The catalog is a compilation of state and local energy efficiency potential studies to serve as a resource for energy planners and as a baseline for future analyses.

This paper is a baseline assessment of electric and natural gas energy efficiency programs that target low-income households in the largest metropolitan areas in the country. ACEEE surveyed over 70 electric and natural gas utilities on their 2015 low-income program spending, energy savings, customer participation, and best practices.

This report is a guide to all customer-facing financing products—products offered by a lender directly to a borrower—used to pay for energy efficiency. Intended for state and local governments that are deciding whether to start a new program, tune up and existing program, or create a Green Bank, it provides information on the full range of financing product options for target participants, the tradeoffs of various products, and potential advantages and disadvantages for different types of customers.

This Guide is designed to help state and local policymakers to take full advantage of new policy developments by providing them with a comprehensive set of tools to support launching or accelerating residential energy efficiency programs. The Guide focuses on four categories of policies that have proven particularly effective in providing a framework within which residential energy efficiency programs can thrive: incentives and financing, making the value of energy efficiency visible in the real estate market, data access and standardization, and supporting utility system procurement of energy efficiency.

Home Performance with ENERGY STAR’s new HPXML Implementation Guide helps energy efficiency program administrators and software developers overcome fragmented data exchange by integrating HPXML (home performance extensible markup language) into their operations and products. HPXML is a set of common definitions for the attributes of home systems based on Building Performance Institute data standards and the computing language that facilitates the quick and easy transfer of home-related data between different markets.

This case study presents information about the AlabamaWISE program. It includes background information, approaches the program took to enhance home energy efficiency, and results achieved by the program.

There are more than 17 million multifamily households nationwide, yet they remain a significant and mostly untapped opportunity for energy efficiency gains. Many cities and states that have embraced energy retrofitting as a job creator and boon to both the environment and economy have yet to address potential savings in multifamily properties, primarily because of obstacles not faced by single family and commercial properties. This paper discusses two barriers -- a lack of information and financing -- that stand in the way of multifamily energy retrofits.

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

Philadelphia EnergyWorks helped sustain future programs by sharing marketing insights and program data with a local utility partner.

This interim evaluation report examines the design, delivery, and market effects of each of the Southeast Energy Efficiency Alliance's (SEEA) thirteen sub-grantee programs and identifies opportunities to increase each program's success, and quantifies and verifies the energy savings achieved through the programs' funded home energy improvements and the cost-effectiveness of those savings.

This report summarizes ongoing and recent policy developments that support utility investments in energy efficiency, including program cost recovery, fixed cost recovery, and performance incentives for electric utilities on a state-by-state basis.

This peer exchange call summary focused on how programs are devising plans for creating a contractor revenue stream and potential fee structures.

Case study highlighting Philadelphia's use of QECBs to finance energy efficiency upgrades for City buildings.

Outlines Philadelphia's EnergyWorks program's use of low-interest loans to incentivize homeowners by tying the interest rate to the number of energy efficiency measures incorporated into the home.

This report identifies issues associated with developing a national evaluation, measurement, and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities.

This report presents the results of a scoping study to assess the need for national databases that can support best practices in energy efficiency program evaluation, measurement, and verification (EM&V).

This report helps policymakers understand how electric and natural gas utilities can achieve greater efficiency by establishing numeric energy savings targets and goals for energy efficiency programs.

This market assessment for the Alabama Energy Revolving Loan Fund identifies the customers and potential demand for an energy efficiency upgrade financing program.

This webcast presents Pennsylvania's Keystone HELP program as a case study for successful public/private partnerships for consumer energy efficiency financing.

This report provides an overview of evaluation, measurement, and verification approaches used to estimate the load impacts and effectiveness of energy efficiency programs.

This brief focuses on loan programs in 30 states that are currently providing low- to no-interest loans to finance energy efficiency improvements--from energy-efficient windows to replacement HVAC systems--in the residential, business, and public sectors.
