As it is now a well-known fact that air leakage can significantly impact the building energy performance, more and more countries are introducing requirements or recommendations on new buildings’ airtightness level in their energy performance regulation. One key aspect to encourage good practice and good airtightness levels in new or retrofitted buildings is to properly include the air infiltration impact in the EP calculation.
