I am working on a LEED certification for a new building that is attached via a small circulation bridge to an existing LEED-Certified building on a college campus.

We are currently using the Hilti CFS-TTS Firestop Top Track Seal for one of our projects. The VOC Content is 22g/l. Under what category should I enter this product for IEQ c4.1?

Are roofing materials part of this credit? Do I need to take into consideration the VOC Content of the TPO Bonding Ahesive, TPO Cut Edge Sealant, TPO Primer and the TPO Seam Cleaner?

I am working on a project where i have a control room to monitor the users activities for security purpose. There are 7 seats.

Does an EPD need to be issued before the manufacturing date of the product installed? Or do we just need to provide an EPD for that product when we submit for certification?

I am working on a project where i have retail units in a big building which serves the building users. These retail units will be rented so we are not sure how the seat arrangements are.

Hello, does anyone know if it is aceptable to use sri values of concrete from the guide for a crusher fine concrete or it need a test to be accepted? Thanks

Hi everyone: I have a Project that needs to have large retention walls close to the office and main acces road.

For a Multi-Fam Highrise, the corridors will be heated with a ducted roof-top gas furnace split dx system will be installed.

Our Project is a Campus Project with 4 registered buildings for LEED. The ground cover landscape didn't not meet the SS C5.1 requirement. So we opted for Roof Garden on one of the buildings.
