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
48%
U.S. Energy Power Consumption by Sector
U.S. CO2 Emissions by Sector
76% of all
power plant generated electricity is used just to operate buildings !!

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.
