Canada’s most Eco-Efficient Building
The University of Toronto Scarborough is one of Canada’s most “eco-efficient buildings”
University of Toronto Scarborough new student residence is a 9-storey U-shaped massing with 340 dormitory suites and single two-bedroom apartments will accommodate some 747 students with retail at grade. The building was designed specifically with the first-year student experience in mind with durable materials and furnishings that were also easily maintained. The community-focused design includes an integrated dining hall, common lounge, study space on each floor, an outdoor roof garden and terrace, a community kitchen, and a laundry facility.
In keeping with the green design the site has no vehicular parking, but does include 100 bicycle parking spaces. By adhering to these principles, UTSC Passive House is designed to be highly energy-efficient, comfortable, and sustainable, providing significant benefits over conventional construction methods, including lower energy bills, reduced environmental impact, and improved indoor air quality.
Prime Consultant Role
CORE acted as Executive + Architect for a Bridging Contract Document delivery method, where Architectural design work advanced to approximately 90% of the Construction Document set. CORE served as the Prime Consultant, retaining all disciplines for the design phase. Deliverables included submission and approvals for Zoning Bylaw Amendment, Site Plan Approval, construction documents, tender and bid and award, construction administration, closeout, Passive House Accreditation.
Passive House Accreditation
Designed with fully accessible housing and designed to the highest energy efficiency standards, comfort and sustainability, including Passive House accreditation. Designing a Passive House focuses on creating buildings that are ultra-low energy, requiring little energy for space heating or cooling.
Measurable Passive House Standards
The project will be constructed to U of T’s Passive House (PH) Classic Standards which will include:
- Super-Insulation
Goal: Minimize heat loss through the building envelope.
Strategy: Use high-performance insulation materials in walls, roofs, and floors. The insulation levels often far exceed standard building codes.
- Airtight Construction
Goal: Prevent uncontrolled air leakage.
Strategy: Implement meticulous airtightness measures to eliminate drafts and ensure that the heat recovery ventilation system operates efficiently.
- Thermal Bridge-Free Construction
Goal: Avoid thermal bridges that can cause heat loss.
Strategy: High-performance building envelope that is tightly sealed, robustly insulated and contains no metal to metal conditions (to prevent thermal bridges). - High-Performance Windows and Doors
Goal: Maximize solar gain and minimize heat loss.
Strategy: Use triple-glazed windows and insulated frames, carefully positioned to take advantage of solar energy while minimizing energy loss.
- Heat Recovery Ventilation
Goal: Ensure fresh air without letting heat escape.
Strategy: Install a heat recovery ventilation (HRV) system to supply constant fresh air, recovering heat from the exhaust air to warm incoming fresh air. - Optimizing Solar Gain
Goal: Utilize the sun’s energy for natural heating.
Strategy: Orient the building and windows to capture maximum sunlight during the winter months while minimizing overheating during the summer through shading or other passive strategies. - Energy Modeling and Performance Testing
Goal: Ensure the design meets Passive House standards.
Strategy: Use software tools for energy modeling and perform blower door tests to measure airtightness. - Sustainable Materials and Practices
Goal: Reduce the environmental impact of the building materials and construction process.
Strategy: Choose low-impact, sustainable materials that have minimal environmental footprints. Employ construction practices that reduce waste and promote sustainability.
