Hi,
One of our clients is considering the possibility of certifying a new airport terminal using LEED and asked us to perform a preliminary evaluation of the potential LEED score.
According to EA C1 (“ Enhanced Indoor Air Quality strategies”), permanent entryway systems shall be installed at regularly used entrances. Our proposal is to classify as regularly used entrances all those that are used by the public, including:
- terminal main entrances (through which passengers, workers, etc. will enter and leave the building);
- all entrances between the building and the ... used by passengers to access / return from airplanes (e.g., access to airport buses, direct walking access to airplanes, etc.).
All other entrances are for staff use only and will not be considered high traffic entrances (please note that this terminal will not include enclosed carparks), thus exempted from the requirement to install permanent entryway systems.
Do you agree with this interpretation ?
Best regards!

Hi Ricardo,
Our firm is working on a number of different projects at an airport and our assumption with terminal facilities is as you said in the assumptions for 1 and 2. A regularly used entrance is one that is used frequently as a means of gaining access to a building.
My working assumption with staff entrances are that they must also meet entryway requirements, however this could easily be met with rollout mats or carpet tile designed for entryway systems.
We anticipate receiving receiving confirmation of our approach around January or February 2019 so can keep you (and others that might be interested) apprised once we receive feedback.
Also, LEED is now catering more to airport project types so if you need additional resources, those can be found here for your preliminary evaluation: https://www.usgbc.org/articles/airports-and-leed-what%E2%80%99s-new

Hi Matthieu,
Long story, short - not yet. We were anticipating submitting this credit during the design phase for one of our Terminal projects and ended up being delayed for the construction phase review in 2021.
I did find this other LEED User chain on regularly used exterior entrances, where the threshold is daily use. This would mean that staff entrances would also be required to meet the credit requirements: https://leeduser.buildinggreen.com/forum/regularly-used-exterior-entrance

I agree with Allan that any entries used by staff during their typical daily tasks would need to meet the requirements as they will be tracking in moisture, dirt, or "pollutants" from the outside. We've seen a v4 project where the reviewer required 10' walk-off mats at an door that connected an office breakroom/ cafe to a small outdoor patio area with exterior seating. Staff would be re-entering the building at that door but it was not used as a primary entry to the building.
My impression is we can safely exclude doors used for fire exits, or access doors to spaces such as equipment rooms or storage that are only accessed occasionally.
Hope that helps.
