  1. U.S. Green Building Council’s LEED Certification Program Dana Armanino Pollution Prevention Seminar Donald Bren School of Environmental Science and Management November 23, 1999

  2. Plan of Attack • Green Building - What and Why? • U.S. Green Building Council • LEED™ Certification Background • A look at the process with the help of case studies: Aspen Skiing Company’s Sundeck Restaurant Bren Hall

  3. What is Green Building? • No set definition or rules • General themes • Use recycled & recyclable resources • Use water, energy, lumber, and other resources efficiently • Localize resource inputs • Eliminate toxins • Protect & restore nature • Improve Quality • Conserve resources

  4. Why Build Green? • Decreased energy and water consumption • Increased health and productivity of workers • Expedited government approval processes • Decreased waste disposal costs • Creation of a more durable and long lasting building • Increased sales value of the property • Oh yeah, it is good for the environment, too

  5. Economics of a Building Source: Natural Capitalism, 1999

  6. Why Build Green? • Decreased energy and water consumption • Increased health and productivity of workers • Expedited government approval processes • Decreased waste disposal costs • Creation of a more durable and long lasting building • Increased sales value of the property • Oh yeah, it is good for the environment, too

  7. The U.S. Green Building Council • A non-profit 275 member consensus coalition formed in 1993 • Mission: “to accelerate the adoption of green building practices, technologies, policies, and standards” • Committee-Based: provides a forum for members to resolve differences, build alliances, and forge cooperative solutions • Member-Driven: targets issues identified by the members as the highest priority

  8. The U.S. Green Building Council • Product manufactures • Herman Miller • Armstrong World Industries • Environmental groups • Natural Resources Defense Council • Rocky Mountain Institute • Building and design professionals • American Society of Interior Designers • American Institute of Architects • Universities and Research Institutes • Lawrence Berkeley Laboratory • Monterey Bay Aquarium Research Institute • Retailers and building owners • Gap • Target Stores • Financial industry leaders • Bank of America • Real estate firms • Hines • Monsanto Company • Federal agencies • DOE • DOD • EPA • Local and state governments

  9. LeadershipinEnergyandEnvironmentalDesign • Voluntary, consensus-based, market-driven rating building rating system • Evaluates environmental performance from a “whole building” perspective over a building’s life cycle • Intended to be a definitive standard for what constitutes a green building • Based on accepted energy and environmental principles • Attempts to strike a balance between known effective practices and emerging concepts • Still in pilot and revision phase
