Heat accounting in residential buildings has been identified by the European Union (EU) as one of the main drivers to reduce energy consumption in the residential sector. To this aim, the European Directive 2012/27/EU and the Italian Decree nr. 102/2012 and subsequent modifications set the obligation for apartment and multi-apartment buildings supplied by a common central heating source or by a district heating/cooling network, to install, by December the 31st 2016, sub-metering systems to allow a fair cost allocation through the tenants. In Italy the obligation has been recently extended to June, the 30th, 2017. In several studies conducted in different EU Member States a very wide range of variability (8-40%) of the expected benefit of heat accounting systems has been found. Unfortunately, specific studies regarding the Italian territory and the Mediterranean climate conditions are still lacking. Nevertheless, due to the large number of buildings virtually subject to the obligation, the potential for energy savings in Italy could be among the highest in Europe. In the present study, after a brief analysis of energetic benefit of common heat accounting systems, the authors evaluate the potential impact of such systems on the energy consumption of the Italian residential building stock. To this end, the Italian residential building stock has been analyzed through both the ISTAT census 2011 and a recent statistical analysis performed by ENEA based on ISTAT data.

Abstract
Heat accounting in residential buildings has been identified by the European Union (EU) as one of the main drivers to reduce energy consumption in the residential sector. To this aim, the European Directive 2012/27/EU and the Italian Decree nr. 102/2012 and subsequent modifications set the obligation for apartment and multi-apartment buildings supplied by a common central heating source or by a district heating/cooling network, to install, by December the 31st 2016, sub-metering systems to allow a fair cost allocation through the tenants. In Italy the obligation has been recently extended to June, the 30th, 2017. In several studies conducted in different EU Member States a very wide range of variability (8-40%) of the expected benefit of heat accounting systems has been found. Unfortunately, specific studies regarding the Italian territory and the Mediterranean climate conditions are still lacking. Nevertheless, due to the large number of buildings virtually subject to the obligation, the potential for energy savings in Italy could be among the highest in Europe. In the present study, after a brief analysis of energetic benefit of common heat accounting systems, the authors evaluate the potential impact of such systems on the energy consumption of the Italian residential building stock. To this end, the Italian residential building stock has been analyzed through both the ISTAT census 2011 and a recent statistical analysis performed by ENEA based on ISTAT data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
