EPA National Building Competition

For two years running, Columbia has entered buildings into the EPA’s National Building Competition, a nationwide competition to see who could reduce energy waste the most. Columbia’s School of Social Work achieved an 11.54 percent reduction from its starting energy use intensity (EUI), effectively preventing the emission of 187.3 MtCO2e, equivalent to eliminating the electricity use of 23 homes for an entire year, or to the carbon sequestered by 4,803 tree seedlings grown for 10 years.
