The Arctic environment is challenging for housing mechanical ventilation and heating systems. Northern homes require effective ventilation systems to maintain acceptable indoor air quality (IAQ), occupants comfort, heath and to protect the building envelope from moisture damage.

Homes with inadequate ventilation and poor indoor air quality (IAQ) are particularly common in the Canadian arctic. Inadequate ventilation in northern and remote communities contributes to increased cases of many associated health issues. There are also a number of occupant behaviors and characteristics, such as overcrowding, specific to northern communities which can also negatively impact IAQ. These conditions may cause various health problems, such as compromised respiratory health of sensitive's occupants such as kids and may increase the incidence of airborne disease.

Effective ventilation is critically important from both a health and safety perspective for northern and remote communities. Air ventilation systems for housing in the Arctic regions have to be resilient to harsh climate, provide continuous required ventilation and accommodates for the northern indoor needs such as varying occupancy, overcrowding and indoor high activities.

The proposed session will focus on how we can do better in ventilating homes in the northern, Arctic and remote communities.  Through this session, the National Research Council of Canada (NRC), the National Institute of Public Health of Québec (INSPQ), The Institute of cardiology and Pneumology of the University Laval, the Nunavik Regional Board of Health and Social Services and the Kativik Municipal Housing Bureau (KMHB) will seek to provide the audience an overview of:

• Gain insights about HRV/ERV performance issues in Canada's near North and Far North;

• NRC's research on innovative air ventilation system for housing in the Arctic;

• NRC's research/work on ventilation and IAQ in the North.

• Collaboration Research  developed in order to improve the ventilation and indoor air quality in Nunavik homes with the goal of improving of the health of Nunavik's children;

• Research on the incidence of building characteristics and occupants behaviour on indoor air quality

• Chemical and microbiological characterization of indoor residential environment

• Influence of indoor environment quality on children respiratory health

• Mold problem in northern housing, and how to prevent mold growth.
