Open windows in January are a just one sign of the energy inefficiencies that plague many multifamily buildings in urban areas.
Studies of multi-family structures show wide variations in energy consumption per square foot with the least efficient buildings using seven times more energy than the most efficient. “These wide fluctuations mean many buildings are candidates for energy efficiency upgrades that can reduce costs and improve cash flow,” explains Andrew Padian, vice president for energy initiatives, The Community Preservation Corporation, New York.
