| Research Abstract |
This research aims at carrying out the Breathing Wall using rice straw charcoal utilization. This wall is the environmental harmony type Building Department material which can contribute to the construction which considered earth environment and local environment. In the original plan, performance evaluation of the application residence by survey was due to be performed. However, it became clear to want the data of the ventilating, heat, and humidity for the performance prediction in a design stage by hearing investigation to a builder or a construction related operating pursuer. Therefore, importance was shifted to maintenance of this design data, and development of the performance prediction technique in this research. The concrete result is as follows.
1. Improvement to the panel-like core component by the material which thought construction nature as important and considered environment was performed towards utilization.
2. The characteristic of a ventilation performance has been grasped by experiment. Moreover, it collected into the form which can be used by making it into design data.
3. The numerical simulation for predicting the thermal performance as a component was developed, and the performance has been grasped. While the energy-saving effect by heat recovery was shown quantitatively as a result, even if it was under the severe condition, it checked that dew condensation generating danger was low.
4. In the design stage, the algorithm which can calculate the number of times of ventilation which lets every year at the time of applying to a residence pass, and the heat load curtailment effect was developed. Consequently, when comparing with natural ventilation, it checked that the big energy-saving effect was acquired.
