Hi, Would a room containing a 3D Printer and Laser Cutter be considered a hazardous gas and chemical use area? Thanks for your help!

This is an eight-story apartment building that is pursuing LEED-NC 2009 and contains future retail spaces in the ground floor.

Hello, Could the exhaust of a high-density copy room be achieved via a 100% exhaust base building system?

LEED v3 reference guide has mentioned that 'the exhaust rate must be at least 0.5 cfm per square foot, with no air recirculation'..does it mean exhaust system or AC system???

Have there been any exceptions to the walk-off mat length requirement when vestibules are located at an exterior entry?

Working on a project that the occupancy of the building is a multi-tenant.

In the new version of the LEED online template for this credit, there is a minimum (with doors closed) and average required pressure differential in Pa.
