SLAVE LAKE RECREATION CENTRE ENERGY AUDIT

The Multi-Rec Centre is a multi-purpose recreation facility in the town of Slave Lake, Alberta. The building houses two ice rinks, a fieldhouse, dressing room facilities, concession, retail space, and offices. The Multi Recreation Centre is Slave Lake's largest multi-sport facility and offers many programs and services to enhance the quality of life of the people of Slave Lake and the surrounding communities.

Clark Engineering was retained by the Town of Slave Lake to conduct an energy audit at the facility to MCCAC and ASHRAE level 2 standards. Typical scope of work for energy audits are as follows:

  • Building knowledge download – get to know the building inside and out:
    1.  Building envelope construction methods
    2.  Building heating, air conditioning, and ventilation systems
    3.  Building process equipment
    4.  Lighting systems
    5.  Electrical plug and miscellaneous loads
  • Utility billing history review – month to month analysis of utility consumption and costs
    1.  Electricity billing history
    2.  Natural gas billing history
    3.  Other fuels billing history
  • Energy use breakdown assessment – quantify energy use within the building systems
    • Energy conservation measure proposals – propose energy conservation strategies based upon acquired knowledge of the building systems and energy use intensities

    Energy conservation measure proposal highlights:

  • Building management system improvements – 280 tonneCO2e reduction/year
  • Exhaust system heat recovery – 50 tonneCO2e reduction/year
  • Ice plant heat recovery – 110 tonneCO2e reduction/year
  • Combined heat and power plant – 150 tonneCO2e reduction/year
  • LED lighting upgrades – 100 tonneCO2e reduction/year
  • The complete suite of energy conservation measures recommended would result in a projected energy use reduction of 45%.

    The energy audit was completed in early 2020 and Clark Engineering and Town of Slave Lake look forward to the implementation phase.
