Sustainability Report
Operational Emissions / Energy
Photovoltaic system: The roof was redesigned to optimize future solar panel installation. Once installed, the 7.5 kW array will allow the building to generate more electricity than it consumes, targeting net-positive energy operation.
High-performance envelope: The walls were upgraded with R-29 cavity insulation and continuous rigid insulation on the exterior, while the roof was insulated to R-49 with continuous rigid insulation, greatly improving thermal performance.
Energy-efficient glazing: Loewen windows with LowE366 glass and PHIUS-certified sliding doors significantly cut heat loss and solar heat gain, reducing the need for mechanical heating and cooling.
Passive solar design: The building massing and the repositioned roof slope optimize solar gain during winter while providing shading during summer, reducing heating and cooling demands.
Radiant heated concrete floors: Hydronic radiant systems operate more efficiently than forced-air systems, providing comfortable heating at lower energy intensities.
Rainscreen facade: Deep-set windows and ventilated siding reduce overheating from direct sun, especially on south and west facades.
Service and maintenance emissions
The renovation focuses on reducing embodied carbon by retaining the original structure and minimizing demolition waste. New construction elements, such as the cedar-clad addition and south-facing dormer glazing, employ high-performance building assemblies to improve thermal efficiency. Materials were selected for durability and low maintenance, extending the building's lifespan and reducing resource consumption over time.
