In general and 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 both in summer and shoulder seasons due to the increased airtightness, insulation levels and solar gains of these high performance building structures. Proper building design strategies can overcome this risk of overheating with little or even no use of active cooling. These strategies include in particular ventilative cooling (i.e. use of ventilation to cool indoor spaces), adequate solar control (dynamic shading) and thermal mass utilisation. In this position paper the Venticool initiative appeals to standard writers and policy makers to provide fair and easy evaluation of the performance of ventilative cooling systems in standards and regulations.
