How important is choice of flooring for optimizing solar gain?
We are building in (I believe it is) zone 6, Cranbrook B.C.
We are working on trying to get the right ratio of floor to window area on the south face. Trying to comprehend the various factors such as amount of direct and indirect sunlight onto the different surfaces and how that effects the ratio.
How important is the choice of flooring? I understand that a dense mass such as 3″ of concrete/tile might be the best choice however the others involved are leaning towards 3/4″ hardwood (Hardwood on conc slab in the walkout bsmnt and on plywood subfloor on 1st floor)
When calculating floor area do we include the rooms separated by walls and doors? (bedrooms and bthrms along the north side) What about a kitchen on the north side open to the south facing main area?
Thanks for info on these questions and any good info on this specific area of design.
