Multiple solar control low-emissivity (low-e) Vitro Glass products were used in the construction of 4545 Roosevelt, a six-level addition to University Center, a mixed-use complex in Seattle’s University District.

Built on the site of a former auto dealership and designed by NBBJ Architects, 4545 Roosevelt features complex insulating glass units (IGUs) made up of ���DZ�����������® 70XL, Solarban 67, Solarban 60 and ���DZ����������ܱ�® glasses by Vitro Architectural Glass.

The cladding and window systems combine multiple color profiles inspired by the Ferrari brand of luxury vehicles. The accent-colored spandrel panels, made up of a clear substrate over a clear IGU by Vitro Glass, are finished in Harmony Gray, an OPACI-COAT-300® water-based silicone coating by ICD High Performance Coatings, a Vitro Glass partner.

Hartung Glass Industries of Seattle, a member of the Vitro Certified™ Network, fabricated the IGUs.

With center-of-glass visible light transmittance (VLT) of 64 percent and a solar heat gain coefficient (SHGC) of 0.27 in a standard 1-inch insulating glass unit (IGU), Solarban70XL glass is one of the industry’s highest performing solar control low-e glasses. When paired with Solarban 67 glass in an IGU, Solarblue tinted glass offers SHGCs that range from 0.19 to 0.34 and visible light transmittance (VLT) of up to 42 percent. Solarban 60 glass blocks 62 percent of total solar energy while allowing 70 percent of visible light to pass through.

The 55,000-square-foot structure, which was built on top of an existing parking structure that is part of University Center, contains two levels of parking and four levels of Class A office space.

Given the anticipated growth in the technology sector, 4545 Roosevelt is viewed as a “catalyst” for the area, according to the developer, Blume Co. Real Estate.

Home to the main campus of the , the University District is a vibrant mix of residential, commercial and institutional communities.
