Abstract— For the past years, the University of Santo Tomas had an increasing energy consumption. Through an energy audit, possible energy conservation opportunities and programs may help decrease the energy expenses of the university. After calculating the 4-Academic Year Monthly Average of the buildings in the university, it was shown that instructional buildings contributed the largest. Among these instructional buildings is Beato Angelico Building, the university’s lone building for architecture, fine arts and design programs, which was chosen as the subject of the study. An ASHRAE Level 2 energy audit was used in the energy auditing process and showed that HVAC contributes 68.50% of total energy consumption while plug equipment, and lighting contribute 23.30%, and 8.21% respectively. The identified energy activity centers which contributed 80% to the total power consumption of the building were classrooms, art laboratories, computer laboratories, and offices. Energy conservation opportunities present in these areas were known after careful analysis. Through the energy audit, various energy policies, strategies and recommendations had been proposed, which contributed to an energy conservation of 19.21% that resulted to lesser energy expenses for the university.
