Eastman donates its Heat Mirror® insulating glass to Appalachian State University's Solar Decathlon Team

Overview

WHO

Appalachian State University’s entry for the Solar Decathlon Europe 2014

WHAT

The Solar Decathlon competition was created in 2002 by the U.S. Department of Energy to challenge collegiate teams to design and build a home exclusively powered by solar energy, while utilizing innovative energy technology and sustainable architecture. In 2014 team Réciprocité, a collaboration between Appalachian State University (US) and Université d’Angers (France), used Eastman’s Heat Mirror® insulating glass in the construction of its energy-independent, row house concept Maison Reciprocity.

NEEDS

Maison Reciprocity was an innovative two-bedroom, two-bath row house comprised of three components: the Urban Shell, an energy-efficient structural envelope; the CHORD, a building systems core; and the living Brise-Soleil, the building skin components that produce energy and provide shelter. Team Réciprocité’s goals were to build a market-ready, affordable and adaptable house with a focus on the community. Constructed in Boone, North Carolina, the structure was built, tested, disassembled, packaged and shipped all the way to Versailles, France, where Team Réciprocité rebuilt the entire structure in just ten days in order to be judged and critiqued during the competition.

MATERIAL

“The choice of working with Eastman was clear for Team Réciprocité,” explained Jason Miller, faculty director of Design. “Eastman Chemical is an international company producing globally relevant and sustainable building products in our own backyard. The opportunity for a collaborative relationship was evident from the beginning.” Maison Reciprocity features Eastman’s Heat Mirror® insulating glass (IG). Set into door and window frames provided by Ply Gem, Heat Mirror® technology suspends one or more lightweight films inside the airspace of the IG unit to create multiple super‐insulating cavities — without adding weight — that buffer against heat loss or heat gain. Heat Mirror IG helps to reduce energy costs by enabling “windows that insulate like walls” with center-of-glass thermal performance up to R20 (.05 U‐value), while also maintaining a quiet and comfortable internal environment and protecting the home’s furnishings from fading by blocking over 99.5% of harmful UV-rays.

WHAT’S NEXT

“This opportunity is a reflection of Eastman’s ongoing commitment to sustainability,” explained Godefroy Motte, Eastman’s senior vice president and chief sustainability officer. “Projects such as the Solar Decathlon demonstrate how business and education can partner together to advance innovative, sustainable solutions.”
