1 PrecastAn Eco-friendly option? Jim Lewis, RA, LEED AP ASTM E60 Sustainability October19, 2009

2 LCA and Precast Why is an LCA important? What will PCI and the industry do with the results? Will we be transparent?

3 Greenwash (grenwosh,-wôsh) – verb: the act of misleading consumers regarding the environmental practices of a company or the environmental benefits of a product or service. Source:

4 Truth? Lighter, cleaner and more energy efficient than precast…

5 The process An credible LCA requires: Good data: oManufacturer data (9 precasters); oPCA reports with LCI data on cement and concrete; and oU.S. LCI database (NREL) A good process: oISO oISO Transparency: oExternal review team; and oExperienced consultant.

6 Credible partner LCA consultant –RFP creation –Lit review –Interview moderator Interviewed 3 –Athena/Morrison Hershfield –PE Americas/Five Winds –CIRAIG External review team –Professor, Carnegie Mellon –Berkeley Labs –British Precast Association

7 Outcome

8 Why an LCA? To benchmark industry and back claims RequestsOwners Requirements Congressional Caucus Coalition (hpbccc.org)

9 Comparative analysis 3 partners Phase 1: Comparative analysis Per ISO, specific requirements for disclosed, comparative assertion LCAs. Data for all products must be treated equally and be of similar quality.

10 Building scenarios Envelope and abbreviation Structure and abbreviation Steel (S)Cast-in-place concrete (C) Precast concrete (P) Curtain wall (CW)S-CWC-CWP-CW Brick and steel stud (S)S-SC-SP-S Precast concrete (P)S-PC-PP-P Insulated precast concrete (PI) S-PIC-PIP-PI Insulated precast concrete and brick veneer (PIB) S-PIBC-PIBP-PIB Under Ground Services - (Contain Liquid) - (Keep Liquid Out) Precast concrete only, full LCA

11 New Eco-shape bottle uses 30% less plastic. The new bottle weighs 12.5 grams which is 15% less. Nestle estimates it will save 65 million lbs of plastic with Eco-shape. Cap was blue, which wasnt recyclable. Example: manufacturer changes

12 What do we do with an LCA? Improve our processes Improve our products Improve structures

13 Next steps Phase 2-Building use Transportation products
