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 explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.

The multifamily sector can be hard to reach when it comes to energy efficiency programs. Besides being diverse and complex, the sector presents a unique set of challenges to efficiency investments. The result is that multifamily customers are often underserved by energy efficiency programs. Drawing on data requests and interviews with program administrators, this report summarizes the challenges to program participation and identifies best practices that programs can use to reach and retain large numbers of multifamily participants.

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.

This U.S. Environmental Protection Agency resource is intended to help state and local governments design finance programs for their jurisdiction. It describes financing program options, key components of these programs, and factors to consider as they make decisions about getting started or updating their programs.

This publication outlines capital leveraging models and examples from across the country in which public funds were used to influence energy loan program capital.

Outlines five public-private financing mechanism options for energy efficiency upgrades programs, including on-bill financing, PACE financing, and loan loss reserve funds.

This paper, which is based on detailed case studies of nine existing state and local programs, presents recommendations for energy upgrade programs to facilitate industry growth and support contractor business models.

This report summarizes existing research and discusses current practices, opportunities, and barriers to coordinating energy efficiency and demand response programs.

This guide helps states and localities develop voluntary or mandatory programs that go well beyond minimum code requirements for new buildings. It addresses energy efficiency materials and resource conservation, water efficiency, indoor environmental quality, and site development and land use.
