An air conditioned office is occupied by 4 persons. Two of them, wearing suits with a thermal resistance of 1.1 clo, are engaged in managerial activities generating metabolic energy at the rate of 1.6 mets. The other two persons, wearing lightweight clothing with a thermal resistance of 0.65 clo, are working at computer terminals for which the metabolic rate is 1.1 mets. Determine the optimal air temperature for the office.
