  New
exit signs in HSPH buildings are appropriately green in color. They consume
only one-quarter watt of electricity per fixture compared to the more common
red-colored exit signs, which consume up to 40 watts per fixture.
HSPH Operations estimates the installation of the new signs will save the school $4,700 per year. To further promote energy efficiency, Operations will start installing occupancy sensors in the Kresge Building, starting the week of June 16. The sensors will replace light switches in offices. They will automatically turn lights on when someone enters a room and shut lights off when the space is unoccupied. There will also be a manual switch on the sensors to turn lights off. Operations estimates the sensors will save about $13,000 in electricity costs each year. Corridor lights are now controlled by computer so that they turn off during hours when the school is less occupied, saving about $17,000 per year. These energy conservation measures will prevent the annual release of 79 tons of CO2. The gas is created when fossil fuel is burned to produce electricity, indirectly heating the earth’s atmosphere. Operations is working with the Harvard Green Campus Initiative on the energy conservation efforts. Contact Dan Beaudoin at daniel_beaudoin@harvard.edu for more information.
