Try the UnitVentilator model, using the minimum amount of cooling for the day time and the outdoor air ventilation as economizer.
The outdoor temperature is monotored to control the amount of air flow into the OA mixer inlet node

Matt,
As a means to estimate effectiveness of nighttime ventilation, you could create a ZoneVentilation object that only comes on at the appropriate time (night, summer, etc.) using a schedule and when the outdoor temperature is within a certain range. The limitation to this is that you'll need to carefully choose the range of dates so that ventilation doesn't cause unecessary daytime heating.
Hope that helps...
