The selected comfort zone is for a value of of

Outer range of air temperatures: °C
Given the other four parameters, occupants will find thermal comfort in the wider range of temperatures ( to °C) if can change within the given range.

Inner range of air temperatures: °C
Given the other four parameters, this is the range of temperatures in which all the occupants will find thermal comfort, as long as the is within the given range. The inner range is zero if the comfort zones corresponding to the first and last conditions do not intersect.
