Feasibility study of prefabricated multi-active facade elements for energy renovation of multi-family buildings

In order to meet the Swedish energy and climate targets for 2020 and 2050, the existing building stock needs to be addressed. Multi-family buildings from the "million program" are in need of refurbishment however there is no demonstrated cost-effective solution for a comprehensive energy renovation. The aim of this project is to investigate requirements and develop a cost-effective and large-scale applicable concept for facade renovation of Swedish multi-family buildings based on prefabricated multi-active facade elements with integrated systems for ventilation, heat recovery and renewable energy.

A feasibility study (technology mapping, architectural criteria, energy and economic calculations) and concept development of the above facade elements will be carried out. The main participants are LTH and NCC with close support from a broad and experienced reference group. The project is part of an IEA research project on multifunctional facades (IEA SHC Task 56 Building Integrated Solar Envelope Systems for HVAC and Lighting) and the results will be presented in Sweden and abroad.
