Bridge River Generating Stations 1 & 2

Bridge River Generating Stations 1 and 2 were built in 1948 and 1960 respectively comprising almost 13,000 square meters of conditioned space including outbuildings. SES was commissioned to conduct detailed Energy Studies on both buildings in 2011. Recommended measures included:

  • New DDC systems
  • Compressed air system leak repairs
  • Building envelop remediation work
  • New air source heat pumps
  • Replacement of electric radiant heaters
  • Lighting upgrades and re-lamping
  • New lighting controls

These projects are projected to reduce the energy footprint at Bridge River 1 by 46 per cent with just over 7 years simple payback. Bridge River 2 is anticipated to save 50 per cent of its energy footprint, also with just over 7 years simple payback.

BC Hydro Surrey Campus

SES completed detailed energy audits for BC Hydro’s Surrey Campus, consisting of 13 buildings with specialized uses including warehouses, automotive service shops, paint booths, storage yards, and wood working shops.

Our conservation measures focused on the installation of DDC control and optimization of existing systems, heat pump installations, occupancy sensor controls, heat reclaim, lighting retrofits and re-lamping, building envelope upgrades, variable speed drive installations, and low flow water fixtures. To ensure persistence, and encourage conservation behaviour, we have recommended web based real time energy and water monitoring with interactive dashboard displays at all sites, and the creation of a BC Hydro Conservation News Network to promote continuous improvement, friendly competition, and celebrate success.

In addition to our primary mandate to identify and evaluate conservation measures, we were also asked to recommend ways to demonstrate new technologies to BC Hydro staff and customers. We analyzed many innovative ideas for the SC including:

  • Rain water capture for vehicle washing
  • Solar building heating
  • Solar domestic hot water
  • Variable refrigerant flow system
  • Geothermal heat pumps
  • Solid oxide fuel cells
  • Installation of skylights to reduce lighting density
  • Green re-roofing.

Tsawwassen Ferry Terminal

SES completed an energy study for the Tsawwassen Ferry Terminal, operated by BC Ferries.  The study described the current energy consumption of the facility and identified several energy conservation opportunities.  Consisting of approximately 11 buildings, the terminal presented an interesting challenge due to its specialized nature and intermittent use.

Vancouver Island Technology Park

A continuous optimization study performed on Vancouver Island Tech Park representing 15,613 m2 of total floor space.  VITP is a research facility managed by the University of Victoria and contains both wet and dry laboratories.  Several energy conservation measures were identified including:

  • Demand controlled ventilation
  • Weather prediction for heating system control
  • DDC exterior lighting control
  • DDC integration of access control
  • Heat recovery between hot deck and cold deck
  • Optimized system scheduling
