Buildings in USA ~ 75% of all electricity (US-EIA 2008) Electric Lighting in USA ~ 25% of total electricity in buildings (DOE 2006) ~ 19% of electricity in USA is used for lighting
Laboratory Environment Daylight Harvesting Lighting Energy Savings • 45-55 % potential lighting savings from three years worth of illumination data (Littlefair, 2001)
• 60% lighting savings for a dimming system with automated blinds (Roche, 2002) • 20-23% lighting savings with windows from one side (Lee and Selkowitz, 2006)
• 52-59% with windows on two sides (Lee and Selkowitz, 2006)
Field Study Daylight Harvesting Lighting Energy Savings • <0% to 156% of predicted savings
• (Pigg et al. 1996; Jennings et al. 1999; Reinhart & Voss 2003; Moore et al. 2003; McHugh et al. 2004; Heschong et al. 2005; Hackel & Schuetter 2013; Galasiu et al. 2007; Fernandes et al. 2014)
• Savings from Toplit spaces more predictable than sidelit • (Heschong et al. 2005; McHugh et al. 2004)
• Recent studies show improvement • (Acker & Van Den Wymelenberg 2010; Fernandes et al. 2014)
• but!.problems persist (50% realization) • (Hackel & Schuetter 2013)

temperature extremes, ranging from –48 to 119°F, makes “mild” a
misnomer at times. Northwest weather and climate are dominated
by two main elements: (1) the vast Pacific Ocean to the west and (2)
the region’s mountain ranges that block and deflect low-level air.3
In the Pacific Northwest, as the jet stream pushes air from the west
inland to the east, clouds form on the western slopes of major mountains,
including the Cascade Range, and clearing occurs to the east. Long-term
weather data indicate that Seattle and Portland, both west of the Cascades,
are overcast nearly 230 days per year, but the inland cities of Spokane,
Washington, and Boise, Idaho, are overcast only 191 and 155 days per year
on average respectively. Overlaid on the contrasting character of areas west
and east of the Cascades is a distinct seasonal shift between cloudy winter
months to a dominantly clear sky period between July and October—this
pattern is most apparent west of the Cascades. The annual periodicity of
overcast and sun, caused by shifts in the jet stream over the Pacific Ocean,
combines with mild year-round ocean temperatures to amplify precipitation
in winter and inhibit it during the summer months.4
The physical and visual experiences of climate in the inland Pacific North-
west are different from those in the maritime coastal areas. Consequently,
each subregion’s daylight has its own characteristics. A common experience
east of the Cascades is the golden glow of low-angle late summer sun that
reaches across burned sagebrush-cloaked foothills and paints the ridges light
umber and the valleys dark umber during the early morning and late after-
noon and a vibrant gold at midday. In contrast, the forested coastal regions
of the maritime Northwest are defined largely by the inverted topography
of cloud cover. Here, mild temperatures predominate, and steely silver-gray
