From a January 6 Cornell Chronicle article:
Cornell’s oldest and least energy-efficient environmental growth chambers — some dating back to the 1950s — that are used for research in the College of Agriculture and Life Sciences (CALS) will soon get an extensive makeover that are expected to save $156,000 annually in electricity costs and reduce annual carbon dioxide equivalent emissions by an estimated 721 tons, thanks to a timely grant from the New York State Research and Development Authority (NYSERDA).
