| Abstract: | It is important to know how to balance the energy saving with the improvement of a learning environment in existing classrooms. This paper shows the influence of window glass specifications (area, U-value and Solar heat gain coefficient) and air-conditioning conditions (preset temperature for heating and cooling) onto the annual heat load of the school classroom. As a result of numerical calculations applying the Taguchi method, main points and effects to select the window glass and the air conditioning condition are shown as follows. 1) The influence of the preset temperature for heating is the largest in the area north than Osaka. 2) In the selection of glass performance in Sapporo, Morioka, Niigata, Osaka, and Fukuoka, U-value is more important for energy saving than the solar heat gain coefficient. 3) The influence of the window area is smallest in these 5 factors. 4) The low lapse rate of energy consumption would be expected from about 20 to 90% by the best selection of window glass and the air conditioning preset temperature setting. 5) An annual heat load presumed by Taguchi-method using SN ratio considering all 5 factors becomes smaller by about 30% than the load calculated by SMASH in the most suitable conditions. |
