In order for the Phipps Center for Sustainable Landscapes in Pittsburgh to generate its own energy and renewable resources, it will include Sungate 500 Starphire glass and Solarban 60 Starphire glass by PPG Industries. Sungate 500 Starphire glass will be installed above the sunshade and light shelves, while Solarban 60 Starphire glass will be used below. When combined with Starphire glass in the specified triple-pane IGU, Sungate 500 glass has visible light transmittance (VLT) of 63% and a solar heat gain coefficient (SHGC) of 0.51, which yields a light-to-solar gain (LSG) ratio of 1.24. Solarban 60 Starphire glass in the same configuration generates an LSG ratio of 1.90 based on VLT of 61% and a SHGC of 0.32. Winter nighttime U-values for both configurations are less than 0.20.
