Financial
Responsibility
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
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
Declaration #4:
“Our integrated thinking will focus on the following
Social Values provided by Concrete Structures”:
1. Resource efficiency
5. By-product reduction
2. Safety/protection
6. Aesthetics
3. Financial responsibility
7. Societal connectivity
4. Operational continuity
8. Longevity/durability
This presentation
discusses Social Value #3:
Financial
Responsibility
Value #3: Financial Responsibility
Concrete structures provide economic
advantages both from a total cost of
ownership perspective, and from greater
local content benefit to communities.

Financial Responsibility:
What It Means
• Investing locally
• Initial and Long
Term Value
• Reducing
operational costs
Local Investment
Local Investment in
Community
The concrete industry creates
local jobs
• In 2005, cement industry
employed 16,877 workers.
• Translates to 1+ million
direct and indirect jobs.

Initial and Long Term Value
Reduced Operating Costs
• Fuel Economy
• Heating and
Cooling
• Heat Island
Reduction
• Disaster
resistance
Financial Value Today & in Future
Concrete roads cost less
For a 1-mile, 2-lane road:
• In 2003, asphalt cost $120k less than concrete.
• In 2009, concrete roads cost $82k less than asphalt.
• Increased cost due to oil prices and refining techniques.

Annual Savings of $1,750 per truck
$4.6 billion nationally
Operational Impact
Precast replaces hand-set brick exterior
with metal-stud back-up.
Project Details
•$365 million
•1.2 million sf
• Integral insulation
• Complete vapor
barrier
UK Patient Care Facility, Lexington, KY
General Contractor: Turner Construction Company | Architect: Ellerbe Becket, Minneapolis, MN and GBBN Architects | Owner: University of Kentucky
Operational Impact
How
• Look of hand-laid brick,
without the cost
• Concrete mass
regulates temperatures
• Walls create air and
vapor barrier (less heat
loss)
• No condensation in wall
Operational Impact - Results
Concrete walls save energy and reduce costs
3 factors contribute to
thermal performance
• R-value
• Air infiltration
• Thermal Mass
Greater R-value, more
energy savings
• Concrete = R 26.98
• Metal stud = R 11.49
Operational Impact - Results
Envelope
Performance
