6 7 Goals of Sustainability Plan 1. Create a campus-wide culture of sustainability 2. Incorporate sustainability into the development of new and renovated facilities 3. Invest in renewable energy and energy efficiency programs 4. Develop a more sustainable transportation system 5. Develop a more sustainable system for the purchase of supplies and materials 6. Enhance curricular educational opportunities for sustainability 7. Establish a commitment to climate action

7 Facilities Planning & Construction Supports the mission of SBCCD through the planning and development of facilities and standards which advance learning by providing a safe, sustainable, and high-quality environment LEED and sustainability programs District standards & specifications Owner program requirements (OPR) Facilities master plan Sustainability integrated energy Energy conservation plan Waste water management plan Environmental health & safety program Saving by design Water saving plan Waste and recyclable

9 Challenges, Opportunities, Initiatives Overcoming challenges: Local obligation bonds Proposition 39 fund Capital outlay fund Energy saving Projects paid by itself saving from general fund CPCU incentives ZNE pilot program Professional consultants Events: green schools, CHESC, USGBC, CCFC, CMAA, AIA, CASH, etc. CCC/IOU Partnership Program Prop 39 SCE Zero-Net Energy Pilot Program Measure P Bond $190 Million Facilities, Sustainability & Integrated Energy Master Plans Energy Conservation Measures Measure M Bond $500 Million Prop 39 Clean Energy Act $3.1 Million

10 2017 Master Planning Sustainable facilities planning continue Sets milestones toward achieving zero net energy (ZNE) Sustainability goals for healthy environments Community enthusiasm for environmental stewardship Optimal learning conditions Next steps: Ultra-efficient building design standards Micro-grid and battery storage Fuel cell electrical generation Emerging technologies, sub-metering of all systems Electric/hybrid vehicle charging stations Online dashboard that shows power generation and power usage Retro-commissioning on a 3- to 5-year cycle

11 Prop 39 ZNE Pilot Project Program Goals ZNE projects are part of California Public Utilities Company s (CPUC) Proposition 39 ZNE for Schools Pilot Program. Funds for Prop 39, The California Clean Energy Jobs Act, are helping schools across California with the state s goals to reduce energy use and greenhouse emissions. Leverage Prop 39 funds Retrofitting existing buildings in public schools & community colleges Establish Proof of Concept of feasibility across California Document findings & Best Practices Future Program Development Prop 39 ZNE Value to Schools Socialize awareness to stakeholders District staff members, teachers, students, parents, & community Design Assistance Training Implementation & on-going maintenance of these retrofits

12 Prop 39 ZNE Rounds 1 and 2 Screening Selection Criteria Potential to reach an EUI of kbtu/sqft/year after measures are applied Project currently has Prop 39 funding or other Non-Prop 39 funds Onsite renewable will be installed at the site Funded separately from ZNE Pilot Must meet Prop 39 ZNE Pilot Schedule

13 Achieving ZNE Utilities have observed that ZNE buildings can be achieved only by way of an integrated, multidisciplinary design process that includes: Target-setting for the whole building energy footprint Designing to the target footprint Building to the design Monitoring, diagnosis and correction

14 Utility Support Design Consultation Construction Inspection and Commissioning Support Incremental Cost Buy Down Monitoring, Diagnosis, Correction and Validation Coordination with Prop 39

16 Energy Hierarchy

17 Pre-ZNE Implementation: District Offices Current Utility Data Electrical consumption Peak electrical demand Average electricity cost Average gas cost 510,000 kwh/year 158 kw $0.15/kWh $1.17/therm Existing Equipment Lower efficiency rooftop package cooling units Electrical resistance water heaters for domestic hot water needs Lighting systems were found to be 1st generation T8 lamps and lack effective occupancy and daylight controls

18 CAMDUS Recommendations

19 Zero Net Energy What is it? 1. Increased energy efficiency 2. Reduced operating costs 3. Resiliency 4. Insulation from future energy cost fluctuations 5. Societal value ENERGY CONSUMPTION RENEWABLE ENERGY BUILDING ENERGY MIDNIGHT

25 Solar PV System kw Carport Photovoltaic System 2. Provided by Sunpower 3. Added benefits of keeping cars cool(er) and reduced heat island effect from asphalt 4. Operational since Feb Performance so far meeting expectations

26 LED Lighting Retrofit in Closeout Phase 1. Retrofit solution 2. LA Lighting and EnOcean controls have been key 3. Integration with solar tubes Parabolic Troffer

27 Spectrometer Spot Measurement By: Kyle Konis Agile Environnements

28 Old Fluorescent Lighting at Open Office Workstation This grey curve is the circadian response function uw/cm2/nm EML = 98 plux = 173 M/P = 0.57 Visual response function 0.2 Not much energy is distributed in the wavelengths of the circadian response Wavelength (nm)

29 Just SolaTube Where this measurement was taken, 269 EML is achieved with just the daylight coming from the SolaTube. This measurement supports the design goal that workstations near Solatubes can be primarily lit with daylight during daylight hours, (even with the blinds fully closed). Old Fluorescent uw/cm2/nm Wavelength (nm) EML = 269 plux = 274 M/P = EML Compared with the old fluorescent light spectrum, which has sharp spikes, the daylight spectrum is broader and more even. The daylight source delivers nearly three times more Equivalent Melanopic Lux (EML), which leads to greater potential for circadian stimulus and alertness uw/cm2/nm Wavelength (nm) EML = 98 plux = 173 M/P = EML
