NYC Buildings from 1970s, 1990s Least Energy Efficient

NY energy benchmarkNew York City released its third year building energy benchmarking report, analyzing energy and water consumption data in large buildings reported in 2013. The city has over two billion square feet of buildings encompassed by benchmarking legislation.

According to the “New York City Local Law 84 Benchmarking Report,” when comparing the median energy use intensity (EUI) for multifamily and office properties by year built, median EUIs fall within consistent ranges for most properties, except for notable peaks and dips in EUI for both multifamily and office properties built in the 1960s-2000s. The peaks of high EUI for a relatively low number of properties in the 1970s and 1990s, particularly for offices, indicate that the properties built in those years are more energy intensive than properties built in other years.
