Flooring is roughly 15%. Properly insulated slab (edges + bottom) will be behaving well from the perspective of thermal comfort (to the extent that you can comfortably walk barefooted over tiled floor in the winter morning). Same thing applies to the properly insulated suspended slab too, but if it is not a concrete slab, you won't be having a thermal mass effect there, yes. Secondly, properly designed house with thermal mass and well insulated from all the points, would not even require instant changes in comfort - the heating and cooling will be only needed to be applied for short periods of time during extremely hot or cold weather streaks only. Otherwise, 8-12 hour thermal lag due to insulated thermal mass will be able to keep inside temperatures in comfortable range by itself. Thirdly, previously I found that BASIX assessments have no idea of insulated thermal mass effect and in their models brick veneer walls insulated to R2.8 are behaving exactly the same as double brick or ICF walls insulated to the same R value. Which is obviously far from reality, first because brick veneer with calculated R2.8 will be performing to R2.0 at best due to thermal bridging caused by the studs and inconsistency of insulation installation, secondly insulated thermal mass walls will still be thermally performing much better even with the lower R value insulation. Re: Any info on new Basix since July 2017 and using raised f 5Sep 09, 2018 9:19 am I agree with you. The problem is that you can no longer specify your insulation requirements using the online tool to compensate for the loss or gain in the thermal sections. This can only by someone who uses a nathers approved program in which you need to pay 500 dollars to get a certificate for the thermal section of the basix. I would a stacker door going to the covered deck, but thermal comfort dictates I either have a normal door, or no cover over the deck to get winter sun. Even thermally broken, double insulated doors don’t cut the mustard on the online assessment. It dictates the minimum requirement of r2 for walls and r3.5 for ceiling even though I am well above that using a better design/insulation combination and can’t add this to the tool. 0 2020 Broker here - legislation says that every true broker must put the clients best interests before theirs so in theory they must offer you the best options for you on their… 2 46012 CDC Housing Code 3 When to apply Floor Area external face of wall vs Gross Floor Area internal face of wall.
