According to a 2010 article in "The Oberlin Review", renovated dorms may use more electricity. This is the case for several dorms renovated during the summer of 2008. The College architect, Steve Varelmann, has called the numbers "erratic and possibly unreliable." According to Varelmann, a possible explanation for this phenomenon is that previously non-functioning equipment started functioning again after the renovation. Students may also be at fault for their behavior: "What electronic devices are they using? Are they voluntarily reducing light usage? Are spaces experiencing increased use due to the improvements achieved from the renovation?" John Scofield, professor of physics at Oberlin concluded that "We are building more and more efficient buildings, yet we're using more energy."
