In general, but in particular in nearly zero-energy buildings, there is a very strong tendency to drastically reduce the heating demand. One adverse side effect is that in doing so, it often increases the risk of overheating in summer and shoulder seasons. This is in particular, but not only, the case for lightweight constructions.
Experience shows that active cooling is too often considered to begin with, while other options should be prioritized in the building design when relevant. In fact, proper building design strategies including adequate solar control, thermal mass, ventilative cooling—i.e., use of ventilation to cool indoor spaces—can overcome this risk of overheating with no or minimum use of active cooling.
Because there is a growing interest in ventilative cooling to reduce the cooling energy demand and improve thermal comfort in summer and shoulder seasons, one purpose of the ’33rd AIVC Conference‘ was to discuss the potential, challenges and perspectives of this technique in a track of specific sessions.
This conference also inaugurated venticool, the international platform on ventilative cooling, whose aim is to accelerate the uptake of ventilative cooling by raising awareness, sharing experience and steering research and development efforts in the field of ventilative cooling.
Because venticool partners realize the valuable experience and knowledge shared during this conference which should be of interest to many professionals, policy makers, and researchers beyond the conference attendance, venticool has produced this book gathering 16 publications presented during the conference
