Zoning: Ensuite question.

Region: All States

Assessor Question:

When ceiling mounted vent for heating & cooling has been nominated in a bathroom, that room could no longer be considered an unconditioned room? It would become a daytime zone. Is that correct?  

The same vent is in the Ensuite, would this make it a daytime zone too? 

TechLink Response:

• The inclusion of documentation that indicates fixed heating and/or cooling reticulation as part of a total dwelling system servicing bathrooms triggers the requirement for those rooms to be zoned as conditioned spaces even if they have openable windows. 
• Ensuite bathrooms accessed through a bedroom are night time conditioned zones regardless of whether they have windows or fixed heating/cooling systems.
