An exciting new change in Founders Great Hall indicates Haverford’s continuing effort to minimize environmental impact.
Bill Anderko, Assistant Director of Facilities Management, recently alerted CER of the recent light bulb swap in Founders. The incandescent light bulbs in Founders Great Hall’s eight large chandeliers have been replaced with LED bulbs. The work exchanged the ninety six, 60 watt incandescent light bulbs for 12 watt dimmable LED light bulbs.
The change will ultimately save energy, money, and man-hours for Haverford. The 12 watt LED bulbs will save 4,608 watts per hour compared to the old incandescent bulbs. Further, the exchange, which cost $2000, will have a payback of less than two years! Estimating 8 hours of light use per day, the school will save about $1,100 annually using the lower wattage bulbs. In terms of man hours, the new LED bulbs have 25 times the lifespan of the incandescent bulbs, so they will need to be replaced much less frequently! These new bulbs could go eight years without being replaced, while the old ones needed to be replaced several times each year. Replacing light bulbs may not sound like a big deal, but when the chandeliers are 20 feet high and require scaffolding to reach, each exchange can be a burden.
