Why energy efficiency first?

HomeownerSavings – lower energy billComfort – energy efficient, solar homeEnvironment – reduced carbon footprint

Builder/DeveloperDifferentiation from competitionIncentives for both the energy efficiency measures and solar systemEase of access and reduced paperwork

Solar ContractorDifferentiation from competitionCustomer satisfaction

How to achieve higher EE

Strategies vary by climate zone, market sector, and building type

High performance windowsEnergy efficient water heatingImproved wall and ceiling insulationHigh efficiency space heating and cooling equipment (HVAC)High efficiency appliancesHigh Efficacy lightingProperly sized equipment

Case Study – Carsten Crossings*70% electrical offset – 2.5 kW PV system35% above 2005 Title 24, 40% reduction in coolingBuilding Envelope

R-49 attic insulation R-15 blown insulation wallsWindows: U-value .35 & SHGC .32

Mechanical SystemTankless water heaters .84 EF94 AFUE furnace variable speedAC: 15 SEER/12 EERVentilation – Beutler Fresh VentENERGY STAR appliancesHERS Measures – buried ducts, high EER right sized AC, duct testing, thermal bypass checklist, house wrap/blower door

RNC - How to Participate

Work with your Title 24 consultant to decide on the best combination of measures for the program that fits your budgetComplete the application and appropriate form online or work with your PG&E representative

You will need: Title 24 information for each of the plan types in your projectHERS Provider and contact information for the specific HERS rater who will be performing the field verification and testing

1212

RNC - Required Documents

Required documentationHard copy of the final 2005 CA Title 24* CF-1R and/or CF-1R-PV form as filed for your building permitElectronic input file for CF-1R and/or CF-1R-PV compliance computer run for each model as approved for the project’s building permit Complete set of construction plans:

Floor plan with elevations and electric planSite plan with North arrow for custom homes Mechanical, electrical, and floor elevation plansSubdivision lot map and list of lots/addresses for production home projects

*2008 Title 24 in effect August 1, 2009

1313

Required Documents (Cont’d)

Copy of the signed EPA Partnership Agreement for all ENERGY STAR projects (if ES)Manufacturer equipment specification documentation (ARI/GAMA listings) to ensure proposed equipment meets program requirements and matches efficiency levels specified in the Title 24 documents

1414

Title 24Title 24, Part 6 – Energy Efficiency Standard

New 2008 Standards effective August 1, 2009Methodology

Mandatory MeasuresPrescriptive Method (list of requirements) Performance Approach (trade off between features, flexible budget)

Performance ApproachUsed to analyze the building’s performance above codeEmphasis on peak reduction (Time Dependent Valuation)

15

Title -24 (Cont’d)

Certified software programsEnergy Pro (Versions 4.1, 4.2, 4.3, 4.4)Micropas 7 (Versions 7.0, 7.1, 7.2, 7.3)

Programs compare “Standard Design” with the “Proposed Design”

Compliance Margin – the difference between the two

Third Party Plan CheckThird Party Field Verification

Plan Check

Applicant submits compliance documentation and selects HERS raterThird party plan check

Verify completeness and accuracy of Title 24 documentationValidate energy savings and compliance margin

17

HERS Verification

HERS Provider – CalCERTS, CHEERS

HERS Rater – performs field verification and diagnostic testingHERS Rater inspects all EE measures that helped achieve 15% margin

Energy saving not realized unless measures are installed properlyHERS Rater inspects PV system

Verify system design and installation (site-specific or California Flexible Installation)Confirm shading, azimuth, and tiltVerify performance – solar irradiance, ambient temperature, AC output displayed on inverter (expected output measured by PV calcs)
