City villa floor plan 160 sqm - Please provide tips!

Well, this wouldn’t be the first survey where the approach is not suitable to establish causality. Ultimately, it boils down to the simple question of what insulates best against heat – in this case ~20cm of concrete or some kind of insulation material. Accordingly, I would probably start by studying the insulation materials.

In view of climate change and the repeatedly expressed fear of heat in other threads as well, I wonder whether it wouldn’t slowly be appropriate to cover roofs in white in the future, instead of the eternal anthracite gray.

In that respect, our roof is deliberately anthracite, yet one must clearly say: it’s the insulation that makes the difference

what about the "Braas Protegon technology" (up to 300% more infrared reflection)???
