Building airtightness tests have become very common in several countries, either to comply with minimum requirements of regulations or programmes, or to justify input values in calculation methods.

This report summarises the outcome of the work of the initial working phase of IEA ECB Annex 62 Ventilative Cooling and is based on the findings in the participating countries.

Systems providing space heating, ventilation, space cooling and/or domestic hot water (HVAC) to residential or commercial buildings are playing a major role in the building energy performance.

Ductwork airtightness is an input parameter in the French energy performance calculation method for new buildings (RT 2012) which influences the energy performance rating.

Since many years, several monitoring studies have shown that the quality and compliance of installed ventilation systems can be low.
