| Summary: | 碩士 === 淡江大學 === 建築學系 === 91 === Taipei located in north part of Taiwan. It is subtropical climate with clear four seasons. The climate in architecture belongs to sub-heat & moist. The average relative humidity more than 80%. The first priority of architectural design in this area is to prevent moist, dew & ventilation. However, the current business building design seldom implement natural ventilation but with air conditioner. It exhaust natural resources of the earth gradually if solely depends on air conditioner. The air will deteriorate below to live standard swiftly when power failure.
Taipei is the Capital of Taiwan. It goes without saying that the importance to politics, economic. The movement of Taipei influences the trend of other place in Taiwan. So, the Taipei City Hall not only the central nervous of public works of Taipei City but also demonstrate to society. On economic, reconstruction creates benefit of essence application. On the other hand, the benefit couldn’t be counted as a demonstration to society & environment.
The Case study of Taipei City Hall Atrium. To analyze the factor of climate of Taipei including wind velocity, wind direction, temperature & humidity for the latest 10 years to obtain the months that suit natural ventilation. The natural ventilation based on temperature 21.52。C, wind velocity 3.0m/s. To use CFD Simulation to probe into the interrelation between opening mode and ventilate efficiency. We expect to find a better way of opening through the case study to provide reference for prospective designer & user.
The Administration of Taipei City costs approximately $251,300 monthly on the ventilation in atrium. The cost to modify skylight of atrium about $3,466,050. That is to say, total reconstruction expense can be shared in 14 months.
