5 DNV GL © 2013 February 12, 2014 High Level Overview of Measures and Programs Evaluated Upstream HVAC – Incentives to Participating Distributors to Stock High Efficiency – Savings –DEER values with assumptions on building type and vintage – Commercial – Long standing program, Majority of market participating – Residential – Pilot program for Quality Installation (QI) – Incentives to exceed Title 24 change out requirements – Savings – Workpapers – To code – Pilot program for Quality Maintenance (QM) – Incentives for maintenance to improve existing system efficiency – Savings – Workpapers, some DEER measures for local/3 rd party Deemed HVAC– Multiple HVAC measures in commercial, residential, and other programs, Prescriptive rebates for HVAC equipment, primarily DEER savings Lab testing and Market Assessment support evaluations of all measures; They also can inform ex ante assumptions in workpapers and DEER 5

6 DNV GL © 2013 February 12, 2014 High Priority Activities Based on ESPI Measures Evaluability Assessment for Mini-splits – Part of Upstream HVAC Evaluation Field Assessments for Quality Maintenance – Part of QM Evaluation, Multiple Methods under Consideration Continue Laboratory Testing from – Informs QM, Key to linking field measurements to savings estimates in workpapers and DEER for multiple HVAC measures 6

7 DNV GL © 2013 February 12, 2014 Roadmap Summary Approached Updating the Roadmap by – Updating assumptions on studies – Reviewed planned activities and listed potential challenges or issues – Developed a Proposed Approach to specifically overcome the challenges or issues identified that may complicate a given study – Example: – The solution proposed for this example from Upstream HVAC Evaluation follows 7 Original Roadmap ApproachChallenges and Issues Field monitoring will be done for both participant and non- participant units in the residential and commercial sectors across a variety of climate zones and building types Consider participant non-participant, 3 HVAC types, 6 key climate zones and at least 5 building types means 180 strata for sampling. Therefore even minimal samples will create costs far exceeding the budget for even simple metering of unit power. Sampling detailed performance would further limit the sample by increasing cost per point.

8 DNV GL © 2013 February 12, 2014 Upstream HVAC Evaluation A phone survey and followup onsite effort to verify installations and characterize installed application may be able to achieve large samples Mini-split Evaluability assessment: Include data collection to first determine baseline and applications through surveys. Several metering challenges can be outlined through literature review, with metering protocols established through a pilot/case study. Conduct a metering pilot to determine whether AMI data (SmartMeters) can be leveraged to fill all the strata needed based on comparison to direct end use meters with remote communications. – Year 1: Phone and onsite surveys to determine install rate and applications of installed units; – Year 1: Separate project: Pilot remote metering and correlation to AMI Coordinate with WB interval data study conducted by IOUs, compare AMI-based HVAC estimates to meters installed on individual HVAC units – Year 2: Either more verifications or begin monitoring starting with highest savings climate zone (1) and building type (1) combination per IOU 8

9 DNV GL © 2013 February 12, 2014 Quality Installation Evaluation Challenge of metering and measuring a sufficient number of non-participants to compare both QI and To Code participants against Focus on participants in the two programs (QI and To Code) since the budget is $500k. The larger market assessment should conduct the non- participant assessments since the budget is $1.25M. Non-participants under 2008 Title 24 would include installs from 2009 to June – Year 1: Participant and Non participant sample design with project review followed by monitoring and testing, – Year 2: Small WO or add-on for direct observations if needed 9

10 DNV GL © 2013 February 12, 2014 Quality Maintenance Evaluation Ex-post observations followed by debrief to program and technician. Sub-sample may include case study to estimate achieved and remaining energy savings potential. Without pre-measurement, installation rate is primary parameter measured, some UES assumptions in workpapers can be modified with measurements after measures are installed, but does not inform measure baseline without pre- measurement. Work on pre-post coordination, but not on the annual reporting timeline. This means Pre in 2014 and Post in Otherwise the program measures may need to be all installed at the same time which is not part of program design, but is needed to streamline ex post M&V. – High Priority: Continue Lab work and site visits with interim reports on findings – Year 1: Reporting on ex-post sample followed by case studies of achieved and remaining energy savings potential. – Year 2: Reporting for pre-post monitoring with direct observation… results delayed to overcome coordination challenges 10

11 DNV GL © 2013 February 12, 2014 Deemed HVAC Evaluation A gap exists for measures that are not addressed in QI, QM, and upstream programs. Examples include HVAC controls, VFDs for HVAC, and boilers and furnaces. Scope will depend on the magnitude of the savings as well as the uncertainty in the DEER or workpaper estimates. Field data collection should focus on obtaining parameter level data to reduce savings uncertainty. Perhaps focus on gas measures not studied in and not mentioned in (e.g. residential furnaces) given all other efforts focusing on cooling. Deemed study can identify data that needs to be collected in other efforts especially if deemed measures exist at Upstream, QI, QM, and non-participant sites – Year 1: Uncertainty analysis and focused study. Perhaps on gas measures not studied in and not mentioned in (e.g. residential furnaces) – Year 2: Data collection to be defined by year 1 uncertainty/gap analysis 11

12 DNV GL © 2013 February 12, 2014 HVAC Laboratory Testing Lab testing is an ongoing activity spanning multiple program cycles. Lab testing is an integral part of the overall HVAC Program impact evaluation as it provides insights into the impact of installation techniques and service actions that are not possible in a field only study. – Any testing identified in the plans or during the cycle that was not completed will be addressed during the cycle. – Additional tests will be identified based on the needs of the DEER updates, non- DEER workpaper reviews and ex-post impact evaluation. – Tests will be conducted in qualified laboratories using AHRI, ASHRAE and/or ANSI standards. Two Phases: Conduct lab work not completed in and reserve funds to test based on new field findings – Year 1: WO to test 2 large and 2 small units already at Intertek – Year 2: Set aside contingency to plan and conduct additional lab tests based on new field findings 12

13 DNV GL © 2013 February 12, 2014 HVAC Market Assessment: Code Compliance Multiple research questions, such as – Develop a baseline for permitting and compliance for HVAC changeouts – Characterize conditions of existing systems and awareness of market actors – Determine barriers to permitting and compliance Site surveys for non-participants as they will serve as a baseline for both QI and To Code. QM participants should be excluded. Market Actor interviews should include: HERS Raters, Code Officials (part of permit data collection), CSLB, Contractors, Distributors, CEC Code setting staff. The IOU Market Assessment may be a good gateway survey of customers to identify non-participants and then offer a follow-up onsite – Year 1: Permit rate study, market actor interviews; Await IOU customer surveys before fielding non-participants site visits – Year 2: Compliance study, same onsite procedure as QI and To Code 13
