We have a supplier's documentation spreadsheet for structural steel listing each separate material (HSSs, beams, channels) with weight, cost, post and pre-consumer percentages.

Hello, Our contractor will most likely reuse some waste materials on their other projects if they have any left over.

Does a subcontractor, who is cutting and finishing FSC wood in their own facility and installing it in the project have to be FSC certified?

Hi Everyone, Just to confirm I have this straight: For designated hotel smoking rooms / smoking restaurants / bars / etc.

We have a project pursuing LEED CI and the project team is considering to install laminate flooring which is Greenguard certified but not Floorscore.

Our project team is appealing a denied IEQp1 on a LEED Schools v2.0 project.

My current project contains a non-manufacturing lab and research facility. The entire lab and research facilities probably incorporate a large portion of the buildings overall power consumption.

Our project is located in a new area in which a residential area will be developed in the near future but is not developed yet. Is it possible to count this area for option 2? Thanks!

If the Cork flooring exceeds air quality standards established by SCAQMD rule 1168 - Can we consider that it meets the option # 2 of IEQc4.3 "California Department of Heath Services standard"?
