Roof Materials

Eighty-two Daylighting Systems were installed in the renovated 16,533-square-foot building, formerly an abandoned retail boutique at the corner of 44th Street and Van Buren in Phoenix.

“The use of the Daylighting Systems was an integral part of our sustainability and lighting energy savings plans for the renovated space,” says Dave Elrod, regional manager of DPR Construction, Phoenix. “The products are a cost-efficient solution to provide lighting since they nearly eliminate the need for artificial daytime lighting.”

In addition, the roof is composed of foam with an R-25 insulation value (approximately 4-inches thick) over plywood sheathing.

Daylighting systems manufacturer: Solatube International Inc.
Foam roofing manufacturer: Quik-Shield from SWD Urethane

Roof Report

DPR Construction is a national technical builder specializing in highly complex and sustainable projects. In less than 10 months, the design-build team researched, designed, permit-ted, and built a highly efficient and modern workplace with numerous innovative sustainability features.

In addition to natural daylighting, the office features an 87-foot zinc-clad solar chimney, which releases hot air from the building while drawing cooler air in; shower towers that act as evaporative coolers to regulate building temperatures; 87 operable windows designed to open and close automatically (based on indoor/outdoor temperatures); and two “vampire” shut-off switches to keep electrical devices (radios, cell-phone chargers, microwaves) from using plug energy when no one is in the office.

Access to the building was limited during construction. Spray foam roofing, which took about seven days to complete, had to be done in small quadrants because of the tight schedule as work was progressing in the other sections. The roofing workers were challenged by the barrel-shaped roof, which created footing difficulties, and the many penetrations that had to be flashed, including all PV support legs, Solatubes, skylights and HVAC penetrations. Work was completed in the middle of winter, so additional protections and efficiencies were required.

The circa-1972 building has been officially certified as a Net-Zero Energy Building by the Seattle-based International Living Future Institute through its Living Building Challenge program. It also has received LEED-NC Platinum certification from the U.S. Green Building Council, Washington, D.C.

Steelscape Now Offers Graffiti-resistant Coatings from PPG

PPG Industries’ building products group announced Steelscape is now offering metallic-coated and pre-painted steel with DURANAR GR (graffiti-resistant) and CORAFLON GR coatings.

Duranar GR and Coraflon GR three-coat systems feature a primer and color coat topped with a graffiti-resistant clearcoat that can be cleaned with DURAPREP Prep 400 graffiti remover by PPG. If the Steelscape steel is spray-painted, graffiti can be eliminated by applying the graffiti remover directly to the stain, allowing it to sit for 10 to 60 seconds, then wiping it with a clean cloth or scrubbing it with a nylon brush. Most stains can be removed in 10 minutes or less.

When applied on either Duranar GR or Coraflon GR clear coatings, Duraprep Prep 400 field-applied graffiti remover also can eradicate paint overspray, pen and marker ink, lipstick, scuff marks, tape residue, bugs, tar and many other substances that mar the appearance of steel building panels.

Duranar GR coatings are available in a variety of low and medium glosses; Coraflon GR coatings are for high-gloss finishes.
