Cost-effectiveness evaluations compare energy efficiency's benefits and costs to judge whether to expand, retain, revise, or eliminate efficiency programs or specific measures. This presentation discusses the basics of cost-effectiveness assessments for utility customer-funded efficiency portfolios as well as issues and options that should be considered when assessing cost-effectiveness, selecting which test(s) to use, and quantifying the components of tests (e.g., non-energy impacts, measure costs).

This presentation covers the current pilot project testing M&V2.0 as an evaluation tool facilitated by Connecticut Department of Energy and Environmental Protection (CT DEEP).  Speakers on this panel presented examples of how whole building modeling is currently being used for M&V now and its potential future applications. Speakers also discussed benchmarking, data access and other protocols, and how experience with efficiency programs teach us so we can build upon the current experience.

The Multi-State Residential Retrofit Project is a residential energy-efficiency pilot program, funded by a competitive U.S. State Energy Program (SEP) award through the U.S. Department of Energy. The Multi-State Project operates in four states: Alabama, Massachusetts, Virginia, and Washington. During the course of this three-year process evaluation, Cadmus worked closely with NASEO and the four states to collect information about the programs from many perspectives, including: State Energy Office staff, program implementers, homeowners, auditors/contractors, real estate professionals, appraisers, lenders, and utility staff. This report discusses: the project’s context; its goals; the evaluation approach and methods; cross-cutting evaluation results; and results specific to each of the four states.

Presentation on the SustainableWorks non-profit general contractor model for supporting energy upgrades in Washington state and lessons learned for implementing a whole house approach.

Pacific Power contracted with The Cadmus Group, Inc., to conduct impact and process evaluations of its Washington low-income weatherization program for the program period extending from March 2009 through February 2011. The impact evaluation assessed energy savings and cost-effectiveness associated with the program, and in doing so quantified select non-energy benefits. The process evaluation assessed program delivery and efficacy, potential bottlenecks, opportunities for improvements, and participants’ experiences and satisfaction with the program.

Evaluation reports from the Seattle Community Power Works program. The city of Seattle worked to encourage efficiency upgrades for single-family and multi-family residences, small businesses, hospitals, and large commercial and municipal buildings.

This mid-program evaluation includes extensive analysis of program sectors, including results of surveys of participants, and summarizes lessons learned to date.

As part of its "intentional learning" process, Charleston WISE collects information from homeowners that helps the program systematically test assumptions and implement continuous improvement.
