Purpose: Sound and fire are two areas in which additional challenges in high building
structures with wood need to be carried out. The planning stage often requires greater
efforts for architects and engineers to solve technical requirements for buildings with
wooden frames over traditional solutions with concrete. The design decisions get more
complicated with prefabricated wooden elements that are difficult to handle. This leads
to poor management early in the construction process that creates problems.
The goal of this essay is to examine how the design of apartment buildings with wood
and concrete structures of prefabricated elements are affected by sound and fire
Method: A qualitative study has been conducted with interviews as a base. It has been
supplemented by document analysis. In order to compare two apartment building
projects, Limnologen and Strandparken, with a fictitious concrete structure, a
comparative study has been carried out.
Findings: The technical solutions do not affect the design in a problematic way. The
technical solutions solve problems without being problematic during the design process
for architects. It is mainly the timber floors dimension that becomes larger and thus
higher floor height, to solve noise problems. Architects should have knowledge about
this early to avoid a disproportional design of the building.
Generally, more knowledge is needed in the construction and design process and the
aspects of the projection and construction phase with wooden frames need to be taken
Implications: The effects of large dimensions will be slightly larger wooden timber
floors and impact the storey height. It leads to greater distances between floors and
creates a different design expression of the facade.
Limitations: This work is limited to only apply to apartment buildings with eight
floors. For best results to apply, the buildings must have a frame of solid wood.
Keywords: Wooden frames, wooden buildings, solid wood, vibration and structureborne
sound, airborne sound, the design of wooden buildings, noise problems, fire
problems, Strandparken, Limnologen.
