Cool roofs have many benefits, including to boost aircon efficiency and make solar work more efficiently. So why is this being ignored in Australia's major cities?
The only explanation would be an attic (any air gap) &/or high quality insulation between the roof and living area. If you have solar (incl pool), that would divert a lot of heat too.
Dogshit insulation, reasonable roof space + sarking. Gets v toasty in the room that has less roof space even though we did the insulation there with high quality stuff so maybe it’s the air gap?
have solar actually. Not over the one warm room. Maybe it’s that combo!
Good thoughts. Also fuck I wish we double glazed windows. It gets to like 4 degrees in my bedroom over winter nights.
That’d do it! Double glazing and high quality insulation should have been the minimum requirement for every new build this century. Not a fucking add-on. All these shitty pro-industry regulations do is shave 1% off the cost of new builds, and transfer that to a 50-100x larger expense in energy over the life of the structure. Our building standards are fucking criminally corrupt and incompetent.
Yeah lol of course solar is gonna make your house colder. The Sun’s rays are made of photons with a certain amount of energy. That energy can either turn into heat, or it can turn into electricity. Solar panels turn 20% of the energy into electricity instead of heat.
