Building energy software tools and energy consumption

Project owners are increasingly asking for energy performance commitments to guarantee a specified level of consumption.

There are different types of energy commitments: GPEI, CPE and ERM.

• The ERG (energy performance guarantee) applies to both new-build and renovation projects, and concerns actual consumption.

More generically, these contracts are known as GPE (garanties de performance énergétique).

Energy performance commitments can cover a very broad scope, including all site consumption. However,...
