Statewide Measure Cost Update: Overview & Discussion

This document provides an overview of statewide measure cost studies for energy efficiency measures, last updated in 2001, with the purpose of establishing common cost information. It discusses residential and commercial retrofit measures, potential issues, and next steps for creating a comprehensive database.

  1. Statewide Measure Cost Update Overview & Discussion

  2. Background & Purpose • Background • Measure cost studies provide the average incremental and full costs for new and retrofit energy efficiency measures (commercial and residential). • Typically performed in concert with DEER energy savings estimates. • Last update conducted in 2001. • Purpose • Create a common set of cost information and assumptions to be used as a starting point for all parties when planning and evaluating energy efficiency efforts. • Consistency with DEER measure descriptions. CALMAC Discussion

  3. Measure List • Initial measure lists will follow the DEER Update Study measure lists • Residential retrofit - weather sensitive and non-weather sensitive. • Non-residential retrofit - weather sensitive and non-weather sensitive. • Initial attention should be given to measures likely to represent the bulk of savings from 2006/7 program efforts • Consultant will review 2004/5 measure activity for IOU and non-IOU programs. • Consultant will suggest other measures for initial attention based upon impact of new standards upon likely program offerings. • CFLs (screw-in and modular), programmable thermostats, package and split system air conditioners, T-8 and T-5 lighting systems, clothes washers, dishwashers, pool pumps, and dual pane windows will be among the first measures examined. CALMAC Discussion

  4. Issues For Discussion • Should focus/scope be broadened beyond residential and commercial retrofit measures? • Industrial? • Commercial new construction? • Residential new construction? • Should installation costs be estimated for each measure or for a subset of measures? • Direct install program support. • More accurate cost comparison for individual measures with differing installation costs (e.g., condensing furnaces and water heaters). • Necessity of close linkage to DEER update efforts. • Advisory group makeup/requirements. CALMAC Discussion

  5. Issues For Discussion (continued) • Necessity of direct integration of measure cost information into DEER website. • Might require website redesign. • Updating issues (frequency & timing). • How should information from other EM&V studies be integrated? • Existing studies? • Studies in process? • Future studies? • Should/can existing studies work scopes be modified to collect measure cost data for direct inclusion into the DEER/Measure cost database? CALMAC Discussion

  6. Next Steps • Select advisory group members • Shahana Samiullah - SCE • Andrew Sickles - Sempra • Amalia Klinger - PG&E (Project Manager) • _____________ - CEC • _____________ - Energy Division • _____________ - ? • Prepare draft scope of work for advisory group review (week of 8/23) • Prepare proposal based upon advisory group comments (week of 9/6) • Select winning bidder (mid-October) CALMAC Discussion
