In Subtask C of IEA SHC Task 56 complete solar envelope systems based on active and passive components and integrated into the HVAC system are investigated on building level. Different approaches for investigating Solar Envelope Systems are required for residential and office buildings. This report has the goal to describe the different methods used for non-residential (i.e. office) and residential buildings and to give comprehensive information about the reference buildings and HVAC systems used in IEA SHC Task 56.

In Deliverable D C.4 two Demo buildings are presented. The first one is a multi-family house built in Innsbruck, Austria according to the Passive House standard. The second one is a library located in Varennes, Quebec, Canada designed as net zero energy building. Demo buildings are illustrated and monitoring results are reported.

Building Integrated Solar Envelope Systems for HVAC and Lighting includes a broad variety of technologies. Different “Solar Envelope” solutions for office and residential buildings are investigated and evaluated by means of building and system simulation. Detailed technical/economic analysis will be carried out in order to assess the impact of the integration of the solar envelope components for different buildings in different climates. Models for these technologies shall allow to develop and optimize control strategies for coupled control of indoor air quality, thermal and visual comfort (lighting) considering optimal energy performance.
