This paper analyses the current state of the energy consumption in public housing built during the last few years in the province of Tierra del Fuego. A synthesis of the results obtained from the analysis of various housing with typological and constructive differences is presented; as well as a comparison with dwellings in other localities of the country with similar characteristics. Different typologies are compared,grouping them under the same heating degreeday for their comparison and there arises as a hypothesis that the housing in the south extreme of the Patagonia has a high energy consumption that exceeds the variables of the construction and the project. The results are systematized in order to serve as a useful precedent for future improvements. The feasibility of their implementation and the contribution to investigation and development in the sector are discussed as well.
