The “By law on Energy Performance of Buildings” by the Ministry of Environment and Urbanization will require buildings to meet the minimum performance criteria and standards concerning architecture, heat insulation, heating and cooling systems and electrification. According to this regulation, an “Energy Performance Certificate” is given starting in January 2011 in order to give information on energy expenses and CO2 emissions for new buildings and buildings that have been purchased or rented. Utilisation licences will not be granted to new buildings that receive less than a “D” class rating. Furthermore, central heating is compulsory for new buildings of more than 2 000 m2. As of September 2014, the number of buildings with Energy Performance Certificates was 210 402.
