Development of an energy audit working procedure for an academic university office building in the philippines

The Philippine commercial building sector accounts for roughly 10% of the total electricity power consumption. For this research, an energy audit was conducted in an academic office building of a Philippine university. The study focused on eight representative offices within the building to serve as pilot facilities for this research. The study evaluated the performance of existing lighting fixtures to attain the minimum acceptable standard of 300 lux for offices as well as the performance of existing air conditioning units to achieve a recommended room temperature of 24 Celsius. From the results, it is evident that the air conditioning unit makes up majority of energy use in almost all offices, with an average of 63% of total power consumption, followed by lights with 23% and plug-in loads with 14%. For maximum lux values with minimal energy consumption, the use of LED lights is recommended while for temperature, the use of inverter technology is encouraged for long term energy savings.
