That TeachBrian Dunbar, Exec. DirectorInstitute for the Built Environment

The biggest issue in green building infusion isn’t cost….
it’s education
One thing you have experienced or have heard about green buildings?
What can we convey through our buildings?
• 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
Buildings contribute . . .
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•Biological contaminants
Sources:EPA, Indoor Air Quality and Student Performance, YRG Sustainability Consultants
•Chemical Contaminates from Indoor Sources•Chemical contaminants from outdoor sources

Green Schools impact the Community…
…and increase awareness about green building
Green Schools Connect to Nature…
90% of their time indoors
humans spend
isolated from nature…
…improving the learning environment
In the U.S., children ages 6-11 spend about
per week looking at a TV or computer
30 hours
Compass Montessori School, Golden, CO
“Our goal is to foster competent, responsible, and independent citizens who love learning and respect themselves, other people and their environment.”

A Sustainable Future…“We have lived by the
assumption that what was good for us will be good for the world. What is good for the world will be good for us. We must:– make the effort to know the
world and to learn what is good for it.
– abandon arrogance and stand in awe.
– recover the sense of the majesty of the creation, it is only on the condition of humility and reverence before the world that our species will be able to remain in it.” Wendell Berry
