LEED Points and any resulting certification can apply only to a finished building. There is no such thing as a LEED certified product. The architect working on a LEED certified building will be asking all his suppliers to provide products that contribute to his total LEED points. It will be up to the supplier to document how their product contributes in a certain LEED point category. A case can be made that concrete can contribute in whole or in part to 25 of the maximum 69 LEED points in LEED NC version 2.2 . However, with architectural precast products, the obvious contributors will be recycled content and sourcing within 500 miles. The architect will add up the dollar value of all the recycled content of every component of the building and determine whether the total building meets a 10% (1 point) or 20% (2 points) recycled content threshold. Similarly, if 20% of the value of the building components are sourced within 500 miles, another point is earned. If 50% is within 500 miles, two points are earned. The LEED certification standards are evolving and increasing focus will be placed on maximizing LEED points attributes in every category possible.
