Verified Ventilation and Filtration

Verification Method

The evaluation for this Verification is conducted in two parts: Part 1: Base Building Review The building owner or operator shall submit the documentation necessary to confirm their space or facility's ability to meet at least 2 effective air changes per hour (eACH). The UL Solutions team will review mechanical schedules, cutsheets, HVAC system design and zoning, installed filtration media, etc. to verify the inputs for the ASHRAE eACH calculations. Part 2: SafeTraces Data and Results Review The base building review will also validate the Part 2 testing plan for high density areas space determination and sampling strategy. For Commercial Office Buildings, defined as a building primarily or exclusively containing leased or occupant-owned office space, the criteria for high-density areas are as follows: (1) enclosed; (2) ceiling heights 12 feet or less; (3) with a population density >1 person per 200 square feet; (4) that are occupied on average by two or more people; and (5) 15 minutes or greater average occupancy time per person. This may include but not be limited to conference rooms, cubicle areas, break rooms, lobbies, etc. All Part 2 testing result data will be rigorously reviewed to ensure the spaces are meeting stated claims. Empirical verification is required for at least 10% of all high-density areas defined above and include a minimum of 2 locations per space type. The verification must show the high-density areas achieve >99% hourly aerosol removal based on aerosol tracer-based field results. The areas verified shall be randomly selected (i.e., unbiased selection) from the identified high-density areas.
