resources is equal to the value of the energy consumed annually by the building, at the level of a single project.

8 1. ZNE Strategy: the 2015 IPER Vision A decade ago when the ZNE goal was first set it was a simple idea: All newly constructed residential buildings by the year 2020 must be ZNE as defined by the IEPR: the value of the net amount of energy produced by on-site renewable energy resources is equal to the value of the energy consumed annually by the building, at the level of a single project. using the California Energy Commission s Time Dependent Valuation metric. Improving building energy efficiency and deploying PVs were identified as the primary tools to achieve the ZNE goals 8

ZNE Goals Lessons Learned Reality turns out to be more nuanced - Since ZNE policy was first set we have learned about the impact of 50% RPS and large scale PV deployment on the grid large scale

9 ZNE Goals Lessons Learned Reality turns out to be more nuanced - Since ZNE policy was first set we have learned about the impact of 50% RPS and large scale PV deployment on the grid large scale utility deployment of PVs and to a lesser extent building-based PVs lower the value of additional electricity around midday Net energy metering (NEM) and Time-Of-Use (TOU) on compensation for residential customer-owned generation and cost effectiveness of PVs

ZNE Goals Lessons Learned - Continued The current NEM rules treat the grid as virtual storage (or a bank), where the overgenerated kwhs can be stored and retrieved later in the day, or even as

which results in a larger PV array, must be coupled with grid harmonization strategies to realize the expected environmental and home owner benefits Currently, customer-owned storage at about

10 ZNE Goals Lessons Learned - Continued The current NEM rules treat the grid as virtual storage (or a bank), where the overgenerated kwhs can be stored and retrieved later in the day, or even as if summer kwhs could be stored until winter In reality, the grid as it is now has very little capability to store and effectively use overgenerated kwhs from PVs Electrification of homes, which results in a larger PV array, must be coupled with grid harmonization strategies to realize the expected environmental and home owner benefits Currently, customer-owned storage at about $450/kWh is still too expensive to be cost effective using the LCC for the 2019 Standards, but this is a fast evolving technology which can become cost effective under a future cycle of the Standards

ZNE Goals Lessons Learned - Continued The most important lesson is that grid harmonization strategies (GHS) must be coupled with customer owned PV systems to bring maximum benefits to the grid,

11 ZNE Goals Lessons Learned - Continued The most important lesson is that grid harmonization strategies (GHS) must be coupled with customer owned PV systems to bring maximum benefits to the grid, environment, and the home owner GHSs are strategies that maximize self-utilization of the PV array output and minimizes uneconomic exports to the grid, examples of GHS include but not limited to battery storage, demand response, thermal storage, and EV integration. the 2019 Standards approach must consider these issues

12 ZNE Goals 2019 Standards Goals The 2019 Standards should be structured to send the right signal to the market to pave the way for achieving full ZNE in a later cycle of Standards by encouraging: 1. Envelope efficiency, 2. Appropriately sized PVs, and 3. Grid harmonization strategies that maximize self-utilization of the PV output and limit exports to the grid Further, the standards must be framed in a way to encourage competition, innovation, and flexibility to foster new solutions as the grid and technologies evolve. A possible structure is proposed later in the presentation.

The ZNE Challenge: Grid Harmonization Approaching the 50% Renewable Portfolio Standard (RPS) by 2030, and to a lesser extent, increasing customer-owned renewables depress the value of PV generated

13 The ZNE Challenge: Grid Harmonization Approaching the 50% Renewable Portfolio Standard (RPS) by 2030, and to a lesser extent, increasing customer-owned renewables depress the value of PV generated electricity in midday, resulting in the so called Duck Curve issues; this necessitates developing GHS strategies that bring maximum value to the home owner, environment, and the gird. Hawaii and Australia that have already encountered these problems, are adopting grid integration/harmonization strategies to maximize self-utilizations and minimize exports to the grid Recent News Article April 10,

16 PV Cost Effectiveness - Findings All Standards measures, whether efficiency or renewables, must be cost effective in each CZ, using life cycle costing Using the 2019 TDVs which captures the impact of 50% RPS by 2030, the LCC finds: Appropriately sized PVs that displace the site kwh are found to be cost effective in all climate zones, even if the NEM2 rules are changed to compensate hourly exported kwhs at avoided cost, and assuming no Federal ITC

17 Proposed Prescriptive 2019 Standards PV Size Prescriptively, the PV size will be sized to displace the annual site kwhs of the home The prescriptive PV size will be calculated as follows: PV s = W sf X CFA X A aj X CZ aj Where PV s is the DC size of the PV system W sf is the PV size per square foot of the CFAfor a dwelling of 1200 sf or less CFA is the conditioned floor area A aj is the area adjuster CZ aj is the climate zone adjuster There will be look up tables for the area and CZ Adjusters For performance compliance, we ll use the Energy Design Rating (EDR) Tool

Builds on Commission s Energy Design Rating Tool Energy Design Rating (EDR) score show how close a home is to the ZNE target Aligned with RESNET Reference home is a 2006 IECC compliant home, EDR=100

18 Builds on Commission s Energy Design Rating Tool Energy Design Rating (EDR) score show how close a home is to the ZNE target Aligned with RESNET Reference home is a 2006 IECC compliant home, EDR=100 A score of zero means the house is a ZNE building CEC s CBECC-Res software has the capability to calculate EDR scores for EE and PV Builders can use a combination of envelope energy efficiency features, better appliances, PVs, and other strategies to get to the target EDR Download CBECC-Res here for free:

19 Proposed 2019 Standards Approach Energy Design Rating (EDR) targets for each climate zone: 1. An EDR level for energy efficiency features based on 2019 prescriptive measures This EDR target can only be met using energy efficiency measures 2. An EDR Contribution for PV array that is sized to displace the annual site kwhs (no more PV tradeoff) 3. Combine the energy efficiency EDR with the PV EDR for one final target EDR

20 Proposed 2019 Standards Approach 1. Maximize envelope efficiency as allowed by LCC and calculate EE EDR i. HPA to R19 in severe CZs Currently R13 ii. HPW to ~ U-factor in severe CZs Currently iii. Windows U-factor of 0.30 and SHGC of 0.23 Currently 0.32 and 0.25 iv. QII as a prescriptive requirement Establish an Energy Design Rating (EDR) for energy efficiency in each CZ that can only be met with efficiency measures (no PV tradeoff against EE) 2. Calculate EDR of PV array as follows: i. Calculate the PV size required to displace the site kwh in each CZ ii. Calculate the EDR contribution of the PV array 3. Combine the EE EDR contribution with the PV EDR contribution and establish a final EDR in each CZ that the building must meet to comply Note: Examples are presented in later slides

21 Target EDR s Many Advantages 1. A target EDR establishes a performance benchmark that the building must meet to comply; the concept is similar to performance standards consistent with the Warren-Alquist Act expectation to provide builders with compliance flexibility 2. As shown by the 2016 HPA and HPW approach, builders appreciated having many options to comply, leading to a flurry of innovation in attics and walls, which continues to date 3. Target EDR can send the right signals to the market about EE, PV sizing, storage, demand response and flexibility, and other grid harmonization strategies that can achieve ZNE in the future 4. Target EDR allows the builder to use more efficiency and less PV to get to the target; the builder can also use high performance glazing or appliances that are higher than minimum efficiency levels that we are prevented to require because of preemption 5. Target EDR is fully compatible with the reach codes, local jurisdiction simply identify a lower target EDR (or zero) that can be met with a combination of additional EE, PV, demand response/flexibility, EV integration, or storage 6. Target EDR works well with varying building sizes static PV size does not

22 Target EDR Advantages - Example Here is an example of how CBECC-Res calculates the Target EDR for both EE and PV in CZ12 for the 2,700 sf house:

All-Electric Home Option What should be the PV EDR Target be for All-Electric Homes (AEH)? Staff proposes the same PV EDR targets used for mixed fuel homes be used for AEHs: 1.

23 All-Electric Home Option What should be the PV EDR Target be for All-Electric Homes (AEH)? Staff proposes the same PV EDR targets used for mixed fuel homes be used for AEHs: 1. Requiring a much larger PV system on an AEH to displace the larger annual kwh may disincentivize the AEH approach 2. The larger PV needed to displace the AEH kwh, without grid harmonization strategies, can potentially aggravate the duck curve issues Large number of AEHs, due to higher winter kwh usage than summer, can cause a winter peak that may be as large or larger than the summer peak with limited solar resources in the winter to help.

peak and demand in winter Grid harmonization becomes more

24 All-Electric - Summer Duck vs Christmas Turkey All-Electric homes use more kwhs in the winter than summer that may result in higher peak and demand in winter Grid harmonization becomes more important Like a broken clock, a dumb PV systems is correct twice a YEAR
