My research mainly concerns air quality, ventilation, indoor climate and building energy. The studies commonly involve the processes of spreading of gaseous and particulate contaminants, and finding efficient methods in improving the indoor air quality. The focus is often on human health, comfort and performance, but a great interest also lies in the area of building energy and its connection with thermal comfort and building preservation.
The research is performed both in laboratory and in the field, and, when applicable, involves human subjects.
CURRENT RESEARCH
- Energy saving and preservation in historical buildings: ventilation, climate control and surface soiling. Special project on churches: Energy saving in churches
