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 report provides a comprehensive review and analysis of home energy upgrade programs with proven track records, focusing on those with robustly verified savings and constituting good examples for replication. This meta-analysis describes program models and implementation strategies for direct install upgrades; heating, HVAC replacement and early retirement; and comprehensive, whole-home upgrades.

This summary from a Better Buildings Residential Network peer exchange call focused on how recent policy changes have impacted residential energy efficiency program implementation. Speakers include Efficiency Maine, Michigan Environmental Council, and Groundwork Center for Resilient Communities.

This report identifies opportunities for Connecticut's Home Energy Solutions program (HES) to increase savings related to air sealing, duct sealing, and insulation.

This report presents the results from a comprehensive impact and process evaluation of Efficiency Maine's Low-Income Multifamily Weatherization Program.

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

Residential air-source heat pumps (ASHP) are a heating and air-conditioning technology that use electricity to provide a combination of space heating and cooling to homes. A new generation of ASHPs has come to market over the past five years. This report evaluates the key market barriers as well as potential opportunities to leverage. Based on an assessment of the regional ASHP market, it is clear that while ASHPs have established a viable and growing market, there remains a significant opportunity to further accelerate adoption of the technology and in the process achieve energy and cost savings to the Northeast and Mid-Atlantic region.

The Regional Roundup of Energy Efficiency Policy is intended to give policymakers, regulators, efficiency proponents, program administrators and other stakeholders a comparative view of the progress of energy efficiency policies and programs across the Northeast/Mid-Atlantic region. Along with state-level highlights, the report examines regional trends and shared challenges in harnessing the potential of energy efficiency to meet today’s pressing energy and environmental challenges.

This report represents NEEP’s annual assessment of the major policy developments of 2014, as well as its look into the immediate future, where NEEP gauge states’ progress toward capturing cost-effective energy efficiency as a first-order resource. While looking at the region as a whole, NEEP also provides summary and analysis of some of the biggest building energy efficiency successes and setbacks from Maine to Maryland — including significant energy efficiency legislation and regulations and changes in funding levels for energy efficiency programs.

This Multifamily Technical Reference Manuals (TRMs) provide documentation for the Trust's calculation of energy and demand savings from energy efficiency measures.

Energy efficiency collaboratives vary greatly and are typically designed for a specific jurisdiction, making them hard to compare side by side. This guide seeks to highlight a few common elements and draw conclusions on the overall effectiveness of specific characteristics of collaboratives. This guide defines and examines four different types of collaboratives in terms of their origin, scope, decision-making method, membership, duration, available resources, and how they interact with and influence their respective commissions.

A number of states are beginning to recognize Demand Reduction Induced Price Effects (DRIPE) as a real, quantifiable benefit of energy efficiency and demand response programs. DRIPE is a measurement of the value of demand reductions in terms of the decrease in wholesale energy prices, resulting in lower total expenditures on electricity or natural gas across a given grid. This paper reviews the existing knowledge and experience from select U.S. states regarding DRIPE (including New York and Ohio), and the potential for expanded application of the concept of DRIPE by regulators.

This summary from a Better Buildings Residential Network peer exchange call focused on choosing and developing program evaluation.

This report presents the results of an independent evaluation of Efficiency Maine Trust's Residential Direct Install Program for Fiscal Year 2013.

This summary from a Better Buildings Residential Network peer exchange call focused on gathering and communicating loan performance data.

This webcast discussed how market research can help spur demand for home energy efficiency programs.

REED serves as a dashboard for the consistent reporting of electric and natural gas energy efficiency program energy and demand savings and associated costs, avoided emissions and job impacts across the Northeast and Mid-Atlantic region. REED is a project of NEEP's Regional Evaluation, Measurement and Verification Forum (EM&V Forum) and is based on the EM&V Forum's Common Statewide Energy Efficiency Reporting Guidelines.

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 identifies and discusses factors that should be considered in evaluating model choices for administering and implementing ratepayer funded energy efficiency programs.

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

The purpose of this study is to furnish comprehensive information on ratepayer-funded low-income energy programs. This study includes information on and analysis of the energy needs of low-income households, the legal and regulatory framework supporting ratepayer-funded programs, program design options, and the findings from evaluations of program effectiveness.
