Development of an Experimental Model of BACnet-based Lighting Control System

Lighting control system provides various benefits in building management such as operational convenience, energy saving and peak demand control. BACnet(building automation and control networks) is an international standard communication protocol for building automation and control networks. In this study, we developed an experimental model of BACnet-based daylighting and fluorescent lighting dimming control system. The experimental model consists of lighting control system and a mockup of indoor fluorescent lighting facility, which are interconnected using BACnet protocol. Using the experimental model, we evaluated the performance of BACnet-based lighting control system. Results from the experimental model show that the energy consumption for lighting can be reduced up to 40%.
