A major component of DPR Phoenix’s netzero success has been the office’s ability to reduce its electrical lighting load by an amazing 90%. First, the team decided to locate all the glazing on the east and north façades.
Cutting into the existing exterior masonry walls, eight openings were created and utilized to install 87 operable windows, an entrance and two rollup doors to both provide daylighting and connection to outside patios along the east and north sides. The window units incorporate insulated, low-E glazing, horizontal shading devices and vertical green screen elements to minimize direct solar heat gain.
However, the biggest component of the daylighting are the Solatubes, which carry natural daylight from their rooftop skylights through highly reflective pipes and finally into ceiling fixtures, which evenly distribute 100% natural light throughout the open office area, conference rooms, bathrooms and marketing areas.
