- e ===== The question of low-energy buildings overheating in summer "due to their high level of insulati... cs: **insulation does not "create" any additional heat**; it only reduces the heat exchange between systems with different temperatures. Therefore, it also protects a cool system from gaining heat from the surroundings. For this reason, cooling
