Brian Dunbar on "Green Buildings That Teach"

  1. 1. Green Buildings That Teach Brian Dunbar, Exec. Director Institute for the Built Environment Colorado State University
  2. 2. The biggest issue in green building infusion isn’t cost…. it’s education One thing you have experienced or have heard about green buildings?
  3. 3. What can we convey through our buildings?
  4. 4. Buildings contribute . . . • Construction and remodeling waste comprises 40% of landfill waste • 48% of energy generated is used by buildings + over 30% of carbon emissions • 66% of electricity is used by buildings + 1/6th of electricity generated is for building cooling • Sick Building Syndrome leads to poor occupant health and loss of productivity
  5. 5. Sick Building Syndrome… …from unhealthy schools can cause asthma, skin and eye irritation, cold symptoms, fatigue, and headaches in both students and teachers. Causes: •Inadequate ventilation •Chemical Contaminates from Indoor Sources •Biological contaminants •Chemical contaminants from outdoor sources Sources:EPA, Indoor Air Quality and Student Performance, YRG Sustainability Consultants

  8. 8. Environmental & Economic Benefits •Energy efficiency •Water savings •High performance lighting •Improved indoor air quality •Emissions reductions Fossil Ridge High School, Fort Collins, CO •Temperature control •Reduced Construction Waste •Lower operations and maintenance costs Kinard Junior High School, Fort Collins, CO
  9. 9. Human Benefits •Student and faculty health •Teacher attraction/retention •Increased student performance •Better focus •Enrichment of learning Bacon Elementary, Fort Collins, CO •Integration of sustainable curriculum •Increased productivity •Connection to nature Islandwood School, WA
  10. 10. Green Schools impact the Community… …and increase awareness about green building
  11. 11. Green Schools Connect to Nature… humans spend 90% of their time indoors isolated from nature… In the U.S., children ages 6-11 spend about 30 hours per week looking at a TV or computer …improving the learning environment
  12. 12. “Our goal is to foster competent, responsible, and independent citizens who love learning and respect themselves, other people and their environment.” Compass Montessori School, Golden, CO = using nature as a model connection for design to nature
  13. 13. Islandwood School, Bainbridge Island, WA This earth friendly school in Washington nurtures and teaches children through the connection to nature (
