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 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 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.

The Regional Evaluation, Measurement and Verification Forum (EM&V Forum) works to support use and transparency of current best practices in evaluation, measurement, verification, and reporting of energy and demand savings, costs, avoided emissions and other impacts of energy efficiency, while also advancing the development of strategies and tools to meet evolving policy needs for efficiency.

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 looks into residential lighting savings assumptions found in Technical Reference Manuals (TRMs) throughout the Northeast and Mid-Atlantic regions to understand what values were being used for key metrics such as hours of use, delta watt, and measure life.  It provides the opportunity to view completed Standardized Methods Forms to compare evaluation methodology and results.

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.

The benefits of energy efficiency extend beyond energy savings. Homes, commercial buildings, and industrial facilities gain comfort, health, and safety benefits from energy efficiency programs. Additional benefits for businesses include savings on maintenance, materials, and the costs of regulatory compliance. On the supply side, electric utilities enjoy reduced system costs. Focusing on the residential, business, and utility sectors, this report examines each of these multiple benefits, their role in program marketing, and current best practices for including them in cost-effectiveness testing.

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 paper describes existing barriers to integrating energy efficiency data into real estate markets, and illustrates recent efforts to address them. National cross-industry collaborations have resulted in standard data collection and transfer tools that allow home performance data to be shared across industries. Real estate markets in some regions have begun including these data into multiple listing services (MLS), making them visible during real estate transactions.

The document provides best practices and guidance for conducting the energy analysis required for multifamily (MF) building energy improvement projects funded by the various programs of the Maryland Department of Housing and Community Development. The intended audience includes energy auditors, building owners and operators, contractors, designers, architects, engineers, and energy efficiency consultants and program staff.

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

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.

STEP was developed with a mission to "create a model community energy transformation program that serves as a roadmap for other small towns across the U.S." This final technical report summarizes the program's comprehensive energy evaluations for homes.
