| Abstract |
Natural ventilation through openings such as windows in school buildings is an efficient resource for natural cooling during the intermediate
season of the year. Because the natural ventilation uses the wind outside the building, the amount of ventilation will depend not only on the
wind speed and wind direction but also on the window layout and open window ratio. Therefore, in this study, the natural ventilation plans
of school classroom windows are divided into 4 types and 8 cases as shown in Table 1. The characteristics of cooling effect by natural
ventilation are simulated by applying Energyplus's Airflow Network Model and the comfort of the occupants is evaluated by the number of
hours included in the 80% acceptability range of the ASHRAE Standard 55-2010 adaptive comfort model for the weekdays (Monday-Friday)
and the class hours (08: 00-19: 00). Based on the analysis results of the above, this study presents basic data related to classroom cooling
plan using intermediate season natural ventilation. |
