In energy balance of buildings the ventilation losses are a big part, and this part is getting relatively bigger the better the enclosure of the building is insulated. All ventilation that is larger than what is wanted for hygiene and comfort can be regarded as undesired and thus be considered as heat loss. For energy conservation it is therefore essential that ventilation rate can be controlled. This report discusses the current research in Sweden dealing with air infiltration. This research is divided into five subgroups: Nomenclature, System Analysis, Measurment and Testing Methods, Technical Solutions in Design, and Influence of Microclimate.
