Pennsylvania: New Series of Windows Has Potential to Save Energy for Commercial Buildings
|Positive Impact:||The OptiQ™ Ultra Thermal Window series introduces new high-performing windows to the commercial building industry and unlocks the potential to save energy in more of America’s commercial building space.|
|Location:||Cranberry Township, Pennsylvania|
|EERE Investment:||$2.6 million; $1.3 million ARRA funding with a $1.3 million cost share from Traco|
|Clean Energy Sector:||Energy-saving homes, buildings, and manufacturing|
The project is being administered by BTO’s Emerging Technologies Program. It is the first R-5 window series for the commercial buildings sector that also surpasses the highly-efficient requirements for R-5 windows. The OptiQ™ delivers as much as a 40% percent increase in energy efficiency compared to existing commercially available double-pane low-emissivity windows. Prior to the introduction of the OptiQ™, R-5 windows were not available for commercial buildings and were only available for residential use. Higher structural requirements for commercial buildings relative to residential buildings make it more difficult to develop thermally insulated windows. The OptiQ™ currently offers two models of windows; the AA® 4325 entered the market in 2012, and the AATM 5450 was introduced at the June 2013 American Institute of Architects (AIA) National Convention in Denver, Colorado. Commercializing and deploying highly insulated windows such as the OptiQ™ provide commercial building owners and operators with more energy efficient options to reduce heating and cooling expenses. The introduction of the OptiQ™ series pushes the bounds of thermal performance for commercial windows, making R-5 windows available for entirely new markets. Further cost reductions are expected for commercial windows as manufacturing volumes increase, driving the market toward additional advances in energy efficient window technologies.
The windows are made from aluminum and are designed to never rot, warp, or buckle due to moisture and weather exposure. They also attain outstanding condensation resistance, which is ideal for healthcare and education applications where condensation and mold are significant concerns. This project is part of the Department’s broader investment in 45 awards announced in June 2010, totaling over $68.4 million in ARRA funding to advance energy-efficient building technology projects.
The Building Technologies Office leads a vast network of research and industry partners to continually develop innovative, cost-effective energy saving solutions—better products, better new homes, better ways to improve older homes, and better buildings in which we work, shop, and lead our everyday lives.
