Abstract
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. Report DC.1 gives general information about benchmarks, simulation models of the reference buildings as well as, reference locations and climate analysis, and finally Key Performance Indicators (KPIs). Additionally, an overview of the features of different simulation platforms is given.
