High energy performance

In the French building sector, the Hautes Performances Energétiques (HPE, or high energy performance) label is an incentive to surpass the requirements of current legislation by reaching an even better energy efficiency.

Based on the 2005 thermal regulation (RT 2005), the HPE label is obtained by reaching an average energy consumption 10% lower than that required by the RT 2005.

An HPE house will therefore have an average energy consumption of 100 kWh/m²/year.

A variation of this label exists: the HPE Enr label. In this case, the building must comply with the constraints of the HPE label and use a renewable energy source for its heating or hot water production:

• either a biomass boiler that covers at least 50% of heat production;
• or a connection to a heat network powered by at least 60% biomass.
