Retrofitting and energy control of an Academic Building

This paper presents brief overview of a program of retrofitting and control of Academic Buildings. The proposed system has the main objective of reduce the energy consumption of lighting systems and air conditioners (A/C), two of the most common loads found in office and/or classroom buildings. The proposed BACS implements a two network technologies, Ethernet to connect a central control unit with each building, and a ZigBee mesh wireless network towards the building interior. Buildings energy savings are obtained by combining a turn-on/turn-off control of lamps and A/C, temperature operation adjust of 26°–27°C and retrofitting of conventional lamps with LED lamps. The system has a graphic Human-Machine-Interface that allows a fast system configuration.
