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.

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 updates ACEEE's 2013 assessment of multifamily energy efficiency programs in US metropolitan areas with the most multifamily households. Using housing, policy, and utility-sector data from 2014 and 2015, this report documents how these programs have changed in the context of dynamic housing markets and statewide policy environments. The report also offers an analysis of the number, spending, offerings, and targeted participants of current programs and their potential for further expansion.

This presentation describes how programs have leveraged data to increase program energy savings, with a spotlight on advanced and real-time monitoring and verification (M&V 2.0), contractor scorecards, and intelligent quality assurance (QA) and monitoring.

This report details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.

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.

NEEP has been tracking the residential lighting market for several years and has provided analysis in many reports. As the transformation of this complex market gains traction, we find the conversation and need for new information narrowing to one key topic: LEDs. While CFLs continue to play a role in residences and amongst Northeast and Mid-Atlantic program administrators, the LED has transitioned into the starring role of the residential lighting show.

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.

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.

Among the many benefits ascribed to energy efficiency is the fact that it can help create jobs. Although this is often used to motivate investments in efficiency programs, verifying job creation benefits is more complicated than it might seem at first. This paper identifies some of the issues that contribute to a lack of consistency in attempts to verify efficiency-related job creation. It then proposes an analytically rigorous and tractable framework for program evaluators to use in future assessments.

This resource provides best practices and highlights case studies for how utilities, policymakers, building managers, and community stakeholders can improve access to energy usage data while working towards the goal of improving efficiency in their communities.

This summary report provides scientific results, lessons learned, and recommendations for driving energy efficiency in existing buildings on an urban scale. It includes program marketing lesson learned, such as: personal outreach and call to action events are critical marketing opportunities.

Quick summaries of strategies various programs have used to improve the efficiency of delivering efficiency.

This presentation answers the questions of why and how to quantify the air quality impacts of energy efficiency policies and programs.

Presentation that provides insights from a utility executive on how energy efficiency programs can effectively partner with utilities.

This webcast reviews the SEE Action report that describes how utility planning processes that allow demand-side resources to compete with supply-side resources can promote cost-effective energy efficiency.

This report explores the best practices that utilities should undertake in the development and implementation of energy efficiency programs. The report calculates the impact that investing in energy efficiency will have on jobs, household income, and state and regional economies, along with the other public health benefits such as reducing pollution.
