NEXT’s Innovative PV Windows Show Significant Energy Efficiency Promise

NEXT Energy Technologies Inc. announced the results of a multi-year photovoltaic (PV) window project, which it completed as part of the Wells Fargo Innovation Incubator (IN2). The project shows the overall energy-efficiency performance of NEXT’s transparent PV windows compared to traditional commercial windows.

The results of the study indicate that NEXT’s technology could lower the solar heat gain coefficient (SHGC) from an otherwise equal window to below .20.

“These are extremely significant results for the energy efficiency of insulating glass,” said Garret Henson, vice president sales and marketing at Viracon, an investor in NEXT Energy. “Achieving a SHGC below .20 while providing neutral aesthetics has been a monumental challenge for all of us that create vacuum deposition architectural coated glass. Balancing performance and appearance is the heart of ideal harmony and it appears NEXT has done just that.”
