New areas for quality assurance

The work on new areas for quality assurance was the focus of one of the work areas.

The work covered, for instance, the development of a proposal for a definition of performance figures and system classification, as well as a description of the testing procedures for solar thermal and heat pump combined systems.

Besides, it was imperative to collect and assess data regarding solar cooling systems in operation. The work in a task relating to function and yield control for large systems (FYC-LSTS) had to be redefined, finally resulting in a report on the state-of-the-art and recommendations for a future technology roadmap.
