The project deals with timber floors for multi storey apartment and office buildings. In addition to that the trends towards more sustainable building concepts demands that aspects of assembling and disassembling, environmental impact, economics and multifunctionality (in terms of installations included in these elements) have to be addressed within the design of floor systems in order to create solutions that are fit for the future.There are many systems for timber floors on the market. However, a lot of them fail to really compete with massive concrete floors. The two main reasons for this are:•Economic aspects and structural composition •Acoustic performance The main objective of the proposed research project is to develop and implement multifunctional timber floor systems with improved acoustical properties and a multilevel optimization approach. These floor systems should be targeting at least dimensions that lie in the range of comparable concrete floors and at the same time perform better in terms of environmental impact. The proposed solutions should be based on timber and timber hybrid systems . Regarding the timber, the possible use of Swiss hardwoods (being a type of wood that on the one hand is currently not usable for most constructions because of static deflection and on the other hand offering promising potentials in the field of acoustics because of higher mass) in such systems shall be studied and its implementation shall be forced where possible. With this project it is planned to provide timber based floor systems with improved properties in the field of acoustics, design strength and stiffness, dynamics (vibration), economy and ecology to the market. The intention is to increase the share of timber based floors within the Swiss construction market and with this to contribute to a higher wood (including hardwood) utilization in general.With constant improvement on part of the running energy consumption the environmental impact from building materials will be of increasing relative importance in buildings LCA in the future. Within the project the relevance of the environmental impact of the floor system will be assessed in relation to (equal performing) alternatives.
