You would think that as time went on — and technology improved — buildings would consume less energy.In New York City, at least, that does not appear to be the case.
A new report from Mayor Bloomberg’s office on energy use intensity found that the city’s Art Deco/1930s-era gems also happen to use almost the same amount of energy than the quasi-brutalist structures of the 1970s.
For offices, efficiencies have only gotten worse.
“Clearly there are a lot of other factors other than age that are influencing energy use,” the study concludes. “When viewed in five-year increments, the office sector shows considerable fluctuation, but still exhibits a strong underlying upward trend. The multifamily properties seem to grow on average steadily more efficient from 1900 to 1940 and become steadily less efficient between 1945 and 1975, after which they exhibit more volatility.”
