Energy efficiency in public buildings

A first step towards sustainable development and environmental protection is the carbon footprint estimation of buildings and the evaluation of their potential to decrease energy consumption. In this project, the first step for decreasing energy consumption in public buildings is described: the energy audits with in-situ measurements of 50 public buildings. The required equipment, the procedure, the difficulties during the audits and the main results of such a large number of public buildings are presented for the first time. Three of these buildings with strong social interest are upgraded in terms of energy consumption class, leading up to 90% savings of consumed energy.
