This video is from the International Energy Agency (IEA) Annex-62 Ventilative Cooling Seminar held at Brunel University London on the 17th September 2014.
Ventilative cooling is the use of natural or mechanical ventilation strategies to cool indoor spaces. It can significantly reduce the cooling energy demand in summer or mid-season conditions.
Over the past few years, there has been an increasing number of airtightness tests performed in Europe either for specific high performance buildings programmes or for a wide range of buildings in regulatory contexts.
While building airtightness is a key concern in Nearly Zero-Energy Buildings in most European climates, there exists already a wide range of commercially-available products specifically designed to minimise leakage in building envelopes.
The implementation of the EPBD recast puts increasing pressure on the market to achieve better building and ductwork airtightness: for most European climates and countries, good airtightness levels are necessary to achieve nearly zero-en
