Indoor Archery Range - Outside Air

[Mech]

'09 IMC

What do think is the appropriate outside air requirements for an indoor archery range? Right now we're looking at using the "Game arcades" under the Sports and amusement section.

Thanks in advance.

Arcade games have a higher heat output than an archery range would have.

i would think about the same as a retail space ( for air quantity, heat etc) we have onen back home that's in the shop where the store is, big store, off to one side the "small range is walled off from the rest of the establishment, in the back there is a 3d shoot room with really "hunt like" videos. it'a all one system (air/hvac) i'd guess

The proposed layout is approximately 10,000 sf 3D range, 5,000 sf Video and 20 yard range, and 5,000 sf storage, workroom, and sales area. Building heating and cooling loads are easy to determine. I just was not sure of the OA requirements.

I would have thought that Arcade game areas would have a higher CFM rate.

As you already know, the lowest ( besides "zero") rate in the whole table is

5 CFM.

What will the Occ. Load be for this archery range?

I am betting that any method that looks at the whole square footage will overestimate the actual occupant load for OA purposes.

Perhaps bowling alley is closest - Table 403.3 only has you calculate the seating area, the lanes themselves are not considered. If there is an obvious firing line, then perhaps the downrange area need not be considered. This still may end up with a high number at 40 people/1000 sf.

The right answer, would be to apply the exception to 403.3 "The occupant load is not required to be determined based on the estimated maximum occupant load rate indicated in Table 403.3 where approved statistical data document the accuracy of an alternate anticipated occupant density."
