Beyond Title-24
How do you get beyond Title-24? Challenges: New 2008 Title-24 Building Energy Standards 15-22% more
restrictive, tougher than current 2005 energy code. Many energy credits in 2005 standards are now baseline for 2008
energy code New 2008 energy code introduces additional layers of compliance
criteria, forms, paperwork

Beyond Title-24
How do you get beyond Title-24? Opportunities: 35% better than 2005 Title-24 has been achievable. 2008 Title-24 energy code contains new credits Building industry has reacted to carrots and sticks

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.

What is the difference between EER and SEER?
Why does it matter?
www.energycode.com www.energycode.com
HVAC
Minimum AFUE, SEER, EER
SEER vs EER
EER is measured at 80 degrees 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
www.energycode.com www.energycode.com
HVAC
Minimum AFUE, SEER, EER
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
www.energycode.com www.energycode.com
HVAC
Minimum AFUE, SEER, EER
SEER vs EER
Why this matters:
EER higher than 10 will trigger a HERS credit in the Title-24 compliance calculations
Will also appear on the CF-1R as a HERS measure required verification and a CF-4R

Bottom line
These HERS measures are baseline in Package D so they will be widespread
Because they are required in Package D they are not available as a credit to help you go beyond Title-24
HVAC contractors will need to become familiar with testing procedure for all three HERS measures.
CF-6R HVAC forms will need to be filled out prior to HERS verification tests
Will need system in place for providing sensors, temperature and pressure access holes w/labels for HERS raters

New for 2008 Residential Standards
Previous versions of Title-24 did not account for time-of-use patternsTDV accounts for variations in cost related to time of day, seasons, geography, fuel type2008 Standards now places a higher value on energy savings during high cost timesEncourages designs that will reduce peak loads thru-out California.

Model each window and door separately in compliance run
Utilize exterior shading devices
No credit for interior shading devices

Impact of Time Dependant Valuation (TDV) 4
Bottom Line for 2008
Building designs that generate high heating/cooling loads during peak 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, can help you go “better than” Title-24

Bottom line
HERS measures represent one of the most cost-effective energy savings strategies in the energy code.

CF-6R bottom line:
CF-6R forms a major part of Title-24 compliance now. The real “teeth” in the new code.
Contractors need to be familiar with CF-6R forms
Also will need to review CF-1R during bid process to determine if any HERS measures will affect their 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
Will need a system to provide documentation package to homeowner:

Implications:
If registration required building department will require registered copies of CF-1R , CF-6R, and CF-4R that display their unique registration number
Contractors may not be set up to submit their CF-6R forms electronically for registration
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

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.

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)
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.
