“RENOVATE” System Retrofits Providing Comparable Energy Savings

40-year-old Philadelphia high-rise exemplifies new benchmark for energy efficiency in older buildings. The RENOVATE by Berkowitz™ (Renovate) window retrofit system has enabled 400 Market Street, a 12-story building in Philadelphia, to reduce its annual heating and cooling energy consumption by more than 25 percent and significantly improve indoor comfort according to results from a year-long study funded by the U.S Department of Energy.
