title: [Survey on microclimatic condition of classroom].
abstract: The results of a research, in winter and spring, on the microclimatic parameters and lighting in eighteen classrooms of primary schools in the town of Messina, are exposed. In a significant number of classrooms values of temperature and relative humidity are registered not in accordance with Italian standards. Thermal indices (PMV and PPD) showed, in both seasons, discomfort conditions in many rooms. A percentage of dissatisfied persons, significantly higher the 10% (56.8% in winter and 70.3% in spring), has been obtained. We used, also, a questionnaire modified by Fanger to evaluate the thermal subjective sensations of the students. The results point out that the thermal subjective sensations expressed by the students are often in disagreement with the Fanger thermal comfort indices obtained by instrument. The authors believe that the Fanger's indices do not reflect the effective environmental conditions.
