Ingenium started an energy bookkeeping system for a total of 250 public buildings. In addition, energy audits were performed for 105 large public buildings (including museums, concert halls, office buildings, research centres, accommodation centres, etc.), resulting to the definition of the principal energy saving measures and investments.
In connection to this study, Ingenium provided guidance for the execution of some energy saving projects. In particular, Ingenium established standard specifications for maintenance of the HVAC systems.
