2008 Building Energy Standards

Effective date: January 1, 2010

Some cities and counties will allow you to submit 2008 Title‐24 compliance calculations prior to January 1, 2010.Benefits of using 2008 Standards now (tract projects)


Current projects that might slip past January1 date should be analyzed using 2008 Standards to avoid surprises later.


Effective date: January 1, 2010



Brief History of Title‐24

1976 California Energy Commission created1977 Warren‐Alquist Act“The standards shall be cost effective”


ff“C.E.C. shall periodically update the standards and adopt revisions when deemed necessary”

Brief History of Title‐24 1978 thru 1998 Title‐24 fairly low priority concern in plancheck process2001 Standards changed all thatTighter code/HERS Measures/City Requirements have made Title‐24 a priority best addressed early in design stageUtility Incentive Programs also use Title‐24 as yardstick to qualify submittals into their programs


submittals into their programs.2008 bottom line:

Title‐24 needs to be incorporated early into the building design processTitle‐24 is not over when permit is issuedAll in design team need to be well versed in Title‐24 requirements, HERS measures, forms and inspections, coordination is critical.


Brief History of Title‐24 Compliance forms have grown exponentially

HVAC


SEER vs EER

Questions:


What is the difference between EER and SEER?

Why does it matter?

HVAC


SEER vs EER

EER is measured at 80 degrees indoor air running continuously


indoor air running continuously

SEER is measured by using the EER and factoring in the same unit running under a lighter load (80 degrees indoor, 82 degrees outdoor and cycling on and off

HVAC


SEER vs EER

Why this matters:

Possible for two units with the same


SEER to have different EERs

For two units with a given SEER the one with the higher EER will be more efficient

EER’s higher than 10 require HERS verification

Take time to verify SEER and EER

10/1/2009

20

HVAC


SEER vs EER

Why this matters:

EER higher than 10 will trigger a


g ggHERS credit in the Title-24 compliance calculations

Will also appear on the CF-1R as a HERS measure required verification and a CF-4R

HVAC


SEER vs EER

Bottom Line:Minimum efficiency levels remain


Minimum efficiency levels remain essentially unchanged from 2005 standards. EER more important

HVAC Equipment Sizing


Heating

The Standards do not set limits on the sizing of heating equipment, but they do require that heating loads be calculated for new heating systems Acceptable load calculation procedures include methods described in the ASHRAE Handbook –Equipment, ASHRAE Handbook – Applications, ASHRAE Handbook –Fundamentals, SMACNA Residential Comfort System Installation Manual, or ACCA Manual J.”

HVAC Equipment Sizing

Cooling


Cooling

“Just as for heating equipment, the Standards do not set limits on the size ofcooling equipment, but they do require that cooling loads be calculated for newcooling systems. Avoiding over sizing is especially important for coolingequipment because efficiency degrades when the system cycles on and offfrequently.

The Standards offer a compliance credit when the installed air conditioningequipment is sized in accordance with the Reference Residential Appendix RA1Maximum Rated Cooling Capacity for compliance credit sizing calculations. AHERS rater field verification is required to confirm that the installed equipmentconforms to the sizing criteria as reported on the CF-1R.”

Bottom Line for 2008

Building designs that generate high heating/cooling loads during peak t i d ill b l li d


energy cost periods will be severely penalized

Electric multipliers for 2008 up to 50 verses 20 in 2005 standards

Gas multipliers for 2008 up to 1.5 vs. 1.0 in 2005 standards

Upside: Energy saving features, strategies that reduce peak loads are rewarded greatly

Ventilation


ASHRAE 62.2-2007

What is a sone?


8

A Sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the sonevalue, the more comfortable the listening environment. Sones are not decibels or volume, but rather how sound is "sensed". One sone is the equivalent of a quiet refrigerator.

First proposed by Stanley Smith Stevens in 1936.

Also will need to review CF-1R during bid process to determine if any HERS measures will affect their work



work

Will require coordination between Designer, Title-24 consultant and HERS raters

CF-6R forms filled out by hand will be unwieldy because of requirements to file electronically

CF‐4R Field Verification/HERSRegistration

y g

Can use services of HERS raters to facilitate transmittal of CF-6R to registry. However contractor is responsible for content of CF-6R and must sign. HERS rater cannot certify information on a CF-6R form.

The days of filling out CF-6R on the hood of contractors work truck are basically over

Good communication and record keeping criticalUse time left to put into place filing system/record keeping system

Architects/Designers2

Set up drawing files to accept all forms required on plans


Set up note blocks for ASHRAE 62.2 requirements

Window selection cannot be put off until building under construction. Using default U-factors/SHGC for plan-check submittals will make it difficult if not impossible to comply.

Bring Title-24 consultant on board early in design stage


HVAC Contractors3

Be prepared to perform rough-in duct testing (4% leakage)HERS rater can do this for you

Provide training to your installers for proper duct sealing, airflow, refrigerant charge to minimize HERS verification failures

Prepare proper load calcs for every job and have documentation ready


Prepare proper load calcs for every job and have documentation ready.

Will need system for providing access holes and labeling to avoid holdups in HERS verifications

Be prepared to fill out electronically CF-6R for HVAC new and change-outs

Develop system to record and track CF-6R forms that will be needed later in HERS process or incentive process

Develop good relationship with local HERS rater(s) HERS rater cannot be part of your company in any way shape or form, cannot self-verify. HERS raters are audited annually.


Building Officials4

Download Standards, Manual, Appendixeshttp://www.energy.ca.gov/title24/2008standards/index.html

Building departments will need to set up access to HERS provider data registry.

Understand which documents required at plan-check and which are required at inspection (CF-1R CF-6R kitchen lighting CF-4R)


1R, CF-6R, kitchen lighting, CF-4R)

Forms are much more data intensive. Get familiar with new layout of forms and all the data that is now required.

HERS measures now baseline. Submittals that comply without them should be reviewed closely.

Inspectors will need to be familiar with all of the CF-6R forms.If registration required must be registered CF-6R forms, not filled out by hand.

Training on ASHRAE 62.2 highly recommended. Become familiar with ventilation calculation methods fan/control features that satisfy this requirement. Important for on-site building inspector, not at plancheck.
