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.

本研究旨在利用稻草炭开展呼吸墙利用。该墙是环境和谐型建筑系材料，有助于考虑地球环境和当地环境的建筑。原计划是通过调查对申请住所进行绩效评估。然而，通过听取建筑商或建筑相关运营方的调查，很明显需要通风、热量和湿度的数据来进行设计阶段的性能预测。因此，本研究中的重点转移到了设计数据的维护和性能预测技术的开发上。具体结果如下： 1．重视建筑性质并考虑环境的材料对板状核心部件进行了改进以实现利用。 2．通过实验掌握了通风性能的特点。并且将其收集为设计数据，形成可供使用的形式。 3．开发了用于预测部件热性能的数值模拟，并掌握了其性能。结果定量地显示了热回收的节能效果，即使在恶劣的条件下，结露发生的危险性也很低。4．在设计阶段，开发了一种算法，可以计算申请住宅通行证时每年允许的通风次数以及热负荷削减效果。因此，与自然通风相比，证实获得了较大的节能效果。
