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.

What are the cost benefits to building green? This report from Springer Science + Business Media answers the question by exploring the relationship between green building design and leasing, as well as sales markets for commercial real estate. Energy efficient design can cost more, but it results in higher occupancy, rents, and selling prices for your ENERGY STAR certified projects.

This report from the Green Building Finance Consortium demonstrates that investing in energy efficiency enhances value in your real estate portfolios. This report takes a look at the growing demand for more efficient buildings, sales prices, lease rates and occupancy rates. It also provides real estate investors with academic and industry research, key steps, and best practices for integrating energy efficiency across your portfolios.

This report from the Institute for Market Transformation examines how mandatory rating and disclosure policies can help achieve real progress in reducing energy use and greenhouse gas emissions in U.S. commercial buildings. Using best practices in current policies, this paper lays out a policy framework for maximizing the market transformation potential of rating commercial buildings.

This paper from Maastricht University compares certified green buildings with nearby buildings and determines that buildings with green ratings command substantially higher rents and selling prices than otherwise comparable buildings. According to researchers, ENERGY STAR certified buildings command a rental premium of about 3%, have higher occupancy, and bring in a 16% premium on selling prices.
