predicted mean vote

Metabolic heat production is one of the key parameters in maintaining the body’s heat balance with the environment. Levels of accuracy and methods for estimation of metabolic rate for various activities are given in most of the commonly used standards, and estimated metabolic rates for an average adult are tabulated to be used where direct measurement is not practical. However, determination of metabolic rate is expected to be different in a younger population compared with that of adults.

This study evaluated the thermal environment in an air-conditioned mosque in Malaysia during the various daily prayer times. The objectives of the study includes determining the clo values, the neutral operative temperature, comfort temperature, and assessing the reliability of the PMV model predictions in determining thermal comfort in these situations. A field study was conducted in November 2012 and April 2013 during Subuh, Zohor, Asar, Maghrib and Isyak prayer times. Results show that PMV model predictions and AMV were found to be 25.88 °C and 30.44 °C, respectively.

The vote of acceptance of the thermal conditions of a built space varies with the individual. The design of the space should consider the occupant's thermal comfort therefore the future users' opinion on thermal conditions. People's opinion regarding the acceptance of thermal circumstances of a room can be expressed by several indices the PMV the scale being the most used for this purpose.
