Efficiency and energetic performance on the rehabilitation of residential buildings

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Planet Earth has been suffering severe changes in result of the continuous growth of the population and human activities. The construction industry sector is one of the most responsible of the impacts resulting of the urban expansion and number of buildings. This fact has results on environment, whit effects of the emission levels of pollutants waste and high consumption of non-renewable natural resources. These actions contribute to the rise of the risk of extinction and future reduction of the availability of natural resources for human activities. In another hand, the lack of efficiency of the building sector is an important factor in energy consumption, since the population in its search for higher comfort levels promotes greater energy consumptions. Thus, it becomes essential to change not only society's behaviors of production and consumption, but also the quality of buildings. It is also important to slow down the pace of new buildings and start betting heavily in the rehabilitation of the existing, managing to provide the existing ones with new and better conditions of habitability and in a context of sustainability. Through this paper we built a model of intervention based on measures that can be implemented in the rehabilitation of buildings and that will lead in the end to the increasing of energy efficiency. It was possible to conclude that the measures concerning the increase of the thermal isolation of the building envelope are the ones that present the best results and that, among these, the increase in isolation of the roof is of special relevance.
