Question
Which strategy is an example of permanent entryway systems used to reduce dust, dirt and contaminants brought into a facility?
A. Providing sensors at all entrances
B. Conducting a thermal comfort survey
C. Installing outdoor air monitoring equipment
D. Placing grilles, grates or mats at all major entrances
Answer
D. Placing grilles, grates or mats at all major entrances
Explanation
Permanent entryway systems are designed to capture dirt and particulates entering the building at regularly used exterior entrances. They can be grilles, grates, mats or other materials that are at least 10 feet long in the primary direction of travel. They can improve indoor air quality, reduce maintenance costs and enhance floor appearance.
Installing permanent entryway systems such as grilles, grates or mats at all regularly used exterior entrances is a strategy employed in LEED buildings to capture dust, dirt and contaminants from entering the building. These systems work by scraping debris off of shoes and collecting it in the mat or grate, preventing it from being tracked further into the facility.
This helps improve indoor air quality and reduces the need for cleaning, thereby lowering maintenance costs and chemical use. Entryway systems are required for certain LEED credits related to indoor environmental quality.
The other options, while relevant to other LEED strategies, do not describe permanent entryway systems:
A) Sensors at entrances could be used for occupancy detection but not for reducing contaminants entering the building.
B) Thermal comfort surveys assess occupant satisfaction with temperature but are unrelated to entryway debris.
C) Outdoor air monitoring assesses outside pollution levels but does not prevent dirt from entering through doors.
Therefore, placing grilles, grates or mats at entrances is the only listed strategy that serves as a permanent entryway system to trap contaminants, making D the correct answer. Employing this technique can help projects earn LEED points while creating healthier and easier to maintain green buildings.
