A widely known example is the 2010 retrofit of the Empire State Building (United States Green Constructing Council 2008 , Buhayar 2009 , Harrington and Carmichael 2009 , Vaughn 2012 , Empire State Building 2014 ) after it was individually retrofitted from single to double glazing, making additional savings harder and costlier. The integratively designed complete-constructing retrofit still lower web site energy use 38%, from 277 kWh m−2 yr−1 (barely below the US workplace median of 293) to 173 kWh m−2 yr−1. A lot of the effectivity features had been paid for by $17.four million capital savings from making the cooling systems one-third smaller to match the lowered cooling load, fairly than replacing them with larger new ones (plus larger electrical risers).
