By conducting a lighting retrofit, the New York Times skyscraper has been able to reduce electricity used for lighting from 1.28 watts per square foot to just 0.38 watts per square foot.
The 70 percent reduction translates into yearly savings of $30,000 per floor. In all, it adds up to nearly $600,000 in savings for the New York Times, according to a press release.
Additionally, the retrofit has resulted in the elimination of 1,250 metric tons of CO2.
The building has sensors to take advantage of natural lighting, with perimeter lighting zones turned off when more outdoor light is available. When the sun is too bright, shades are automatically drawn down.
