Energy efficiency

Having access to a single window for testing your products and renewable energy systems

Directive 2012/27/EU on energy efficiency imposes to have significantly reduced energy consumption by 2020. On the other hand, RT 2012 (French thermal regulation for buildings) encourages the use of renewable energies to reach a primary energy consumption of 50 kw/H/m2/year. In order to get such results, one needs to shrewdly combine renewable energy products and systems that are perfectly optimised.
