Kittitas County Courthouse Energy Audit <br />controls. Larger common areas and larger offices have multiple switches to control the number <br />of fixtures in the spaces to be turned on. <br />In many areas of the building receiving significant natural lighting, the overhead lights are used <br />sparingly, indicating that occupants would likely benefit from dimmable light fixtures and <br />daylight -responsive lighting controls. <br />Exterior light fixtures include LED wall packs, LED surface -mounted under canopy lights, <br />recessed single -bulb cans, wall mounted sconces, three -head lampposts, and bollard lights (see <br />Figure 3-13 through Figure 3-18). Most exterior light fixtures are LED -type or use LED bulbs. <br />Many of the exterior light fixtures show signs of age and weather -related wear and should be <br />considered for replacement as practical. <br />Exterior light fixtures are controlled by time clock (see Figure 3-19), with some fixtures <br />additionally controlled by fixture -mounted photocells. The time clocks are set to operate the <br />exterior lighting from 4 pm to 8 am. Time clocks are on a fixed daily schedule and cannot run <br />differently on weekends or adjust for seasonal daylight availability. <br />Figure 3-9 Office/Common Area Fluorescent Light Fixtures <br />Project Number 22-084 12 <br />October 28, 2025 <br />
