manipulation length and number of factors manipulated. We found that plant communities are fairly resistant to experimentally manipulated GCDs in the short term (<10 y). In contrast, long-term (≥10 y) experiments show increasing community divergence of treatments from control conditions. Surprisingly, these community responses occurred with similar frequency across the GCD types manipulated in our database. However, community responses were more common when 3 or more GCDs were simultaneously manipulated, suggesting the emergence of additive or synergistic effects of multiple drivers, particularly over long time periods. In half of the cases, GCD manipulations caused a difference in community composition without a corresponding species richness difference, indicating that species reordering or replacement is an important mechanism of community responses to GCDs and should be given greater consideration when examining consequences of GCDs for the biodiversity–ecosystem function relationship. Human activities are currently driving unparalleled global changes worldwide. Our analyses provide the most comprehensive evidence to date that these human activities may have widespread impacts on plant community composition globally, which will increase in frequency over time and be greater in areas where communities face multiple GCDs simultaneously.

    Optimization of PCB Heater Heating Profile for Power-Efficient Humidity Management in Electronics Enclosures2011Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this master thesis, automated optimization simulation laboratory is developed and implemented for power-efficient humidity management. A concept of local heating as a humidity management measure in electronics enclosure in severe environmental conditions has been evaluated. Environmental conditions included an instant change of the temperature from 0o C to 24o C and relative humidity 30% to 95%. Evaluation process has been developed as an optimization problem solved by integrating CFD modeling and excel data sheet calculations into the automation simulation workflow environment. Heating profile vector has been defined as design variable and optimized objective was defined as the difference between surface temperature of heated IC package and local dew point temperature. The task included interfacing between floTHERM and OPTIMUS tools, sensitivity analysis and CFD model simplification in order to obtain time efficient simulation models subsequently used in optimization process. Ultimate goal in the optimization was to obtain a power efficient heating profile for the local heater that keeps local relative humidity at low level thereby minimizing moisture induced electronic reliability problems.

    From energy consumers to prosumers-how do policies influence the transition?2021In: Electrification: Accelerating the Energy Transition / [ed] P. Aalto, Elsevier , 2021, p. 197-215Chapter in book (Other academic)
    Abstract [en]

    Active producer-consumers (prosumers) still number relatively few in most countries, excluding frontrunner countries such as Germany and the USA, where small-scale solar power generation by property-owners has made strong inroads. To unleash their potential for a transition to a more climate-neutral electric energy system, identifying the potential enablers and constraints for the proliferation of prosumption is crucial. Policy mixes have been identified as important enablers for industry transitions. We report a case comparing the similarities and differences among prosumer-related policies in five European countries: Finland, France, Germany, Italy, and Switzerland. We also introduce an empirical case study on how policies in these countries may influence consumer attitudes in favor of small-scale renewable energy production. We conclude the chapter by discussing the best practices and the mix of more precise policy instruments deployable for involving citizens in order to accelerate the electrification of the energy system.

    Policy influence on consumers' evolution into prosumers-empirical findings from an exploratory survey in Europe2018In: Sustainability, E-ISSN 2071-1050, Vol. 10, no 1, article id 186Article in journal (Refereed)
    Abstract [en]

    The energy sector is in transition to a flexible and sustainable energy system based on renewable energy sources. This complex transition is affecting multiple levels in the sociotechnical system. One driver of the transition is climate change that enforces the policy push from the macro level to change the way energy is produced, delivered, and used. As part of the energy system evolution, the role of the end user in the energy sector is undergoing profound changes, and consumers are increasingly being empowered to participate actively in the production and use of energy. This article investigates how policies might affect consumers' interests in becoming prosumers of energy. We explore consumers' attitudes toward using renewable energy technologies (RET) by means of an empirical consumer survey that was conducted in five European countries. The partial least squares structural equation modeling (PLS-SEM) method was utilized to analyze the survey results. Our findings suggest that both economic and non-economic policies affect consumer attitudes toward using renewable energy technologies. We conclude that policies have different effects on consumers and prosumers, who have already made the decision to adopt renewable energy solutions. Based on the findings, we propose a set of policy and managerial implications.

    Exploring the microfoundations of end-user interests toward co-creating renewable energy technology innovations2019In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 229, p. 203-212Article in journal (Refereed)
    Abstract [en]

    Energy market transition, which is enabled by new affordable energy technologies and digitalization, opens novel opportunities for developing innovative energy solutions. These new technologies facilitate energy consumers to become local energy prosumers i.e. consumers and producers of energy using renewable energy sources. Hence, a central question for innovating new solutions emerges: how energy consumers and prosumers would engage in co-creating value and novel solutions with industry players? This article explores the microfoundations of energy consumers' and prosumers’ interest to participate in co-creation activities with energy industry actors. Using survey data from five European countries and by applying variance-based structural equation modeling, we find that rewards and personal characteristics influence the interest to engage in co-creation activities. Specifically, the microfoundations of the interest are built upon the need for improvements, the intrinsic rewards, and the personal adopter characteristics. Additionally, we find differing microfoundations of interest for energy consumers and prosumers. We further discuss managerial and theoretical implications of our findings and highlight avenues for future research.

    An overview of the problems posed by plastic products and the role of extended producer responsibility in Europe2019In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 214, p. 550-558Article in journal (Refereed)
    Abstract [en]

    Plastic products are easy and convenient for our everyday use, but their negative impacts on human health and the environment cannot be overlooked. The negative impacts and effects of plastic waste are now widely known and have been subject of much recent media coverage, both in Europe and on a global level. Faced with increasing amounts of plastic waste, the European Union as a whole and many European governments in particular, are currently revising the policy options available to cope with the problem. One of the tools which may be deployed with a view to reducing the pressures posed by plastic waste, is the Extended Producer Responsibility principle. It is considered to be one of the major waste management policy instruments that support the implementation of the European waste hierarchy. Its application may assist in fostering the collection and recycling of waste streams that contain plastic. This paper presents an overview of the problems posed by plastic waste, and outlines their environmental dimensions. It discusses the role of the Extended Producer Responsibility principle and provides some recommendations that may be useful in enhancing extended producer responsibility.

    Smarta styrsystem kontra statisk belysning2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Lighting is an essential part of a functioning society. The development of lighting is constantly advancing in order to be as user-friendly as possible. Illumination can predict how spaces are used, using information from other luminaires, so that the area is illuminated even if the user moves exactly on the border of the illuminated area. Obtaining an energy-efficient lighting together with daylight without sacrificing visual comfort is an important issue for lighting buyers. However, visual comfort is more complicated than energy saving, as it means more factors and the favorable result is more difficult to estimate. Visual comfort, such as room perception describes how we see a room's size and shape. Something to keep in mind is that the room is not always perceived as planned and intended. Today energy-saving control systems are becoming increasingly important in commercial buildings as there is a high potential to reduce energy consumption. In addition to saving energy, smart control systems can also be used to improve light quality and increase productivity. This thesis examines how smart control systems can change the visual room perception in offices, as well as how energy consumption is affected by control systems, versus static lighting.

    The thesis is based on two questions. To answer the first question that deals with room perception, the study is based on a quantitative approach in the form of a digital survey. The survey covers how office lighting is perceived by staff at different companies using smart control systems compared to those using static lighting. The purpose of the survey was to find out the test persons' perceptions of the lighting in their office. The test subjects were given answers based on their own perceptions and values. A total of 37 people answered the survey. The second question is about energy consumption, which is calculated from a luminaire from Aura Light. The study is based on comparing the luminaire, when it is static with 100% flux and then when it is connected to a control system, so as to be able to compare the energy consumption.

    The conclusions drawn in the study of the result of the room perception show that some differences existed. The majority of those who had static lighting perceived the room as general and bright, while the majority with control systems perceived the room as calm and pleasant. This indicates that control systems can to some extent have an impact on how people perceive a room's character together with the lighting. Regarding the result of energy consumption with control systems versus static lighting, it shows that there is definitely potential to save energy when changing lighting systems in offices.

    Mapping Drainage Ditches in Forested Landscapes Using Deep Learning and Aerial Laser Scanning2023In: Journal of irrigation and drainage engineering, ISSN 0733-9437, E-ISSN 1943-4774, Vol. 149, no 3, article id 04022051Article in journal (Refereed)
    Abstract [en]

    Extensive use of drainage ditches in European boreal forests and in some parts of North America has resulted in a major change in wetland and soil hydrology and impacted the overall ecosystem functions of these regions. An increasing understanding of the environmental risks associated with forest ditches makes mapping these ditches a priority for sustainable forest and land use management. Here, we present the first rigorous deep learning-based methodology to map forest ditches at regional scale. A deep neural network was trained on airborne laser scanning data (ALS) and 1,607 km of manually digitized ditch channels from 10 regions spread across Sweden. The model correctly mapped 86% of all ditch channels in the test data, with a Matthews correlation coefficient of 0.78. Further, the model proved to be accurate when evaluated on ALS data from other heavily ditched countries in the Baltic Sea Region. This study leads the way in using deep learning and airborne laser scanning for mapping fine-resolution drainage ditches over large areas. This technique requires only one topographical index, which makes it possible to implement on national scales with limited computational resources. It thus provides a significant contribution to the assessment of regional hydrology and ecosystem dynamics in forested landscapes.

    Analyzing human factors and complexities of mining and O&G process accidents using FRAM: Copiapo (Chile) and FPSO CSM (Brazil) cases2023In: Process safety progress, ISSN 1066-8527, E-ISSN 1547-5913, Vol. 42, no S1, p. S9-S18Article in journal (Refereed)
    Abstract [en]

    The study presented in this research is a systematic human factors approach comparing two striking process accidents in Latin America: the Copiapo mining accident (2010), at the San Jose copper-gold mine, in Chile, and the FPSO CSM accident (2015), at Camarupim offshore oil field, in Brazil. Despite being different industrial segments-mining and O&G-more similarities than differences were observed in the treatment of process safety anomalies, especially those related to major accidents. The intense interactions between workers, equipment and processes, in both industries, have been making significant developments in the edge of innovation and technology, however increasing the complexity of risks in the workplaces. Furthermore, the differences between the preparation and handling of emergency situations show how complex, and critical, process safety is in these industrial areas. Aiming to adequately evidence how this complexity is intrinsically part of the various system that form the entire process, the FRAM (Functional Resonance Analysis Method) was utilized to model and analyses both accidents, under a human factors approach. Interactions and interrelations between LOPC, nontechnical skills, resilience and technical procedures were noticed as crucial for process safety and productivity of daily operations, as well as the preparedness for emergency situations.

    Human factors approach to process safety in the offshore area using FRAM2020In: 2020 AIChE Virtual Spring Meeting and 16th Global Congress on Process Safety, American Institute of Chemical Engineers, 2020Conference paper (Refereed)
    Abstract [en]

    The offshore exploration, drilling, and production, in O&G industry, are one of the most necessary activities of human Society. However, since its beginning in North America, the process variables - such as temperature, pressure and depth - have increased their operational parameters considerably, leaving the 21 meters deep, on land in 1859, extremely remote from the 6.500 meters in offshore area of Brazil Pre-Salt. To drill a subsea well and raise the crude oil to a platform, by itself, presents a series of risks that compromise the Process Safety of the entire plant. Avoiding a loss of containment, in addition to being inherent to safety itself, is also in the interest of the environment, production control and workers' health. In this sense, understand the safety barriers, as well as comprehend the Human Factors involved in Process Safety, not only brings operational reliability to the plant, but also meets the requirements of the legislation and increases productivity. In this research, a FRAM was developed to analyze a loss of containment of an FPSO storage tank, showing the importance of a systemic understanding of Human Factors in Process Safety, acting as an effective barrier to the security of the entire process.

    Åtgärder för att energieffektivisera befintliga industrilokaler vid renovering av klimatskal2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    It’s necessary to make existing buildings more energy efficient in order to reduce the energy consumption in Sweden. There are also existing premises in the country which are in need of reduced energy consumption. Initiatives on energy efficiency takes place continuously. Particularly in residential buildings. When the energy consumption is to be reduced in industrial facilities, the focus is on reducing the consumption of the internal processes. The building envelope where the transmission is a major energy leakage is often forgotten. The purpose is to increase the knowledge of energy-efficient renovation of industrial facilities. The project Dalern is an industrial facility which was built in Åland in 1990. The building is used in a case study of improved technical solutions.

    Three following questions are covered by this report.

    Which methods are available to make the building envelope of industrial facilities more energy efficient?

    Which options are most energy efficient?

    Which technical solutions would work in the project Dalern?

    A literature study of common, energy-saving renovation techniques has been implemented to answer the questions above. Document studies have also been implemented on the project Dalern. The document studies have resulted in a case study where different actions have been calculated to see what potential there is to improve the energy efficiency of the building envelope.

    The result that has emerged from the work is that there are many different methods to improve energy efficiency, especially in residential buildings. The actions that provide the most energy efficient savings are primarily replacement of windows and doors as well as additional insulation of walls and roofs. In the case study, various actions have been calculated using hand calculations and with use of an energy calculation program called VIP-Energy. Structures, meetings between building components and the entire reference object’s energy consumption have been calculated. Heat transfer, thermal bridges and specific energy has been calculated with care since the report’s emphasis is energy efficiency. Other factors that has been taken in consideration are moist, air leakage and fire.

    The calculation in VIP-Energy has resulted in the reference object’s average heat transfer can be reduced by about 30 % when using the correct actions. The reference object’s specific energy consumption can be reduced by approximately 33 %. These reductions were affected only by actions that concern the building envelope.

    Smart versus conventional lighting in apartments - Electric lighting energy consumption simulation for three different households2021In: Energy and Buildings, ISSN 0378-7788, E-ISSN 1872-6178, Vol. 244, article id 111009Article in journal (Refereed)
    Abstract [en]

    For residential environments, energy-reducing strategies to cope with user activities and behaviour are currently limited mainly to the implementation of improved lighting technology. Non-residential environments have already been operating smart lighting systems for many years. These systems use advanced and integrated lighting technology, including an internet-based network for data communication. As user activities and behaviour in the residential sector significantly differ from the non-residential one; thus, a non-residential energy optimisation potential may not necessarily be achievable and directly translatable to the residential sector. Also, the architectural typological variety amongst residences may be larger than non-residences. In residential buildings, the effect of the composition of a household (domestic establishment) and user activities on smart lighting systems’ consumption and efficiency are not explicitly investigated before. In this light simulation study in Sweden, the electric lighting energy consumption for a two-room apartment was modelled for three different household scenarios using DIALux Evo and DIVA-for Rhino. The household scenarios were composed based on input by 12 existing Swedish households and incorporate residential occupancy variety. The study’s findings suggested that the appropriate use of smart lighting solutions, including optimised sensor applications, has the potential to save more than 50% of electric lighting energy consumption compared to non-smart systems. The study demonstrated promising simulation results specifically focussing on (smart) lighting application alternatives in the residential sector.

    Emotional Intelligence in the Workplace: A study on Emotional Intelligence in Workers’ Occupational Health, Safety and Environment (HSE) in the workplace2020Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Work-related accidents emerge from potential hazards that can cause different negative outcomes in different situations. Human errors are specific actions that can either directly (active errors) or indirectly (latent errors) cause an accident in the workplace. Nowadays in order to establish an applicable system in the way of maintenance and preferment of a work environment without any accidents that are trying to develop the HSE system. In fact, this management system has been using as a significant tool to control and improve the performance of health and safety and the environment in all development programs of industries and organizations. In this term, one of the important perspectives of HSE management is Emotional Intelligence which deals with the management’s ability and safety performance in the workplace.

    The purpose of this study is to investigate the relationship between Emotional Intelligence and Occupational Health, Safety and Environment (HSE) management in the workplace, to reduce industrial incidents of human factors. Therefore, there is a requirement for a better understanding of how Emotional Intelligence factors influence health and safety performance in the workplace.

    A qualitative study has been done to achieve this purpose. In this case, data has been collected through eight semi-structured interviews with HSE managers and officers that participated from different industries around the world.  The main focus of this collection data was extracting the perspectives of the individual’s views. Afterward, to create a theory, the data has been analyzed according to different steps for a grounded analysis regarding discovering how the Emotional Intelligence factors of employees impact their health and safety performance in the workplace.

     

    The results of this study have shown that there are mainly two areas to study which are key roles of Emotional Intelligence in safety performance and key roles for effective Healthy, Safety, and Environment management. It has shown that the key roles of Emotional Intelligence in safety performance is being able to manage your own and being able to deal with other’s emotions. Besides, key roles for effective Healthy, Safety, and Environment management only three factors have been important to improve the safety act which is being able to make the correct decision in the emergency situation’ and ability to prevent incidents at the workplace as well as the level of perception of risk. These results demonstrated that strong factors of Emotional Intelligence are vital to improve the health and safety performance at the workplace and the improvement of these abilities should be approached for the workplace.

    Prosumers’ digital business models for electric vehicles: Exploring microfoundations for a balanced policy approach2019In: Digital business models: Driving transformation and innovation / [ed] A. Aagaard, Cham: Palgrave Macmillan, 2019, p. 227-254Chapter in book (Other academic)
    Abstract [en]

    Mäkinen et al. provide an indispensable view of business model opportunities for electric vehicle (EV) prosumers in the future energy market. The digitalization of energy markets has started a transformation to smart grids where information flows bi-directionally end to end between energy production and consumption. The chapter explores how prosumers can create, deliver, and capture value with EVs in future energy systems. Focusing on prosumers’ digital business models (DBMs), the chapter illustrates the complex interdependencies between various activities and actors needed in the development of an energy system. In addition to demonstrating prosumers’ EV DBMs and the current state of readiness in value creation, delivery, and capture, Mäkinen et al. develop a balanced policy approach that is based on these DBM microfoundations.

    The Value Of Environmental Sustainability: A Shared Responsibility: An exploration of B2B companies in Sweden and their costs and benefits of selecting sustainable business partners, using ISO 14001 as a point of reference.2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The business-to-business (B2B) industry stands for a significant portion of the environmental issue, yet the customer is still having price, quality, and service as major determinants for the choice of suppliers. The difficulty on how to evaluate environmental factors is hence increasingly demanding. One common and simple way for businesses to present their efforts towards sustainability is to certify their Environmental Management System with an ISO 14001 certification. Nonetheless, the question remains of the value of this premise in Sweden in our contemporary world. This study thereby investigates the value of working with environmentally sustainable business partners in the B2B market in Sweden.

    Purpose: This paper aims to explore the cost and benefits of working with environmentally sustainable business partners, using ISO 14001 as a reference point, within the Swedish B2B market. 

    Method: This study adheres to the interpretivist paradigm, with a qualitative approach. Nine semi-structured interviews with six B2B companies in Sweden were conducted and analysed via thematic analysis, using codes and emerging themes. 

    Conclusion: There are severe gaps in the ISO 14001 framework, and that one cannot trust it as much regarding the environment as intended or as much as firms do today. The real value for environmental sustainability is created when sustainable B2B firms start selecting suppliers based on their own sustainable values, not on time efficiency or costs. For a shared responsibility, firms have to evaluate suppliers based on actual and not perceived environmentally sustainable efforts.

    Responsible for responsibility? A study of digital e-health startups2019In: Sustainability, E-ISSN 2071-1050, Vol. 11, no 19, article id 5433Article in journal (Refereed)
    Abstract [en]

    Responsible innovation (RI) has received increased attention from policymakers and academics as a solution to grand challenges and is viewed as the main driver for innovation. The United Nations has suggested 17 Sustainable Development Goals and responsible innovation can be seen as a tool that allows the movement of society towards reducing inequality, coping with environmental challenges and sustaining countries&rsquo; economic and societal development. Our knowledge of how businesses act responsibly in solving these challenges is scarce. An inductive analysis of 14 e-health startups in Norway, shows that responsibility is highly prevalent. Entrepreneurs have instant contact with users (patients or healthcare professionals), which increases inclusiveness, anticipation and reflection as the main elements of responsibility. However, firms' contextual and strategic awareness of responsibility remains low, which means an absence of focused strategies to exercise responsibility. Consequently, entrepreneurial startups are prevented from reaching broader stakeholders and fully reflecting the knowledge obtained. Moreover, RI activities are often bundled with other activities on the "path" to successful commercialization. This paper contributes to and enriches the current RI understanding from a firm perspective and suggests some implications for practitioners as well as policymakers to enhance sustainable development in the healthcare sector.

    Sustainable Supply Chain Management (SSCM) Governance Mechanisms and Configurations applied in Swedish companies2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: There are several strategies that focal companies can opt for to manage their supplychain. Different combinations of configurations and governance mechanisms are argued to havedifferent sustainability outcomes. First, main firms need to decide if they manage the relationshipwith suppliers themselves or if they hire a third party. Second, the buying companies could leadthe relationship with providers by incorporating collaboration or relying on industry certificates.Besides, Swedish companies, as well as Swedish citizens, are claimed to be highly sustainable.Purpose: The goal of this project is to discover the strategies top Swedish companies implementin their supply chains regarding sustainability, and their influence on the position of the companyin the Sustainable Brand Index. As a result, this project will help to determine which specificactions are most likely to lead to increased supply chain sustainability.Method: To fulfil the research purpose, a qualitative study has been conducted. Seven case studies,consisting of five semi-structured interviews with employees from Swedish companies, and twoperipherical secondary-data based ones, were coded and analysed using the grounded analysisfollowing an abductive approach.Conclusion: The results show that the configuration framework available in the literature is notas accurate as it could be, therefore, a new one is proposed. The combination that appeared to havethe best sustainability outcomes entailed a partially closed configuration i.e., extending monitoringto lower tiers, and a spectrum in the governance mechanisms gathering focal company owninitiatives and certifications.
