The winner of this year’s Green Cup Challenge will have its school flag fly over the campuses of the other two participants, as an added incentive for reducing electricity consumption

The Green Cup Challenge, an annual energy conservation competition, began on January 16 and will end on February 13. This year, the Lawrenceville School entered the competition against Deerfield Academy and Andover. Last year, Andover only competed against Deerfield, though in previous years Andover has participated against more schools.

This year, each dorm’s percent in energy reduction is calculated from the baseline of the dorm’s electricity consumption during last year’s Green Cup Challenge.

As of Thursday morning, Andover is in first place with a 2.1 percent or 790 kWh overall reduction, according to “Gunga Data,” or Building Dashboard, a system that tracks electricity usage in buildings at Andover and on other school campuses. Lawrenceville has saved 755 kWh, equal to a 2.0 percent reduction, while Deerfield has increased energy usage by 4.2 percent or 1174 kWh.

“The challenge serves as an opportunity to raise awareness about a variety of topics—from ways that individuals play a role in energy conservation to the larger issue of climate change,” wrote Rebecca Hession, a faculty coordinator of the Green Cup Challenge, in an e-mail to The Phillipian.

Throughout the duration of the Green Cup Challenge, Andover will also hold an intra-school competition between the 26 dorms connected to Gunga Data. Fuess House is currently leading with a 35.6 percent reduction, followed by Carriage House with a 34.6 percent reduction and Andover Cottage with a 24.4 percent reduction, according to Gunga Data.

The top three dorms with the greatest energy reduction percentage in comparison to last year’s energy use will win either a Chipotle munch, a Fisichelli’s cake munch or cups and plates for the dorm, said Hession.

“All house counselors are asked to work with their dorms on sustainability and in a dorm that means energy conservation and solid waste reduction among other things,” said Trish Russell, Sustainability Coordinator. House counselors are joined by Environmental-Proctors (E-Proctors), students who are designated to serve as their dorms’ authority regarding matters of sustainability, and members of the Eco-Action Club.

“In my dorm I tried to embrace the Green Cup Challenge as not only a movement to reduce the amount of electricity used, but also a movement to reduce the amount of water and other resources used. I made an ‘I Pledge’ sheet, where everyone signed up to pledge to do a different task, such as, ‘I pledge to turn off the water while I am brushing my teeth’, or ‘I pledge to unplug my phone charger when my phone is not charging,’” said Zoe Chazen ’14, E-Proctor in Adams Hall.

“We think a lot of people gravitate towards competition, so we sponsor the Green Cup Challenge so that people’s initial goal is just to turn off the lights so that they can win. We ultimately hope to connect that to just being green for its own sake,” said Justin Wang ’13, Eco-Action Co-Head and E-Proctor in Pease House.

“Putting up posters, reminding your friends and just being a presence in a dorm are all effective ways to encourage your friends to participate,” he continued.

In 2012, Andover lost to Deerfield for the second year in a row after Deerfield reduced its campus electricity use by 7.8 percent, compared to Andover’s 3.7 percent.

Last year, the top three Andover dorms with the greatest electricity reduction were Eaton Cottage with a reduction of 25.4 percent, Pemberton Cottage with 15.1 percent and Bancroft Hall with 13.5 percent.
