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

Bacon Elementary, Fort Collins, CO

Islandwood School, WA

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.”

This earth friendly school in Washington nurtures and teaches children through the connection to nature (www.islandwood.org).

Energy and Atmosphere

•Cooling system makes ice at night when energy costs are 60% lower•HVAC: Small, 97% efficiency boiler unit•Photocells monitor amount of light needed from interior fixtures•Booster heater at dishwasher reduces hot water system load•100% of electricity use is offset through green power

“We raise the bar for construction and design with every school we build or remodel. Our new elementary schools are scoring in the 80’s (on a scale of one to 100) on the EPA Energy Star bench marking system.”

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
