Energy calculator (France)

In this part you can calculate annual energy demand of your property and compare annual expenses of different fuels. You can change values in green fields, and made changes counter calculates automatically. Additional information you will get by taking the mouse cursor on exclamation mark.

The calculator was developed as part of BioHousing project by Jyväskylä University of Applied Sciences in co-operation with project partners and Atlantis Consulting Ltd.
