These strategies are focused on reducing the use of materials that contain volatile organic compounds (VOCs), which impact air quality. The following materials can be procured in low-or no-VOC content version on green projects with low-emitting material goals: Adhesives, sealants, paints, coatings, carpet systems, composite wood, and agrifiber products. Usually it is difficult to choose all low-or no-VOC products, so we must also plan for an "off-gas" period after construction is completed but prior to occupation of the building. This time allows the materials to release their chemical emissions, and the HVAC systems then purify the air so it is clean and safe for when the building is occupied. Recycled Materials LEED and other sustainability construction programs encourage the use of recycled materials in projects because they require the creation of less energy and support the diversion of waste from landfi lls. As construction managers, we are able to support these goals by helping the architects and owners identify opportunities to incorporate recycled materials. We also suggest local, recycled materials we've used on projects in the past. WE ARE GOLDEN. The Swenson Civil Engineering Building on the campus of the University of Minnesota Duluth is LEED Gold-certified. Construction waste for the project was minimized through reuse and recycling; metals, cement, and wood sorting bins were used during construction to conserve resources. Within the facility, 30 percent of building materials have recycled material content, 23 percent of the total building materials have been manufactured within 500 miles of the project site (including steel, gypsum, insulation, wood, and wall panels), and 50 percent of the total wood used was harvested from FSC-certified forests. Efficient Design and Plans Architects and owners incorporate efficiency into the building design in a number of ways, including: Heating and cooling design, lighting design and fi xtures, and water efficiency design. These efforts result in a facility with a smaller environmental footprint and lower operating costs over time. A V I A B L E A LT E R N AT I V E Construction Waste: By the Numbers In 2003, the United States Environmental Protection Agency estimated roughly 164M tons of construction and demolition (C&D) waste from buildings were generated in the U.S. annually. Of this quantity, 9 percent was construction waste, 38 percent was renovation waste material, and 53 percent was demolition debris. C&D waste constitutes an estimated 25 percent to 40 percent of the national solid waste stream. Local jurisdictions may experience higher C&D debris burdens. For example, over half of Wisconsin's solid waste stream consists of C&D debris. Some Army installations' C&D waste constitutes 80 percent 60 of their solid waste stream. Only 25 to 35 percent of C&D materials from buildings were estimated to be recycled. While recycling C&D materials may not be the norm, there is case study evidence to verify that salvage, reuse, and recycling is a COLLEGE PLANNING & MANAGEMENT / APRIL 2013 viable alternatives to landfilling waste and debris materials, and can be accomplished within the practical, budget, and schedule constraints of a construction or demolition project. At some sites, demolition debris diversion of over 90 percent and construction waste diversion of over 75 percent are being achieved through salvage for reuse or resale, recycling, composting, and other diversion methods. These waste reduction levels are often being achieved at lower costs than if all materials are disposed in a landfill. CPM Source: The Whole Building Design Guide (www.wbdg.org).
