SAGE Electrochromics’ SageGlass will be included in expansion plans for the planned $325 million expansion project at the Mall of America in Bloomington, Minn. The electronically tintable glass will be installed in the large oval rotunda that covers the grand new entrance to the Mall, providing solar control and comfort. Groundbreaking for the project started in May 2014 and is expected to be completed in late summer 2015.

The expansion will include a new entrance to the Mall, featuring a 3,500-square-foot rotunda skylight comprised of more than 300 panes of SageGlass. It will enable the Mall to control the sun without resorting to shades, blinds or other devices that would have curtailed natural daylight, according to SAGE officials.

“Our objective was to maximize natural light and comfort for our guests,” says Rich Hoge, vice president of operations for Mall of America. “With SageGlass, we can control the amount of sun so that it is cool and comfortable in the Mall whether it is nine degrees or 90 degrees outside. We’ll also benefit from energy savings without having to block daylight with blinds or shades, which would have also been a challenge for us to clean and maintain in such a large, elevated skylight.”

The SageGlass installation at Mall of America will primarily operate automatically via light sensors, changing tint as the sun intensifies and moves west throughout the day. Tinting can also be controlled manually as needed for special events at the Mall that would require customized glare or heat management.
