Research Report A1501 - January 27, 2015

This paper describes recent advances in energy-saving elevator technologies and recommends a path for accelerating the uptake of these new capabilities. New building codes are stimulating the adoption of modern systems that can save more than 40% of current annual energy use. ACEEE recommends...

Research Report U1501 - January 14, 2015

This report analyzes ten categories of utility-sector energy efficiency programs that have achieved high participation among targeted customer markets. Despite issues with the nature and availability of participation data, the study draws on published data sources and interviews with program...

White Paper - November 05, 2014

This paper shows a range of energy intensities for water and wastewater services and in residential hot and cold water. We draw from existing data to develop national estimates of energy savings associated with water savings, including energy used in water conveyance, water heating, and water...

White Paper - March 12, 2015

The Environmental Protection Agency’s proposed Clean Power Plan establishes state-specific targets for carbon dioxide emissions from existing power plants. This tool is intended to help states document and claim emissions reductions resulting from the adoption of building energy codes as a means...

Research Report - February 11, 2015

Gamification turns a real-world activity into a game to make people more likely to do it. Over the past five years, utilities and third-party providers have developed scores of games that motivate and encourage people to save energy. This report describes and analyzes 22 of these games in depth...

White Paper - January 23, 2015

In this paper we provide further support of our comment already submitted to the record, focusing on two aspects of the provision in order to determine whether building energy codes should be considered in setting the standards of performance. The first aspect we focus on is what it means for a...

Research Report - January 07, 2015

Businesses that implement energy efficiency improvements often enjoy other benefits besides utility bill savings. However previous efforts to measure multiple benefits have been sporadic and far from rigorous. Still, evidence suggests that including non-energy impacts can reduce the payback time...

Research Report - December 18, 2014

A zero net energy (ZNE) building is a home or commercial building that on average produces as much energy as it uses, achieved through energy efficiency and renewable technologies.  Building energy codes can help us transition to ZNE construction for new residential and commercial buildings by...

Research Report - December 11, 2014

This report surveys transportation-sector strategies that use information and communications technologies (ICT) and have the potential to save energy. These include car and bike sharing, real-time transit information, in-vehicle ICT applications, vehicle-to-vehicle (V2V) communications, and...

Regulatory Filing - November 16, 2014

These comments were submitted to the Environmental Protection Agency in response to the proposed Clean Power Plan which would regulate carbon dioxide emissions from existing power plants.

Research Report - November 13, 2014

The U.S. economy shows signs of weakening. Among the reasons for less vigorous economic activity is the inefficient use of resources—and especially the inefficient use of energy. New information and communication technologies (ICT) make possible dramatically reduced costs and higher levels of...
