AHU's serving process spaces

If we have AHUs serving rooms with low temperature and humidity below the requirements for human comfort, can these be excluded from the mandatory and prescriptive requirements of ASHRAE 90.1 2007 as they are serving a process function rather then a human comfort function?– Then can a project comply with the minimum energy performance prerequisite by complying with the mandatory and prescriptive requirements for all other AHUs excluding this process AHU? Or would you have to go through the section 11 route for all AHUs? Again, Thanks in advance
