近年來舊建築再利用的討論在空間議題上多集中於再利用的使用類型與設計策略的可能性探討。對於舊建築透過再利用的設計概念、設計手法及工程技術改建後，所要彰顯的無形價值卻鮮少有深入的討論。本論文希望藉由台灣舊建築再利用案例的研究分析，進而從設計的層面，探討舊建築延續生命週期的初始目的與具體價值，即非實質層面的無形價值，透過再利用後是否不變甚至有加分效果，以及再利用之後所呈現出的當代社會意涵，以協助台灣舊建築再利用論述之建立。
　

研究的對象有三點限制：一、不包含古蹟，二、經由再利用後必須具開放性意象或是開放為大眾使用之舊建築，三、必須是公開發表過具有保存意義的舊建築。探討的焦點有三：一、舊建築物保存價值的界定，二、價值彰顯的設計手法分析，三、各案例經再利用手法處理後所產生之共通與差異之現象。
　

綜合本研究分析得知，目前台灣舊建築再利用後呈現過度強調現代性意涵的現象，主要呈現均質性的美學手法與概念、營造都市中的交流空間與環境的凝聚力。在改善空間使用品質下掩蓋了舊建築主體的原始存在意義，同時，再利用空間計畫多為表象性定向、缺乏完整性定位。再利用後所呈現的社會意涵與集體記憶往往以歷史價值、日後的使用效益以及公共性活動為主，舊建築存在的意義僅侷限於本身的歷史意涵、大眾文化與消費娛樂。

Recently the topic about reusing old buildings focuses on the exploration of reuse which is about classification and strategies of architectonic. After reuse, the emerging value of old buildings from ideas, methods and technologies that is still lacked to exploration. This paper starts in series of case studies and questions if the initial aim of preserving old buildings, the value, increases and the emerged contemporary social meaning. These studies lead to the establishment of the thesis of reusing old buildings in Taiwan.
　

The cases are chosen the following three principles： The first, the chosen building cannot be the Monument Building； the second, it should be a public building after reuse； the third, it must be made known to the public and worth to be reserved. Moreover, the exploration focuses on three points which are the definition of old buildings' value, the method of emerging value and the possible merits.
　

The previous studies indicate the reuse of old buildings in Taiwan. It emphasize the meaning of modernity and presents similar esthetics and ideas overly. However, these improve the quality of environment and space, but they focus on the emphasis of contemporary appearing, they cause the original meaning of old buildings will be cover. Moreover, the reuse programs focus on the building itself instead of the context and integrated configuration. The new generated invisible value focuses on history and future benefits but ignores economy. It only presents the contemporary trends instead of values based on real requirements. At last, the meaning of old buildings only limit on the historical value, the popular culture and entertainment.
