Assessor Question:
I was just wanting to confirm a scenario I have at the moment. I have a store room that has been added under a house that is not accessed through the house but by a small door under the house. There is no penetration through to the home. Does this need to be modelled or can be just treated as a void under the floor? The project was already rated a year ago but they have decided to add some storage under the floor and when discussed with the building surveyor he wasn't sure if it needed to be modelled.
TechLink Response:
- The overriding understanding is always to consider heat flow potential through external surfaces into and out of zones within the rated envelope.
- Adding a zone under the house will reduce heat flows through the floor above the store as compared to it being sub-floor space.
- The store can be included as an unconditioned zone and the rating should improve.
- The Building Surveyor may be satisfied with the understanding that the rating will not be lower than the earlier certified result.
