Benefits to the measures and program

  • Heating
    • Reduced heating needs due to thermal envelope efficiency
  • Heat pumps
    • Environmentally friendly heating and air conditioning through the extraction and transfer of heat and cold between the indoor and outdoor air and ground
    • Reduced heating and air conditioning costs
  • LED lighting fixtures
    • Guaranteed energy efficiency of LED fixtures qualified by the DesignLights Consortium
    • Up to 48% less electricity used when lighting with DLC Premium light fixtures compared with the market benchmark
    • Save even more by installing occupancy sensors
  • 100% fresh-air intake systems
    • Reduced heating costs through heat recovery and installation of a solar wall, variable-frequency drive and CO2 sensor
  • Reduced domestic hot-water heating costs by installing heat recovery systems
  • Easy to estimate financial assistance with the OSE tool
