 ASHRAE 55-2017 defines the Cooling Effect (CE) at elevated air speed (above ) as the value that, when subtracted from both the air temperature and the mean radiant temperature, yields the same SET value under still air (0.1 m/s) as in the first SET calculation under elevated air speed .The CE can be used to determine the PMV adjusted for an environment with elevated air speed using the adjusted temperature, the adjusted radiant temperature and still air ().Where the adjusted temperatures are equal to the original air and mean radiant temperatures minus the CE.
