IAA retrofits lighting systems to cut energy use, CO2 emissions, and costs

How many light bulbs does it take to change your carbon footprint by more than 5,200 metric tons per year for the better? In September, the IAA finished the last of more than 2,800 lamp replacements in the IND parking garage and Indianapolis Maintenance Center (IMC), resulting in a reduction of 5,233 metric tons of CO2 emissions per year.

The improvement in CO2 output created by the replacement lights is equivalent to removing more than 1,000 cars from the city’s roads annually. The two projects will also produce combined annual savings for the IAA of more than $250,000, driven by the lower energy usage and reduced replacement costs of the longer lasting new bulbs.
