The Doig River Cultural Centre stands as a landmark project in northern Canada, marking the most northerly PHI-certified building in the country and the first certified First Nations community building. With an annual energy consumption of just 45.2 kWh/m2, the building operates at approximately 90% greater efficiency than conventional structures.

Known as the Dane che’ adliih dę’ kwą, People’s Prayer House by the people of the Doig River First Nation, it is situated in the challenging climate of northeastern BC, where heating is required for nearly ten months of the year.  Because of this, the Cultural Centre leverages a super-insulated envelope to minimize heat loss.

The Doig River Cultural Centre reflects a thoughtful intersection of cultural values, modern design, and climate-responsive construction, setting a precedent for future projects across Canada.
