This research is to propose a new technique for General Commissioning (performance verification) of house ventilation system based on the purpose of energy saving and preventing sick house syndrome. And this research was implemented for the development of operation support and assessment tools that are essential for Commissioning.It is obliged to install mechanical ventilation facilities in houses and draw out a numeric statement of the planning stage by the revised Japanese Building Standard. However it was revealed that the air flow rate of ventilation system was below the requirement of 0.5 ACH in many existing houses.For the General Commissioning technique, the assessment method of each stage was studied according to the assumption of the performance verification of planning, installation and operation stages.The ventilation planning simulation tool developed as the assessment tool of planning is able to estimate the ventilation rate easily by substituting openings. In the case which requires essential detailed analysis, a hybrid technique was developed. This technique can calculate ventilation rate between nodes using COMIS and air flow in the room by CFD for Macro and Micro analysis.For the measurement method of installation and operation stages, we operated the examination of measurement and numerical analysis for the actual and experimental houses. And we analyzed the selected and application method to meet the measurement conditions such as types of house and ventilation system and situation of house, in terms of items, equipments, periods of measurement, application condition and load of the house owners.Finally the General Commissioning of the ventilation systems of the actual houses was examined. The cost for the Commissioning and the training of the Commissioning Engineers is the key to the prevalence of the General Commissioning of the house ventilation system.

本研究旨在提出一种以节能和预防宅病为目的的住宅通风系统总调试（性能验证）新技术。这项研究的实施是为了开发对调试至关重要的操作支持和评估工具。根据修订后的日本建筑标准，有义务在房屋内安装机械通风设施，并制定规划阶段的数字声明。然而，调查显示，许多现有住宅的通风系统的空气流量低于0.5 ACH的要求。对于一般调试技术，根据规划阶段、安装阶段和运行阶段的性能验证假设，研究了各阶段的评估方法。开发的通风规划仿真工具作为规划的评估工具，可以通过替换开口处方便地估算出通风率。在需要详细分析的情况下，开发了一种混合技术。该技术可以通过COMIS计算节点间通风量，并通过CFD进行宏观和微观分析。对于安装和运行阶段的测量方法，我们对实际房屋和实验房屋进行了测量和数值分析的检验。并从测量项目、设备、测量周期、使用条件、业主负荷等方面，分析了满足房屋类型、通风系统、房屋情况等测量条件的选择和应用方法。最后对实际住宅的通风系统进行了总体调试。调试费用和调试工程师的培训是住宅通风系统全面调试能否普及的关键。
