UW-Seattle NanoESThe basics: The $53 million dollar NanoES fulfills the second phase of a 168,000-square-foot complex located at the center of the University of Washington’s Seattle-based campus. Design goals included visual continuity with the adjacent Molecular Engineering and Sciences Building, completed in 2012, as well as energy efficiency, openness and daylighting. The NanoES building, like the adjacent MolES building, features four stories above grade and one story below. Included are research laboratory spaces, two active learning classrooms, breakout spaces and a learning center that students can use both before and after classroom sessions. Daylight flows deep into the building's interior as its laboratories and offices are separated with glass walls and doors that also maintain a visual connection between these spaces.

The players: Architect, Zimmer Gunsul Frasca Architects; general contractor, Hoffman Construction Co.; contract glazier, Herzog Glass Inc.; glass fabricator, Viracon; glazing systems suppliers, Wausau Window and Wall Systems,  Tubelite Inc. (entrances), Linetec (finisher)

The glass and systems: Herzog Glass installed more than 22,000-square-feet of Wausau Window and Wall Systems’ unitized curtain wall in units up to 16 feet tall. The majority is INvision 8250i-HRX Series 4-SSG with custom, 6-inch-deep aluminum fins at vertical members. The one lite wide by one floor tall units have interlocking vertical mullions that align with the adjacent rain screen’s stone façade.

Integrated within the curtain wall are Wausau 4250z Series zero sightline, project-out awning windows with both manual and motorized operators. In the offices, the windows are programmed to automatically open at night to provide natural ventilation and lessen energy load demands on the HVAC system.

The windows and curtain wall lites incorporate Viracon's VNE-63 solar-control, RoomSide low-emissivity, argon-filled, insulating glass.

Wausau also supplied ClearStory 24-inch-deep exterior sun shades, customized shadow boxes and  structurally glazed, unitized handrail systems for the parapet and green roof.

Tubelite provided Therml=Block entrances with thermal strut, customized electric security and automatic hardware.

The curtain wall, window and entrance systems' metal framing members, along with the shadow boxes, sun shades and accent fins, are finished with two-coat mica coating applied by Linetec.
