  • Green Building: An Introduction EPA Kansas City, KS Science & Technology Center: LEED Gold, Federal Energy Saver Showcase Facility Ken Sandler, US EPA Environmental Law and Policy Review Symposium William & Mary Law School January 30, 2009
  • Outline of today’s discussion
    • The environmental impact of buildings
    • Defining green building
    • The components of green
    • Green building in the marketplace
    • Redefining green building
  • The Environmental Impact of Buildings
    • Buildings in the U.S. are responsible for
      • 39 % of our energy use
      • 69 % of electricity consumption
      • 38 % of carbon dioxide emissions
      • 12 % of fresh water consumption
      • Urban runoff = a major threat to water quality
      • Over 2/3rds of non-industrial secondary materials
    • We spend 90% of our time indoors, where air is 2-5x more polluted than outdoors
      • Serious health and productivity impacts
  • Defining Green Building
    • Maximizing the efficiency with which buildings use resources:
      • Energy
      • Water
      • Materials
    • and minimizing their impacts on human health and the environment
    • through how we design, construct, operate maintain & reuse buildings and their sites
  • The Components of Green Building
    • Energy efficiency & renewables
    • Water efficiency & stormwater management
    • Green materials and products
    • Sustainable sites
    • Indoor environmental quality

        • Strategies, ordinances, etc. to replace sprawl with livable, walkable, attractive communities
      • Brownfields www.epa.gov/brownfields
        • Grants to clean up and reuse contaminated sites
  • Indoor Environmental Quality (IEQ) EPA Research Triangle Park, NC Main Building
  • Indoor Environmental Quality (IEQ)
    • Goal: Ensure that indoor spaces promote optimal levels of health and performance
    • EPA Programs:
      • Indoor Environments www.epa.gov/iaq
        • Tools for Schools: partnership program for schools to improve their IEQ
        • Radon: Building or mitigating homes to remove radon (#2 cause of lung cancer)
        • Asthma: educating health providers and patients to reduce indoor asthma triggers
        • Energy Star Indoor Air Package: specifications for new homes to improve IEQ
  • Putting It All Together EPA Potomac Yard, Arlington, VA: LEED Gold, ENERGY STAR
  • The Whole Building Perspective
    • Goal: Make the building work cleanly, efficiently and effectively as a whole system
    • U.S. EPA
