Electricity and water conservation on college and university campuses in response to national competitions among dormitories: quantifying relationships between behavior, conservation strategies and psychological metrics

“Campus Conservation Nationals” (CCN) is a recurring, nation-wide electricity and water-use reduction competition among dormitories on college campuses. We conducted a two year empirical study of the competition’s effects on resource consumption and the relationship between conservation, use of web technology and various psychological measures. Significant reductions in electricity and water use occurred during the two CCN competitions examined (n = 105,000 and 197,000 participating dorm residents respectively). In 2010, overall reductions during the competition were 4% for electricity and 6% for water. The top 10% of dorms achieved 28% and 36% reductions in electricity and water respectively. Participation was larger in 2012 and reductions were slightly smaller (i.e. 3% electricity). The fact that no seasonal pattern in electricity use was evident during non-competition periods suggests that results are attributable to the competition.

“全国校园节约竞赛（Campus Conservation Nationals，CCN）”是一项周期性举办的全国性高校宿舍水电节约竞赛。本研究针对该竞赛对资源消耗的影响，以及节约行为、网络技术应用与各类心理指标间的关联开展了为期两年的实证研究。在本次分析的两届CCN竞赛期间，宿舍水电用量均出现显著下降：两届参赛宿舍居民人数分别为105000人和197000人。2010年竞赛期间，整体用电节约率为4%，用水节约率为6%；排名前10%的宿舍，用电和用水节约率分别可达28%与36%。2012年参赛规模有所扩大，但节约率略有下降（用电节约率为3%）。非竞赛时段的用电数据未呈现显著季节性规律，这表明本次观测到的节约效果可归因于CCN竞赛本身。赛后资源使用数据收集……
