This study provides an overview of practices for quantifying and reporting avoided energy-water costs from demand-side measures. It also summarizes the regulatory guidance for incorporating water savings into cost-effectiveness screening for energy efficiency programs.

This guide is designed to serve as a "how-to" reference for island communities (or small, similarly sized, more isolated communities) that want to develop and implement a residential energy-efficiency and conservation program. The purpose of this guide is to help communities chart a course for successful program development based on the lessons learned during implementation and operation of RePower Bainbridge, an energy-efficiency program on Bainbridge Island, Washington.

The lack of documented value of retrofit measures is a barrier to many homeowners doing upgrades - as most appraisals do not include energy improvements in their comparables, and the homeÕs future sale can prevent the homeowner from earning a return on their investment via lower energy costs. Once the industry develops a process for valuing the energy improvements, it can unlock the significant potential for retrofit work through market pricing signals (energy efficient homes are worth more) and enhanced access to capital for those purchasing a more efficient home (energy efficient homes improve borrowersÕ cashflow because they cost less to operate).

RePower helped consumers access aggregated information about financing and rebates by compiling a customer-friendly guide to all utility and non-utility incentives in its service area.

This paper, which is based on detailed case studies of nine existing state and local programs, presents recommendations for energy upgrade programs to facilitate industry growth and support contractor business models.
