This work presents the results from the analysis of the behavior of demand and energy consumption in the Campus of the Universidade Federal de Santa Maria to contribute to the adoption of strategic plans for demand side management. Presented are the basic concepts of electrical quantities, the definition of demand, as well as its available control and management techniques. The advantages of the demand side management option are highlighted. Two sets of load curves were collected : the load shapes of the campus as a whole, obtained from two years of demand records by the local electricity provider's energy meter; and the individual load curves of various buildings throughout the campus, obtained from measurements made with a multi-quantities electrical meter. Presented are the methods of obtaining their curves and highlighted the influence of temperature, business hours, school calendar and days of the week on them. Finally, a comparison is made between the whole university curve, with the individual load shapes. The set of information obtained forms the basics for demand side management on the campus, in near future. The results indicated that public educations buildings have peculiarities that should be taken into account when adopting measures to reduce consumption and load management. Such measures must take into account the presence of loads of different nature (purely academic through industrial, commercial and residential) and with different hours of use in comparison to similar off-campus loads.
