The Brazilian pioneer experience in energy efficiency management in public university campi is the Permanent Program in Efficient Energy Use of the University of São Paulo (PURe), running since 1997. Total built area of the university totalizes above 1 million square meters throughout more than 20 cities in the state of São Paulo, which results in a very complex energy use network comprising several different end uses. Interaction between actions and appliance purchases throughout our campi under the scope of PURe, for the sake of energy management in the University, is described along this paper. Energy bills and contracting, retrofits, experiences in usage of renewables, education and diffusion of information on energy efficiency and rational energy use are some among the described instruments, and accruing savings are shown.
