3. Desiccant Wheel can already be modeled (object = DESICCANT 
DEHUMIDIFIER:SOLID) 

A model for an enthalpy recovery wheel (latent + sensible) should be 
included in the next release (Version 1.1). 

A model for CO2-based demand ventilation is coming later this year.  
In the meantime, you can simply schedule the outdoor 
ventilation air using the same schedule you use for occupancy.  This 
will at least give you a first-order approximation. 

Please clarify what you mean by runaround loops:  sensible heat 
recovery from exhaust air to preheat incoming ventilation air,
or air-to-air heat exchanger used to improve the dehumidification 
performance of a cooling coil. 

I'm not sure about the status of the other areas.
