Comfortable heating of rooms with large areas of external glazing is one of the most challenging issues in cold climate zones. The rule of thumb, in this case is locating the heating unit under the window.

It is no longer sustainable to look at the performance of buildings in isolation of people that use them. This paper examines what is involved in assessing how a building performs for people.

Indoor air quality is a major area of concern in northern housing and could be influenced by ventilation.
Boualem Ouazia, Chantal Arsenault, Mark Vuotari, Gang Nong, Daniel Sanders
Attached garages can pose a threat to a home’s indoor air quality because the garage air, which often contains some contaminants such as particulate matter, carbon monoxide, and volatile organic compounds, can migrate into livin

Office buildings are significant contributors to energy consumption and greenhouse emissions, and it is obvious that office building occupants and their behavior play an essential role in building energy performance.
Zuzana Veverkova, Karel Kabele
The purpose of this study is to compare capture efficiencies of cooker/range hood (CEs) under various conditions to verify that there can exist a difference between a CE by applying a pressure difference across the building enve

It is evident from the existing research that poor thermal comfort can adversely affect the health and productivity of the occupants.
Ryan Sharston, Manan Singh
Cracks in building fabric lead to air infiltration due to wind and buoyancy driven forces. In the heating season, the cold air entering the building needs to be heated up to room temperature, thus leading to an energy demand.
