Abstract
Over the last decades, residential ventilation standards have been integrated in most of the buildings codes of European countries. Contrarily to the consolidation effort in the development of the nonresidential ventilation standard EN 13779, most of the residential ventilation standards have been drafted in a prescriptive way, with disparate sizing prescriptions in the different countries. Due to these differences in ventilation requirements, the reference levels for ventilation heat loss and associated indoor air quality is different in each country. The energy saving potential for demand controlled systems is therefore different in each country as well. In this paper, the performance of natural, exhaust and mechanical residential ventilation as prescribed by the standards of 5 European countries with moderate climate is assessed with regard to perceived air quality and odour spread as well as heating season integrated ventilation heat loss using multi zone simulations with local climate data. These results are then used to calculate the energy saving potential of a demand controlled exhaust ventilation system based taking into account the trade-off between indoor air quality and heat loss. With results showing that about 50% of ventilation heat loss reductions can be achieved at equivalent indoor air quality levels, we conclude that demand controlled exhaust ventilation has a good potential for reduction of building energy use in moderate climates.
