Manor House – North Vancouver, BC

Fortis BC Deep Energy Retrofit Pilot

Manor House is a multi-unit residential building in North Vancouver, British Columbia, constructed in the 1970s. The building was selected as one of four multi-unit residential buildings participating in the FortisBC Deep Energy Retrofit Pilot Program, an initiative intended to evaluate how comprehensive retrofits can significantly reduce energy use and greenhouse gas emissions in existing housing stock.

Retrofit measures were implemented without full building replacement and were coordinated to maintain occupancy throughout construction. The building underwent comprehensive envelope and mechanical upgrades, with suite-level ventilation integrated within an occupied residential setting.

As part of the mechanical scope, a decentralized, suite-level ventilation strategy was implemented using LUNOS e²60 Standards. The units were installed directly through the exterior wall assemblies, allowing fresh air to be delivered to individual dwelling units without introducing new ductwork or centralized air distribution systems.

Ventilation capacity was configured on a per-suite basis and coordinated with the upgraded building enclosure to support consistent operation following reductions in uncontrolled air leakage. By ventilating suites directly, the system reduced reliance on corridor pressure differentials and limited unintended air movement between dwelling units.

A centralized control solution was used to manage ventilation operation at the building level. In-suite or occupant-accessible controls were intentionally excluded, allowing facilities staff to maintain consistent ventilation performance across all suites and floors. This approach supported stable operation in an occupied residential building and simplified ongoing system management.
