In recent decades, the international scientific debate has focused on maximizing the energy performance of the building organization during the operational phase. However, the energy performance is only partially in line with the strategic environmental objectives defined by the European Commission which, with Communication 2003/302, also defined the guidelines for the drafting of the National Action Plans on Green Public Procurement (NAP GPP). Law no. 296 of 27 December 2006 provided for “... the implementation and monitoring of an Action Plan for the environmental sustainability of public administration consumption”, drawn up by the Ministry of the Environment and the Protection of Land and Sea. This work moves in the direction of identifying design strategies, relating to construction and urban restructuring, compatible with the criteria of energy and environmental sustainability provided for in the New Code of Public Procurement (Legislative Decree 50/2016), in accordance with the directives of the European Community. The parameters that define the methodological articulation (choice of case studies, scope of reference of stakeholders, etc.) orient the use of the results towards similar cases, i.e. design of urban districts located in regions with a Mediterranean climate.
