Il controllo della sostenibilità ambientale: i regolamenti 3E per l’efficienza energetica degli edifici

The issues of sustainability and energy efficiency in buildings are slowly entering the construction sector also in Italy, where they have been lagging be- hind if compared to other European countries. The introduction of national and local regulations implemented Directive 2002/91/CE on energy efficiency of buildings, with specific differences due to the local character of the legislation. In this field, Regione Lombardia (Lombardy) is one of the most active re- gions in Italy, being the second one (after the province of Bolzano) to define the rules for energy certification. A law that is specific to Lombardia allows cities and towns to increase building ratios if the building has characteristics of sus- tainability behind standard requirements. The performance requirements allow- ing the increase in building ratios need to be defined by the local authorities, who thanks to these incentives are able to drive the “business as usual” con- struction market towards better quality buildings. This paper discusses the experience of the author, together with a variable research team, in drafting local energy efficiency and sustainability standards. Different works will be presented, ranging from regulations for small towns to integrations to the building code of Milan, each with its own specific issues to be tackled.
