This study provides an overview of practices for quantifying and reporting avoided energy-water costs from demand-side measures. It also summarizes the regulatory guidance for incorporating water savings into cost-effectiveness screening for energy efficiency programs.

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 examines the history of pay-for-performance (P4P) energy efficiency approaches. As the report describes, there is a diverse spectrum of pay-for-performance programs but, at the most basic level, these programs track and reward energy savings as they occur, usually by examining data from a building's energy meters -- as opposed to the more common approach of estimating savings in advance of installation and offering upfront rebates or incentives in a lump-sum payment. The report finds that P4P has some important opportunities for increasing energy savings, but also key limitations that will need to be better understood through piloting and experimentation.

This report examines how State Energy Offices and state-level partners are supporting growth and uptake of Commercial Property Assessed Clean Energy (C-PACE) financing around the country. The report offers examples, insights, and strategies for State Energy Offices, green banks, state financing agencies, and other public and private entities to catalyze, accelerate, organize, and expand C-PACE markets.

This report discusses indoor air quality issues, including: wildfire smoke, dampness, and mold, and the effect of energy efficiency upgrades on these health-related issues. The report describes current state policies and programs in these areas, highlighting approaches for consideration by other jurisdictions.

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.

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.

This summary from a Better Buildings Residential Network peer exchange call focused on challenges and strategies for working in cold climates.

The Guide to Action provides in-depth information about over a dozen policies and programs that states are using to meet their energy, environmental, and economic objectives with energy efficiency, renewable energy, and combined heat and power. Each policy description is based on states’ experiences in designing and implementing policies, as documented in existing literature and shared through peer-exchange opportunities provided to states by EPA’s State Climate and Energy Program.

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 how a residential energy efficiency program can work with, for or as utilities.

This webcast discusses the background for U.S. Department of Energy’s Smart Grid Investment Grant (SGIG) consumer behavior study effort; the various utilities who are participating and what they each plan to include their respective studies; the quantitative results and qualitative lessons learned thus far from these studies; and the types of research will be undertaken by LBNL over the next several years.

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.

The lack of documented value of retrofit measures is a barrier to many homeowners doing upgrades - as most appraisals do not include energy improvements in their comparables, and the homeÕs future sale can prevent the homeowner from earning a return on their investment via lower energy costs. Once the industry develops a process for valuing the energy improvements, it can unlock the significant potential for retrofit work through market pricing signals (energy efficient homes are worth more) and enhanced access to capital for those purchasing a more efficient home (energy efficient homes improve borrowersÕ cashflow because they cost less to operate).

Presentation that focuses on grantee program-utility partnership models from the programs perspective.

This peer exchange call summary focused on the strategies, challenges and key interaction points with the real estate sector.
