GREEN POINTS: The 70,000-square-foot (6503-m2) facility provides an environment for private business owners to share experiences and knowledge and participate in workshops and programs that are designed to inspire new thinking. Sustainable design is integral to the building; 50 percent of water used on-site comes from rain or greywater. Geothermal heat loops rely on the natural heat storage capacity of the earth for heating and cooling. Window glazing that lets in natural light and solar panels that heat the hot-water system help reduce the building’s energy consumption by 50 percent.

GREEN POINTS: Building 88 recently was LEED Gold certified for Commercial Interiors from the Washington, D.C.-based U.S. Green Building Council. About 750 offices are integrated into 217,000 square feet (20159 m2). A 2-story central atrium has a skylight, so natural light can filter into the building, and localized light and temperature controls allow occupants to customize individual spaces to personal comfort levels. Bicycle storage is located near building entrances, and access to public transportation encourages employees to commute. About 88 percent of construction waste was recycled, diverting 1,450 tons (1315 metric tons) of material from landfills. About 20 percent of materials used included recycled content, and 28 percent of materials were manufactured within a 500-mile (805-km) radius. Carbon-dioxide sensors monitor CO2 levels and increase airflow when necessary.

GREEN POINTS: Encompassing nearly 50,000 square feet (4645 m2), the community center replaces two existing buildings. Public amenities include a full-service gymnasium, dance studio, computer lab, multipurpose rooms and a weight-training room. Sustainable elements include a reflective roof, permanent planters on the rooftop that reduce storm-water runoff and limit the need for potable water, proximity to public transportation, secure bike racks, changing facilities, and the use of low-VOC materials and dormered skylights. The project is seeking LEED Silver certification for New Construction from the U.S. Green Building Council, Washington, D.C.

GREEN POINTS: The 11,500-square-foot (1068-m2) building employs a geothermal-heat-pump system, which saves 40 to 50 percent on energy. Sewage is treated with a wetlands septic system and rainwater is collected in rain barrels for on-site use; no sprinkler system is installed. The building is designed on an east-west axis to promote natural ventilation and maximize the structure's connection to the sun. A glulaminated timber roof, which is made from smaller pieces of wood combined into a larger beam, is employed. The building envelope is designed with high-insulation values and energy-efficient windows; local and regional materials were used throughout construction. Lighting is controlled by occupancy and photocell sensors. The native Iowa tallgrass prairie also was restored.

GREEN POINTS: As the nation’s first commercial green bank, New Resource Bank offers special loan programs to green developers and finances residential and commercial solar installations. It recently was selected as a preferred financial partner of Solar Santa Monica, a solar campaign operated by the city of Santa Monica, Calif. Certified LEED Gold for New Construction from the Washington, D.C.-based U.S. Green Building Council, the building’s desks are manufactured from certified sustainable forest products and rapidly renewable bamboo. Much of the office furniture was purchased used. Cabinets are made from 100 percent pre-consumer recycled wood fiber, and the fluorescent lighting is controlled by motion-sensor switches and daylight control.

GREEN POINTS: Sweetwater Sound is the fourth-largest musical instrument and pro-audio retailer in the world. It recently completed a 180,000-square-foot (16722-m2) facility that features a 250-seat auditorium and performance theater with four separate sound systems combined with three new recording studios. Sales offices are clad in bamboo, and other rapidly renewable materials were used throughout the facility. A reflective, white roof and insulated, heat-treated glass is used on the building to reduce solar heat gain and limit the cooling load placed on the building’s mechanical systems. Light sensors automatically adjust the amount of light as necessary. Roof insulation increases energy efficiency. The facility is vying for LEED Gold certification from the U.S. Green Building Council, Washington, D.C.

GREEN POINTS: As Montana’s only LEED Platinum-certified structure recognized by the Washington, D.C.-based U.S. Green Building Council, this 8,300-square-foot (771-m2) building houses several nonprofit environmental groups. The building, which had been an abandoned 1940s grocery store, was refurbished for less than the cost of new construction. Its Earth-toned colors save 80 percent on energy, and solar panels meet almost half of office electrical demands. About 92 percent of deconstruction waste was recycled or reused, and 25 percent of materials came from sources within 500 miles (805 km) of Billings. Other green features include rooftop clerestories, cooling with outside air, radiant-floor heating, exterior rigid insulation, composting toilets and waterwise plantings.

GREEN POINTS: Built on a brownfield site, the Nationals Park is the first Major League Baseball stadium to receive LEED Silver certification from the Washington-based U.S. Green Building Council. Efficient field lighting, a 6,300-square-foot (585-m2) green roof and recycling help make the ballpark green. Millions of gallons of water will be saved each year through waterconserving plumbing fixtures and air-cooled chillers. About 20 percent of the ballpark’s construction used recycled materials and 5,500 tons (4990 metric tons) of construction waste was diverted from landfills. Because the site is close to the Anacostia River, a water-filtration system separates water used for cleaning the ballpark from rainwater falling on the ballpark. Both sources are treated before being released to the sanitary and storm-water systems. Special care also is given to screening organic debris, like peanut shells, from the storm-water system. Signs around the park educate visitors about the stadium’s sustainable aspects.

GREEN POINTS: Measures to reduce environmental impacts, such as using recycled materials, increased daylighting, low-emitting materials, innovative design and reduced water and energy consumption, earned the Kennecott Mine Administration Building and the Bingham Canyon Mine Visitor Center LEED Silver certification and LEED Certification, respectively, from the U.S. Green Building Council, Washington, D.C. The buildings’ uniqueness lies in their portability. As the mine expands and changes, the buildings can be combined with other modules to create larger or smaller buildings through reassembly. The buildings sit at an elevation of more than 6,000 feet (1825 m). In the administration building, two-thirds of the doors, frames and hardware used was salvaged from the previous mine-office building. In the visitor center, 30 percent of building materials were salvaged and reused by picking the existing building off its foundation and transporting it to the new center.

GREEN POINTS: This 4-story, 65,000-square-foot (6039-m2) public-housing agency uses 49 percent less energy than code requires. As an independent, governmental organization, the building is aligned along the east-west axis to reduce heating and cooling demands. Low-E glass and sunshades moderate heat and light. Rainwater is channeled into a circular garden for filtering before it enters the city’s storm-water system. Inside the building, water use is controlled by sensor-operated faucets, and mechanical systems are controlled through variable-speed drives, pumps and fans with economizer capabilities and zoned controls. Each floor contains employee recycling stations. Many building materials were locally manufactured and contain recycled content. All interior offices have access to daylight.
