What is AIVC?

AIVC (Air infiltration and Ventilation Centre) is the IEA information centre on energy efficient ventilation.

Ventilation and air infiltration into buildings represent a substantial energy demand which can account for between 25% to over 50% of a building's total space heating (or cooling) needs. Unnecessary or excessive air change can therefore have an important impact on global energy use. On the other hand insufficient ventilation may result in poor indoor air quality and consequential health problems.
