This paper presents the design and performance analysis of a programmable power controller (PPC) to reduce electrical energy consumption of heating, ventilating, air-conditioning (HVAC) devices used in office buildings. This PPC operates based on the pre-programmed turning-on and turning-off HVAC devices such as air conditioners, fans, etc. including lightings in a building automatically with the use of a computer program. Programming can be done either based on pre-scheduled functioning of the devices considering the users behaviour or using feedback sensors of the room conditions. It concludes that in general there is still common to find the negligence of occupants/users to turn off the HVAC equipments of the building under consideration, being potential as priorities of energy management and conservation measures. It shows also that the use of PPC is prospective in energy management and conservation efforts, resulting in a prospective reduction of up to 20% - 30% of electrical energy consumption of the building under study. © 2006-2015 Asian Research Publishing Network (ARPN).
