- Lighting controls
- Heat wheel (heat recovery from fresh air)
- VSD‑equipped 100% fresh‑air HVAC systems
- Thermal storage unit (hot water storage tank) for power management
- Drain-water heat recovery
- Additional roof insulation
- Windows covering 800 m2
Area of activity

By helping its customers implement a similar project, the partner or aggregator could receive approximately $50,000 in incentive compensation.
Benefits of the measures and program
- 10% multi-measure bonus resulting from the combination of heat recovery systems, roof insulation, and fenestration measures.
- 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 lighting 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 support calculation with the OSE tool
