Building energy performance has a key role in the international energy scenario. Labelling procedures have been developed in several countries for certifying the environmental sustainability of buildings, aiming at reducing energy consumptions and environmental impacts. In this study, the impacts of the insulating materials on the energy and environmental performance of a residential building have been analysed.
While the day in which nearly zero energy buildings is quickly approaching, their construction cost remains higher than minimum requirements' ones, in this framework operates CoNZEBs (Solution sets for the cost reduction of new Nearly Zero-Energy Buildings) Project, funded EU Horizon 2020. This paper explores a critical point identified by the project: potential cost reductions in the design and construction process.
Energy sustainability of new service buildings should considers the use of envelope materials able to minimize thermal dispersions avoiding at the same time environmental and landscaping impacts specially in the small islands of Mediterranean sea generally characterized by high environmental and landscaping values. In this context, the paper provides an analysis of local materials for the design of low-energy service buildings in touristic islands, according with the concept of re-use.
