Green Star Credit 7: Construction Environmental Management, and Credit 9: Indoor Air Quality are considered partially equivalent to WELL Feature 07: Construction Pollution Management.

Remove: "Permanent" from title of Part name.

Where projects are restricted from using an entry vestibule or revolving door (for e.g. projects in the Philippines following the National Building Code, which prohibits revolving doors or vestibules for designated exits), they may use a permanent entryway system 3 meters long, and an air curtain to create an air seal. There are several specifications for this path:
1.       The air curtain must have a minimum velocity of not less than 2 meters per second (6.56 feet per second) at the floor, have been tested in accordance with ANSI/AMCA 220, and must be installed in accordance with manufacturer's instructions. It must also be commissioned prior to occupancy by a qualified agent.
2.       An indoor pressure sensor must be installed in the building lobby that is capable of providing automatic readings at least once an hour.
3.       The project team must specify target pressurization levels for these locations when the building is occupied. These levels have to keep air from entering the building more than the standard amount, allow occupants to open and close doors easily and not cause moisture problems due to exfiltration. Projects must provide documentation of these targeted levels and ensure they achieve the objectives outlines above.

Projects must also provide indoor pressure sensor readings from one day. This should include exhaust and supply sequences. Projects should also provide mechanical drawings of the project space and manufacturer documentation of the air curtain equipment.
