ER-2: Student Sustainability Outreach Campaign

*On-Campus Competition: Residence Hall Energy & Water Competition As part of Green Week a competition was held between the Purdue residence halls. During a specified day residents are asked to find ways to use less power, possibly by turning off lights and other electronics, as well as limiting time in the shower, dubbed the “Three Minute Power Shower” at some of the halls. *Campus-wide Challenge: “Boiler Up, Power Down” Earth Day Challenge “Boiler Up, Power Down” is a Purdue energy conservation awareness campaign that challenges students, faculty, and staff to modify their power consumption behaviors. The program aims to create a more environmentally responsible and cost-efficient campus. One specific part of the program, “Power Down Hour” on Earth day, students, faculty, and staff were asked to power down any electronics and turn off lights whenever possible between noon and 1 p.m.

*On-Campus Competition: Residence Hall Energy & Water Competition Energy metering devices collected the data for the participating halls. Energy consumption was recorded the week prior to the competition to establish an average baseline for each hall. Shreve Hall won the energy conservation competition by reducing its average daily use per person from 9.74 to 9.09 kilowatt hours. *Campus-wide Challenge: “Boiler Up, Power Down” Earth Day Challenge Purdue Utilities monitored campus power consumption during this time and reported that demand had decreased by 2.5 megawatts during peak hours. This saved 1,468 kilowatt hours by a behavior modification, turning off lights, computers, and equipment when able. This also translates into a reduction in carbon emissions equal to taking 530 cars off the road for one hour.
