Deerfield runs an on-campus competition during the Green Cup Challenge. Through the month-long challenge, our students follow the success of their dormitory on our energy dashboard and compare their achievements to their on-campus peers and to other schools. The dorm that reduces its energy the most from an established baseline wins a significant prize—an on-campus activity for themselves and another dorm of their choosing, AND a cash prize proportional to dorm size. Because the Green Cup Challenge is a month-long event, we believe that the changed energy consumption practices are more likely to become a learned behavior.
