Title: HVAC Strategic Plan


1
HVAC Strategic Plan
  • Mission Statement-The HVAC working group will
    develop a suite of strategies to reduce the
    energy and peak use associated with the design,
    selection, installation, and maintenance of new
    central air conditioning systems and recommend
    demonstrations or tests for some or all of these
    strategies . The results of its initial work will
    be included in the CECs strategic plan to the
    Legislature and provided to the CPUC and its
    utilities to help guide their strategic planning
    process. .

Trends in Residential and Small Commercial AC
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.

3
Californias Air Conditioning Demand
  • Residential AC installed in new homes has
    increased from 25 in 1976 to 95 in 2007.
  • Home sizes have increased by 55 from 1,560 sq.
    feet to 2,390 sq. feet.
  • 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.

Figure 1
Since 1976, Residential AC growth in new homes
has increased from 25 to over 95 in 2007.

AC Appliance Standards
  • The energy efficiency SEER ratings for AC units
    went from 7.0 SEER in 1977 to 13.0 SEER in 2006.
  • This means that energy usage requirements for the
    same sized AC unit were reduced by 80 over 30
    years, if SEER ratings were directly
    transferrable 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 the demand.

6
Since 1976 the share of peak demand associated
with residential AC has grown from 6 of total
peak demand in 1976 to roughly 24 in 2007.
7
The HVAC Problem
  • Customers are not used to asking for or
    recognizing quality installations for HVAC
    installations
  • Installation Quality is poor for new or
    replacement CAC systems
  • 90 to 95 of HVAC installations have not pulled
    permits
  • When permits are pulled, inspections show that 30
    to 50 of the installations are done improperly
    due to
  • Failure to set air flow refrigerant charge to
    manufacturer specs
  • Lack of proper HVAC system sizing..
  • Bigger is not necessarily better or necessary.
  • Standards Requirement to test and seal ducts are
    often ignored.
  • Major lack of trained technicians, contractors
    and inspectors.
  • Cooling Equipment parameters are not optimized
    for Western Climates
  • National Standard set to 82, mild and humid
    temperatures

8
Setting Two High Level Goals for the Unitary Air
Conditioning Market
  • Goal 1- Increase the Quality of Installation and
    maintenance of Central Air Conditioning Systems
    to achieve additional energy and peak savings
    relative to the status quo ( residential and
    small commercial markets)
  • Goal 2- Accelerate the market penetration of new
    hybrid DX systems that are more energy and
    peak1 efficient than existing equipment
  • 1 Peak efficient means that the cooling system
    requires less power and energy use from noon to 8
    pm to meet typical customers cooling needs

9
Strategies to meet Goal 1- Increase installation
quality and maintenance
  • Strategy 1-Increase customer demand for evidence
    of quality control at the time of HVAC
    installations through a customer education
    campaign and the introduction of a
    quality/comfort brand that will be placed on all
    HVAC equipment that has been certified by a third
    party.

10
Strategy 2
  • Create a level playing field in the HVAC
    installation market by increasing the probability
    that building permits will actually be pulled for
    all replacement jobs, reducing the cost of
    pulling permits, and ensuring verification
    information is used in a constructive manner by
    all parties-
  • This will require the introduction of a new
    compliance system designed to track the status of
    HVAC equipment from the sale to contractors at
    the distributor office to the final quality check
    performed by third parties in the field.

11
Strategy 3
  • Motivated technicians- Increase the number of
    trained technicians qualified to perform a HVAC
    system installations that meet ACCA
    specifications and motivated to receive
    recognition for verified quality work. This will
    require working with existing industry training
    courses and the vocational schools in California
    that may need to provide new quality control
    courses.

12
Strategy 4
  • Provide systems performance data and fault
    detection feedback to new HVAC customers who opt
    for this service and to their contractors that
    will provide contractors to allow them to build
    a high quality reputation and later to charge
    premium prices for providing higher quality
    services.

13
Strategy 5
  • Create an industry recognized quality brand that
    certifies that the system operating parameters
    necessary for a quality installation have been
    verified This brand can be used in combination
    with utility programs to reward customers who ask
    for quality information and or a quality
    certification check.

14
Strategy 6
  • Create tier levels to identify progressively
    higher levels of quality contractors based on the
    proportion of technicians in a given firm meeting
    NATE or other certifications

15
Strategies to Achieve Goal 2- Installation of
higher efficiency CAC systems after 2011
  • Strategy 7. Develop new energy efficiency
    indicators to rate the expected performance and
    energy use of central cooling systems installed
    in California that more accurately predict system
    power demands in the hot and dry climates of the
    southwest-
  • Strategy 8. Develop a new time based performance
    metric that measures and values both the expected
    from which market based incentives to install
    this new equipment can develop.

16
Strategy 9
  • Stimulate existing research to integrate on board
    diagnostic equipment into new central air
    conditioning systems and provide cash incentives
    to the first 10 of manufacturers who
    successfully integrate and sell on board
    diagnostics as part of their systems by the year
    2009.

17
Strategy 10
  • Adopt policy changes designed to encourage
    utilities to achieve larger scale market outcomes
    by estimating the energy savings achieved by the
    HVAC quality initiatives proposed in this report
    at the market rather than the program level.
    Includes measurement of spillover and other
    market effects. Not just a program focus.

18
Strategy 11
  • Develop and implement design competitions to
    reward architect and manufacturer teams that can
    build new homes that require no net electricity
    from the grid during peak periods using a
    combination of passive cooling strategies,
    advanced cooling equipment and photovoltaic
    systems. (Longer term)
