SageGlass provides vital daylight control in Immanuel Bible Church’s new multi-function atrium

Jan. 3, 2012

The Immanuel Bible Church in Springfield, Virginia, has installed SageGlass® dynamic glass to enable state-of-the-art daylighting control as part of a multi-year, multi-million-dollar building expansion.

SageGlass provides a simple, maintenance-free way to naturally illuminate and shade the interior of the project’s centerpiece: a 58-foot-high (17.68 meters), 7,800-square-foot (2,377 square meters) multi-use atrium used as a gathering space, theatre and conference hall, as well as a video-fed overflow venue for worship services. SageGlass is installed in the atrium’s upper story with six rows of hard-to-reach clerestory windows.

The SageGlass-equipped atrium is a hub of activity. It provides a place for connection, where people can gather for conversation. It also hosts performances, concerts, movies and conferences, while the perimeter area is the site of ministry promotions. Precise lighting control is critical to the success of these various church functions.

Since the atrium’s clerestory windows are nearly inaccessible at up to 58 feet (17.68 meters) from the floor, the church selected SageGlass because it provides better light control, lightening and darkening at the push of a button without anyone needing to access the windows. According to project manager Ron Urice, the church considered using mechanized shades or blinds, but these options would have been impractical and more costly. “Blinds wouldn’t have fit in well, while mechanized shades would have required rigging, expensive maintenance, and blocked out all of the sun,” he said. “SageGlass was cost competitive with these traditional sun controls, while offering the promise of much less maintenance requirements.”

SageGlass is an electronically controlled glazing that changes tint on demand in response to changing daylight conditions, so that the glass automatically darkens or clears as needed. Immanuel Bible Church configured SageGlass controls for three settings: fully tinted, intermediate tint, and clear.

While the room-dimming qualities of SageGlass are what the church’s building committee sought during early design-phase meetings, they also wanted to optimize natural daylight in the building as much as possible to keep electrical lighting costs down. “We expect building maintenance costs to be lower because we’ll use less electricity to light the space, and there is no need to replace or repair shades and blinds,” Urice said.
