Energy containment: example of bio-climatic design methodologies

Analysis of energy consumption in Europe shows that the sector is the industry's most energy (40% of total) in Europe has established a new legislative framework in order to reduce consumption: Directive 2002/91 EC. With the introduction of energy certification Directive is one of the objectives for the energy efficiency of buildings and generate a new offer aimed at building models less dissipative. The case study presented examines the restructuring of a building in Pozzuoli (Naples) on the basis of the principles of bioclimatic engineering through the use of spreadsheet Casa Clima. Casa Clima, was developed by the Province of Bolzano (IT), in 2002 established a minimum standard to be observed (C>FEAP =70 kWh/m2a), its the first Italian example of mandatory energy certification. The authors present a design example of a planned maintenance using the methods of bioclimatic engineering to obtain a passive response in terms of energy.
