The Merivale Gardens project in Ottawa involves retrofitting a one-story building with an attached garage, constructed in 1987 and requiring window replacement. The project tackles challenges to achieve net-zero performance through a conservation-first methodology.

Key objectives achieved:

1. Retrofitting to EnerPHit standard, achieving a space heating demand of 30kWh/m2/year, leading to substantial reductions in heating demand, operational emissions, and energy costs
2. Mitigating condensation and preventing mold growth.
3. Enhancing comfort, thermal resilience, and passive survivability
4. Improving aesthetics, and property value, and replacing outdated siding and fenestration systems
5. Prioritizing sustainable materials
6. Wood’s first approach
