Energy efficiency solutions for
commercial buildings

  • Lighting management
  • Management of office equipment
  • Measurement
  • Monitoring and safety of infrastructures
  • High and low current

There are many sustainable development solutions for reducing energy consumption and improving the quality of the energy while maximising the return on investment of the building.

* The energy savings are given for information purposes only. The calculations are based on European standards or are the results of mathematical simulations or measurements on actual cases and have been validated by the professional associations.

 

01. Lighting management

Lighting accounts for 30% of the energy consumption of commercial buildings.

Lighting

Lighting management system and presence sensor.
Savings:
- € 1,780 a year
- 2,500 kg CO 2 a year
