together with different sensors and control strategies. (Figure 2) In addition to energy use, computer
screen visibility is being studied to determine the best shade properties and operating strategy. (Figure
2) Testing will be undertaken through mid-2004 to capture the full range of sun conditions.
Figure 2: Interior photos of newly constructed testbed for New York Times building. At left, view toward
the west facade, with two different shade systems partially deployed. At right, an instrumentation cluster
at a workstation, including illuminance and luminance mapping sensors, and a webcam.
A series of RADIANCE simulations of the space were prepared to explore design and operating issues
related to the shade systems and lighting controls. (Figure 3) Detailed optical properties of all interior
furnishings were measured. RADIANCE images will allow extension of measured results to other
orientations and to account for other site conditions such as adjacent buildings.
Here’s what’s next.
