碩士 === 國立臺灣科技大學 === 建築系 === 103 === 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.
