Valle d’Aosta is the first region in Italy for green homes, thanks to a score of 8.4 out of 10: it is first for the high number of APE energy performance certificates (22.1%) – above average Italian of 14.3% of certificates – and for the average renewable energy consumption index (40.8 kWh/m2 year).
The national ranking in fact takes into consideration variables such as green APEs, which, as the Acea Energia guide reminds us, must contain the energy classification of properties, CO emissions2 and the average renewable energy consumption indices (EPgl,ren) and non-renewable (EPgl,nren).
The topic is hot, the Ecofin vote was held on April 12th: the Council of European Ministers of Economy and Finance gave the green light to the directive on the energy performance of buildings.
The objective is to significantly reduce energy consumption and polluting gas emissions attributable to houses and buildings by 2035, with the ultimate aim of creating zero-emission properties by 2050.
According to the data collected by the Information System on Energy Performance Certificates (SIAPE), the silver medal, however, goes to Trentino-Alto Adige with a score of 7.9. In third place we find Lombardy – second for the number of energy performance certificates (20.7%) – and Basilicata – fourth for APE (18.6%) and for the average use of renewable energy (25.9 kWh/m2 year) –, both of which score a 7.6 out of 10.
Off the podium are Marche (6.4) and Friuli Venezia-Giulia (6), followed equally by Abruzzo (5.8) – characterized by low CO emissions2 and by a reduced use of non-renewable energy – and Veneto (5.8) – penalized by a low use of renewable energy.
The ranking of Green Houses then continues with Piedmont (5.4) and Tuscany (5). In ninth place, both with a score of 4.9, Puglia and Umbria: the first, thanks to the release of low quantities of CO2; the second, due to the high average consumption of renewable energy. Sicily closes the top 10 (4.7), first for reduced carbon dioxide emissions.
Among the less virtuous regions, with room for improvement, are Calabria (4.4), Emilia-Romagna (4.1) – first for use of non-renewable energy with 240.7 kWh/m2 year, higher than the Italian annual average of 203.7 kWh/m2 –, Molise (3.8) and Lazio (3.1), which are affected by an extremely small number of green APEs issued.
