Region: NT
Assessor Question:
I have been asked to provide NatHERS certificates, to a number of coastal NT remote area housing projects (climate zone-1).
The skillion section below, shows roof ventilators with a damper. I have asked the Architect for clarification, on the function of these vents.
If they do penetrate the ceiling and as they will have sealable dampers fitted, can they be assessed similar to an exhaust fan sealed?
TechLink Response:
NatHERS does not deal comprehensively with thermal chimney ventilation.
If this vent is intended for that purpose the benefit will not be fully modelled by the energy rating.
At the moment a sealed exhaust fan is the best fit data selection
