協力造屋在設計工作流程上與一般建築工作流程無異，但方案常受限於團隊的營造技術以及設計輔助平台，導致設計想法受侷限。施工方面，礙於技術限制，協力造屋皆採取現地施工，廠內加工的前提必須先以人工的方式繪製所有的加工圖，並反覆校對後方可施工，如遇到方案修改，必須投入大量的人力成本。本研究藉由導入參數化設計工具至果核義築的協力造屋來突破既有的設計方案。 研究過程以果核義築計畫九為研究實驗，使用Rhino以及Grasshopper進行設計整合將前述的設計材料透過參數設計工具推進，並組織協力造屋團隊建造，用以檢視參數設計工具對於協力造屋團隊是否能有效減少工作量以及增加設計探索的可能。

透過設計實踐，參數式工具在設計上確實減少反覆修正的成本與錯誤機率；造型探索（Form finding）上，透過更改參數或參考物件可以快速取得同系列但各自不同的設計方案，並依照先行撰寫的邏輯自動產生每一個版本下的建築元件或單元；加工圖與細部設計可藉由邏輯進行生成，可衍生多種不同的接頭設計，惟目前參數設計工具使用門檻較高，且仍未被大量普及。

研究結果以2020年果核義築的實踐結果與前幾年作品進行多方比較，確認參數設計工具用於協力造屋確實可行，並且值得團隊採用及推廣，同時透過實踐作為建立參數設計應用於複雜幾何木作協力造屋的範例。

The design workflow for Co-Operative Construction is no different from the general construction workflow, the design however, is still often limited by the team's construction skills and design software. The premise for factory processed designs requires all the shop drawings to be first drawn manually and repeatedly the proofread before construction. If the design is modified or revised, a lot of labor and time will be spent on redrawing and checking the shop drawings. Different from the previous CORE projects, the 9th CORE humanitarian architecture project broke through the existing design schemes by applying parametric design tools to the Co-Operative Construction CORE project.

The research process for this research is based on the construction of the CORE project as an experiment. For design development, Rhino3D and Grasshopper3D are used. The design materials are designed through parametric design tools, and the construction team has been organized to complete them. By reviewing the process, this research will identify how parametric design tools can effectively reduce workloads and increase design possibilities.

The results of the 9th CORE project will be compared to previous projects to confirm that parametric design tools are indeed feasible for Co-Operative construction, and that its advantages can be adopted by the project team. Furthermore, this study will establish an example for Co-Operative construction based on parametric design tools designed in complex geometric form with wooden framing.
