ABSTRACT:  The performance of a building as well as the sustainability and efficiency depend on Architectural and construction factors. Considering the importance of quality of life in a building that people spend sometimes most of their time, the analysis of such elements is essential. Therefore, the research “Assessment and diagnosis of eco-efficiency on Universidad e de Passo Fundo” make de evaluation about thermal and energy efficiency with building stock of the University campus. The methodology used in this work is Energy Audit, which make a relationship of the use and occupation with several types of energy. Therefore, it can be classified using two process: static data (building constructive features, interior spaces and facilities) and dynamic data, considering time modifications such as profile use, environmental variables and energy consumption. The V2 building, part of the Engineering and Architecture Faculty (FEAR), has been choose due to the different typology between other buildings inside the campus, for instance materials and construction techniques used since 2015. The installation of temperature and humidity equipment’s allowed the analysis of internal environmental conditions, as a result, this data allow the analysis of building envelope, comparing it with the labelling energy efficiency in Brazil – RTQ-C, by the prescriptive method. As a result, the labelling shows that the building envelope is not satisfactory in order to achieve an ideal efficiency. The Brazilian rules stipulates minimum requirements of buildings performance besides the implementation of new guidelines according to positive applications and criteria for the buildings of Campus I.
