For the non-residential sector, on the other hand, the increase in APEs in the less efficient classes (+ 3.5%), already recorded last year, is confirmed, even if the sector boasts a greater share of certificates in the best and intermediate energy classes (approximately 55% against 40% of the residential).
It is the picture that emerges from the Annual report on the Energy Certification of Buildings made by ENEA and the Italian Thermotechnical Committee (CTI).
Of the approximately 950,000 APEs analyzed, three quarters concern buildings built before 1991 and almost 6% of the more recent ones (2016-2020); about 85% of the certificates are related to changes of ownership and leases, just over 3% to new buildings, almost 4% to energy redevelopments and less than 2.5% to major renovations.
Among the most important innovations of the Report, now in its second edition, the significant increase in the database used for detailed analyzes, which almost doubled compared to 2019 (approximately 950 thousand APE against 540 thousand in 2019); an increase that made it possible to carry out more in-depth surveys of greater statistical and qualitative value to monitor the evolution of the energy performance of the national building stock.
Furthermore, with the connection of Emilia-Romagna and Molise in the course of 2020, the number of Regions that feed the SIAPE, managed by ENEA, expanded. Three other regions (Valle d’Aosta, Marche and Sicily) have begun the transfer of data in the course of 2021. In 2020 ENEA activated the SIAPE portal which allows citizens, professionals, companies and public administrations to analyze the certificates contained in the national system and monitor the state of the art of energy requalification of the national building stock.
“The results of the 2021 Report show that by strengthening collaboration with Regions and Autonomous Provinces it is possible to undertake new paths to increase the effectiveness and potential of the EPAs”, comments the President of ENEA Gilberto Dialuce. “The progress in the collection and processing of data favors the strengthening of SIAPE, the Information System on Energy Performance Certificates, which, gradually, will be able to represent the main source of data on the energy characteristics of buildings on the national territory. The results obtained – he adds – are very interesting in a context in which the updating of the methodology for the classification of buildings and harmonization at European level are very topical”.
“This edition highlights how the reference data has improved, the analysis of the same has been strengthened to provide more and more information on the interest of the market, the relationship with the Regions and Autonomous Provinces has been consolidated and how awareness has spread among operators about the availability of a tool that will be increasingly important for the real estate sector ”, underlines the President of the CTI, Cesare Boffa. “We are talking about a real manual – he adds – which explains how to read the information collected in the SIAPE in an aggregate way. An important job that will be able to improve thanks to our commitment and the collaboration of all the actors involved “.
