Benefit of the new financial assistance plan

  • Increase of $162,270, or an increase of 189% compared to previous plans.

Benefits of the measures and program

  • Heating
    • Reduced heating needs due to improved thermal envelope efficiency
    • Reduced power demand due to the thermal storage unit
  • New cooling system
    • Less electricity used for air conditioning
  • LED lighting
    • Guaranteed energy efficiency of LED fixtures qualified by DesignLights Consortium
    • Up to 70% less electricity used when lighting with DLC Premium light fixtures and adaptive controls as compared to the market benchmark
  • 100% fresh-air intake system
    • Reduced heating costs through heat recovery and installation of a VFD with a CO2 sensor
  • Reduced domestic hot-water heating costs due to heat recovery systems
  • Simplified financial assistance calculation with the OSE tool [EXE 13 MB – in French only]
