The decrees of the Ministry for Economic Development complementing the regulatory framework on the energy performance of buildings, come into force today, October 1st. The new regulations for Certification of buildings’ Energy Performance (APE 2015) are contained in the decree “Guidelines for the energy certification of buildings”: the new APE is the same throughout the country and offers to citizens, Administrations and operators more information concerning the efficiency of the building and installations, for easier comparison of the energy quality of different properties, with the aim of steering the market towards buildings with better energy quality. The energy ratings go from seven to ten: class A4 is the best and class G is the worst. It is mandatory for at least one inspection by the auditor in charge of drawing up the APE to certify the class the property belongs to. The APE must also indicate proposals to improve the building’s energy efficiency and provide information on financial incentives to implement them. Finally, the decree establishes a national database of energy certificates (SIAPE), by defining a template for sale and rental ad, that standardises the information on the building’s energy quality. The new methods for calculating the energy performance and the new minimum efficiency requirements are defined by the decree on “Methods for calculation of performance and minimal requirements”. The decree strengthens the minimal energy standards for new buildings and for renovated ones, and defines the parameters for buildings involved in mere energy upgrades (building enclosure and utility installations). However, for newly constructed buildings and for those undergoing significant renovations, the minimum requirements to be complied with are obtained by comparing the building with a reference building (identical by geometry, orientation, location, intended use). Application of the regulations is effective immediately and consistently in all Regions.
