Table 1.

Air temperature design ranges (ΔT) of thermal indices meeting criteria C1 to C7. Ranges of wind speed in persons height (v) or 10 m (v10), relative humidity (RH), and mean radiant temperature (Tmrt) are indicated as far as documented in the original publications. Air temperature ranges have been taken from de Freitas and Grigorieva (2016)
