Field Study of Thermal Comfort in Naturally Ventilated Classrooms of Cameroon
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 5
Abstract
Thermal comfort is an important factor in a classroom. This paper presents the results of a field study campaign in three classrooms of the University of Yaounde I in Cameroon. An adaptive approach was used. The questionnaire was formulated according to the adaptive and statistical model prescribed by UNI EN ISO 10551. Various values of air temperature, wind speed, and relative humidity were measured at the same time students were filling the questionnaire. The study was conducted during three seasons (little rainy season, little dry season, and great rainy season). Several correlations were established according to the model of Fanger (PMV, PPD) and that of Wray. The temperatures of neutrality for the three seasons were found between 23.4 °C and 25.7 °C. The vote of thermal acceptability showed that during the three seasons, 66.02 % of the students found their environment acceptable, while the votes of thermal preference were: “want warmer” during the little rainy season, “want no change” during the little dry season and “want cooler” during the great rainy season.
