Re: [EnergyPlus_Support] Purchased air problems

[Fred Buhl <wfbuhl@xxxxxxx>]

Marzia,

In the case of PurchAirTable it is most likely due to the
lack of any infiltration and to the solar gain through an unshaded
south facing window. The internal gains (people, lights, equip) are
in the normal range.
