项目摘要

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.

本研究旨在利用稻秆木炭进行呼吸墙的利用。这种墙是环境和谐型建筑材料，可以为考虑地球环境和当地环境的建筑做出贡献。在原计划中，应通过调查对申请住宅进行性能评估。但是，在设计阶段，通过听取建筑商或施工相关操作人员的调查，明确了需要通风，热量和湿度的数据来预测性能。因此，本研究的重点转向了设计数据的维护和性能预测技术的发展。具体结果如下：考虑到建筑性质的重要性和环境因素，材料对面板式核心部件进行了改进，朝着利用的方向发展。通过实验掌握了通风性能的特点。并将其收集成可用于设计数据的表格。开发了预测部件热工性能的数值模拟方法，掌握了部件热工性能。结果定量地显示了热回收的节能效果，即使在恶劣工况下，也检查出结露发生危险低。在设计阶段，提出了在申请住宅时计算每年允许换气次数的算法，并对热负荷削减效果进行了计算。通过与自然通风的比较，验证了其节能效果显著。
