| Popis: | 102 Ever since the late twentieth century has global economy grown rapidly, which brings the acceleration of urbanization, rapid growth of population, massive development of land, and high concentration of energy consumption. This study focuses on the influence a city’s layout of its buildings and open areas causes to its thermal environment. Also, a Physiological Equivalent Temperature (PET) model will be built in order to illustrate the assessment and design tactics for buildings and open areas in future cities. The study helps figure out factors of correlation between open space and thermal environment so that a specific data base can be established, according to which we are able to proceed analysis of variance and multiple regression analysis, whose results can be adopted to correlation analysis. Then finally, a thermal environment evaluation model will be built in accordance with the result of this study to ultimately provide planning and strategy for the arrangement of a city’s buildings and open areas. Furthermore, the model can serve as reference to the goal of constructing a visionary city and ecological environment. Meanwhile, the research was conducted simultaneously with the other study that examines open space thermal environment of Taichung City, which locates in the mid area of both Taiwan’s geographic and climate distribution. Accordingly, we are able to achieve a better understanding the thermal perception of residents and their expectations toward thermal environment. The examination performed during February 2013 and November 2013 helped us collect totally 855 questionnaires from various school campuses, and a thermal environmental climate factor test was also performed in certain locations. The result of the examination shows: 1. Open space like school campuses can be evaluated based on SVF value. The larger the SVF value, the higher the average temperature. 2. Closed space shows lower temperature during high-temperature period while a U-shaped space with smaller square and SVF tends to be influenced more easily by thermal radiation and thus shows higher average temperature. 3. The larger the square of an open space, the higher the average temperature. We observed that when certain space with 1000 square meters were exposed to thermal radiation for certain period of time, the temperature could reach 40 degrees Celsius. 4. Occupants in those campuses are most satisfied for thermal perception and expectation when PET is at 26 degrees Celsius, which is the medium. The result proves that the layout of campuses is influential to its open space.PET 26 degrees Celsius is the medium of this research, which can be referred to when it comes to outdoor exterior design, and it is helpful to reach the best thermal environmental comfort. Key words: Urbanization, open space, thermal environment, Physiological Equivalent Temperature (a.k.a. PET). |
