ABSTRACT Estimating thermal comfort temperatures in outdoor spaces provides valuable information that can be used to generate design proposals whose environmental conditions ensures thermal comfort for the users. This study shows the estimated neutral temperature and thermal comfort ranges during the warm period in a public recreational green area located in a desert climate. It was carried out in Mexicali, Baja California, Mexico. A questionnaire was designed based on the scale of thermal sensation of ISO 10551, and measurements of dry bulb temperature, gray globe temperature, relative humidity and wind speed were taken. A total of 822 questionnaires were applied during the months of July and August 2008. The neutral temperature and comfort range were estimated using a statistical method of correlation. The analysis was undertaken for three activity levels, passive, moderate e intense, as well as for the three levels together. The neutral temperature values were approximately symmetrical with respect to the thermal comfort range. They also indicated that intensely active subjects who exercise regularly and have habits that are appropriate to the weather conditions had a comfort temperature similar to that of more passive subjects.

    ABSTRACT: The international standard dealing with thermal comfort, ISO 7730, is presented. The limits specified in the standard are based on accepted percentages of dissatisfied occupants. The philosophy behind the standard as well as the scientific basis are discussed. Recent thermal comfort research results are quoted.

    ABSTRACT: One of the uses of ISO 7730 (predicted mean vote, PMV) is to predict the thermal sensations of people in buildings. This application is examined, using the ASHRAE database of field-studies. Taking these world-wide data as a single distribution, PMV is free from serious bias. There exist, however, underlying biases in relation to all contributing variables, and a further bias related to the outdoor temperature. These biases often combine to produce a substantial bias in PMV. In surveys of individual buildings, PMV often differs markedly and systematically from the actual mean vote, both for naturally ventilated (NV) and for air-conditioned (AC) spaces. Possible origins of the biases are discussed, and it is shown that it would be possible to modify PMV substantially to reduce them. Environmental consequences of the use of PMV are discussed. It is concluded that ISO 7730 in its present form can be seriously misleading when used to estimate thermal comfort conditions in buildings.
