First, you might say, Why Energy Studies? To
answer that, take this short Sierra Club Energy
Quiz.

• 1. You spend 40 to replace 10 incandescent bulbs
  with CFLs. How much will you save in electricity
  in one year? In five years?
• one year 26, five years 164
• one year 48, five years 304
• one year 92, five years 582
• Ten bulbs? I read with my headlamp and wake with
  the sun!

Sierra Club Energy Quiz contd.

• 2. If all U.S. households in the United States
  replaced 10 incandescents with CFLs, how much
  money and CO2 would we save in one year?
• 1.2 billion and 500,000 tons of CO2
• 10.4 billion and 81 million tons of CO2
• 25.6 billion and 50 billion tons of CO2
• Enough to light our way to a clean energy future

Sierra Club Energy Quiz contd.

• 3. You spend 10-20 on a clothesline or rack and
  hang your clothes to dry in the sun. How much
  will you save in energy costs?
• one year 80, five years 508
• one year 40, five years 254
• one year 110, five years 698
• Hang them? I put them on wet and take a walk in
  the sun.

Sierra Club Energy Quiz contd.

• 4. Most modern electronics in your house today
  don't completely shut off when you press the off
  button on your remote, but go into "standby
  mode." How much does standby mode cost Americans
  each year?
• 400,000
• 4,000,000
• 4,000,000,000
• I'm unplugging all my electronics right now.

Sierra Club Energy Quiz contd.

• 5. You buy a new hybrid for 23,000 instead of a
  sedan that cost 19,000 and gets 22.5 miles per
  gallon. How long before youve recouped your
  additional costs?
• 3.4 years
• 5.3 years
• 7.1 years
• Doesn't matter. I'd buy a hybrid even if there
  weren't a payback.

The Sierra Club Quiz Answers

• C, B, A, C, B respectively
• C. YOU - 10 CFLs92/582. You'll also reduce
  carbon dioxide emissions by 1,431 lbs. a year,
  and 7,155 lbs. in five years.
• B. Everyone 10 CFLs and save 81 million tons
  of CO2 entering the air. That's like taking 15
  million cars off the road.
• A. Clothesline vs. dryer80/508, plus reduce
  carbon dioxide emissions by 1,247 lbs. a year,
  and 6,235 lbs. in five years.
• C. Standby mode accounts for 5 percent of all
  energy use in the United States or
  4,000,000,000.
• B. 5.3 years, but this doesn't count any possible
  tax credit or carpool lane perks.

More Reasons for Energy Studies?

• Though accounting for only 5 percent of the
  world's population, Americans consume 26 percent
  of the world's energy. (American Almanac)
• The final depletion of petroleum reserves is
  likely within this century.
• CA Energy Efficiency Standards for Residential
  and Nonresidential Buildings were established in
  1977 - 1978
• Global Warming results are tied directly to
  energy use as studied by CEC 1988 on
• We need clean, efficient energy, more than ever
  as our consumption is still increasing 5 per
  year!

9
Title 24

• Focus on - Title 24 Standards
• First implemented in California in 1977
• Response to manage rising costs for energy
• Later stepped up in response to challenge of
  Global Warming
• California has led our country in these
  standards, but other countries have also
  implemented standards

10
Timeline for CA and Energy Regulations

  crisis. Deliver on new demand with 1) Efficiency
  and Demand Response, 2) Renewables, and 3) Clean
  Fossil Generation and Distributed Generation.
  Renewables Portfolio Standard enacted.
• 2005 PUC orders 2.2B, 3 year Efficiency
  procurement for the
• IOUs.

11
What exactly is Title 24?

• An energy standard overseen by the Calif. Energy
  Commission
• The Standard covers new buildings and new
  portions of existing buildings
• The Standard requirements are enforced by local
  building departments through the permit process
• The Standard is updated every 3 years
• It has different requirements for Residential and
  Nonresidential applications
• Requirements for compliance vary by Climate Zone
• 2 paths for compliance Prescriptive
  Performance

12
Current T24 2005 Standards

• 2005 Standards - Went into effect October 1,
  2005, and superseded the 2001 Standards. Projects
  that apply for a building permit on or after this
  date must comply with the 2005 Standards.
• Outdoor Lighting Zones
• Adopted Amendments, Cool Roof Coatings
  Performance Requirements, Effective September 11,
  2006.

13
2008 T24 will be in effect 7-1-09

• 2008 Standards Rulemaking - The 2008 rulemaking
  process has been completed.
• The Energy Commission adopted the 2008 Standards
  on April 23, 2008, and the Building Standards
  Commission approved them for publication on
  September 11, 2008.
• These new Standards will be in effect as of JULY
  1, 2009. The requirement for when the 2008
  Standards must be followed is dependent on when
  the application for the building permit is
  submitted. If the application is submitted after
  7/1/09, the 2008 Standards must be met

14
Non-Residential Title 24

• Offices
• Retail, wholesale, grocery stores
• Restaurants
• Hotels, motels
• Assembly, conference areas,
• Industrial work buildings
• Schools, churches, theaters
• Multi-family buildings equal or greater than 3
  stories

• eQuest/D2Comply
• Its worth noting that only eQuest/D2 Comply is
  free at this time of writing.

16
Residential Title 24

• ?? Single family dwellings (any height)
• ?? Duplex dwellings (any height)
• ?? Multi-family dwellings (lt 3 stories)

17
Res CEC Approved Software

• Energy Pro
• Micropas 7
• Its worth noting that none of the approved
  software is free at the time of this writing even
  thought the CALRes software, used in the former
  residential T24 2001 Standard was available from
  the CEC free of charge.

Climate Zones

• Climate zones

The link below goes to a California Energy
Commission (CEC) listing of the climate zones
associated with several thousand specific
California cities, towns and other locations.
This information represents an abridged version
of the CEC publication California Climate Zone
Descriptions, which contains detailed survey
definitions of the sixteen climate zones depicted
in the map image to the right.

T24 Components

• Building Envelope
• roof
• windows skylights doors
• wall assemblies
• floor assemblies
• HVAC Mechanical
• systems including controls
• elements individual equipment components
• Lighting
• indoor
• outdoor

20
Prescriptive Compliance

• Exacting specifications must be followed to
  comply with prescriptive requirements
• Several packages are possible to use
• Appropriate forms and mandatory measures are
  still required to be incorporated into the
  construction documents for projects that comply
  with prescriptive packages

21
Performance Compliance

• This method of Compliance requires calculations
  to show alternative measures that meet the Energy
  Standard comply with the requirements of the
  standard.
• Computer software can be used to model the
  building components, where, exceeding
  requirements in one area, may offset deficiencies
  in another area. A higher insulation value in the
  roof component might allow less insulation in
  walls for example.

22
Who Performs Energy Calculations?

• Anyone with training to do so, can, at present,
  set themselves to the task of using the software
  to perform energy calculations.
• A non-profit org created a Certification Exam,
  but it is not required by the CEC or other public
  agencies.

23
The Certified Energy Plans Examiner, (CEPE)

• The California Association of Building Energy
  Consultants (CABEC), is a private non profit
  organization formed in 1986 to foster
  professional development and ethics in the field
  of energy compliance through sponsorship of
  educational programs for industry professionals
  on building energy efficiency.
  http//www.cabec.org/aboutcabec.php, accessed
  5-01-08.
• CABEC writes and administers two exams, one for
  residential and one for non-residential projects.
  
• The exam for Certified Energy Plans Examiner
  (CEPE), while not required to perform energy
  calculations, does give public agencies and
  employers some assurance that persons who have
  passed it would be well versed in the information
  and able to apply their knowledge properly to
  projects using the current Title 24 Standards.
• Exam locations are offered in Northern and
  Southern California.

Careers

• Energy Auditor Individual who assesses energy
  use in existing projects based on source energy
  providing data from which equipment selection or
  replacement, time of usage decisions, and similar
  decisions to save energy and energy costs may be
  made.
• Energy Analyst performs a variety of energy
  related tasks in private or public practice
• Energy Consultant Firm or individual generally
  hired to advise and to perform measurements and
  calculations of energy use for a client in order
  to be able to save the client money in a
  construction or updating project help to select

  equipment, systems, and forecast life cycle
  costs. May be primarily hired to provide Title
  24 calculations to demonstrate specific project
  compliance.
• Building Department Inspector inspects and
  checks drawings, inspects projects, may perform
  inspection tests or require them

25
HERS Rater

• HERS Rater The Energy Commission has a process
  for certifying Home Energy Rating System (HERS)
  raters who perform third-party inspections when
  verification of duct sealing, thermostatic
  expansion valves (TXVs), refrigerant charge,
  airflow measurement, and building envelope
  sealing measures are used when complying with the
  2005 Standards (effective October 1, 2005).
  Testing and verification protocols are summarized
  and located in both the Residential and
  Nonresidential Field Verification and Diagnostic
  Testing Regulations Manuals. http//www.energy.ca.
  gov/HERS/ (accessed May 15, 2008). Training
  curriculum must be approved by the California
  Energy Commission. Details of coursework can be
  seen at http//www.resnet.us/rater/certified/defau

27
California Energy Commission

• The CEC has updated their website to include much
  more information than previously was available
  regarding T24 Compliance and to provide general
  energy issues information for the public. T24
  training, an Energy Hotline phone number, and
  much more regarding anything overseen by the CEC
  can be explored starting at this root link to all
  T24 information. http//www.energy.ca.gov/title24/
