Development of a Rotatable Outdoor Testbed and the Testing of an Integrated Auto-dimming Lighting and Automated Blind System in the Tropics
To drive the research and development of energy-efficient building technologies in the tropics,an advanced rotatable testbed,BCA SkyLab,was developed in Singapore in collaboration with Lawrence Berkeley National Laboratory(LBNL).As worlds first high-rise rotatable testbed for the tropics,this facility is an outdoor testbed sitting atop a 7-storey building,with a rotatable platform that can simulate various orientations of building.The testbed allows testing and evaluation of performance of various technologies in the tropical urban environment,including lighting,air-conditioning,facades,shades and control systems.Performance in visual comfort and potential in deeper energy savings of an integrated auto-dimming lighting with automated blinds system was investigated in the SkyLab.This system was installed and tested together with a conventional baseline system in the two cells in the SkyLab.This integrated system uses auto-dimming control based on outdoor illuminance level through the Digitally Addressable Lighting Interface(DALI),and the automated blinds incorporates a two-section daylight-redirecting design to introduce maximum daylight while minimising Daylight Glare Probability(DGP).The system performance of energy savings and visual comfort were investigated with an innovative control algorithm developed in-house.It was found that the automated blinds effectively eliminated glare discomfort,and with the automated blinds working in conjunction with the auto-dimming,up to 74%of lighting energy savings is achievable without compromising the illuminance level at the working plane.
