I have not seen this question about base/subbase addressed here yet. I have read the comment fill materials are part of 31 2000 Div.

We have used large quantities of waste materials procured from manufacturers. We have procured waste material like broken bricks form the brick manufacturer.

Can select fill mined within the LEED boundary be counted as a regional material?

Hi all, we have building where the tenant is installing the entire energy related system (ACMV, lighting, etc). The landlord only provide land and structural of the building.

We have a registered LEED ND v2009 project. Our SSLc4 does not comply (we are shy of the needed short-term bike racks and showers).

Buildings LCA is conducted to measure the impact of building materials..as well as building use etc.

GoO (Guarantees of Origin) are European equivalent to United States' REC.

My sustainability consulting firm has been conducting the con docs (drawing) reviews for our clients for LEED compliance, but the method we have been using is not the most streamlined.

Does the compliance with the ISO 14025 standard automatically include cradle to gate scope? Or is the scope stated separately in the product EPD?

Please, someone knows where can I buy the Integrative Process (IP) ANSI Consensus National Standard Guide© 2.0? In ANSI's webstore I found v1.0 only.
