Dynamic glass catches on at major airports
By John Caulfield, Senior Editor
Next month, nine remodeled gates inside Terminal 1 at San Francisco International Airport will reopen, with another nine scheduled to reopen in March 2020. The $2.4 billion remodel of this terminal should be completed in 2023.
This 1.2-million-sf net-zero-energy space, designed by Gensler, will include 57,000 sf of dynamic glazing supplied by View, a 12-year-old company based in Milpitas, Calif., that currently has its product in six of the top 15 airports in the U.S.
For example, the Terminal A expansion at Charlotte (N.C.) Douglas Airport included 20,000 sf of dynamic glass, with gate walls that are 40-ft-tall by 50-ft-wide glass walls. “We can do large-format glass that’s critically important to airports,” says Brandon Tinianov, View’s Vice President of Industry Strategy.
Unlike thermochromic glass that responds directly to changes in sunlight and temperature, View’s glass uses nano-layers of electrochromic coating on its surface. When voltage is applied, the glass tints. View’s intelligent system allows the windows to respond to the surrounding environment automatically, to eliminate heat and glare. Tinting of windows in rooms can be controlled by zones.
Tinianov concedes that the upfront cost for View’s glass is a barrier to entry for some clients. That’s why View emphasizes longer-term operating cost benefits, which can be substantial when HVAC systems can be downsized. View claims that its dynamic glass reduces a building’s energy consumption and costs by 18% annually, and can block more than 90% of solar radiation, thereby reducing peak cooling loads by 23%.
Tinianov also points to DFW International Airport in Texas, where View participated in a pilot study to gauge the relationship between passenger experience and revenue. A restaurant near two gates that was underperforming saw its revenue increase, on a year-to-year basis, by 102% after View installed dynamic glass on its eastern façade, says Tinianov.

Since the company’s inception, View has installed its glass in 50 million sf of buildings. Airports represent about 20% of View’s project portfolio. Healthcare and multifamily account for 10% each. And offices represent 60%. “The big value is office towers with thousands of windows,” says Tinianov. This month, the city of San Francisco and the developer Related topped off 49 South Van Ness, a 430,000-sf office building designed by Skidmore, Owings & Merrill that features View’s smart glass.
“We believe that a core role of architecture is improving human performance and enriching the human experience while using as few resources–particularly energy–as possible. The dynamic glass in this building plays a huge part in achieving those goals.” says Mark Schwettmann, SOM’s Design Director.
During the design phase of San Francisco’s Terminal 1 remodel, the building team evaluated six different sustainability measures, and, according to Tinianov, the scenario that included dynamic glass performed the best.
View sees growth potential in promoting dynamic glass for sustainability, health/wellness, and security. Every View installation now includes a smart building platform that consists of power, network, and communication infrastructure. This will allow View to add apps that can help manage a building’s physical and digital security, air quality, and acoustic levels.
Last November View partnered with Microsoft to launch SmartProtect, a window-based security solution that automatically detects glass breakage. The app leverages Microsoft Azure IoT service, Azure Digital Twin.
