This paper demonstrates the results of research concerning eco-efficiency at the University of Passo Fundo – Southern Brazil. Its objective is to identify the factors that affect energy consumption in buildings of Higher Education Institutions and to elaborate a methodology that can facilitate the evaluation of the degree of influence of each one with the aim of defining criteria in the following areas: improve the use of natural resources in the building stock and formulate guidelines for the inclusion of objectives which include environmental, energy and thermal comfort in the planning of new installations. For the energy performance analysis, the concepts of Energy Audit were adopted and applied to two buildings of the Engineering and Architecture School, representing the different typologies of UPF´s Campus I. The static data (general characteristics of the buildings and indoor spaces, systems and installations), was analysed. The dynamic data was obtained by checking energy consumption for different uses; the indoor thermal performance and PMV index was also analysed. The real conditions of the buildings were then compared with the results of energy performance simulated by the software DesignBuilder. The results allow for a diagnosis of the building stock conditions of UPF, with the identification of positive and negative points. A proposal of an operative instrument for thermal and energy performance improvement of the existing buildings plus standards of reference for new eco-efficient buildings will be developed.
