ENERGY-EFFICIENT WINDOWS INSTALLED AT SOLAR DECATHLON HOUSE
The house being built on campus by the team entered in the Department of Energy's Solar Decathlon is getting closer to completion every day. One of the latest additions was super energy-efficient windows.
A major factor in the energy efficiency of Unit 6 Unplugged is the windows, which are being provided in part through a gift by Henselstone Window and Door Systems, a manufacturer based in Warrenton, Va.
The first of the windows arrived on June 22. Jodi Knorowski, an ODU environmental engineering master's student who is the lead construction engineer for Team Tidewater, showed visitors how the windows will benefit the house in the quest for net-zero energy use, by both deflecting and trapping heat, and by being movable so the front portion of the home can convert into a patio.
Depending on which side of the house the windows are on, they have either a double- or triplepane design, serving the different insulating functions.
"For the three windows on the southern exposure we used a double-paned glass, because in the colder months when the sun is low, we want to get as much heat into the house as we can through them. All the others are triple pane so we don't lose the heat," explained HU's Jordan Smith, lead student architect for Team Tidewater.
The windows, which were designed by Henselstone Window and Door Systems, have a unique design and can open in two directions, thanks to hinges on the bottom. Henselstone vice president Ruediger Eder said the company was eager to apply its innovation to Team Tidewater's Solar Decathlon entry, because it sees some of the same ingenuity in the ODU and HU students. "This is a very smart design. And in the summer they use the solar room as a porch so the window is basically opened, Eder said. The windows on the front of the house have two air spaces filled with argon gas to help with insulation, he added.
Construction work on the Team Tidewater house will continue at its current site across from the Student Recreation Center until early August. Then it will be disassembled and trucked in pieces to Washington, where it will be reassembled on the Solar Decathlon competition site.
