A study on the environmental performance into standard system of elementary school building by wood-frame construction method-outline of model plan and field measurements of thermal environment in winter.

This study is concerned with a standard design of an elementary school by a wood-frame construction method. The purpose of this study is to adopt environmental adjustment techniques such as the use of indoor lighting and a thermal environment in the elementary school setting. In the model plan, a dual-layer wall arranged on the outer-wall side with the structural strength necessary to support a three-story school building was devised with a buffer space between the walls. In this report, for an environmental performance inspection of the buffer space, the authors utilized an experimental building to perform actual indoor thermal measurements during the winter season. The results were as follows: due to the warm air ballooning from the outer periphery of the experimental room's floor surface into the buffer space, both the floor and walls had a higher surface temperature. Compared to the inside of a room without such a buffer space, the area close to the outlet of the double-layered floor showed a temperature difference of 12°C. Furthermore, there was a 2 to 5°C difference in the lower temperature areas of the respective walls. This experiment elucidated the environmental performance gained throughout the inside of the experimental room by the establishment of a buffer space.
