The Traditional College Student
Environmental Awareness in General2007 Gallup Poll
• 77% of Americans worry “a great deal” about the environment
• 83% have taken concrete steps to reduce energy use
• 40% have donated money to an environmental group
• 90% of Americans recycle
5
The Traditional College Student
90% of Americans Recycle – But how much?
6
The Traditional College Student
Environmental Donations are a small part of Overall Giving
7
The Traditional College Student
83% of Americans have taken concrete steps to reduce energy use?
Could that possibly be true?
Probably!

Sustainable Education
Baseline.com lists “Green Guru”, dealing with sustainable technology and operational efficiency, as the 9th Hottest Career Opportunity
Pew Charitable Trusts indicates the number of jobs in clean energy economy grew nearly 2 ½ times faster than overall jobs in the last decade
An EPA report indicates that “Environmental Education enables individuals to develop critical thinking, problem solving, and effective decision making skills”.
The Association for the Advancement of Sustainability in Higher Education (AASHE) lists over 120 4-year Universities with undergraduate programs in Environmental Studies/ Environmental Science

Productivity/ Attendance Increases
• Three independent studies by the Technical University of Denmark indicated that the performance of simulated office work improves with air quality
• EPA reports that improved IAQ in schools can reduce absenteeism, improve student productivity and performance, improve student and staff concentration
• A study published in the Journal of Indoor Air reported a 13.7% increase in reading test scores and a 14.7% increase in math test scores with improved air quality.
24
Productivity/ Attendance Increases
• Minimum IAQ Performance• Tobacco Free Campus• Ventilation Effectiveness• IAQ Management Plan • Low Emitting Materials• Thermal Comfort• Daylight and Views

The Business Case
We’re now ready to go to our College Business or Chief Financial Officer and make our case for sustainable construction:
• Our students expect it• We can use it as a teaching tool• It will increase productivity and decrease absenteeism
And he’ll say…….
How Much Does it Cost?
31
The Business Case
Money Saving Construction Features
• Construction Waste Recycling• Local/ Regional Materials• Reduction of Water Usage• Plumbing Fixtures• Water Efficient Landscaping
• Energy Savings Features
32
The Business Case
Construction Waste Diversion
At both Wildwood and Harrison, well over 75% of construction waste was diverted from landfills.At Wildwood, it was 95%!
Wildwood
Harrison Center
33
The Business CaseWater Efficiency
Wildwood and Harrison Center use low flow fixtures, realizing a 30% reduction in water usage, and have no landscape irrigation systems.At Wildwood, rainwater is captured to water the small areas not planted in prairie
34
The Business Case
Local/ Regional Materials
At both Wildwood and Harrison, 20%+ of materials come from within 500 miles of the site.
35
The Business Case
40% of the Energy in America is consumed by buildings
Energy Use
36
The Business Case
Energy Saving Construction Features
• Building Commissioning• Design to Energy Standard• Optimize energy Performance
through selection of equipment
• Monitor System Operation• Address heat island effect• Utilize natural lighting where
possible
37
Building Commissioning
• Commissioning ensures that building systems and equipment provide peak performance
• A study of 60 commercial buildings found that more than half suffered from control problems.
• Three case studies show savings for building commissioning• The Chattanooga State Office realized a 20-month
payback on their commissioning activities• Parkway Fountains Office Building in Phoenix
estimated their savings after commissioning at 15% of their annual utility costs
• Westin Hotels invested $100,000 in commissioning their new Seattle hotel and realized a $300,000 savings over the next eight years
The Business Case

The Business Case
Design to Energy Standard
USGBC requires LEED buildings to meet ASHRAE energy standards as a prerequisite

Optimize Energy Performance
Wildwood predicted a 30% plus energy savings over conventional buildings using DOE modeling
Harrison Education Center predicted a 30% plus energy savings over conventional buildings using DOE modeling
