WASHINGTON — The Energy Department’s Advanced Research Projects Agency-Energy (ARPA-E) today announced $31 million in funding for 14 projects as part of ARPA-E’s newest program: Single-Pane Highly Insulating Efficient Lucid Design (SHIELD). SHIELD project teams are developing innovative window coatings and windowpanes that could significantly improve the energy efficiency of existing single-pane windows in commercial and residential buildings.
“The SHIELD program illustrates ARPA-E’s commitment to supporting transformational technologies,” said ARPA-E Director Dr. Ellen D. Williams. “By creating novel materials to retrofit existing single-pane windows, SHIELD technologies can dramatically improve building efficiency and save energy costs for building owners and occupants.”
The SHIELD program will accelerate the development of materials that could cut in half the amount of heat lost through single-pane windows without replacing the full window. Many buildings have single-pane windows that do not insulate a building or its occupants well. However, complete replacement of single-pane windows with efficient, modern windows is not always feasible due to cost, changes in appearance and other concerns. Retrofitting, rather than replacing single-pane windows, can reduce heat loss and save roughly the amount of electricity needed to power 32 million U.S. homes each year.
The 14 SHIELD project teams are developing applied products and manufactured windowpanes, which can be installed into the existing window sash that holds the windowpane in place. These window technologies will improve thermal insulation, reduce condensation and enhance occupant comfort. The materials could also produce corollary benefits, such as improved soundproofing, that will make retrofits more desirable.
