The Protocol ITACA is a tool for the certification of the level of environmental sustainability of buildings of different uses. It is ‘promoted by the Italian Regions and managed by a specific committee with representatives of the regions and participation of  association iiSBE Italy and ITC-CNR. The protocol is based on SBMethod, chosen in 2002 as a reference by the Italian regions.

The Protocol ITACA system is configured as a federation of regional assessment protocols characterized by a methodology and common scientific and technical requirements. The idea is to share a common standard but allow a variation at a local level.
The Protocol ITACA, thanks to the characteristics of SBMethod, allows a contextualization to territorial peculiarities of the regions, while maintaining the same structure, scoring system and weighing. This quality is especially important for Italy as characterized by climatic profiles and different construction practices.
Several regions have adopted the Protocol ITACA as a support for their policies in the area. There are regional versions of the protocol:
Piemonet Region
Liguria Region
Marche Region
Toscana Region
Lazio Region
Puglia Region

ITACA versions derived from the Protocol have been developed in the Umbria Region (VSA), Friuli (VEA) and Veneto (Biover).

Now the protocol that is going to become “Prassi UNI and will be recognized nationally as a practice for the assessment of energy and environmental performance of buildings.

In Friuli Venezia Giulia Protocol VEA, which is derived from the Protocol ITACA,  is mandatory for residential buildings and offices in the case of new construction, expansion and renovation construction.
