> I have 21 myself at home and often get complaints it's too cold. (eastern europe) This is because the air temperature is only one component that determines how warm one feels: > The importance of the MRT can be illustrated by something we’ve all experienced. In an older home in the middle of winter, the ambient air temperature indoors can be 68 to 70 degrees [F], and yet we feel cold when we’re near a window. That’s because the cold interior pane of glass in that window is literally sucking warmth away from us, or, to put it more accurately, our bodies are emitting heat to that cold surface, which causes us to feel cold. This is the inverse of the experience of feeling warmed by the sun outdoors on a cold winter day. Our skin has high emissivity and absorptivity, meaning we’re very sensitive to radiant heat loss and gain. * https://blipdesign.com/blog/passive-house-2/mean-radiant-temperature-an-important-factor-in-comfort/ https://blipdesign.com/blog/passive-house-2/mean-radiant-tem... * https://en.wikipedia.org/wiki/Mean_radiant_temperature https://en.wikipedia.org/wiki/Mean_radiant_temperature * https://en.wikipedia.org/wiki/Thermal_comfort https://en.wikipedia.org/wiki/Thermal_comfort
