SM

Enabling Legislation •  1977 – Warren Alquist Act –  Created Energy Commission and authorizes them to them to develop and update building energy efficiency standards –  First residential and nonresidential standards developed in 1978, updated approx every 3 years.

•  1996 – AB 1890 - Electricity Research –  Assigns responsibility for administering the Public Interest Energy Research program to the CEC. Funded at $62.5M/Yr

•  1996 – AB 1890 – Energy Efficiency Programs –  Assigns responsibility for administering energy efficiency programs to the CA IOUs. Originally funded at $228M/Yr. Has now increased to over $1B/yr (filed).

What the Customer Sees

SM

Research and Development •  PIER – Technology Development –  –  –  – 

Applications focus Partnering with industry during development Vetting with IOUs and Customers Industry Alliances •  Ex – California Lighting Technology Center –  Board comprised of industry, CEC, IOUs –  Industry representation brings market perspective, manufacturing issues, business challenges, constraints

•  Industry –  Some proprietary research, competitive market –  Some cross industry issues in public domain

SM

Research and Development - continued •  PIER – Codes and Standards Research –  Several Drivers Influence Research Focus •  PIER technology research –  Fault detection and diagnostics, load shed ballasts, lighting systems that lower LPDs, attic/duct models, cool roofs

•  Code enhancement recommendations from current cycle that require additional research to refine •  Feedback from 3rd floor •  Addressing compliance/enforcement barriers

SM

IOU ET Assessments / Codes and Stds Support •  IOU Emerging Technology Assessments –  Scope driven by: •  Technologies coming out of research stream that show promise as customer programs but need further validation –  –  –  –  –  – 

Additional lab testing under specific controlled conditions Performance validation under real life conditions Parametric computer runs to simulate broad applications Identify market barriers Viability as customer program Customer acceptability (affordability, functionality, ease of use)

•  IOU Codes and Standards Support –  CASE studies to validate/strengthen codes and standards –  Compliance enhancement (improve compliance levels) •  Training and process improvement

–  Support the adoption of Reach Codes in coordination with CEC

SM

What the Customer Sees

• Title 24/T-20 Standards (CEC) • Customer Programs and Incentives (IOUs)

•  Title 24 Standards updated approx every 3 years –  Rigorous behind the scenes modeling and testing for cost effectiveness, savings potential, field issues •  IOU services to promote codes understanding and compliance •  Statewide coordination to provide customer incentives for EE technologies •  IOU services to help customers implement EE •  IOU services to help customers understand and leverage both price responsive and emergency responsive DR opportunities

SM

A Perfect Storm •  • 

Technologies are developed by PIER, DOE, Industry, others Over time, with the commitment and vision of individuals, communication between groups has increased • 

Statewide Codes and Standards Meetings • 

• 

Meetings quarterly between IOUs and CEC to share latest CASE study findings and emerging needs/issues

Statewide Emerging Technology Meetings •  • 

Meetings quarterly - participation from all IOUs and the CEC ET opportunities vetted and statewide leveraging opportunities identified

SM

Example 1 – Emerging EE Technology •  Bi-Level Stairway/Area Lighting –  PIER researched lighting devices which are dimmed during unoccupied periods

•  Exhaust Hoods – Demand Controlled Ventilation –  PIER researched technology to modulate the exhaust fan on kitchen hoods to match the effluent/temp rise • 

• 

IOUs performed ET assessments on these technologies under specific field conditions and determined viability as a customer offering These technologies are now qualified for utility incentives

Example 2 – Codes and Standards Cool Roofs  

PIER developed new duct/attic models to accurately model interactions between roof/attic elements and the thermal effects on the home’s conditioned space

 

PIER tested cool roof pigment compositions to advance cool roof products

 

IOUs performed CASE studies and computer simulations under various field conditions to determine viability

 

CEC Standards now include specific cool roof requirements/credits for both nonresidential and residential buildings

Example 3 – Emerging DR Technology Programmable Communicating Thermostats  

PIER tested the functionality of PCTs

 

IOUs further tested and evaluated communication protocols and applications for both emergency and price responsive events

 

PCTs will be a key tool customers can use to have connectivity to the utility once smart meters are in place

Conclusions •  Enabling legislation created the right functions •  Over time, through the hard work and vision of dedicated individuals, California’s public goods programs are talking to each other. There is a convergence of separately funded but related activities •  California is pulling together multiple resources and programs to create a highly leveraged public goods train in energy efficiency, driving in one direction
