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木炭进行呼吸墙的研究。该墙体是环境协调型的建筑系材料，有助于兼顾地球环境和当地环境的建筑。在最初的计划中，将通过调查对申请住所进行绩效评估。然而，很明显，需要通风，热量和湿度的数据，用于设计阶段的性能预测，通过听取建筑商或建筑相关的操作追求者的调查。因此，重要的是转移到维护这个设计数据，并在本研究中的性能预测技术的发展。具体结果如下：1. 2.以建筑自然性为主，考虑环境因素的材料对板状核心构件进行改进，使其实用化。通过实验掌握了通风性能的特点。并将其收集成可供设计使用的表格，制成设计数据.开发了用于预测作为部件的热性能的数值模拟，并掌握了性能。其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，也确认结露的危险性低.在设计阶段，开发了适用于住宅时每年允许的通风次数和热负荷削减效果的计算方法。通过与自然通风的比较，验证了其节能效果。
