New Office Buildings Less
Energy-efficient, Study Finds
Post-war office buildings use 72% more energy than pre-1914 office buildings, according to a new study released by the federal Department of Energy.
The report reveals that while buildings erected prior to World War I consume an average of 65,000 British Thermal Units per square foot annually, those built after 1946 average 112,000 btu's. A btu is the energy required to increase the temperature of one pound of water by one degree Fahrenheit.
The study, a joint effort by the Tishman Research Corp. and Syska & Hennessy, said the new buildings were overheated, overcooled and overlighted. The researchers studied 1,037 office buildings in New York City for three years. The buildings had a total of 250 million square feet of space.
