| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 95 === This thesis aims to investigate application of ventilation strategy based on “Night Ventilation” concept in a building which is located in subtropical monsoon climate. In order to improve the maximum indoor temperature and the delay of the maximum indoor temperature of the building under no air-conditioned situation, the natural ventilation or the mechanism ventilation strategy is used in the building.
The simulation building in the thesis, NTUST-1, is a two-floor house located in Tu-cheng City, Taipei County. The house is used as the prototype house for the simulation study. The first part of this research focuses on the setup of the geometry, the materials and internal arrangement of the building. ‘Energy Plus’, building energy analysis software, is used to simulate the building under different conditions, such as varied heat capacity, different types of windows, indoor sunshade equipments and different air change rates per hour when night ventilation is applied. The thesis presents the indoor temperature performances under the different arrangements.
The simulation results show that prototype house uses low heat capacity materials, so it is unable to effectively store heat in its structure. In addition, the prototype house has many windows and that causes plentiful solar radiation heat inward the indoor environment. When the indoor environment is not properly ventilated, the indoor temperature may exceed the external ambient temperature by 10~15℃.
When the night ventilation strategy is applied, the raising of indoor temperature in the morning can be delayed by 1 to 1.5 hours. If we do not consider significant changes of the building structure of prototype house, it has been shown that we can reduce the maximum indoor temperature through the changes of windows and indoor sunshade equipments.
