8 88 SiteWaterEnergyMaterialsIEQ L E E D L eadership in E nergy and E nvironmental D esign LEED is a third-party certification program and the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.

9 99 LEED Rating Systems

10 10 LEED-NC Atlanta Community Food Bank, LEED NC Silver LEED-NC Program: 7 Prerequisites: Non-negotiable 32 Core Credits:64 optional points Innovation Credits: 5 optional bonus points Levels of Certification: Certified points Silver points Gold points Platinum52-69 points New Construction & Major Renovations

11 11 LEED-NC Point Distribution Sustainable Sites: 14 pts Water Efficiency: 5 pts Energy & Atmosphere: 17 pts Materials & Resources: 13 pts IEQ: 15 pts Innovation & Design: 5 pts TOTAL: 69 Pts Credit Format Each credit identifies: Intent Requirements Technologies & Strategies

12 12 Sustainable Sites Develop appropriate sites Use existing infrastructure Preserve natural areas Reduce need for automobiles Protect endangered habitats Restore polluted sites

13 13 Water Efficiency In the U.S., about 340 billion gallons of fresh water are withdrawn daily from rivers, streams, & reservoirs Water treatment is municipality’s single biggest energy bill (water savings = energy savings) Power plants consume 3 gallons of water per kWh produced (energy savings = water savings)

14 14 Energy & Atmosphere 17 possible points Buildings consume ~40% of U.S. energy (70% of electricity) Fossil fuels produce 3/4 of our energy Coal power plants emit more fine particulate material than any other U.S. activity Natural gas (CO 2 ), nuclear energy (radiation), and hydroelectric power (habitat disturbance) all have negative impacts on ecological systems Efficient buildings reduce pollution & cost and enhance comfort

15 15 Materials & Resources Construction/Demolition waste makes up 40% of U.S. waste Reuse/Recycling saves production & transportation energy & landfill room Salvaged/Recycled content materials minimize the use of finite, declining resources Rapidly Renewable resources minimize impact of natural resource consumption for manufacturing

16 16 Indoor Environmental Quality 15 possible points Americans spend 90% of their time indoors Inside pollutant levels may be 2 to 5 times higher than outdoor levels 17 million Americans have asthma and 40 million suffer from allergies Better IEQ can improve worker productivity more than 15%

17 17 LEED Rating System & Reference Guide LEED Rating System – free, but only minimal detail LEED Reference Guide – explains each credit in detail LEED Reference Guide Version 2.2 Available for purchase Comprehensive Guide to individual Credits/Criteria LEED Rating System Available in a downloadable.pdf file from the USGBC website Contains credit intent, requirements, submittals and technologies/strategies includes the Credit Checklist.

18 18 LEED and the Aggregate Industry

19 19 REMEMBER: Buildings are Certified…… Products are NOT

20 20 Sustainable Sites Credit 6.1 Stormwater Management, Rate & Quantity Decrease stormwater run-off Use permeable concrete OR Pervious hardscape

21 21 Sustainable Sites Credit 7.1 Heat Island Effect, Non-Roof Use light color hardscaping material such as concrete or gravel

22 22 Materials and Resources Credit 4.1 and 4.2 Recycled Content, 10% - 20% Use concrete made with substitute materials such as fly ash OR Use asphalt made with recycled asphalt planings, recycled concrete road base, recycled asphalt road base.

23 23 Materials and Resources Credit 5.1 and 5.2 Local / Regional Materials Manufactured, Harvested & Extracted Locally 10% - 20% Purchase products that were manufactured, harvested and extracted from within 500 miles of the project.
