BERS doesn’t model in floor heating/cooling systems as such, but the NCC requires an in-slab heating or cooling system, must have insulation with an R-Value greater than or equal to R1.0 installed vertically around the perimeter edge of the slab. The above R-Value reflects NCC 2019 for NCC climate zones 1 to 7. Please ensure you check whether this R Value has changed dependant on the current NCC compliance requirements and/or NCC climate zone requirements.
Insulation can be modelled to the zones once the zones have been fully modelled. A slide bar called "Slab Edge R Value" can be used to select the desired R Value. R1.0 has been selected in the attached example.
Please Note: the slab edge insulation R value can only be added to the entire project. The current limitation of the software program does not allow it to be added to individual zones.
