COMO OS EDIFÍCIOS DE ENERGIA ZERO RESPONDERÃO ÀSMUDANÇAS CLIMÁTICAS? -UMA REVISÃO

Abstract

As a climate change mitigation measure, Zero Energy Buildings (ZEB) has been playing an important role in energy reduction in the built environment. Thus, this work aims to review, identify and classify the different design measures applied to zero energy buildings, facing the challenges of climate change. The methodological procedure consists of searches using strings in a scientific database and, subsequently, the searches were screened, resulting in 138 articles from journals. The results show that the existing literature on this topic reports that climate change is significantly influencing the internal temperatures of buildings and that the ZEB will be warmer in periods such as summer, requiring the implementation of passive bioclimatic strategies. Thus, numerous studies applied bioclimatic design strategies, such as natural ventilation and shading, as well as energy efficiency measures, such as thermal insulation in external walls, roofs, and double glazing in buildings. However, it was found that under the new future climate conditions, zero energy buildings present conditions of thermal discomfort in their interior, as well as not supplying the future energy demand, requiring the implementation of new mitigating measures. It is concluded that the ZEB is an important instrument for the mitigation of climate change, however, there is a need to investigate these buildings under future climatic conditions, that is, using recent climatic files and/or in climate prospecting, so that buildings can respond more resiliently to future climate change.
