GSA Headquarters In Washington, D.C. Uses SageGlass To Solve Sun Control Problem



MINNEAPOLIS  – The federal government’s largest real estate manager, the General Services Administration (GSA), is using SageGlass® dynamic glass in its own headquarters as part of its Smart Building Initiative to incorporate new sustainable technologies in some of the government’s most energy intensive buildings.


Part of a large open courtyard at the historic GSA headquarters in Washington, D.C., has been transformed with the construction of a seven-story addition including a six-story south facing atrium with SageGlass installed in the skylights. GSA is seeking LEED® Gold certification for the new atrium.


The SageGlass skylights provide the practical benefits of optimizing daylight and reducing energy for heating and cooling, and also serve as a demonstration of green building technologies for improving energy performance in public buildings.


“The GSA has been a leader in exploring alternative building technologies for making its vast inventory of real estate more energy efficient,” said architect Mark Gilliand, Design Principal in charge of the project for Shalom Baranes Associates, Architects. “We incorporated SageGlass electrochromic glass into the atrium to demonstrate how heat gain and glare from the sun can be controlled without blocking the daylight.”


The atrium, built by the Whiting-Turner Walsh Joint Venture, connects two of the three main wings of the GSA building and serves as a public gathering space and reception area. Consequently, keeping occupants comfortable was another key design consideration for the project. SageGlass provides automatic sensor controls for maintaining a comfortable level of sunlight throughout the day. It also allows the building owners to manually adjust daylight to their liking using a remote control, such as when they want to darken the space for a presentation.


SageGlass is electronically tintable dynamic glass that maximizes daylight and outdoor views in buildings while controlling glare and heat gain. The glass can tint or clear with the touch of a button or in concert with an automated building management system to save energy and help keep building occupants continuously comfortable throughout the day.


The GSA headquarters is the latest in a series of government buildings incorporating SageGlass. Last year the agency selected SageGlass for its Green Proving Ground program, providing sun control for its LEED Gold-certified Donna-Rio Bravo Port of Entry in Texas. SageGlass has also been installed in projects at the United States Naval Academy, Argonne National Lab, the National Renewable Energy Lab (NREL), the Ajo Border Patrol Station, and the Torrington Port of Entry.

About SAGE Electrochromics, Inc.

SAGE Electrochromics is the world’s leading manufacturer of advanced dynamic glass that can be tinted or cleared to optimize daylight and improve the human experience in buildings. SageGlass controls the sunlight and heat that enter a building, significantly reducing energy consumption while improving people’s comfort and well-being. SageGlass can reduce a building’s cooling load by 20% and HVAC requirements up to 30%. It is a smarter, more elegant solution than conventional sun controls such as mechanical window shades, blinds and louvers. Now celebrating its 10th year anniversary shipping SageGlass commercially, the company was founded in 1989 and is headquartered near Minneapolis-St. Paul, Minn., in the heart of “the Silicon Valley of the window industry.” SAGE is a wholly owned subsidiary of Saint-Gobain of Paris, the world’s largest building materials company.
