Select comfortable summer design conditions (dry bulb and relative humidity) for a machine shop where people in light clothing (clo = 0.5) will be engaged in active work such as ham-

A supervisor who is much less active than the other workers will occupy a space in the same environment. What is your suggestion for maintaining his or her comfort?
