Making high-efficiency lighting the new BC Liquor Branch standard

The Liquor Distribution Branch (LDB) contracted Prism to develop a new lighting design standard for their Gorge and Tillicum branch.  In their 2011/2012 Annual Report, LDB reported that these lighting upgrades contributed to energy savings of 128,000 kWh per year.

Prior to Prism’s involvement, the standard lighting design for the BC Liquor Distribution Branch was based on inefficient, deep-cell parabolic lighting.  Aware of the reduced operating costs associated with efficient lighting, paired with incentives from BC Hydro Power Smart, and the best practices suggested by the LEED certification program, LDB contracted Prism to develop a new lighting design for their Gorge and Tillicum location and future institutions.

Prism utilized lighting simulations to assist in determining a suitable luminaire for upgrades to the current design.  With Prism's guidance, LDB selected the luminaries that met their requirements for lighting levels, cost and efficiency.  The result was an energy efficient design, mainly focused improving the retail experience while utilizing higher-efficiency fluorescent and LED lighting. Controls, such as occupancy sensors in the washrooms and storage areas, were also installed to achieve additional electrical cost savings.

The LDB adopted the Gorge and Tillicum branch lighting design as their new branch standard.  Stores across the province which previously used the inefficient deep-cell parabolic design will be updated with the new design.

Results

  • Lighting upgrades contributed to energy savings of 128,000 kWh per year.
  • Savings increase with each renovation or new store.
