[EnergyPlus_Support] Re: V2.2 Infiltration input option

["krgowri" <gsgowri@xxxxxxxxx>]

Linda - Thanks for the quick response.  Based on the recent 
sensitivity analysis we have done with DOE2 linear wind speed 
coefficients, I would suggest the flow rate per exterior area be 
represented as flow rate per exterior wall area.  For anyone 
interested in providing a total exterior surface area, they could 
always use the flow rate per zone floor area option.
