Daylighting design for the Pacific Museum of Flight: Energy impacts

摘要: Abstract The daylighting performance of the Pacific Museum Flight in Seathle, WA, has been analyzed using DOE-2.1C building energy simulation program. main exhibit areas this museum are enclosed on three sides by glass walls and 4500-m2 roof is completely glazed. Because large areas, a detailed thermal was carried out during its design phase order to select glazing parameters that would avoid excessive summer solar heat gain, reduce winter loss and, at same time, provide enough natural light significantly electric lighting loads. Glazing choices considered included conventional glass, mirror, with low-emissivity coating. On/off, stepped continuous dimming control systems were analyzed. Daylighting found be very effective reducing annual load, peak electrical demand, overall consumption.
