What is Sustainable Design?

• a system of development that accommodates human needs without diminishing natural resources for future generations to meet their own needs.

Sustainable Design

Perpetual Natural ResourcesVirtually inexhaustible on a human scale

Solar, Wind, Tidal, Gravity

Renewable Natural ResourcesResources that can be replenished through natural processes in a

relatively short time: Water, Timber, Grasses

Non-Renewable Natural Resources

Resources that require thousands of years to replenish:

Coal, oil, natural gas

American College & University Presidents’ Climate Commitment. for the Advancement of Sustainability in Higher Education

Sustainability Initiatives• Commit to building all new buildings to LEED Silver or higher certification. • Purchase Energy Star compliant appliances in new & renovated buildings.• Begin a recycling program • Make energy improvements throughout the campus infrastructure, such as

enclosing open air breezeways, digital controls, energy management system• Pay for print (reduced paper usage in labs by 90%)• Trayless dining in cafeteria• Summer schedule of 4 ten hour days and closing many buildings on Fridays• Participated in the National Teach-In• Flagship campus for Earth Hour• Host Earth Day activities for Girl Scouts• Start a bike sharing program• Promote spsu.zipride.com, a carpool-matching website• Retrofit library to reclaim some of the original design energy saving features• Completed an emissions inventory (improving that calculation with better data)• Create a climate action plan for the University• Integrating sustainability education across the curriculum.
