Sage Electrochromics Inc.’s dynamically tintable window technology will be included in a Minnesota home that is attempting to become one of the first and largest homes in the United States to earn platinum certification under the LEED green building rating system. 


The 6,500-square-foot house, called “The Green Fin House,” will incorporate SageGlass windows, manufactured by H Window Co., in its south wall.  The windows’ tintable glass turns from clear to dark at the press of a button. “We feel it is the perfect way to mitigate the effects of the hot summer sun, while allowing us to enjoy our view and connection to the outdoors,” say the homeowners, who asked that their names be withheld for privacy.


Sage says its products deliver the benefits of thermal and visual comfort as well as energy savings while consuming minimal power. According to the company, it takes less electricity to operate 1,500-square-feet of glazing area than it does to power a 60-watt incandescent light bulb. In the tinted state, the glass blocks 91 percent of solar energy penetration. In contrast, standard low-E windows block 70 percent or less of the sun’s energy.


house“We feel that the windows are an important investment, not only for today, but for future generations as we look for ways to conserve energy and protect our precious natural resources,” the Green Fin House’s owners report. They add they are that they are not impressed only with SageGlass products’ control over unwanted solar heat and associated energy costs, but also their ability to mitigate glare. Instead of shutting blinds or curtains and sacrificing their view, the homeowners can tint the glass to block intense sunlight. In the darkened state, the glass allows the residents to see through their windows without enduring distracting glare and reflections on their television screens and computer monitors.

In addition, the glass blocks 98 percent of the sun’s energy that can cause fading, preventing premature replacement of furniture, carpets and wall coverings, the company says.


“We’re relieved to know that SageGlass will help protect our furniture and flooring materials from fading,” the homeowners add.


The design and construction of The Green Fin House is featured on national television program “Blueprint for Green.” Along with spotlighting the tintable products, “Blueprint for Green” will highlight many of the home’s other sustainable elements such as recovered wood, solar panels and a green roof.


The Green Fin House is scheduled to be completed by early 2009.
