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 guide supports the development, maintenance, and use of accurate and reliable Technical Reference Manuals (TRMs). TRMs provide information to estimate the energy and demand savings of end-use energy efficiency measures associated with utility customer-funded efficiency programs. This guide describes existing TRMs in the United States and provides recommendations for TRM best practices. It also offers related background information on energy efficiency; evaluation, measurement, and verification; and TRM basics.

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.

This summary from a Better Buildings Residential Network peer exchange call focused on innovative financing approaches programs are using to support residential energy efficiency.

This webinar is the sixth (in a series of six) hosted by USDA Rural Utility Service (RUS) and focusing on the Energy Efficiency and Conservation Loan Program (EECLP). This webinar provides an overview of Solar Photovoltaic (PV) Opportunities and the Energy Efficiency and Conservation Loan Program. It features the New Hampshire Electric Co-op's Solar PV Program and SunShot Solar Outreach Partnership (SolarOPs). SolarOPs is a U.S. Department of Energy program designed to increase the use and integration of solar energy in communities across the US.

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 summary from a Better Buildings Residential Network peer exchange call focused on energy modeling in multifamily homes.

This report provides an overview of considerations for designing and implementing successful energy efficiency financing programs for existing buildings in the residential and commercial sectors. Information on key issues related to energy efficiency financing programs, guidance to existing resources that provide more in-depth financing program design and implementation information, and strategies for delivering broad customer access to attractive financing products that enhance customer capacity and willingness to invest in energy efficiency to address "first cost" barriers are included.

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.

This report provides an overview of the current state of on-bill programs and provides actionable insights on key program design considerations for on-bill lending programs.

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.

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

This study looks at evidence of capitalization of energy efficiency features in home prices using data from real estate multiple listing services (MLS) in three metropolitan areas: the Research Triangle region of North Carolina; Austin, Texas; and Portland, Oregon. These home listings include information on Energy Star certification and, in Portland and Austin, local green certifications. Our results suggest that Energy Star certification increases the sales prices of homes built between 1995 and 2006 but has no statistically significant effect on sales prices for newer homes.
