Low-income tenants bear a particularly large burden for energy costs. Because their costs nearly equal those of higher income renters, energy accounts for larger shares of their incomes and overall housing costs. In 2011, more than one-fourth of all renter households had incomes below $15,000. These lowest-income renters devoted $91 per month to tenant paid utilities, while renters with incomes above $75,000 paid $135.

The U.S. Department of Energy's Smart Grid Investment Grant (SGIG) program worked with a subset of its projects undertaking Consumer Behavior Studies (CBS) to examine the response of mass market consumers (i.e., residential and small commercial customers) to time-based electricity rate programs, in conjunction with the deployment of advanced metering infrastructure (AMI) and associated technologies. The effort presents an opportunity to advance the electric industry's understanding of consumer behavior. This preliminary report summarizes experiences of the different phases of the enrollment process (qualification, solicitation, recruitment, and selection) across nine of the ten SGIG utilities, who collectively undertook 11 consumer behavior studies. It also provides experimental and descriptive results and lessons learned.

This white paper provides energy efficiency program sponsors and other stakeholders in the home performance industry with methods to document efficiency improvements and incorporate them into the real estate value chain. Making information about energy efficiency improvements visible to home buyers and others involved in a home sale transaction will play a crucial role in ensuring that improvements are fairly valued at the time an existing home is sold.

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).

Many states have adopted policies intended to overcome the barriers that limit the more efficient use of electricity. Yet because such efforts have not addressed the lack of consumer information and motivation to improve efficiency, many opportunities for energy efficiency remain untapped. To help address that problem, states, utilities, and other energy efficiency service providers have begun to develop new approaches to informing and motivating customers based on behavioral economics and psychology research. This report describes three broad strategies that states can use to engage consumers' participation in energy efficiency programs: provide direct consumer information and feedback on energy use, influence social norms; and match messages and messengers to target audiences. Recommendations for actions that governors can take within the context of each of those three strategies are provided.

This document summarizes discussions and recommendations from a forum for practitioners and policymakers aiming to strengthen residential energy efficiency program design and delivery for middle income households.

This paper explores ways in which program administrators are using social norms to spur behavior change and, as a result, curb energy use. In recent years, home energy reports (HER) programs have applied the concept of social norms to the energy efficiency context. These feedback programs inform customers of how their energy consumption compares to their neighbors' and provide other information about their usage, with the goal of enticing customers to change their energy use behavior to improve their relative neighborhood ranking.

This report describes how customer usage data can help promote the adoption of retro-commissioning polices for public and private commercial buildings.

Improving energy efficiency significantly lowers energy bills, creates jobs, and reduces pollution – benefits which all utility customers enjoy. The benefits of efficiency may be greatest in California’s low income communities, however, where poorly weatherized homes, high unemployment rates, and proximity to fossil-fuel fired power plants are too often the norm.

This whitepaper showcases how local governments and organizations promote energy efficiency through policies and program partnerships. Presents eight case studies from communities across the country, including two Better Buildings Neighborhood Program partners (Clean Energy Works Oregon (now Enhabit) and Energy Impact Illinois).

This is the first study to provide statistical evidence that, holding other factors constant, a green label on a single-family home in California provides a market premium compared to a comparable home without the label. The research also indicates that the price premium is influenced by local climate and environmental ideology. To reach these conclusions, researchers conducted an economic analysis of 1.6 million homes sold in California between 2007 and 2012, controlling for other variables known to influence home prices in order to isolate the added value of green home labels.
