Thermal comfort, what is that?
Comfort is part of the Passive House programme: The requirements of the Passive House standard automatically ensure that all comfort criteria are optimally met – considerably better thermal insulation also improves thermal comfort:
Better thermal insulation (regardless of the external component) reduces the heat flow from inside to outside.
Therefore, the heat flow from the interior to the inner surface of this exterior component is also lower. The heat flow overcomes the so-called heat transfer resistance of the surface (radiation and convection).
The lower heat flow results in a lower temperature drop over this heat transfer resistance, in other words: the temperature difference between the room (the surfaces in the room and the air in the room) and the inner surface of the better insulated component decreases.
