I am researching option 1 for Advanced building requirements. We are working in a 1 story industrial park and are installing new 10 ton and below DX RTUs. We are meeting all the efficiency requirements, but I am uncertain if 3.10 Variable Speed requires VRV system? Or is a constant volumn DX RTU design acceptable?

If your individual unit fan motor horsepower is greater than 5 hp then you would need to comply with 3.10. If less than 5 hp make sure to point that out in your documentation.

I have a similar issue where the pollution control in the unit is a constant volume fan and needs to be that way for exhaust and pressure requirements. We don't have a VAV fan that is 5hp or more. Do we document this in Special Circumstances?
