DESCRIPTION
From the 2010 Alliance to Save Energy Green Campus Energy Efficiency Summit – Greening the Campus, Building the Workforce
Citation preview
Stanford University Green Campus Program Laundry Efficiency Pilot Initiative
LAUNDRY EFFICIENCY PILOT PROFILE
• WHAT: Education and outreach to campus laundry facility users on efficient laundry practices.
• WHY: Inform/educate campus residents; Realize energy/water savings; Convince Stanford Housing to actively support these practices in the residence halls.
• WHO: SGCP; Stanford Housing
• WHEN: Fall Quarter 2009
• WHERE: Studios Apartments
SOWING THE SEED FOR THIS PILOT
• Suggestion of departing Sustainability Manager (Nick Kaestner)
• Laundry facility user study (2007) – Graduate student research project – Survey of 124 individuals across 6 undergraduate residences – 3 month data collection in houses with low to high washing practices
(based on # monthly loads/resident) – Key findings:
• Majority (67%) reported sorting clothes for warm/hot water cycles • 28% did so out of habit; 49% did so on account of color bleeding • 85% couldn’t tell a real difference between hot and cold cycles • 52% would consider line/rack drying • Overall conclusion: Affecting laundry use patterns could take
relatively little education and awareness building
PROJECT PLANNING
• Project Scoping Meetings: – Stanford Housing – WEB: The washer/dryer rental company – Green Living Coordinators
• Meeting Outcomes: – Housing can be a key project champion. Housing staff have
access to energy use data, they can influence the laundry equipment vendor, and are open to expanding pilot efforts.
– WEB agreed to semi-adhesive (static) stickers
– Identified Studios Graduate Complex as attractive target for pilot
• Placing static stickers atop washers
• Informational tabling
• Resident laundry attitudes & usage survey
PILOT LAUNCH
RESIDENT SURVEY RESULTS
• 90 Studios residents responded
• 80% of respondents noticed the static stickers
• 87% reported sorting clothes for warm/hot water washes
• 45% reported switching to cold water washing
• 42% reported a preference to line/rack dry clothes
PILOT EXPANSION
• As a result of resident survey, the team purchased 10 drying racks for Studios residents to check-out
• Rack usage/ frequency tracking to occur in winter quarter
PILOT IMPACTS/METRICS
• Annualized, based on November 2009 usage data and results of resident attitude & usage survey:
* Assumes 20% Studios residents switch to cold water only wash cycles 1/week.
LESSONS LEARNED
• Recruit project volunteers for broader education/outreach
• Include samples of cold water detergent as incentive and attention grabber
• Data/metering challenges: Laundry facilities not all metered separately from living areas (so natural gas reading can include heating, showers and washers.)
• More intentional planning on an integrated (washing and drying) approach
• Remain vigilant for potential roadblocks: Approval of equipment vendor; Housing/Res Life policies (e.g.: appropriate use of drying racks)
