Program OverviewProgram Overview
Selling Precast in a Green World
The audience for this program are sales and marketing professionals engaged in the direct sales of precast concrete products.
This program is not meant to replace experience in selling precast but to further educate and add to the tools to make a convincing argument for the use of precast concrete in sustainable green design.
Program OverviewProgram Overview
Selling Precast in a Green World The green building market and GreenWashing
Green certification, codes and standards
Selling to sustainable minded architects
How precast contributes to sustainable design

“Meeting the needs of the present, without compromising the needs of future generations to meet their own needs.”
What does Sustainability Mean?What does Sustainability Mean?
GREEN is changing the
way products are sold,
marketed, and developed.
Truth aside, everyone claims to be green Increasing number of “green” building
materials/products Product features and benefits are
manipulated to reflect green attributes

What NOT to say: “LEEDS”
“Precast is green”
“Precast can guarantee LEED points”
Never make unsubstantiated claims
Competing systems “are not sustainable or green”

Green building accounted for about 10 billion dollars in 2005In 2009, despite an overall construction downturn of 25%, green building grew to $60It is expected to reach over $70 billion in 2010And, green building is expected to reach upwards of $135 billion in 2015It is a steadily growing percentage especially fast growing in government and school markets.
Designers specify hundreds of systems/products per project
Limited knowledge of products/systems Time constraints Illusion of an organized up to date library Path of least resistance; they come back to
the products/systems they know
Selling to Sustainable Minded ArchitectsSelling to Sustainable Minded Architects
Sustainable construction involves an integrated design team.
Holistic approach to building design Adjust and shift budgets to meet goals Make trade-offs to improve overall design Get on the team early in the process Collaborate and solve problems vs.
pitching products.

Remember – Most Designers know more
about green building practices…
but you know more about precast systems.

What’s wrong with LEED?
High costs of registration/certification Complexity and bureaucratic requirements for
certification Lack of rigor in the rating system Lack of lifecycle analysis after certification Potential risk/litigation when not achieved “Self Administered” resulting in subjectiveness

Steel and recycled content
Oxygen Furnace process uses 25%-35% recycled steel.
Electric Arc Furnace process uses 90%-100% recycled steel.
Post-consumer and post-industrial recycled contents provides 15-20% LEED™ value for BOF and 75-90% recycled content for EAF.
Most North American structural steel are produced using EAF with 90% recycle content.
Steel industry is improving its sustainability
Improved recycling and reuse since the turn of the century
Reduced energy consumption & CO2 emissions by 20% since 1990
Great efforts are being made to create and understand the sustainable potential of steel

Data you should collect:
Document raw materials origin. Document pre-consumer and post-industrial
recycled content of each. Possible recycled content by material:
- Rebar 80-90% - Forming materials
- Insulation 90-100% - Formliners 85-95%

limestone. Fly ash replaced 30% cement. Slag lowered density
concrete (125 pcf vs.150 pcf). Reduced weight allowed more
panels per truck. Lighter weight results in
savings in foundation construction.
Walls have 3- to 4-hour fire rating and R19 energy rating.
