Buildings are among the largest consumers of energy and CO2 emissions in the world. In this scenario, the high energy consumption of university campuses is particularly noteworthy due to their diverse uses, large number of users, and size. Therefore, it is extremely important to improve their energy efficiency. In this context, the present study aimed to identify and classify building typologies on the Darcy Ribeiro campus of the University of Brasília - UnB, with greater potential for energy optimization through the adoption of passive strategies. This work is part of the research project "Scenarios and proposals for energy efficiency in buildings and net zero energy campus", which aims to deepen the principles of net zero energy buildings and potentially extrapolate the results to the scale of the campus (district). As a methodology, buildings were identified using georeferenced data, categorized according to their primary use, and analyzed using the Morphological Diagram. This enabled the identification of typologies with the greatest potential for passive strategies implementation in terms of environmental comfort and energy efficiency. Subsequently, the selected buildings will serve as the object of study for the research project, with the objective of extending the principles of net zero energy building and applying them to convert the existing buildings on the Darcy Ribeiro campus into a net zero energy district.
