Vibroacoustic performance of multi-storey buildings : A comparison of lightweight and heavy structures in the early design phase

• With the construction sector being responsible for about 40% of the energy and material use, the sector has a great responsibility for lowering the consumption if we are to succeed in our global pursuit for the green transition. However, buildings must still comply with the demands of users. For long-span, openspace lightweight, multi-storey buildings, this provides a potential risk related to annoyance caused by vibration and structure borne noise. This paper addresses the multilateral effects of building typology in terms of the vibroacoustic performance and the environmental impact. Based on an automized digital framework, multistorey buildings made of cross-laminated timber and/or concrete are modelled and compared. Finite-element analysis is used for the dynamic structural analysis, and the architectural design tool Rhino is used for material take-offs and visualisation. The aim of the paper is to provide insight into the advantages and disadvantages of different building typologies to be used for informed decision making in the early stages of design.
