Knowing that all floors are airconditioned,

My project is registered as v4 and is using the v4.1 credit substitution for Low-Emitting Materials.

We are having a tough time getting the costs from our subs. The subs says that the cost is bundled with other material and they can't break it up.

What is the correct registration process for certifiation in a building that will contain a data center underground and above ground will serve as office space

Instead of demolition or deconstruction, this project will move an entire building across the street to another site on the campus.

LEED v4.1 references ASTM standard E2813 Standard Practice for Building Enclosure Commissioning regarding BECx requirements.

The product that our sub uses is "Diatrex Transparent Knife Grade" & Axson Cream Hardener"  for stone countertop seams and it does not meet the limits.
