In 2012, EPA hosted its third season of the ENERGY STAR National Building Competition to see which U.S building could cut its energy use the most. More than 3,000 buildings from all 50 states, two U.S. territories, and the District of Columbia battled the scale and each other. This easy-to-read 27-page report gives details about the competition and shows what steps many of the "biggest energy losers" took to cut their energy use.

In response to a 2007 Congressional request, EPA developed this 133-page report to assess current trends in energy use and energy costs of data centers and servers in the U.S., and to outline existing and emerging opportunities for improved energy efficiency. It provides particular information on the costs of data centers and servers to the federal government and opportunities for reducing those costs through improved efficiency.

This wrap-up report takes a look at EPA's first-ever National Building Competition. Learn how 14 contestants were able to collectively reduce energy consumption by more than 44 million kBtu a year, save more than $950,000, and reduce greenhouse gas emissions equal to the annual electricity use of nearly 600 homes. A University of North Carolina residence hall took home first place. Filled with photos, tips, and ideas, this easy-to-read report will get your creative juices flowing.

This 12-page paper describes the voluntary ENERGY STAR program policy approach selected to engage and motivate the automobile manufacturing industry to improve its energy performance, and the results of the industry’s efforts to advance energy management as measured by the updated EPI. Most notably, the paper shows that electricity use per vehicle in the best plants improved by 2 percent, while the fuel use per vehicle improved by a dramatic 12 percent.

This paper from Duke University focuses primarily on the development of an updated ENERGY STAR industrial Energy Performance Indicator (EPI) for the cement industry and the change in the energy performance of the industry observed when the benchmarking system was updated from the original benchmark in 1997 to the new benchmark in 2008.

This report from the Northwest Energy Efficiency Alliance (NEEA) documents commercial building retrofit, renovation, and upgrade projects that have demonstrated or predicted performance of 30% or better than the average for comparable buildings. These profiles explore successful approaches to deep savings and energy performance, owner motivation and areas of innovation in order to accelerate market adoption of energy efficient retrofits. This work is part one of a three-phase project to develop case studies that demonstrate deep energy savings.

This report from the U.S. Green Building Council explains how high performing buildings show proven cost-effectiveness, boost employee productivity, enhance tenant health, reduce liability for owners, and increase a building's property value. Certification programs like LEED and ENERGY STAR are creating common benchmarks, support tools and opportunities for the public which offer market differentiation and create higher value for buildings.

This report from Maastricht University discusses the effects of the sustainability of commercial properties on their operating and stock performance. Investors considering incorporating the environmental performance of a building into investment decisions may benefit from this report. Using a sample of U.S. Real Estate Investment Trusts (REITs), the report estimates that an REIT's sustainability is positively related to return on assets, return on equity, and the ration of funds from operations to total revenue.

This report from the University of Illinois at Chicago defines responsible property investing (RPI) as including facets such as investing in ENERGY STAR certified properties, transit-oriented development, and redevelopment areas. It shows that investors could have purchased a portfolio consisting solely of RPI office properties over the past 10 years and had performance that was better, at less risk, than a portfolio of properties without RPI features.
