What is the CECB®?

The Cantonal Building Energy Certificate (CECB) is an eco-rating program recognized by all Swiss cantons. The information contained in the certificate can be used for appraisal purposes and to pinpoint potential energy-efficiency improvements. The certificate shows:

  1. The energy efficiency of the building envelope
  2. The amount of energy needed to run the building under normal conditions.
