HVAC Working Group Mission

• AB 2021 directed the CEC to
• Develop a suite of strategies to reduce the
  energy and peak use associated with the design,
  selection, installation, and maintenance of new
  HVAC systems.

4
HVAC Strategic Plan Purpose

• Recommend to the Legislature viable strategies,
  demonstrations, and tests for some or all
  strategies
• Provide the CPUC and its utilities guidance for
  their 2009-2020 strategic planning process

5
California Residential and Small Commercial HVAC
Demand

• Growing faster than overall demand for electrical
  energy
• Major contributor to peak electrical demand
• From 6 in 1976 to 25 in 2006 for residential
  systems alone.

6
California Residential and Small Commercial HVAC
Demand

• Residential A/C installed in new homes has
  increased from 25 in 1976 to 95 in 2007.
• Home sizes have increased by 55, from 1,560 ft2
  to 2,390 ft2.
• The result has led to a dramatic increase in
  generating capacity required to meet the
  demandfrom 1,950 MW (2 nuclear units) in 1976
  to 12,000 MW (12 nuclear units) in 2006.

A/C Appliance Standards

• The energy efficiency SEER ratings for
  single-phase A/C units increased from 7.0 SEER in
  1977 to 13.0 SEER in 2006.
• Thus, energy usage requirements for the same
  sized A/C unit were reduced by 46 over 30 years,
  if SEER ratings were directly transferable to
  peak (EER ratings).
• Without these appliance improvements, peak demand
  would have increased another 8,000 MW (another 8
  nuclear units) to keep up with demand.

The HVAC Market
Contractors
Manufacturers Distributors
Customers
11
Customers

• Customers are not used to asking for or
  recognizing quality installations for HVAC
  systems

• HVAC systems are often not properly sized
• Installation quality is often poor for new or
  replacement systems
• Customers assume that their unit is being
  installed properly

12
Contractors

• Contractors are not used to selling quality
  installations for HVAC systems

• Competitive business model driven by low first
  cost
• Lack of trained technicians and contractors
• Installation quality is often poor for new or
  replacement systems
• Over 90 of HVAC installations have either not
  pulled permits or have not been inspected

13
Manufacturers Distributors

• Manufacturers are not developing high efficiency
  equipment and not requiring quality installation

• HVAC parameters are not optimized for
  Southwestern climates
• National standards set to 82F mild and humid
  climates
• Efficiency performance degrades as ambient
  temperatures increase
• RD process is long and cumbersome

14
The Solution
Public and Private Utilities
HVAC Contractors
Manufacturers Distributors
State, and Federal Regulators and Agencies
Academia and RD
End Users
Trade Associations and Labor
15
High Level Goals for the HVAC Market

• Goal 1 Increase Quality Installation and
  Maintenance
• Increase quality of installation and maintenance
  of Central A/C Systems to achieve additional
  energy and peak savings.
• Goal 2 - Accelerate Market Penetration of New
  Equipment Technologies
• Accelerate market penetration of new equipment
  technologies that are more energy and peak
  efficient than existing equipment, and perform
  better in hot/dry SW climates.

16
Increase Quality Installation and Maintenance

• Proposed Strategy
• Stimulate customer demand for quality
  installation and maintenance
• Proposed Actions
• Launch a statewide customer education campaign
• Establish a quality/comfort brand and attach to
  all HVAC installations certified by a third-party

17
Increase Quality Installation and Maintenance

• Proposed Strategy
• Increase Title 24 compliance
• Proposed Actions
• Create market equity for HVAC contractors
• Educate customers, contractors and building
  inspectors on the importance of complying with
  Title 24
• Streamline the permit and inspection process

18
Increase Quality Installation and Maintenance

• Proposed Strategy
• Increase Title 24 compliance (cont.)
• Proposed Actions
• Create Tiered-level rating system to identify
  progressively higher levels of quality
  contractors based on proportion of certified
  technicians
• Establish a progressive green collar
  career/certification path for HVAC technicians

19
Increase Quality Installation and Maintenance

• Proposed Strategy
• Motivate contractors to install systems per
  ACCA/ANSI QI specifications
• Proposed Actions
• Adopt ACCA HVAC QI Specification as CA standard
• Enhance industry and vocational school curriculum
  by integrating QI methods/practices into course
  offerings
• Develop a technician recognition program for
  verified quality work

20
Increase Quality Installation and Maintenance

• Proposed Strategy
• Provide customers and contractors with system
  performance and fault detection feedback
• Proposed Actions
• Establish an open-protocol system allowing
  contractors to download systems diagnostics and
  servicing information
• Provide interconnection point for utility load
  reduction and demand response

21
Increase Quality Installation and Maintenance

• Proposed Strategy
• Provide customers and contractors with system
  performance and fault detection feedback (cont.)
• Proposed Actions
• Stimulate RD in on-board diagnostics
• Stimulate market development of thermostat
  display providing customers with real time
  performance and maintenance information

22
Accelerate Market Penetration of New Equipment
Technologies

• Proposed Strategy
• Develop appropriate and useful energy efficiency
  performance metrics
• Proposed Actions
• Adopt an equipment rating system that accurately
  predicts system performance and energy use in hot
  and dry climates
• Develop a time based performance metric that
  measures and values peak and energy savings from
  an HVAC system giving credit for cooling systems
  that shift energy use to off peak periods

23
Accelerate Market Penetration of New Equipment
Technologies

• Proposed Strategy
• Stimulate High Efficiency systems design research
  
• Proposed Actions
• Create design competitions to reward architect
  and manufacturer teams for designing new homes
  requiring no net electricity from the grid during
  peak periods using a combination of
• passive cooling strategies,
• advanced cooling equipment,
• photovoltaic systems

24
Accelerate Market Penetration of New Equipment
Technologies

• Proposed Strategy
• Adopt innovative regulatory policy changes to
  encourage larger-scale market outcomes
• Proposed Actions
• Estimate energy savings achieved by the HVAC
  quality initiatives at the market rather than the
  program level
• Include spillover and other market effects

25
Local Government Input and Comment

• Is the strategic plan consistent with your local
  government priorities?
• Feedback on proposed strategies to increase code
  compliance
• Feedback on branding and QI recommendations
• Feedback on customer education campaigns
• Programs strategies or approaches that have
  worked to improve HVAC quality of installation at
  the local government level and reduced peak
  energy use for residential or commercial markets.

26
Opportunities for Partnership

• What can we do to find and pursue mutual
  objectives?
• Are we missing other key stakeholders?
• Are there local government reps interested in
  being on a CEC steering committee?
• Where are opportunities for joint funding,
  design, implementation, and such?

27
Next Steps

• Workshop at CEC to gather public comments
• Comments due on CEC strategic plan
• CEC committee approval
• Final strategic plan available
• Strategic plan submitted to legislature
• Integration of CEC plan with IOUs on CPUC
