Reducing energy consumption for ventilation in dwellings through demand controlled ventilation

The Danish Building Research Institute has initiated a 3-phased research programme whose aim is to develop energy-efficient ventilation strategies to provide a healthy and a comfortable indoor climate and to reduce energy consumption . In this article, the second phase of the programme is presented. Investigations were conducted in an almost full-scale apartment built inside a laboratory hall. Two out of four scenarios were investigated, one that complies with current Danish Building Regulations on ventilation, and the other with fully demand-controlled ventilation. The results are presented.
