Table J-1 Rate Rationale (see Table 6-1) (Continued)

Occupancy Category Description/Rationale

Kitchen Occupant activity is very active (walking, talking, eating, food preparation and cooking). The presence of large quantities of unpackaged, cooking prepared foods creates higher levels of space-related contaminants. The associated food odors results in this space being classified as Air Class 2.

Restaurant dining rooms Occupant activity is moderate (standing, talking, eating, waiting tables). The presence of large quantities of

unpackaged, prepared foods creates higher levels of space-related contaminants. The associated food odors result in this space being classified as Air Class 2.

Occupiable storage rooms for liquids or gels

Occupant activity is primarily sedentary (seated) The concentration of stored products increases the level of spacerelated contaminants. Current ventilation rate is consistent with other minimal/transient occupancy environments.

Hotels, Motels, Resorts, Dormitories

Barracks sleeping areas Occupant activity is primarily sedentary (sleeping). There are no significant space-related contaminants. 5 2.5 0.06 0.3 1

Bedroom/living room Occupant activity is primarily sedentary (seated or sleeping). There are no significant space-related contaminants. 5 2.5 0.06 0.3 1

Laundry rooms, central Occupant activity is primarily moderate. There are often usual space-related contaminants related to cleaning. 5 2.5 0.12 0.6 2

Laundry rooms within dwelling units

Occupant activity is primarily moderate. There are often usual space-related contaminants related to cleaning. 5 2.5 0.12 0.6 1

Lobbies/prefunction Occupant activity is primarily standing and light walking. However, occupants are generally more vocal, resulting in higher metabolic rates. There are no significant space-related contaminants.

Multipurpose assembly Occupant activity is primarily sedentary (seated or light walking). There are no significant space-related contaminants.

Miscellaneous Spaces

Banks or bank lobbies Occupant activity is primarily standing and light walking. However, occupants are generally more vocal, resulting in higher metabolic rates. There are no significant space-related contaminants.
