Abstract
A growing awareness toward sustainability is pushing for new methods to promote the reduction of greenhouse gases. Considering the world's energy consumption, one finds that a non negligible part of this consumption is due to the building sector. It is thus of importance to promote the use of renewable energies in buildings and to increase their energy performance. Energy and environmental certification of buildings enables the assessment of their energy and environmental sustainability. With this instrument it is possible to classify the building's quality, with particular attention to indoor environment sustainability, resource consumption, the quality of the services and their administration during the building's lifetime. The case study is a residential building located in Città di Castello (Umbria, Italy). SB100 methodology, ITACA Protocol and the evaluation forms based on Green Building Challenge have been used. The SB100 methodology considers the compilation of 100 forms regarding building interventions so it is possible to arrive at a high level of environmental sustainability and an efficient use of energy resources. The interventions are divided in three macroareas: ecology, society and economy. ITACA Protocol is based on seven evaluation areas: outdoor environment quality, resource consumption, environmental loads, indoor environment quality, service quality, management quality, and transports. The Green Building Challenge methodology evaluates the level of environmental sustainability of a building and it measures its performance with 3 standards divided in five areas: energy and resource consumption, environmental loads, indoor environment quality, service quality, context quality. The application of each procedure to the building in case allowed the comparison of the three methods used for the energy and environmental certification, which have been elaborated following different evaluation standards for the final score; It is therefore possible to point out the different aspects of energetic and environmental problems. Some differences nonetheless exist between the three methodologies: the Green Building Challenge methodology is based on LCA (Life Cycle Assessment), whereas SB100 and ITACA Protocol focus particularly on traditional energetic-environmental aspects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
