When exploring Stanford's campus, visitors might not notice the plethora of lights that illuminate their path as a sustainability initiative, but thanks to a partnership between Buildings, Grounds, and Maintenance and Facilities Energy Management, now these critical campus fixtures are outfitted with more efficient bulbs. The long-neglected building exterior light fixtures (near doorways, on exterior stairways, and under arcades or covered patios, for example) have gone through an extensive upgrade to feature new LED light sources. Nearly 1,500 lights in quads one, two, and three were upgraded this summer, with additional quads planned for the fall. The project is expected to save more than 200,000 kilowatt-hours (kWh) annually from the first three quads alone, and since the LED lamps should last at least 20 years there will be significant energy and maintenance cost savings over the life of the project.
Heading inside, as part of an ongoing sustainability partnership between Sustainability and Energy Management the Department of Athletics, Physical Education, and Recreation the Arrillaga Practice Gym and Weight Room also got outfitted with new LED lights. Funded largely by the Energy Retrofit Program, more than 65 overhead court lights now feature the energy-saving equipment. The project reduces the facility's energy consumption by 55,000 kWh per year and is expected to save approximately $8,000 in utilites costs. The new bulbs also improve light levels and usability.
