摘 要：Based on these heating and cooling saving ranges, low-e storm windows have a technical potential energy savings that is, the energy savings that would result if all low-performing windows were covered with low-e storm windows ranging from 0.7 to 1.96 quadrillion Btus primary (source) energy. Of this technical potential, this study estimates that market adoption of low-e storm windows could reasonably achieve savings of 140 trillion Btus of primary energy annually by 2025, assuming DOE implements a number of market transformation activities directed toward low-e storm window market adoption.
