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 48% less electricity used when lighting with DLC Premium light fixtures compared with the market benchmark
- Save even more with adaptive controls designed to adjust lighting to meet needs
- 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
