Background

• In the Phase I Energy Efficiency Decision (D.14-10-046), the California Public Utilities Commission (CPUC) identified Proposition 39 (Prop 39) as an opportunity to expand California’s progress on deep retrofits and Zero Net Energy (ZNE) retrofits

• The CPUC directed the four investor-owned utilities (IOUs) to develop a deep ZNE-focused program for eligible local educational agencies (LEAs) and community colleges in 2015

• A program proposal Advice Letter (AL) is due on February 13, 2015

ZNE: The “What” Concept

• A building that produces as much energy as it uses on an annual basis

Requirements

• The energy produced must come from renewable, on-site sources

• The end uses within the building must be highly efficient, reflecting best practices for highly efficient buildings

Accounting methods and metrics:

• There are several, but the differences are relatively small and not significant for our purposes today

7

ZNE: The “Why”

ZNE supports GHG reduction goals per AB 32, “The Global Warming Solutions Act” of 2006: requires GHG reductions to 1990 levels by 2020. California ARB is the lead agency; multiple agencies involved.

Buildings have direct GHG emissions (from on-site combustion) and indirect GHG emissions (from electricity use): in the range of about 30% of all GHGs (variable regionally, annually, by specific accounting method, etc.)

IOU involvement on the demand side is guided by the CPUC’s California Energy Efficiency Strategic Plan issued 2008, updated 2011: goals for ZNE residential and nonresidential new construction--and for existing buildings

The CEC has adopted these goals as well, and is targeting the building code to require ZNE by 2020 for residential new construction and 2030 for commercial

ZNE: “The How”

1. Set a ZNE Target

2. Design to the Target

3. Build to the Design

4. Monitor, Diagnose, Correct, Validate

9

ZNE: “The How” 1. Set a ZNE Target Target for consumption (first)

Sizing of renewables

2. Design to the Target Commit to integrated design Choose the right mix of measures Model the building design Iterate to get to zero

3. Build to the Design Resist (“de”)-value engineering Inspect construction rigorously Commission systems rigorously

4. Monitor, Diagnose, Correct, Validate

“Something will go wrong” Identify systems not performing at predicted level Make corrections

ZNE: The “How”

Note: This is one example from a new construction project for illustrative purposes only

Proposed Pilot

• Objectives:

• Perform ~12 ZNE retrofit demonstration projects (exact number to be specified) within school district and community college campuses

• Document findings and best practices specific to ZNE existing school building retrofits

• Educate and train school district staff on the principles of ZNE

18

Proposed Pilot, Cont.

• Five Elements: 1.0. ZNE Demonstration School Retrofits

2.0. Case Studies, Technical Training, Outreach and Recognition

3.0. Institutional Training

4.0. Codes and Standards Coordination and Emerging Technologies

5.0. Production Program Development

19

Element 1: ZNE Demonstrations

• Small scale, proof-of-concept demonstrations for approximately 12 schools statewide.

• The Pilot will focus on existing school buildings

• Each IOU will implement the demonstrations independently

• Support will begin in 2015 and continue for 2-3 years

• Pilot funds will reflect Prop 39 allocations with the majority (60-80%) dedicated to K-12 schools and the remainder to community colleges.

20

Element 1: ZNE Demonstrations, Cont.

• Sub-elements:

1.1 Design consultation

1.2 Construction inspection and commissioning support

1.3 Incremental cost buy-down

1.4 Monitoring, diagnosis, correction, and validation

1.5 Coordination with Prop 39 application process

From a Participating School’s Perspective…

The ZNE Pilot will provide:

• Design assistance

• Trainings on how to socialize the ZNE concept with stakeholders (e.g. parents, teachers, students, board members)

• Ongoing commissioning and construction inspection

• Training on how to maintain ZNE operations

• Monitoring, verification

And the ZNE Pilot will require:

• Written commitment to the Pilot

• A willingness to design and retrofit a ZNE building

• A healthy budget

• A willingness to share experiences with other interested schools
