100%solarLCA – Life cycle analyses of different concepts for 100% solar heated buildings

The seasonal storage of heat in 100 % solar thermal heated single and multifamily buildings has been implemented in a number of projects in Switzerland. The first multifamily building with seasonal thermal energy storage that uses a combination of PV and heat pump instead of a solar thermal system is currently being built in Benzenschwil (AG/CH). In this project, concepts with solar thermal, solar electrical and combined solutions for 100% solar heating are compared, wherefore the entire lifecycle (LCA) of the different system is considered.
