1 SONOMA COUNTY JUNIOR COLLEGE DISTRICT Sustainability Summit 2018 SRJC s Sustainability Story March 30, 2018

2 Sustainability is Meeting the needs of the present without compromising the ability of future generations to meet their own needs. ~Brundtland Commission, 1987 ls

3 STEPS towards Sustainability at the Sonoma County Junior College District Santa Rosa Junior College (SRJC): 1. Strategic Plan: Sustainability was included in the vision, goals and objectives of the Strategic Plan, approved by the Board of Trustees, in the Fall of Education Plan: Sustainability became more robust when included in the Integrated Environmental Planning Committee (IEPC), a part of college governance. 3. Sustainability Plan: A Sustainability Summit was held on March 6, 2015, and over 25 participating staff & students drafted the GreenPrint 18 green goals for The document set a 3 year timeframe to change operational practices, facilities & culture. 4. Facilities Master Plan: Gensler was hired as the Facilities Master Planner due to the inclusion of a Sustainability Specialist on the team. 5. Implementation Plan: Bond Spending Plan approved by the Governing Board, included $31.5M in sustainability projects. 6. Small Wins: Install bike repair stations, water refilling stations, electrical charging stations 7. Large Wins: SRJC s FMP won a CCFC award for planning, due in part to the inclusion of a sustainability plan within the document. 8. Public Events: Ribbon cutting ceremony for phase 1 PV project, included a switch on ceremony and press release.

8 Progress: Create a buzz! Establish Baseline Metrics: Established for energy, water, waste FY Energy Baseline: Electricity: 14,437,088 kwh Natural Gas: 616,789 Therms Total Energy Usage (Electricity + Gas): 110,926 MMBTU s (1 MMBTU = 1,000,000 BTUs) Water Baseline: Districtwide Water Usage: 45,894,746 gallons (potable water only) Waste Baseline: Data is available and being reviewed Transportation: Calculations complete by June 2019 Carbon Footprint: Goal to complete Scope 2

9 Progress continued Integrate Sustainability into Operational Procedures: Purchasing policy is being reviewed. Create a standard for the % of goods purchased within a sustainable threshold Incorporate Sustainability into Master Planning Documents: Establish LEED as a building standard CCFC award for best master plan in 2017, which included a sustainability plan Continue to seek state funding: Proposition 39 provided 496 LED retrofits in the parking structure Improved safety & security with a 50%, reduction in KW use Align templates with Chancellor s Office: Utilize CCCCO sustainability action plan template Template includes goals for energy, waste, water, transportation, built environment, land use, & education

10 Progress continued Partner with City and Community Transportation Agencies: Free student ridership on Sonoma County Transit beginning in 2018: Sonoma County Transit City Transit system Leadership Institute SMART Raise Awareness One Event at a Time Zero-waste events with 90% diversion Lumafest Day Under the Oaks Utilize Existing Energy Saving programs: PGE interns Savings By Design Social Equity: Food distribution point is being established on each campus.

41 FULL SIGNAL Construction Project Procurement part 2 THE HAWK FULL SIGNAL

42 SRJC Micro-Grid Project Preliminary award to three of 36 proposals! #2 = 93.25, #3 SRJC = 89.00, #4 = Group 1 = 16, Group 2 = 11, Group 3 = 36 Primary application (not Option 1) $5M funding combined with $14.4M for combined $19.4M Solar & battery Storage Micro-grid Project

43 Process Map out electrical infrastructure and Point of Common Coupling (PG&E meter and main breaker)

44 Identify each building s electrical load and generation assets. Use Campus electrical meter and code based analysis per square footage when individual building sub-meters don t exist

45 Match load to generation Develop a load-shedding strategy Prioritize buildings or building systems from highest to lowest

49 Risks New Software Technology: Software glitches can potentially affect PV and Battery usage, leading to less cost savings. New Battery Technology: Battery storage is commercially viable but risks exist in battery maintenance & equipment lifetimes. Faulty Signals: A faulty signal can shutdown a building; FacOps would have to energize the building locally. Long project duration with CEC: Project duration is June 2018 to June 2022 if grant is formally awarded. Space and Aesthetics: Battery storage technology is the size of approximately 4 parking spaces.

50 Benefits Annual cost savings to District: $48,370 per year. Participation in PG&E's demand response program is between $26 & $48,000 per year New value-added revenue stream: Curriculum and Knowldege: Development of trade specific knowledge about micro-grid systems with the potential to develop curriculum around installation, operation & maintenance. Improved Emergency Operations: The prevention of power outages is import, as demonstrated in the recent Sonoma County fires. Leadership: This is the first large scale commercial micro-grid in Sonoma County & 100% based on renewable energy.
