It is well known that radiation is a significant thermal environmental parameter, and operative temperature (OPT) is more closely related to human comfort than dry-bulb temperature. Thermal environmental design in office space, however, has not aimed at making OPT an object which should be controlled directly. The reason is due to the difficulty in practice, and hence, two methods of reducing thermal radiation in office space have been designed and tested, so that the thermal environment can be reasonably evaluated and controlled merely with dry-bulb temperature. The effects have been examined through field investigations and reported in this paper.
