When metabolic rate is above 1 met, the tool automatically adds the air speed generated by physical activity (e.g. walking) to the measured air speed, following ASHRAE 55.

Disable this if occupants are at elevated metabolic rates without generating air movement (e.g. exercising on stationary equipment).
