Abstract:
Building of Pontianak State Polytechnic has a special characteristic in the intensity of electric energy consumption. This is
one of the typical of vocational education institutions, due to the need for the implementation of practicum in the field of
engineering. Various ways to do conserving electrical energy such as by reducing electricity consumption in the air system
and lighting system.This study explains three main factors that will affect the use of electrical energy for lamps and Air
Conditioning (AC), those are natural lighting, room and outdoor space.The results obtained in the form of hypothesis that
there is a very significant relationship between the intensity of light, space and outdoor temperature in determining energy
efficiency priority to a room and the percentage of dynamic efficiency for each room based on predetermined criteria.
