The construction sector is one of the main contributors to climate change. According to the International Energy Agency, it is responsible for 40% of energy consumption worldwide and for 36% of its CO2 emissions. Furthermore, according to the European Commission, 70% of buildings in Europe are energy inefficient, mainly since buildings employ constructive solutions that are obsolete or poorly maintained. The eco-efficient rehabilitation of buildings is essential in the fight against climate change. The purpose of this work is to improve the façade considering the energy efficiency and the life cycle analysis of the constructive solutions. The proposed solution considers circular economy criteria and is composed of materials with a high recyclability rate. A methodology is proposed for the evaluation of the direct and indirect CO2 emissions, which combines energy simulation and environmental assessment by employing Building Information Modelling. A building in the south of Spain is studied. A comparison is made between the energy behaviour of the building in its original state and of that with an improved ventilated façade. Other types of representative rehabilitation solutions in Spain are also studied and compared. The embodied energy and CO2 emissions of the materials are significantly reduced to one third or less with respect to other traditional solutions. |
