Delamping is one fairly simple way to reduce energy. As the name suggests, it’s done by removing unnecessary light bulbs/fixtures in areas that are producing greater-than-needed illumination. First a lighting assessment must be made, then calculations are preformed in order to meet the Iluminating Engineering Society requirements.

Among some of the locations on campus that have benefited from delamping are the Mugar Library and 24 Cummington Street, where Professor Michael Gevelber’s spring 2008 Energy Audit Class teamed up with Facilities Management & Planning (FM&P).

At 24 Cummington Street, the class completed a pilot project on the 7th floor of the Life Science and Engineering Building sponsored by Ed Loechler from the Department of Biology. Lamps in the main hallway were removed yet adequate lighting levels were still maintained according to IESNA guidelines.  A follow up interview with building tenants two months after the project was completed revealed that the lighting change went unnoticed.

The project has been expanded to include delamping the remaining hallways on the 2nd, 6th, 8th and 10th floors.
