Smart envelope and climate context

Abstract

The construction sector today is characterized by demands for new qualities in the field of energy efficiency. This attention has taken on an even more incisive role with the European Directives 2010/31/UE and 2012/27/UE, which obliged Member States to implement actions for energy saving by paying more attention to the planning phase. The general goal of the research is to analyse the smart envelope by verifying the influence that the reference climate context has on the energy efficiency of buildings, making progress in the study of the principles of smart buildings linked to an integrated renewable energy system monitored in order to put it directly in communication with the final user. In fact, it is important not only the choice of materials, but also the right contextualization and their correct installation to provide more information for better control and more efficient energy management from the building level up to small urban areas, “matrioska effect”. The envelope thus becomes the protagonist par excellence for the correct management of energy flows both in and out.The energy efficiency of buildings, in fact, is mainly determined by the performance of the envelopes, the efficiency of the facilities, the use of renewable energy sources, the passive control systems of winter and summer comfort. Performance that depends on various factors, such as shape, orientation, transparent surfaces, solar gains, ventilation, technological systems used, materials … This need to design in a “renovated” has changed the concept of technical construction elements developing increasingly smart components following the rules of automation, or more specifically those of automation and management of technologies through the use of domotic for existing interactions with the climate context of reference. Therefore the research aims to develop a methodology that provides more information on the energy performance of home automation systems.
