08. Healthy entrance
Occupants often track harmful contaminants indoors, including bacteria, heavy metals, lawn and agricultural pesticides, among other toxins. In addition, as occupants walk through entry doors, potentially polluted air can enter the building. Both of these modes of introducing outdoor pollutants to the indoor environment highlight the need for measures that minimize or prevent the introduction of potentially harmful substances to indoor spaces.
This feature requires methods to help prevent pollutants from entering a building. Requirements include floor systems that capture pollutants from shoes and strategies to reduce airflow from the outside to occupied indoor spaces.
To capture particulates from occupant shoes at all regularly used entrances to the project, one of the following is installed and is maintained on a weekly basis:
One of the following is in place to slow the movement of air from outdoors to indoors at the main building entrance:
The following must be present in all facilities adjacent to an exterior grass sports field, if present:
