Program

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 conditionsNext 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

Prop 39 ZNE Pilot Project

Program GoalsZNE 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

Selection Criteria

• Potential to reach an EUI of 16-22 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

Prop 39 ZNE Rounds 1 and 2 Screening

Target-setting for the whole

building energy footprint

Designing to the target footprint

Building to the design

Monitoring, diagnosis and

correction

Utilities have observed that ZNE buildings can be achieved only by way of an integrated, multidisciplinary design process that includes:

Achieving ZNE

Design Consultation

Construction Inspection and Commissioning

Support

Incremental Cost Buy Down

Monitoring, Diagnosis,

Correction and Validation

Coordination with Prop 39

Energy Hierarchy

Pre-ZNE Implementation: District Offices

Current Utility Data• Electrical consumption 510,000 kWh/year• Peak electrical demand 158 kW• Average electricity cost $0.15/kWh• Average gas cost $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

CAMDUS Recommendations

Zero Net Energy – What is it?

1. Increased energy efficiency

2. Reduced operating costs

3. Resiliency

4. Insulation from future energy cost fluctuations

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 Solatubescan be primarily lit with daylight during daylight hours, (even with the blinds fully closed).

Old Fluorescent

• 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
