Benefits of using 2008 Standards now (tract projects)

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

Brief History of Title-24 1978 thru 1998 Title-24 fairly low priority concern in plancheck process

2001 Standards changed all that

Tighter code/HERS Measures/City Requirements have made Title-24 apriority best addressed early in design stage

Utility Incentive Programs also use Title-24 as yardstick to qualifysubmittals into their programs.

2008 bottom l ine:

Title-24 needs to be incorporated early into the building design process

Title-24 is not over when permit is issued

All 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

SEER vs EER

Why this matters:

Possible for two units with the sameSEER to have different EERs

For two units with a given SEER theone with the higher EER will be moreefficient

EERs higher than 10 require HERSverification

Take time to verify SEER andEER


HVAC

Heating

The Standards do not set limits on the si zing of heating equipment, but they do

require that heating loads be calculated for new heating systems Acceptable loadcalculation procedures include methods described in the ASHRAE Handbook

HVAC Equipment Sizing

Cooling

Just as for heating equipment, the Standards do not set l imits 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 cyc les 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 install ed equipmentconforms to the sizing criteria as reported on the CF-1R.

Bottom line

Will require good coordination with HERS rater for all three HERS HVACmeasures. Choice: Invasive (gauges) or non-invasive.

HVAC contractors will need to become familiar with testing procedure forall 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 andpressure 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.

Bottom Line for 2008

Building designs that generate high heating/cooling loads during peakenergy 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 loadsare rewarded greatly

CF-6R bottom line:

CF-6R forms a major part of Title-24 compliance now. Thereal teeth in the new code.

Contractors need to be familiar with CF-6R forms and haveinformation gathered to fill out form.

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

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

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

Will need a system to provide documentation package toinspector, HERS rater, & homeowner & registry if necessary

Implications:

If registration required building department will requireregisteredcopies of CF-1R , CF-6R, and CF-4R thatdisplay their unique registration number

Contractors may not be set up to submit their CF-6R formselectronically for registration

Can use services of HERS raters to facilitate transmittal ofCF-6R to registry. However contractor is responsible forcontent of CF-6R and must sign. HERS rater cannotcertify information on a CF-6R form.

The days of filling out CF-6R on the hood of contractors

work truck are basically over

Preparation for 1/1/2009

Architects/Designers2

Set up drawing files to accept all forms required on plans

Set up note blocks for ASHRAE 62.2 requirements

Requirement for load calcs should be part of HVAC bid-spec

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

Bring Title-24 consultant on board early in design stage
