The Challenge: Unreliable Traditional EPCs

Previously, EPCs relied on estimated air leakage values. These estimations often underestimated the actual amount of air leakage in existing buildings, resulting in inaccurate EPC ratings. This can have significant consequences.

Imagine a building owner who installs a less efficient heating system based on an inaccurate EPC that suggests good energy performance. In reality, due to high air leakage the building might lose a significant amount of heat. This negates the benefits of the new system and can hinder sustainability goals.

Air tightness Testing: The Solution for Accurate EPCs

Air tightness testing is a non-destructive method for precisely measuring a building’s air leakage rate. It is done by pressurising the building interior slightly and measuring the rate at which air escapes.

The valuable data allows building owners or professionals to:
