Abstract
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.
Highlights
In September 2008, the authoritative international programme Global Carbon Project published the results of the Carbon Budget 2007 [2], according to which the annual increase in CO2 in the chemical composition of the atmosphere for 2007 was equal to 2.2 ppmv compared to 1.8 ppmv in 2006, while in the last twenty years it was equal to 1.5 ppmv
This increase brought the concentration of carbon dioxide in the atmosphere to 383 ppmv in 2007; i.e., 37% above that existing at the beginning of the Industrial Revolution
The European Commission [5] is directing operators in the sector towards a wide range of technological solutions that can be used to drastically reduce the energy consumed by real estate assets
Summary
The fourth report of the Intergovernmental Panel for Climate Change (IPCC, 2007) [1] highlighted the main responsibility of human action in the emission of greenhouse gases responsible for climate change: “The global increase in the concentration of carbon dioxide is mainly due to the use of fossil fuels and changes in land use, while increases in methane and nitrous oxide are mainly due to agriculture.” In September 2008, the authoritative international programme Global Carbon Project published the results of the Carbon Budget 2007 [2], according to which the annual increase in CO2 in the chemical composition of the atmosphere for 2007 was equal to 2.2 ppmv (parts per million volume) compared to 1.8 ppmv in 2006, while in the last twenty years it was equal to 1.5 ppmv. The study by Fantozzi F. et al [15] shows that, in Italy, there are many attempts to apply technical-economic evaluations on energy saving strategies In this regard, there are experiments relating to optimal conditions of comfort in relation to costs for school buildings [16]. The method allows identification of, among a series of projects, the one most compatible with the environmental parameters of the Italian CAM (Criteri Ambientali Minimi), as well as the costs necessary to reach the minimum thresholds, and, after exceeding them, by obtaining the rewarding scores In this way, it is possible to direct the economic investment choices of the operators in the sector [21]. Evaluation, among various project solutions, of the most suitable one for the choice of the financial investment
