Hi All,

I am wondering if anyone has any experience with the following type of
modeling in equest.

The building I am working on is an apartment building where they are
planning to install a variable refrigerant flow system with rooftop
heatpumps. The refrigerant will be routed from the rooftop to individual
airhandlers in each apartment. I don't think equest has this as one of
their system types, and I think the closest thing would be a packaged
terminal heat pump. The apartments all meet ASHRAE requirements to use
natural ventilation, but as I understand it equest does not allow natural
ventilation to be used with this system type. Have I passed over a better
option for modeling this system, or does anyone know how I could include
natural ventilation in the model. From what I've read it looks like I'll
have to create another model for natural ventilation and use the exceptional
calculation method.

Thanks in advance.
