CAHP-ZNE: 2017 Program Update*

Transcription

1 California Advanced Homes Program CAHP-ZNE: 2017 Program Update* For launch January 1, 2017 *For homes permitted to the 2016-Code Single Family program only Program details as of 8/23/2016 Program design may change

2 Agenda 1. Program update overview 2. Energy Design Rating (EDR) as the new program metric 3. Bifurcation between coastal and inland climate zones 4. Program kickers 5. Program eligibility and incentive charts 6. Implementation details

3 2017 Program Update Overview With the 2016 Code, CAHP will update its program requirements, incentive schedule, and program mechanics for the new code. Operating with the same structure as during the 2013 Code Supporting Zero Net Energy (ZNE) as defined in Title 24, using TDV energy Switching from CAHP Score to Energy Design Rating (EDR) Using different entry scores for coastal vs. inland climate zones Updating kicker options and mechanisms Applicable to all 2016 Code permitted homes, starting 1/1/17

4 2017 Program Redesign Goals Focus on 2019 Code and thus 2020 Res ZNE goal Efficiency first, then ZNE through PV solar Continue using a whole-house efficiency metric (EDR) Emphasize and support challenging measures: HPA, HPW, etc. Add non-regulated load reduction measures (i.e., HEMS (plug loads), ESTAR white goods (appliances), 100% LED (lighting) Reward best practices: DOE-ZER, balanced ventilation Maintain conceptual continuity with 2013-Code program for ease of participation 4

5 EDR vs. CAHP Score Same in EDR and CAHP Score Design a home Model with CEC software Generate score of 0 to 250 Both use TDV Both use T24 ruleset Difference between EDR and CAHP Score The reference home used to define a score of 100 CAHP Score = 2008 Title 24 EDR = 2006 IECC (equivalent to RESNET HERS) Reference Home Score of 100 CAHP EDR 5

6 Energy Design Rating (EDR) Currently modelable in CBECC-Res 2016 and EnergyPro 7.0 Roughly aligned with the RESNET HERS Score Based on TDV Energy and includes all end uses in the home Will base core incentives on the EDR before applying solar Will award ZNE kickers for an EDR of zero (a CA Code ZNE home) 6

7 Coastal Group and Inland Group Different entry scores for coastal and inland climate zones Coastal = CZ 1-7 & 16 Inland = CZ

8 Four Types of Program Kickers 1. ZNE Kickers 2. EDR Performance embedded Energy reductions are calculated in TDV, and given via a reduced EDR commensurate to savings 3. Bonus cash kickers Green, or non-modeled measures that don t lead to direct energy reductions (e.g. DOE-Zero Energy Ready) 4. Hybrid Measures that have performance embedded savings AND a cash kicker to emphasize import (e.g. High Performance Attics) 8

9 Bonus Amount Note Program Kickers Preview Designed for 2020 ZNE $1,000 Design EDR below entry; Final EDR of zero once installed solar is applied Designed 2020 ZNE Ready $500 No solar installed. Designed with a solar ready zone, and a Design EDR low enough that a 3kW panel would lead to Code ZNE. High Performance Attic/DCS $200 + EDR Hybrid High R-Value Walls $200 + EDR Hybrid Whole House Fan $100 + EDR Hybrid Balanced IAQ ventilation $100 Cash bonus DOE-Zero Energy Ready home participant $400 Cash bonus All ESTAR white goods ~ 2-3 pts EDR Performance measure not yet fully specified HEMS ~ 1-2 pts EDR Performance measure not yet fully specified 100% LED Lighting ~0-1 pt EDR Performance 9

Home Energy Management System 1-2 EDR Points est. 100% LED 0-1 EDR Points est. ZNE Achieved Incentive Designed for 2020 ZNE $1,000 *For any project installing sufficient PV to offset all TDV energy use. Achieved for the coastal climate zones for most homes under 48. High Performance Attic $200 High Performance Walls $200 Whole House Fans $100 Balanced IAQ $100 DOE Zero Energy Ready $400 10

11 Incentive Curve Inland Group Maximum incentive ZNE incentive Minimum entry EDR = 44 - $500 Potential cash kickers Core incentive Proposed Incentives Structure - Inland Group Entry EDR score 44 Entry incentive $500 Per-point incentive from $150 Inflection EDR Score 40 Per-point incentive below 40 $300 Performance Embedded kickers All ENERGY STAR appliances 2-3 EDR Points est. Home Energy Management System 1-2 EDR Points est. 100% LED 0-1 EDR Points est. ZNE Achieved Incentive Designed for 2020 ZNE $1,000 *For any project installing sufficient PV to offset all TDV energy use. Achieved for the coastal climate zones for most homes under 48. High Performance Attic $200 High Performance Walls $200 Whole House Fans $100 Balanced IAQ $100 DOE Zero Energy Ready $400 11

12 Program Implementation Details Program eligibility applied at Plan level rather than Project level Each production plan must achieve an EDR below the entry threshold in all 4 orientations. Projects may build plans that fail to comply. Homes built with those plans are not eligible for incentives PV Offset is not possible as part of the EDR calculation PV is only applied for the Designed for 2020 ZNE kicker (e.g. EDR 0 after solar is applied) Homes may use the PV Offset for Title 24 compliance Permit-to-program rule applies Heat pump water heater and space heater systems do not yield accurate EDR calculations in current software 21 12
