Washington State University’s new Schweitzer Engineer Hall in Pullman, Washington, showcases how advanced glazing technology can balance architectural aesthetics, occupant comfort and energy performance. Designed by ZGF Architects in collaboration with The Miller Hull Partnership, the 65,000-square-foot academic building serves as a new gateway to the university’s engineering campus while blending seamlessly with the institution’s established architectural character.

At the heart of the façade is Solarban® 72 Acuity® glass by Vitro, selected for its combination of exceptional optical clarity, solar control and cost efficiency. According to the design team, the low-iron glass was chosen after evaluating multiple glazing options, offering a clear advantage by minimizing the green tint commonly associated with standard clear glass. The result is highly transparent façades that provide unobstructed views both into and out of the building.

The glazing delivers a Visible Light Transmittance (VLT) of 67% and a Solar Heat Gain Coefficient (SHGC) of 0.28, allowing abundant natural daylight while reducing unwanted solar heat gain to improve indoor comfort and energy efficiency. The glass was installed throughout the building’s four-sided structurally glazed curtain wall and punched window system, complementing dark grey metal panels, spandrel glass and the university’s signature red brick architecture.

Optical clarity was especially important for showcasing the building’s exposed structural steel and cross-laminated timber deck, reinforcing the project’s engineering-focused identity. Large glazed areas highlight active collaboration spaces, classrooms and student gathering areas, making interior activity visible from the surrounding campus.

Sustainability also played a significant role in the project. Although bird-safe glazing was not required by local regulations, the university selected BirdSmart® Bird Safe Glass by Vitro with a laser-etched 2-by-2-inch pattern across all exterior glazing. The building became a pilot project supporting the development of future bird-friendly glazing standards on campus.
