2 Fostering Sustainability in Schools Portland Public Schools Nancy Bond

3 Resource Conservation Specialist Reduce utility budget Change behavior Develop policy In 10 years, my work has saved Portland Public Schools more than $7.5 million

4 Today s presentation Utility bill review Energy conservation Solid waste management Stormwater management Interdepartmental collaboration Green building occupant education

5 Utility Bill Review Watch for: Correct rate schedule Unwarranted fees (late fees, service charges) Spikes Misread meter? Leak? Irrigation? Bad behavior? Billing system malfunction?

6 Leak Credit Normal = ~ $2,000 Previous bill = $8,116 Credit = $4,241.19

7 Irrigation Previous = $6,500 Current = $18,605 Service Date = July

8 Billing system meltdown Normal = $4,439 Not normal = $234,897

9 Correcting Utility Errors Internally, work with: Accounts Payable - watch bills Maintenance staff - alert to leaks Also work with utility service provider: Correct rate schedule Get credit for leaks, overcharges And watch for: Double billing That it s your property That it s a current account

10 Utility Bills: Review Watch for trends = opportunity to change behavior Monthly Electricity Use for Buckman 40,000 30,000 20,000 kwh 10, /05 04/05 07/05 10/05 01/06 04/06 07/06 10/06 01/07 04/07 07/07 10/07 Electricity Use 01/2005 thru 12/2007 Annual Trend

11 Energy Conservation Power Patrol Focus on behavior change

13 Energy Challenge Compare kwh to previous year (Jan Mar) Goals: Reduce energy consumption Teach students about environmental impact of different energy sources Teach students how to reduce energy consumption in schools and at home Educational outreach deliverables: Classroom presentations, assembly, signs, posters schools participate

16 Energy Challenge Results 2008 savings = $5,003 = 4% 2009 savings = $5,851 = 6.5%

17 Waste Reduction and Recycling District wide recycling program Oregon Green Schools certification program State-wide program: 3 levels of certification Focused on behavior change Includes recycling, buying recycled, energy conservation PPS has 28 certified Oregon Green Schools (2 premier and 5 merit schools with 11 in the application process)

18 PermanentwareTrays PPS discards more than 20,000 polystyrene trays per day $14,000 grant to purchase 2500 trays for 9 schools

19 Results Saved nearly $6,000 in avoided disposal costs No measurable increase in electricity or water/sewer costs Plan to roll out districtwide beginning 2010

20 Stormwater Management More than $1 million/year in stormwater fees Goals: Reduce stormwater in pipes Gain Clean River Rewards stormwater credits Create educational opportunities for students, staff, community

26 Results More than $54,000 in retroactive credit More than $60,000 annually on-going Clean River Rewards credits

27 Interdepartmental Collaboration Nutrition Services Trays Fork it Over! 62 tons in 5 years Warehouse Textbooks, surplus donations Procurement Buy recycled Surplus office supplies web page

28 BESC Green Team Educational Outreach and Process Change Bi-monthly electronic green tips to all BESC PPS employees Answer queries from employees Bulletin board celebrating sustainability projects in district

29 BESC Green Team BESC Green Team includes volunteers from 11 departments Energy, solid waste projects Promoting one garbage can per department Custodians replace plastic bag only when soiled Water dispenser/glasses for Board Night audit Turned off BESC fans after 6 p.m. (saves $31,346/yr) Set sleep function on some computers, copiers and printers

30 Results: Real savings (since Dec 2008): $31,346/yr achieved Potential savings: additional $12,700/yr identified from these initiatives

31 Two big successes Night survey - Finance (28 computers) District-wide change on copier settings: to sleep after 5 minutes, saves $150,000/yr

32 Green Building - Partnerships Rosa Parks Housing Authority of Portland owns property Boys and Girls Club shared space and utilities Result: LEED Gold school for fraction of cost

33 Evans-Harvard High Performance Classroom at davinci Arts MS

34 Partners Construction Team: SRG Partnership Inc.: Architect Todd Hess Building Company: General Contractor PBS Engineering: Project Management Funding Partners: Oregon Department of Energy City of Portland - Green Investment Fund davinci Arts Middle School - school fund raising Business Energy Tax Credit (OR Dept of Energy) Mark Edlen - personal gift Bonneville Environmental Foundation Energy Trust of Oregon Plus 32 other donors!

35 Education goals How to: Use building as designed Maintain the building Use building as teaching tool Connect occupants with their built and natural environments

79 ESCO Projects: McKinstry Energy Services Updating lighting to more energy efficient fixtures and layout Updating major mechanical systems (e.g., boilers, heating, ventilation systems) Only 3 steam heating systems, to be tested for efficiency Installing new trash compactor Installing a complete control system to aid in strategic scheduling and controls All systems to be commissioned to ensure visibility of savings and results

80 McKinstry Estimated Savings Estimated Utility Rebates from Energy Trust of Oregon, BPA, and existing SB1149 accrued funds $536,430 Estimated Business Energy Tax Credit $135,521 Total estimated annual energy savings $195,017 By implementing these building improvements, CO2 emissions will be reduced by 2,412,589 pounds annually, which is equivalent to removing 162 cars from the road or planting 330 acres of trees.

81 Energy Savings Guarantees Where McKinstry has direct control, it is prepared to guarantee any portion of a project. Where McKinstry does not have direct control (such as burn hours associated with lighting), McKinstry is prepared to work with the district to devise a method of Measurement and Verification (M&V), which will provide the highest degree of assurance that the energy cost savings exist.
