建築空間的使用需求(所需提供的服務內容與水準)隨著社會發展而不斷異動,這項變遷是因使用者對建築空間的使用需求會改變。為要應用BIM(Building Information Modeling)技術模擬使用需求改變所帶來的影響,需要一個具有可調控參數(變數)的BIM模型。然而現階段的BIM模型,屬於靜態的建築資訊模型,也就是建築模型所儲存的參數資訊,如幾何或建材等資訊,只能是常數。例如,在模擬使用者在建築物內的活動時,可能會受到建築空間內如門的開關、手扶梯的速度等因子所影響,因此,如何在BIM模型中提供一個可表達可調控參數的方式,是本研究的目標。 為了能進行可變參數的空間使用模擬,本研究使用資料庫、windows form視窗技術及建模軟體的應用程式介面(Application Programming Interface,簡稱API),開發儲存和管理BIM模型可調控參數的平台雛型。首先,本論文舉例了哪些應用情境模擬需要有BIM模型可調空參數,再分析平台在功能上如何滿足應用情境的需求,然後進行平台的實作與應用展示,最後討論平台的延伸應用。
There are human flow simulations done on buildings for civil use. These simulations are carried out to test the performance of escape routes designed in buildings. However, buildings as simulation environment use in these simulations are static information models, which means that building models used as simulation environments can only provide building parameters information which cannot be modified, such as building geometrical information. As human flow simulations are pedestrians’ movement in a building, the facility such as the doors or the escalators of the static information models does not explain the effects of the facility’s state to the pedestrians’ movement; for example, the opening or closing of the doors can affect the movement of the pedestrians. Unfortunately, the static information models does not provide such parameters. Therefore, this research uses a database, windows form and a modeling software’s application programing interface to develop a platform to store and manage such parameters on a building model. The platform is used to store the parameters of the building models such as the opening or closing of doors, the operating speed of the escalators, and the related parameters that affect pedestrians’ movement. Overall, these parameters of the building facilities are variables. The way of the parameters storing in the platform makes the building models used as simulation environment no longer a static information model, but with variable parameters. By recording the platform’s parameters, the platform becomes an information exchanging tool for all adjustable parameters in the lifecycle of the building.
