New Green Building Standard Available ATLANTA—The first U.S. code-intended commercial green building standard will be available this month from ASHRAE, and a new version of Standard 90.1 is expected later this year. ASHRAE/USGBC/IES Standard 189.1-2009, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, will give state and local govStandard for ernments an enforceable tool to the Design of High-Performance conserve resources and increase Green Buildings Except Low-Rise energy efficiency. It was developed Residential Buildings by ASHRAE, U.S. Green Building Council (USGBC) and Illuminating Engineering Society (IES). The new standard covers key topic areas typically included in green building rating systems: site sustainability, water use efficiency, energy efficiency, indoor environmental quality, and the building’s impact on the atmosphere, materials and resources. It was written by experts representing all facets of the building industry. There were four public reviews, meaning anyone could comment on its proposed requirements. Some 2,500 comments were received during the reviews.

James Haughey, chief economist at Reed Construction Data, told ASHRAE Journal last month that nonresidential construction spending is predicted to fall another 11% in 2010 before it begins to rebound later in the year. The largest drag comes from the developer-financed commercial sector. “Rental rates are still falling and vacancies are increasing. It’ll be late this year before the situation is back to equilibrium and bankers entertain loan requests,” said Haughey. Spending for public sector construction has been down to a lesser extent. This sector, said Haughey, should benefit from stimulus funding, which is largely unspent. “So far the money has gone mostly to paving highways and bridge repairs,” he said. “There is a lot of money for public buildings, much of which is still in the planning stages. Architects and engineers should start seeing some of this money in 2010.” higher insulation levels, better glass, lower infiltration, reduced lighting loads and daylighting requirements. It also includes changes to system and component efficiencies, integrated controls and modeling. • Submeter tenant spaces over 10,000 ft2 (929 m2) by 2025; and • Conduct energy audits every 10 years beginning in 2013 and implement energy-efficient maintenance practices. “This legislative package is by far the most comprehensive package toward improving existing buildings’ energy efficiency in the U.S., and I believe it rivals leading major European city activities in the breadth of coverage,” said Adam Hinge, managing director of Sustainable Energy Partnerships. “While some of the press coverage has focused on dropping the mandatory retrofit piece of the initial audits and retrofits bill, the package that did pass sets up an opportunity to revisit some sort of mandatory performance improvement provisions a couple of years down the line,” he said. ashrae.org January 2010 IMPORTANT NOTICES ABOUT THIS STANDARD To ensure that you have all of the approved addenda, errata, and interpretations for this standard, visit www.ashrae.org/standards to download them free of charge.

ISSN 1041-2336 9 781104 12336 9 Product Code: 86602 12/09 THE NEW version of ANSI/ASHRAE/IES Standard 90.1 was developed with the goal of raising the overall minimum energy efficiency by 25% to 30% for all new and renovated buildings, except low-rise residential buildings. This is important because every state is required by federal law to meet or exceed the 2004 version of Standard 90.1 in their building codes. It is anticipated that the U.S. Department of Energy (DOE) will replace the 2004 version with the 2010 version of 90.1 at some point. The increase in stringency is achieved primarily through NYC Code ‘Most Comprehensive’ in U.S. NEW YORK—New York City has adopted what is described as the most comprehensive effort by any U.S. city to reduce emissions from large buildings. The legislation, passed in December, is expected to reduce the city’s greenhouse gas emissions by 4.75%. It creates the New York City Energy Code, which takes effect July 1, 2010, and requires new equipment installed during a renovation to meet the code. The laws also require building owners to: • Benchmark their buildings’ energy and water use annually beginning in 2011; • Upgrade lighting by 2025; 6 ASHRAE Journal
