Recommissioning (RCx)

Recommissioning (RCx) is the reoptimization of existing buildings, in order to improve the occupant’s comfort and save energy. Thanks to the RCx, the overall energy consumption of a building can easily be reduced by 5 to 15% with a minimal investment, allowing a return on the investment of generally 3 years.

The RCx is one of the first steps to take to improve the performance of a building, since it allows to:

  • Optimize energy efficiency and the building’s operations?;
  • Improve energy management’s demand during peak periods;
  • Ensure the sustainable development and operations of buildings;
  • Identify possible investments to further improve the buildings energy efficiency.
