1. Resource Efficiency

2. The Concrete Joint Sustainability Initiative is a multi-association effort of the Concrete Industry supply chain to take unified and integrated action for Sustainable Development

3. Concrete JSI members have signed a joint agreement committing to act on 9 Declarations. Declaration #4 addresses 8 Social Values of Concrete Structures http://www.sustainableconcrete.org http://www.sustainableconcrete.org

4. Declaration #4: “Our integrated thinking will focus on the following Social Values provided by Concrete Structures”: 1. Resource efficiency5. By-product reduction 2. Safety/protection6. Aesthetics 3. Financial responsibility7. Societal connectivity 4. Operational continuity8. Longevity/durability

5. What it means Concrete Structures over their lifecycle are efficient users of energy, water, land and other resources Social Value: Resource Efficiency

6. Materials Resources  Durability  Recycled Content Energy Resources  Locally acquired  Structures and pavement Water resources  Pervious pavements Resource Efficiency

7.  Cost savings by not finishing floors, walls, etc.  Structure, air barrier and finish in one integrated system  Easily repairable Resource Efficiency Photo courtesy of L. M Schofield

9. Integrated Design = Success!

10. 4,000 psi vs 9,000 psi concrete?  Additional 3,120 rentable square feet  16% less cement  1,730 yards less concrete  3,400 tons less weight Reduce CO2 by 220,000 lbs Design Flexibility / Optimization

11. Ryerson Conservation Center, Lake County, IL 60,000 gallon concrete cistern provides both Fire Protection & Thermal Storage Multi-tasking Material

12. Energy Resources Did you know? Average distance between manufacturing and project site is only 14.2 miles?

13. Concrete roads:  Minimize urban heat island effects  Have lower rolling resistance  Require less fuel during construction Energy Resource Efficiency

14. Concrete bridges and other infrastructure  Durability  Accelerated construction schedule  Reduced maintenance Resource Efficiency

15. Land and Water Resources

17. Reduction of floor and wall finishes  Improved thermal comfort  Reduced sound transmission  No food source for mold growth Resource Efficiency

18. 125+ million tons/year Cradle to Cradle

19.  Integral waterproofing  Photo-catalytic concrete  Nanocements  Seawater-based cement and aggregates Looking Forward

20.  New supplemental cementitious materials, such as rice husk ash  Light-transmitting concrete  Carbonation research Looking Forward

21.  Fundamental to sustainability for future generations  Durability and efficiency affects both maintenance and replacement  Extends beyond construction materials to include water, land use, and energy Summary
