LEED and the Steel Fabricator
Construction Waste Management

1 additional point for diverting 75%
by volume or weight
1 exemplary performance point for diverting over 95% from the landfill
or MR Credit 4
1 point for using at least 10% recycled content by cost

1 exemplary performance point for using at least 30% recycling content by cost.
The LEED Point System
I get asked all the time about what the LEED rating system means and what the steel fabricator has to do to comply.
Though it sounds mysterious to many of us, it is simply a point rating system for the Leadership in Energy and Environmental Design program, commonly referred to as LEED. This voluntary program first began in 2000, and is run by the US Green Building council, or USGBC.
Steel is a very sustainable material, as it is created from recycled products. After the job is finished, the scrap is then returned to be recycled yet again. Steel erected on site offers little waste on the job.
What the design team needs is documentation to verify the percentage of the purchased product that was made from recycled materials as well as what was diverted from the landfill. Recycled content is measured both as post-consumer recycled content and pre-consumer recycled content.
The recycled content value of each product is determined by multiplying the cost of the product times the recycled content of the product. They then take all the recycled content values, add them together and divide that by the total cost of materials used in the project to determine the points achieved.
Points are also gained for products manufactured, processed and extracted regionally. A steel fabricator located close to steel rolling mill would have the advantage here.
One might check with the contractor they are working with to find out what kind of documentation they need for this verification, if any. Other than offering copies of the mill certifications, providing the weight of materials sent to the scrap bin may contribute to the cause.
Everybody is going green.........
