This report is part of a series of "baseline" reports intended to inform the second installment of the Quadrennial Energy Review (QER 1.2). QER 1.2 provides a comprehensive review of the nation's electricity system and cover the current state and key trends related to the electricity system, including generation, transmission, distribution, grid operations and planning, and end use. The baseline reports provide an overview of elements of the electricity system. This report focuses on end uses, electricity consumption, electric energy efficiency, distributed energy resources (DERs) (such as demand response, distributed generation, and distributed storage), and evaluation, measurement, and verification (EM&V) methods for energy efficiency and DERs.

State and local governments across the U.S. are focused on how clean energy can help them meet a variety of energy, economic development, and environmental goals. An early step for most energy efficiency planning involves identifying and quantifying energy savings opportunities, followed by understanding how to access this efficiency potential.  This website includes national and state-level energy efficiency potential studies for the residential, commercial, and industrial sector.  It introduces presentations on how building energy codes, city-led efforts, energy savings performance contracting (ESPC), industrial, and ratepayer-funded efforts can support state energy planning. 

This guide helps real estate professionals understand how to provide home energy information to consumers and helps facilitate multiple listing services in delivering verified energy data.

This market snapshot of HVAC installation verification tools illustratively presents the categories and uses for the growing market of tools.         

This HVAC verifications tool selection guide includes a cross-walk of tool categories with target user audience, benefits and features. This matrix can assist contractors, programs, utilities and others in selecting the appropriate resources to support installation and performance measurement.

This paper gives municipal leaders tools to assess local energy resilience, a new term for the interconnection of community resilience and various aspects of energy supply and consumption. It looks at different aspects of this concept, like thermal building performance and transportation connectivity, and methods communities can use to assess them.

The adoption of intelligent efficiency applications is increasing across multiple sectors of the economy. This report analyzes over two dozen of these applications in the buildings, manufacturing, transportation, and government sectors. We describe the technologies involved, characterize their use, and quantify their deployment. We also look at several enabling and cross-cutting technologies and the use of intelligent efficiency in utility-sector energy efficiency programs.

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 guide is designed to help environmental agencies better understand the array of Lean methods and when to consider using each method. The guide focuses primarily on Lean production, which is an organizational improvement philosophy and set of methods that originated in manufacturing but has been expanded to government and service sectors.

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 population of HVAC and home performance buyers is largely made up of baby boomers. The goal of this guide is to explain why programs should consider the baby boomer audience and outline the best ways to market to this audience.

This presentation covers details of an in-store market test for Super-Efficient Dryer (SED) marketing collateral. Five different marketing message concepts were created based on previous consumer research. The concepts include: an image, a headline of the key benefit, and a brief product description to drive credibility.

This white paper covers a few of the business-to-business marketing goals including social media strategies critical for an energy auditing business in today's world, while providing insights into how to make the most of these efforts.

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 comprehensive national guide provides a step-by-step process to apply the Resource Value Framework and allow jurisdictions to develop their own primary cost-effectiveness test -- the Resource Value Test. It provides guidance using lessons learned in state and local jurisdictions over 20 years.

These policies provide protections for homeowners using PACE to invest in clean energy, energy efficiency, and water efficiency home upgrades. The standards address eligibility, repayment, disclosures, privacy concerns, contractor conduct, and operational requirements for PACE Programs.

This document covers preliminary findings from research on installation practices for the residential retrofit HVAC market.

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.

The report summarizes a survey of realtors about sustainability issues facing the real estate industry nationally and regionally.
