Ensuring delivery of a strong environmental message and demonstration of how concrete building and pavement apply to the USGBC's widely embraced LEED rating system, a contingent of national material and product operators and five trade groups participated in the 2007 Greenbuild International Conference and Expo, Nov. 7-9 in Chicago. Expo attendees noted demonstrations or announcements from:
- National Ready Mixed Concrete Association and Interlocking Concrete Pavement Institute, which deployed water tank-style displays to demonstrate pervious and permeable paving methods, both holding LEED point value.
- Holcim (US) Inc., St. Lawrence Cement and Aggregate Industries announcing a call for Holcim Awards/North American Region entries, plus expanded participation in two climate change programs (companion item below).
- Portland Cement Association, advancing the recently adopted "Concrete Thinking for a Sustainable World" message releasing urban heat island effect study findings favoring concrete pavement (companion item below).
- National Concrete Masonry Association and Precast/Prestressed Concrete Institute, providing information on architectural possibilities, plus thermal efficiency and site-waste reduction factors, tied to specification of block or precast walls and load-bearing members.
- Oldcastle Architectural, promoting new permeable pavement units and single-wythe structural CMU with water leakage control. Other national operators showing premium concrete pavement and wall products were Hanover Architectural and Wausau Tile.
