Abstract
New researches about housing consider sustainability issue to get a general improvement of people’s quality life. Recent laws on energy requirement for buildings, the application of EU Directive 2002/91/CE, and the consequent fall-out on building activities are coming together to create an awareness of the added economic value of a building’s improved energy effectiveness; this driven effect will tend to act as a lever to trigger more appropriate responses in terms of setting as well as structures, involving the evaluation of energy consumption, the level of comfort of the inhabitants, the production of harmful substances and rubbish, and the rationalisation of the use of water resources. All this however is meeting a certain resistance on the production side, in particular with the baggage of skills and capabilities of builders and planners who often approach residential building, drawing on an inheritance of well-established technological and morphological solutions, thus rendering banal the technical offer of the market and standardising the panorama of the expanding city. The current legal situation values envelope solutions in terms of thermal conduction, without consider characteristics of materials that constitute it. The market offers a lot of solutions for insulating materials, different for typology, performances, possibility of use and production system. For this reason, it’s necessary to promote an evaluation of the general characteristics of the products. It’s necessary to value the satisfaction of inside comfort’s levels of the building reported to thermal and acoustic isolation’s performances; and also it’s important to consider the possibility to use the material in different way according to building’s orientation and climatic area. Finally, it is necessary to value how much the production and the use of a material can produce consequences on the surrounding environment. The PEI value of the material, consequential from the LCA, offers information about the consumption of primary energy and available resources utilized to produce and use the material. Materials and technical solutions evaluated according to these criteria may contribute to improve the energy efficiency of the building system and, at the same time, can be evaluated, also observing the consequences which the use of a solution may have on the environment and the ecosystem, beyond a simple evaluation of their use in thermal insulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
