Buildings

Commercial buildings use a significant amount of energy, accounting for almost 20 percent of all energy consumed in the United States. Companies are taking steps to reduce energy use in buildings, including upgrading lighting systems, switching to more energy efficient office equipment and appliances, and using technology to better manage energy consumption.

The resources below include presentations, reports and news on energy efficiency improvements in commercial buildings, as well as links to other organizations and web sites active on this issue.

Companies including Air Products, Citi, Deere and Co., Exelon, and United Technologies presented on their strategies to reduce energy use in their internal operations and facilities.
This report models the cost of inaction on energy issues, and highlights measures that can reduce energy consumption in buildings, such as building energy codes, labeling and reporting mechanisms, and investment subsidies.
This report is an integrated assessment of various LEED standards, taking into consideration factors such as energy, water and indoor environmental impacts.
The Empire State Building’s high-profile $500 million retrofit is signaling the potential for expanding the global market for energy efficiency investment.
View a listing of various business-government and business-NGO partnerships designed to advance more energy efficiency strategies in building construction and maintenance.
This program level site includes instructions on how an organization can participate in Energy Star programs related to energy efficiency in facilities.
A new tool from the Rocky Mountain Institute helps calculate greenhouse gas emissions from buildings – from site development, construction and operations. This online calculator uses project information to generate a building performance report, and can be used to determine the impact of energy efficiency construction or retrofits.
Using LEED standards as a guideline, Marriott International is decreasing design time and construction expenses while developing a hotel prototype that also significantly reduces water and energy consumption.
Reporting from Sacramento - When octogenarian Arthur H. Rosenfeld vacates his utilitarian office at the California Energy Commission this week, one of his final tasks might seem of little consequence: He'll turn off the lights.
PORTLAND, Ore. — Urban gardening used to seem subversive. People planted tomatoes in public parks, strung their hops to rooftops to make homebrew and reclaimed empty lots as community farms, never mind the property owner.
GE has dedicated a $45 million Renewable Energy Global Headquarters in Schenectady, N.Y., which also has created more than 650 new jobs. The event also marked the installation of GE’s 13,500th wind turbine globally. GE is the largest supplier of wind turbines in North America.
Horizon at Playa Vista, a new 466,000-square foot urban office development in the Los Angeles area, plans to use renewable energy sources to power 70 percent of the building’s core and shell electricity needs, which will be minimized by the use of high-efficiency windows and reduced lighting density.
Although energy use can account for up to 70% of an MIT building’s operating cost, exactly where and why that consumption occurs is not obvious. And when a blip in a building’s internal workings can lead to even higher costs, it helps to know what’s going on, energy-wise, around the clock.
The U.S. Environmental Protection Agency’s Energy Star Leaders prevented the emissions of more than 220,000 metric tons of carbon dioxide and saved more than $48 million across their commercial building portfolios in 2009. The EPA says these savings have quadrupled since 2008 and is the single greatest year of savings since the program’s launch in 2004.
A panel of experts convened by the mayor and City Council issued more than 100 recommendations Monday on how to make New York City’s building codes more environmentally sound by imposing energy-saving requirements on construction and renovation work.
