After the green light to European directive on so-called green homes, the question arises spontaneously: where is Italy at? How many houses are in compliance with the new provisions and how many will have to catch up with the required requirements within the required time? The objective of the directive approved by Ecofin last April 12 is in fact 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 Let’s see what the situation is in the Italian regions.
The national ranking, drawn up thanks to data collected by Information System on Energy Performance Certificates (SIAPE), takes into consideration variables such as green APEs, which must contain the energy classification of properties, CO emissions2 and the average renewable energy consumption indices (EPgl,ren) and non-renewable (EPgl,nren).
Based on these data, what emerges is a situation in which a clear minority of Italian homes have the energy performance certificate. Among the regions that have the most, it is the Valle d’Aosta to win the title of first Italian region 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%) – higher than the Italian average of 14.3% of certificates – and for the average renewable energy consumption index (40.8 kWh/m2 year).
The silver medal, however, goes to Trentino Alto Adige with a score of 7.9. In third place we find Lombardy – second in terms of number of energy performance certificates (20.7%) – e 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 Marche (6,4) e 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 then continues with Piedmont (5,4) e 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, is Calabria (4,4), theEmilia 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.
