| Research Abstract |
1. Questionnaire survey to teachers was carried out teachers. A classroom in summer is fairy hot, and that in winter is very cold. These are originate in the condition of inlet solar radiation and cross-ventilation. There are many problems that is not able to solve with only passive method in hot summer. Even indoor air quality problem was pointed out with the windows shutting up in winter.
2. According to the results of short-term measurements, classroom temperature nearly equal to outside temperature when window is opened in summer. The difference of glove temperature between that on north side seat and that on south side seat was appeared to about 2℃. There is not obvious difference of the temperature in two types classroom, the fragment corridor type and the middle corridor type. SETィイD1*ィエD1 goes up and thermal sensation is hot in the case of middle corridor type classroom.
3. According to the results of long-term measurements for 1 year, the number of lecture hours when classroom temperature exceeds 28℃ in summer equal to about 10% of all lecture hours in a year. In case of winter the number of these hours when the temperature less than 18℃ equal to about 30% of all hours. Classroom environment is influenced by opening and closing the window or curtain, also the direction of window face. Especially air quality problem happens with the window closing in winter.
4. The results of questionnaire survey to a board of education scattered main city in Japan were discussed. Heating equipment was established in a classroom usually in about 70% of cities of the whole. On the other hands the cooling equipment is not established fundamentally irrespective of an outside temperature without the special case.
5. Hearing survey and inspection regarding classroom environment was carried out in domestic and overseas cities. Those characteristics was summarized comparison with the case of Fukuoka-city.
