I am looking for some feedback on the interpretation for appropriate zoning and controls. It appears that every solar exposure must have a separate control zone. So if I have a men and women's restroom, does that mean I have to provide a individual VRF fan coil for each restroom? Interior spaces must be separately zoned - I have separated the exterior zones from interior zones. I have also made sure that conference rooms, breakrooms, etc are on separate zones. However, if I have (4) interior exam rooms do I have to provide four individual VRF fan coils for each room? Just curious how this is interpreted. Thank You so much!

1. No, you only need a separate control for each solar exposure, not each room on that exposure. 2. Sounds like the interior exam rooms would need separate controls. There may be a way to zone these spaces without having a separate system for each. You can have more than one zone per system.
