  2. 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!

  3. Sierra Club Energy Quiz cont’d. 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

  4. Sierra Club Energy Quiz cont’d. 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.

  5. Sierra Club Energy Quiz cont’d. 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.

  6. Sierra Club Energy Quiz cont’d. 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 you’ve 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.

  7. The Sierra Club Quiz Answers… C, B, A, C, B respectively… C. YOU - 10 CFL’s…$92/$582. You'll also reduce carbon dioxide emissions by 1,431 lbs. a year, and 7,155 lbs. in five years. B. Everyone – 10 CFL’s …and save 81 million tons of CO2 entering the air. That's like taking 15 million cars off the road. A. Clothesline vs. dryer…$80/$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.

  8. 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 • 1967 – California Air Resources Board established • 1971 – CARB automotive NOx standards • 1978 – No new nuclear power without permanent storage • 1977 – Building and Appliance efficiency standards created with provisions for updates every three years • 1982 – IOU rates of return decoupled from volumes; utility efficiency incentive programs established • 1991 – CARB establishes specifications and properties of reformulated, low emission gasoline. • 1996 – PUC recommends electricity deregulation plan. • 1997 – SB 90 deregulates IOUs and creates Public Interest Energy • Research (PIER) program. • 2003 – The CPUC and the CEC establish “the Loading Order” following 2001 Deliverability 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

  15. Non Res CEC Approved Software • Energy Pro • Perform • eQuest/D2Comply It’s 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 (< 3 stories)

  17. Res CEC Approved Software • Energy Pro • Micropas 7 It’s 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.

  18. 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. http://www.energy.ca.gov/maps/CLIMATE_ZONES.PDF

  19. 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.

  24. 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 and specify the best possible materials, 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/default.htm (accessed May 15, 2008) will provide additional detail.

  26. CHEERS Rater • CHEERS Rater – A rater of systems and elements in the California Home Energy Efficiency Rating Service (CHEERS) new construction Quality Assurance program who has completed training curriculum that was approved by the California Energy Commission. For both HERS, and CHEERS raters, see also http://www.energy.ca.gov/HERS/notices/2006-04-28_provider_approval.html, a notice regarding the proper provider service approved by the CEC. CAD Drafter/Designer • Prepares drawings from which volume and area data may be extracted from objects and schedules for use in building energy simulation software in quantification of spaces, wall areas, window areas and types of assemblies and building elements.

  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/
