Weatherization Energy Auditor Single Family Measure Selection Guidelines
This document outlines the measure selection guidelines for energy auditors in the Weatherization Assistance Program. It covers criteria for selecting weatherization measures, Appendix A requirements, SIR calculations, and data needs such as energy consumption and total costs for replacements. The guidelines ensure that only approved measures are installed, materials meet standards, and SIR of at least 1 is achieved.

WEATHERIZATION ENERGY AUDITOR SINGLE FAMILY Measure Selection Guidelines WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 1 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Learning Objectives MEASURE SELECTION GUIDELINES By attending this session, participants will be able to: Describe selection criteria for weatherization measures. Identify Appendix A of the DOE WAP Rule 10 CFR, Part 440. Explain the concepts of present value and fuel escalation rate as they relate to SIR. Practice SIR calculations. 2 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Measure Selection Guidelines MEASURE SELECTION GUIDELINES Appendix A SIR 1 o Based on DOE-approved audit o Present value of money o Fuel escalation rate 3 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Appendix A MEASURE SELECTION GUIDELINES Can only install measures listed in Appendix A Materials must meet standards for conformance based on Appendix A Example: Replacement Water Heaters Standards for Conformance Electric (resistance) water heaters 10 CFR1 430 and UL3 174. UL 1995, Second Edition, 1995. Electrical components to be listed by UL. Heat pump water heaters Andmust have SIR 1. 4 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
SIR Data Needs MEASURE SELECTION GUIDELINES Energy consumption of existing item Energy consumption of replacement item Total cost of replacement: o Price and installation costs of new unit o Cost of removal and decommissioning of old unit Local utility rates Discount rate o Fuel escalation rate o Present value 5 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Fuel Escalation Rate MEASURE SELECTION GUIDELINES Annual escalation rate of fuel prices based on the annual energy price forecasts of the DOE Energy Information Administration. 6 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Discount Rate MEASURE SELECTION GUIDELINES The interest rate at which expected future cash flows can be discounted. In WAP, includes fuel escalation rate. Like interest rate paid on a loan, in reverse. Saving $100 15 years from now is worth less than saving $100 today. The discount rate accounts for the time value of money. 7 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
SIR Calculations MEASURE SELECTION GUIDELINES Alternately: Use DOE-approved audits with built in SIR Use spreadsheet PV function 8 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Using PV Function for SIR MEASURE SELECTION GUIDELINES SIR equation = - PV (% , n , Savings/Year) Cost Where: % = DOE provided discount rate. n = Lifetime of measure, in years. Savings/year is based on local utility data. Cost = Total cost of installation. 9 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Client Acceptance MEASURE SELECTION GUIDELINES Appendix A SIR 1 Client acceptance If the client does not want certain measures installed, then you have two choices: 1.Continue with weatherization, minus the unwanted measures. 2.Defer weatherization services. 10 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Summary MEASURE SELECTION GUIDELINES Measure Selection Guidelines: Measures must be listed and conform to Appendix A standards. Measures must have an SIR 1 based on local costs and savings, with savings discounted to the present value of money. You cannot force a client to accept measures. The auditor has the right to defer services. 11 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
