説明

 Monitor roofs can promote natural ventilation, but it is not easy to predict ventilation flow rate through a monitor roof because of its variable resistance depending upon a number of factors such as wind velocity, wind direction. To predict flow rate through monitor roof, its ventilation characteristic must be arranged in advance, which is expressed as a correlation between internal pressure and flow rate; i.e. p-Q curve. By using dimensionless ventilation characteristics obtained in the previous work, this paper focuses on the flow rate of realistic residential building under various meteorological conditions, which has almost never been evaluated before. This paper presents wind tunnel measurement to obtain Cp value, and calculation of annual ventilation flow rate based on simplified estimation method using ventilation characteristics. Assuming several cases of ventilation path aiming for ventilation or cross-ventilation, ventilation performance is evaluated.
