Prediction models for the acoustic and vibration behaviour of lightweight steel constructions were developed in the project. The performance of lightweight double walls in terms of sound transmission was studied both experimentally and analytically. Existing models were used, but also new models were developed in order to better understand the role of the different components (boards, cavity, studs, rails etc.) in sound transmission. An accurate and fast model has been obtained by combining the wave approach and statistical energy analysis (SEA). The European standardised prediction model for calculating all building performances including flanking, which is only valid for heavy concrete structures, has been successfully adapted to lightweight structures. Airborne sound transmission through facades was also studied and some recommendations are given for designers. A group of field- and laboratory tests and numerical analyses have been carried out in order to better understand the vibration performance of lightweight floors. The harmonised test procedure to the dynamic testing and subjective evaluations of lightweight floors are proposed. Two different approaches are introduced for the assessment of vibration acceptance of lightweight floors. Different high-performance products such as facades, partition walls and lightweight floors were developed in the framework of the project. Finally, the design guide was prepared. A set of design rules for acoustic performance and vibration performance have been developed, and are included in the guide. It demonstrates that lightweight steel construction is perfectly capable of meeting modern acoustic and vibration serviceability requirements.
