Handel Architects Completes Canada’s Largest Passive House Building 

Harmony Commons, a dormitory building at the University of Toronto Scarborough, has been officially recognized as a Passive House project, making it the largest of its kind in Canada. The building, designed by Handel Architects, houses 746 first-year students and includes a dining hall and office spaces. 

Strategic Design for Energy Efficiency 

Located in the northern part of the campus, Harmony Commons is composed of three volumes arranged in a U-shape, with a central courtyard raised above the dining hall. The courtyard, bordered by glass walls, serves as a focal point, connecting the interior spaces with the surrounding natural environment. 

Passive House Certification 

Completed in 2023, Harmony Commons has achieved Passive House certification from the Passivhaus Institut in Germany. This certification, which marks it as the largest Passive House building in Canada, also distinguishes it as the largest dormitory globally to receive such recognition. 

High-Performance Building Envelope 

To meet Passive House standards, the building employs a high-performance envelope, low-energy systems, and heat recovery from both ventilation exhaust and wastewater. It operates on all-electric power and features windows optimized for natural light while minimizing heat loss. 

Significant Energy Savings 

Compared to a similar dormitory built in 2003, Harmony Commons uses approximately 70% less energy during peak heating conditions. Additionally, the building’s consistent energy use throughout the year contributes to reduced costs and less strain on the electricity grid.
