Enormous Potential Seen in NYC for Cost-Effective Energy Retrofits

摘要

The first benchmarking report mandated by New York City's energy ordinance is pinpointing the most promising targets for efficiency projects.The report breaks out 2010 data by building type for private properties with more than 50,000 square feet (see chart). For all types, the data shows that the most inefficient buildings commonly use three to five times as much energy as the most efficient buildings. In the case of retail buildings, the difference was nearly eight times. For each type, the analysis compared buildings with similar levels of heating and lighting.
