Lighting upgrades involve transitioning to more energy-efficient equipment as well as installing sensors and other technology to allow lights to turn off when not needed. In residential settings, this frequently means upgrading from incandescent lamps to compact fluorescent lamps.
On the Danforth Campus, fluorescent bulbs were upgraded from T12 to T8 beginning in 1999, saving an estimated 20.6 million kilowatt-hours or 17,306 MT eCO2 over the total campus. This conversion is approximately complete on 90 percent of the campus, as buildings are upgraded as they are renovated. Currently, lighting fixtures in the garages are being converted from high pressure sodium to compact fluorescent fixtures, which will give an estimated savings of 928,832 kilowatt-hours in all the Danforth Campus garages. The garage lighting project received funding from AmerenUE as part of the Business Energy Efficiency incentive program.
On the Medical Campus, similar conversions and upgrades have been implemented. A lighting upgrade project in McDonnell Sciences also qualified for funding from AmerenUE under the same plan. Lighting upgrades at the Medical Campus are nearly complete.
