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 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.

This report explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.

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 U.S. Department of Energy's (DOE) Building America research team, Advanced Residential Integrated Energy Solutions Collaborative (ARIES), worked with four public housing authorities (PHAs) to develop packages of energy-efficiency retrofit measures that PHAs can cost-effectively implement with their own staffs during the normal course of housing operations when units are refurbished between occupancies. More than 1 million public housing units supported by the U.S. Department of Housing and Urban Development (HUD) provide rental housing for eligible low-income families across the country, ranging from single-family houses to multifamily, high-rise apartments.

Energy efficiency is good for you--and for the air you breathe, the water you drink, and the community in which you live. This fact sheet shows how saving energy reduces air and water pollution and conserves natural resources, which in turn creates a healthier living environment for people everywhere. It includes the stories of a family in Pennsylvania and a hospital in Florida.

This guide for states highlights energy efficiency as a least-cost strategy to meet air pollution reduction and other policy objectives, including energy affordability and reliability. It presents established policy and program “pathways” to advance demand-side energy efficiency.

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 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.

This summary from a Better Buildings Residential Network peer exchange call focused on the advantages, challenges, and effective creation and management of statewide energy efficiency alliances.

This guide identifies 12 best practices for policymakers, regulators, and program administrators to help building owners invest to increase the energy efficiency of multifamily affordable housing.

This summary from a Better Buildings Residential Network peer exchange call focused on what residential energy efficient programs and strategies worked well in rural populations.

This summary from a Better Buildings Residential Network peer exchange call focused on how a residential energy efficiency program can work with, for or as utilities.

This report analyzes and develops estimates of non-energy impacts that could be included in cost effectiveness analyses for the EmPOWER Maryland energy efficiency programs. Four non-energy benefits are included in this analysis: air emissions, comfort, commercial operations and maintenance (O&M), and utility bill arrearages. In all four cases, a recommended value and methods for including them in future EMPOWER costs effectiveness analyses are provided.

This annual report summarizes the program's accomplishments in 2012, including the number of home upgrades, the cumulative amount of private investment leveraged for energy efficiency improvements, cumulative annual cost savings for building owners, and jobs created. It also includes testimonials from LEAP customers.

This peer exchange call summary focused on combining energy efficiency and health services.

The Small Town Energy Program (STEP) toolkit gives a complete overview of STEP from planning to implementation. It also includes access to a wide variety of materials developed by the program, including: local asset materials, partner materials, personnel materials, program administrative materials, outreach materials, and surveys. STEP has posted these toolkit documents with the hope that it will assist other small towns and communities in building and running more energy efficiency programs.
