In the IN2 NEXT project, PV-coated windows from NEXT Energy Technologies were tested against traditional commercial windows, tracking performance based on their respective solar heat gain coefficient (SHGC), an industry-standard performance metric for commercial windows. The results show that NEXT Energy’s technology could lower the SHGC from an otherwise equal window to below .20.
