My project has apartments and penthouses on the top. Engineers design VRF with thermostat and residents can control their comfort thermally. I'm wondering how to document for this credit: do I just need to write a narrative that thermostat is available in every room and residents can control air speed, humidity, temperature to match their clothes and activities in the room so resident can have the best thermal comfort. Or I have to show PMV/PPD result for residents. If I have to do so, I will use thermal calculation tool for appartment as a whole or for every single room (bedroom, living room, kitchen room.
Thank you

You should be able to comply. Either do a calc for a typical unit, or show that the MET rate allows you to use the "standard" comfort zone, and that the VRFs can meet temperature and humidity requirements.
Should also document the air speed - VRFs can be "blowy"
