2 SoCalGas Multifamily Sector State Wide Number of Existing Buildings: 3,126,000 (23 percent of residential buildings) Annual Energy Use: 11% SoCalGas Multifamily constitutes for 22% of the SoCalGas Residential sector consumption The potential amount of savings available in this market by 2024 for Multifamily is 1.44 MMTherms SoCalGas Residential Market Summary of Active Meters by Segment, ,575, 1% 1,775,184, 32% Single Family MultiFamily 3,641,993, 67% 2

3 Multifamily Results to Date program cycle the SoCalGas multifamily offerings only reached 51% of its savings goal, leaving 1.9 MMtherms to still be saved Therms 7,000,000 6,000,000 5,000,000 4,000,000 3,000,000 2,000,000 1,000,000 SoCalGas Residential Portfolio Savings Achieved and Savings Goals by Segment, ,963,384 2,057,945 PLA Multifamily Whole Building New Construction Savings Achieved Savings Goal HVAC Mobile Home MF Programmatic Efforts EUCA Multifamily 15 projects 95,000 therms saved MFEER Therms saved declining per year on average by 46% since 2006 In addition, program participation in SoCalGas has seen a steady decline in participation in its multifamily programs. 3

4 An Innovative, Comprehensive Approach A targeted, comprehensive and performance-based approach designed to deliver 15+% post installation savings in existing multifamily buildings Multifamily Efficiency Program Offerings For Existing Buildings Custom Retrofits Long implementation process High Cost Customer Burden Whole Building Inflexible program targets Extreme high cost customer burden Comprehensive Central System Solution Customer Benefits Premium incentives tied to meter-based savings High impact of savings based on bundled measures Monitoring and feedback The goal is to influence the underserved market to do more upgrades achieve greater savings 4

5 High Impact High Opportunity Offering Target the upgrade of both central domestic hot water system and water usage improvements thus capturing a multi-measure approach and stranded energy savings Gas Savings Water Central Storage Water Heater or Boiler Central Water Heater Modulating Temperature Controller Circulating Demand Pump Controller Low Flow Shower Heads Data Access Hot Water Usage Monitoring and Metering Service Participants must agree to complete all five qualifying measures, and any qualifying upgrades must meet or exceed prevailing codes and standards 5

6 Pay-For-Performance Incentives Premium incentives tied to post-installation savings Two Installments: 1 2 Post Installation Incentive* Performance tied directly to achieved savings *Post installation incentives will be capped based on total project measure costs 6

7 Customer Eligibility SoCalGas is targeting property owners and managers (5 or more units) of existing buildings and have a year or more of historical billing data Building must have a SoCalGas account Building must be served by a central water heating system with a recirculating loop 12+ months of stable building operations, historical data Participating properties must be not have been built later than 2001 Measures installed within acceptable timeframe Not currently participating in any other efficiency incentive programs* *After post installation incentive and 12 months of post metering, customer could be eligible to seek additional incentives in other EE programs 7

8 How It Works Comprehensiv e Assessment Qualification, Application & Commitment Project Implementation, Verification Post Installation Payment Performance Payment Month 2-3 Month 4-7 Month 8-14 Month 24 Reservation Review Assessment Submit Application & Sign Agreement Verification of installation Receive premeasurement (post installation) incentive Receive performance incentive 8

9 Goals and Benefits Program Goal The goal is to influence the underserved market to do more upgrades achieve greater savings Customer Benefits Comprehensive deep energy savings in existing multifamily buildings Ex post validation over 12 months for all projects, with savings determined using normalized metered data Supports benchmarking 9

10 EM&V Plan - Option C in IPMVP Two Step process 1. Gross savings using Option C Whole Building Establish baseline performance using billing data* Need large savings to stand out from data noise Weather and occupancy data available (required) Non-routine adjustment to account for unexpected changes such as building size, common area, management and/or operations. 2. Net-to-Gross Adjustment Develop and administer participant survey * SoCalGas is in the midst of installing AMI at a rate of 1 million meters per year. Monthly billing data will be available for all customers, while AMI data will be available for some customers. 10

11 EM&V Plan Models PRE (Prior to reporting period) Models Monthly: Fit regression model for energy use during baseline period from independent variables (HDD, CDD, occupancy rate) for each customer. AMI: Fit a baseline model using hourly AMI data against the Temperature and Time-of-Week algorithm developed by the LBNL for each customer. Exam significance of independent variables and goodness of fit. POST (After reporting period) Fit similar model of energy use during reporting period. Normalize both models to a typical meteorological year. Non-routine adjustment. Calculate gross and net savings using existing condition as baseline and uncertainties. 11

12 Free-ridership EM&V Plan Other Factors Apply screening at project initiation using questionnaire used in custom projects. Collect net-to-gross information immediately after project installation using generally accepted NTG survey instruments. Persistence. Energy savings will be tracked, calculated, and measured at fixed intervals. Population screening. Optional work to compare energy models of participating against non-participating buildings using number of units, locations, and/or equipment to assess which MF buildings would most benefit from Option C for future program expansion. 12
