In winter, when temperatures drop, in an uninsulated house, the walls will be at 12°C, if we heat it to 24°C, we will have a felt temperature of 18°C. Whereas in a passive house at 20°C with walls at 18°C, the felt temperature is 19°C. 4°C less to heat for a better feeling.
In short, in a passive house, given the low dependence of the walls on the outside environment (via insulation), the perceived temperature is always higher than that of a less well insulated building heated to the same temperature. Hence a significantly increased comfort at the same temperature.
