Vancity - Head Office
Heat Recovery Project
In 2014, Vancity engaged SES Consulting to replace the aging boiler plant in their head office, a 12 storey office building. The building houses offices for management, administration and other support staff as well as a large data centre with year-round cooling needs. SES proposed installing a heat recovery chiller, which had the potential to capture the waste heat from the data centre to heat the entire building, eliminating 95% of the annual natural gas consumption.
The heat recovery chiller was installed in August 2014, and has reduced Vancity’s natural gas consumption by 5,000 GJ and GHG emissions by 75%, with a simple payback of 4.5 years. This pioneering project was featured in a recent edition of the APEGBC Innovation magazine.

Central Plant Upgrade
This project was to replace an aging boiler and chiller with a new heat recovery chiller/boiler combination in a 50,000 sq ft office building. The project was one of the first heat recovery chiller retrofit installations in BC, allowing the building to move excess heat from one part of the building to other areas that needed it. The upgrade of the central plant and subsequent recommissioning of the building systems reduced natural gas consumption by over 80% and electricity consumption by 30%. This reduced the annual GHG emissions by approximately 85 tons.
BC Hydro - 333 Dunsmuir
This project involved a comprehensive energy study of BC Hydro’s corporate headquarters in downtown Vancouver. The building is an 18 storey office tower, including a large underground parkade. The energy study identified opportunities for BC Hydro to demonstrate leadership and innovation in energy conservation. Working closely with BC Hydro, SES identified opportunities to reduce total energy consumption by 43% and GHG emissions by 73%. Projects identified include an upgrade and optimization of DDC controls systems, installation of variable speed drives, heat recovery, and extensive lighting upgrades.

Building Automation Design
This building houses offices as well as a data centre which requires cooling year round and makes the building very energy intensive. A DDC system upgrade and conservation measures helped this 1970’s building achieve new energy savings; the cooling demand was lowered by reducing run times and optimizing free cooling. Night time set-backs and occupancy demand schedules reduced energy waste during low occupancy hours.
SES provides energy efficiency engineering services for Morguard in Alberta, British Columbia and Manitoba. We have completed energy studies, designed and optimized DDC systems and chiller plant upgrades, as well as working with staff to verify savings outcomes and train operators.
