Resource Efficiency Joint Sustainability Initiative
2
The Joint Sustainability Initiative (JSI) is a multi-association effort of the Concrete Industry supply chain to take unified and integrated action for Sustainable Development
3
JSI members have signed a joint agreement committing to act on 9 Declarations. Declaration #4 addresses 8 Social Values of Concrete Structures http://www.concretejsi.com/about/declaration.HTM http://www.concretejsi.com/about/declaration.HTM
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

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
