每個城市面貌會因為不同的都市計畫與建築法規而有不同的城市景觀。在
台灣，台北是居 住密度最高的城市，土地非常昂貴且居住環境擁擠。量體設計
在整體建築業務流程中為初期設計階段首要工作項目，其設計內容決定了該建
築物基本的面向、建築造型、高度以及各樓層之樓地板面積，在此階段評估建
築配置與陰影是兩個最重要的任務。本研究調查中採訪了資深建築師事務所，
發現在量體設計時，除了符合法規限制，準確的估算出樓地板面積是非常重要
的課題。
對設計者而言，擁有一套合適的設計工具可以幫助他們事半功倍。近年
來，建築資訊建模BIM(Building Information Modeling) 變成AEC 技術核心內專
業人員之間的流行語，包括設計、施工、和建築營運等所有層面。以電腦模擬
分析建築的研究應用，包含建築節能、法規檢核、結構計算、施工模擬等逐漸
成熟。在這些因素綜合考量下進行設計是具複雜性的，設計者未必能在一定時
間內產出多項方案分析並且進行決策。因此，本研究嘗試以衍生式設計工具，
結合無因次参數與基因演算法，建構一個模擬系統進行優化計算，優化結果能
夠提供初期設計階段相關重要資訊，並且幫助設計者在法規限制下找出最佳建
築方案，計算出總樓地板面積。
以實際案例作為操作基地，針對現行台北市建築管理自治條例與建築技術
規則對於集合住宅開發之法規中退縮範圍與陰影計算之限制，提出對應的程式
開發方法與代碼編寫。並且採訪了資深建築師事務所設計流程與使用工具，藉
以比較本研究開發之工具與傳統業界使用之工具的工作效率的差異與優缺點。
操作結果得到了多個最高容積的量體配置方案，其容積數值逼近法規最高限
制。
本研究企圖在初期設計階段複雜的法規限制中，提供一個準確的定量分析
工具，可以更有效率地設計出符合法規的建築量體配置，進一步，可以在一定
時間內產出多個建築量體方案進行優化計算，而產出的模型資訊也能夠交付給
下一個設計階段使用。

The results of urban planning and building codes on cityscape in a city created a distinctive urban scene of the city. As the most densely populated city in Taiwan, living condition in Taipei is crowded while land price is skyrocketing. The manipulation of building massing is a crucial task during the initial stage of architectural design process. Building massing manipulation have some decisive outcomes on, building orientation, architectural style, building height and floor area on each level in case of multi-levels project, and It is important to have real time data for evaluation on the building orientation and shadow profile during this stage. Interviews have been conducted with some experienced architects, and the results suggest that floor area estimation is comparably necessary as complying with the urban building codes.
A set of well-fitting design aids are going to expedite this task greatly for designers or architects. As BIM(Building Information Modelling) is becoming ever popular among AEC(Architecture, Engineering, and Construction) professionals which includes design and construction in the recent years. At the same time, application of computer in simulation analysis is getting ever mature in terms of building energy simulation, building codes evaluation, structural calculation and construction simulation. So, it is rather complicated to work under such a complex integration of all the related aspects, hence, for designers or architects, it is usually quite improbable to produce sufficient schemes for design decision making. As far as this issue is concerned, this research explored the potential of Generative Modelling Application, by integrating the ideas of Dimensionless Grid and Genetic Algorithm, in order to bring out a simulation system for optimization. The result of the optimization is expected to provide important information in the initial stage of design, while assisting designer to define the best building program and sum up total floor area under the circumstances of building codes’ restrictions.
This research proposed a set of methods and programming code for a software tool base on an actual site for a construction project, regarding the restrictions on high-rise housing block development in terms of building setback and shadow profile delineated by the Self-Government Ordinances of Building Administration in Taipei city. In addition, interviews are conducted with the practising architects to learn about the application of design process and design aids in the industry in order to make comparison with the proposed tool at the end of this research, by considering the pros and cons as well as efficiency. The end product of this research is expected to generate different schemes with highest plot ratio with all of them close to the maximum allowable plot ratio.
This research intends to produce a precise design aids that will provide quantitative analysis to facilitate the production of building massing and orientation in an efficient way. Furthermore, generating sufficient amount of schemes or programs within a designated period of time for optimization purpose, subsequently, the model and information produced can be utilized in the upcoming stages of design.
