62.1-2010, Table 6-1, includes ventilation rates for ôSports arena (play area)ö and ôGym, stadium (play area).ö Both space types have ventilation rates based on floor area only, the per person rate is zero. Users of the standard have expressed interest in applying demand controlled ventilation to these space types, which is effectively prohibited by the lack of a per person component to the ventilation rate. This proposed addendum replaces both of these space types with ôGym, Sports Arena (play area)ö, with Rp = 20 cfm/person and Ra = 0.06 cfm/ft° and assigns this new space type with an air class of 2 rather than class 1 from the first publication public review version.
