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.

This report consists of a literature review and in-depth interviews with subject matter experts in the Home Performance with ENERGY STAR (HPwES) program area. The goal was to compare Delaware Sustainable Energy Utility (DESEU) HPwES Programs with peer-programs across the United States. The report also identifies key metrics and emerging trends regarding program design.

This Technical Reference Manual (TRM) defines the consensus calculations of the electric and natural gas energy savings and the electric demand reductions, achieved from installing energy efficiency and renewable energy measures that are supported by Focus on Energy programs.

This summary from a Better Buildings Residential Network peer exchange call focused on obtaining and using energy efficiency data through tools like the Green Button, smart connected thermostat pilots, and operational ratings of homes to evaluate and/or enhance programs.

This summary from a Better Buildings Residential Network peer exchange call focused on standardization of effective practices across a program territory.

This summary from a Better Buildings Residential Network peer exchange call focused on the advantages and challenges of data tracking systems.

This report builds and expands off of previous research by collecting and evaluating data from 800 Illinois Home Performance (IHP) retrofits. This study investigates homeowner measure package choices in the Illinois Home Performance with ENERGY STAR® (IHP) program compared to cost-optimal choices determined through Building Energy Optimization (BEopt™) modeling software.

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.

The purpose of this report, prepared by sustainability consulting firm iSpring, is to provide the results of the EnergyWorks program to the contractors and auditors who participated, along with information on lessons learned over the course of the program that might prove helpful in their future work.

This report presents the impact evaluation conducted of the 13 programs in the Southeast Consortium Better Buildings Neighborhood Program (BBNP).

This report presents the phase 1 process evaluation conducted of the 13 programs in the Southeast Consortium Better Buildings Neighborhood Program (BBNP).

This report presents the phase 2 process evaluation conducted of the 13 programs in the Southeast Consortium Better Buildings Neighborhood Program (BBNP).

This report presents impact evaluation results for the Energy Savers program for large multi-family buildings. The Energy Savers program is run by CNT Energy and Community Investment Corporation. Initiated in January 2008 and now in its fifth year of existence, the Energy Savers program involves a variety of services to promote energy efficiency improvements for multi-family residential buildings of 5-50 units in the affordable housing market segment.

This peer exchange call summary focused on the challenges, advantages and disadvantages of using a home scoring system.

This peer exchange call summary focused on how to calculate and communicate program activities and results.

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.

This presentation provides the results of a 1,600-person survey of mid- to high-income households conducted by Energy Impact Illinois (EI2) to gauge attitudes toward home improvements and energy efficiency upgrades.

This peer exchange call summary focused on the different types of evaluation methods for residential and commercial programs.
