I would like to know how you can consider a concrete which has returned to the production plant without being used in the construction. Can be a residue pre or post consumer? Thanks.

We are currently working on a multiphase development in which the foundation of one building is being completed while another is being demolished.

Has anybody ever had an issue with using an EPP certified product to gain recycled content for a project?

It is obvious that the LEED reviewers use a set of predetermined comments for certain material claims made.

CSI Section 10 is included in this credit. What would be considered toilet/bath acessories under CSI 10 28 00?

When working on large projects with substantial mock-ups, should one include these materials in the project documentation?

Our project in Guam used base material extracted on site and gradated for reuse as aggregate sub-base below slabs and pavement on site.

We receive letters from suppliers and manufacturers documenting the recycled content of the materials, but not declaring the cost per item.

Can Division 2 materials (hardscape, storm/sanitary utilities, landscaping) be excluded from the overall material cost when calculating for this credit?
