Energy Efficiency Upgrades to Mechanical Systems

A group of Co-Operative buildings retained TrinityEng to assess the complete HVAC and Plumbing systems throughout each building, providing options and recommendations for energy-efficient retrofits.

TrinityEng prepared detailed reports, identifying project budgets, forecasted annual operational savings and preventative maintenance plans. TrinityEng performed the complete design, tender, permit and construction administration process.

The projects involved the installation of new high-efficiency condensing heating boilers and instantaneous DHW heaters, high-efficiency make-up air units, high-efficiency exhaust fans with variable controls and domestic cold water booster pumps complete with variable frequency drives.

Following the installation, the Client enjoys an annual electricity use reduction of 75,000 kWh and an annual natural gas use reduction of 110,000 m3. This amounts to over ~$65,000 in annual operational savings.

TrinityEng secured and obtained for the Client a combined incentive of $120,000 through available hydro and natural gas programs.
