摘要

Demand-responsive buildings utilize control mechanisms tonreduce their electricity use during periods of high grid-wide demand,nprimarily to aid utilities in maintaining grid stability. Dimming lightingnis proposed as one such demand response mechanism, and severalnlaboratory studies have explored the speed and extent of dimming thatnis either noticeable or acceptable to occupants. We conducted a fieldnstudy to examine whether these laboratory findings could be applied innreal buildings with commercial lighting control systems. The study,nconducted during summer months, included an open-plan office withn330 dimmable luminaires, and a college campus with 2300 dimmablenluminaires across several buildings. In the office building we conductedntwo afternoon demand response trials, which dimmed lights by up ton35 percent over 15–30 minutes. The power reduction achieved was 5.2nkW (23 percent), and 5.3 kW (24 percent), respectively. At the campusnsite we conducted three afternoon demand response trials, whichndimmed lights by up to 40 percent over 1–30 minutes. The powernreduction achieved was 15.2 kW (18 percent), 7.7 kW (14 percent), andn11.3 kW (15 percent), respectively. There were no lighting-relatedncomplaints to facilities management throughout the afternoons of thentrials. Based on prior laboratory studies and this field study wensuggest guidelines for dimming lighting as a demand responsenstrategy.
