Hosted by the Pacific Region communities of the U.S. Green Building Council, GreenerBuilder is a one-day conference and expo for green building professionals. The annual event unites all of the key players in greening the Pacific Region’s built environment—including architects, engineers and contractors—to discuss industry trends, new research and emerging technologies. GreenerBuilder is where you can get the strategies and tools to help create a more sustainable future in the region.

GreenerBuilder, hosted by the U.S. Green Building Council (USGBC), is a one-day conference and expo convening hundreds of general contractors, subcontractors, architects, engineers, design professionals, advocates and policy makers to discuss key green building trends, new research and emerging technologies in the building industry. GreenerBuilder unites all of the key players to discuss how the built environment can help California and the entire Pacific region meet ambitious climate change mitigation and energy conservation goals. Speakers include experts in green construction, architects, project managers, engineers, code experts and representatives from USGBC. Topics of discussion will include the latest trends in green building such as CALGreen building code updates, net zero energy, affordable housing, climate change, resiliency and public health. The conference is designed for those involved in construction, engineering, architecture, city planning and LEED project management. Register Today at greenerbuilder.usgbc.org
Chicago's natural history museum, the Field Museum, announced Monday it has earned a Gold rating from the U.S. Green Building Council under the LEED for Existing Buildings Operations and Maintenance (EB O+M) program, becoming just the second museum in the nation to do so. (The Madison Children's Museum is the other.) Two of the museum's halls already achieved LEED certification separately, including its Conservation Hall, which is LEED Gold. But Monday's announcement marks a building-wide rating seldom seen for such building types—the hulking museum, made of limestone and Georgian marble, comprises nearly half a million square feet. Its 3D Theater is also certified under LEED for Interior Design & Construction. Greening a museum that dates back to the 1893 World’s Columbian Exposition was no simple task. (The current building opened in 1921, originally planned by Daniel Burnham and designed by his associate William Peirce Anderson.) In many places its neoclassical stone walls don't have an air gap with the interior brick and plaster, making it difficult to regulate the building's temperature. And, as was made clear when the museum applied for LEED certification, it doesn't function on a typical building's schedule. “A normal building might shut down at 5 [o'clock], but not for us,” said Ernst Pierre-Toussaint, the museum's director of facilities, planning and operations. More than 99 percent of the museum's collection is in storage, which has to be climate controlled and monitored constantly. Pierre-Toussaint said improving energy efficiency has been a goal for at least 15 years. Working with the Delta Institute—an environmental consultant that worked with the Field Museum on the project—Field Museum staff replaced about 30 percent of the building's 6,700 incandescent bulbs with LEDs, and installed 100 kilowatts of rooftop photovoltaic panels. Pierre-Toussaint said they hope to install up to 220 kW more—enough to offset 10 to 15 percent of the building's peak electricity demand —by 2025. The museum accounts for all of its natural gas consumption by purchasing renewable energy credits and carbon offsets. Much of the certification work came down to mechanical system logistics. The museum has 11 separate electric meters, and 13 for water use. Since some collections and accessible areas need to be heated—even during summer—while others are cooled, the museum installed demand-control ventilation to regulate air in sensitive exhibits individually. “We made huge strides over the past two years and are proud to share the results with our visitors,” said Richard Lariviere, the museum's president, in a press release. “One of the big challenges is planning long-term,” said the Delta Institute's Kevin Dick. “You can certainly make quick fixes. But you know an institution like this isn't going anywhere. So in 40 years what will this look like?”
