Extension of the PMV model to non-air-conditioned buildings in warm climates.

States that the PMV model is in good agreement with high-quality field studies in buildings with HVAC systems, located in cold temperate and warm climates, which were studied in both summer and winter. Occupants may sense the warmth in non-air conditioned buildings in warm climates as being less severe than the PMV prediction, probably because of low expectations or because too high an estimate of metabolic rate. Introduces an extension to the model which includes an expectancy factor to be used in non-air conditioned buildings in warm climates. This extended model is in good agreement with quality field studies in non-air conditioned buildings of three continents.
