A simplified tool based on the Energy Performance of Buildings Directive algorithms will be elaborated. As this simplified tool will be mainly dedicated to installers, a special attention will be paid to the easy to use, and the ergonomic.

At the end of the project, the design guidelines for manufactures based on the different work package results will be provided. This document will then be presented to manufacturers thanks to the dissemination activities.

As a result of this project, some recommendations for the subsidy scheme to national and local authorities will be produced, and the energy savings potential of solar combisystems in Europe will be evaluated.
