Cities are home to half of the world's population. By 2050, 70% of people would live in different cities, based on UN reports. Obviously, the population growth has made serious environmental consequences such as climate change and GHG emissions. More specifically, one of the main actors regarding energy consumption is construction sector or more specifically residential buildings where energy is needed for various activities, which, the main contributors of consumption are space heating & domestic hot water. Therefore, understanding of buildings characteristics & thermal energy profile in existing situation, and predicting it for future has a considerable importance. Therefore, applying energy consumption analysis should be at city scale instead of a single building The selected case study is the metropolitan area of gran Mendoza located in Argentina.
