建築物構件再生理念之探討－以住居建築物為例

姚勝富

[中文摘要]

當全球在生態環境不斷惡化和能源嚴重缺乏的情況下，一個隱藏在經濟因素下的重要觀念不斷地被提出，此即「永續發展」。本研究即在永續發展理念下，以能量觀點出發，探討一有效減少耗能之建築物再生方式。一建築物可視為由諸多構件所組成，當建築物某部位生命週期結束時，僅更換此部位的組成構件為耗能最少的再生方式。而當建築物整體的生命週期結束時，尚可繼續使用的建築構件則應加以轉用以減少資源的浪費。由此引申而來的，即是對於建築物組成構件的生命週期加以安排，以求整體建築物在生命週期結束時，各組成構件之生命週期亦能同時結束。故「構件再生」理念所追求的目標，為耗能的減少與生命週期適當的安排。本研究於構件再生理念下，對再生構法應具備的基本原則加以探討，並以住居建築物為例，分析其組成系統相互間的層級關係、層級關係下建築物生命週期設計以及可能的構件轉用模式，最後提出結論與建議，包括構法原則，系統間層級關係等相關結論，以及後續研究建議。

[英文摘要]

While facing continuing worsened environment and resourceless of energy on earth, an important concept behind economic consider-ation has been lastingly advanced, which is "sustainable developm-ent". The research, based on the concept "sustainable development", was conducted to investigate effective ways to minimize energy cost during the process of building regeneration. A building may be considered as a mixture of lots of building components. When one part of the building reaches its life span, merely replacing the components associated with the part is the way that would have the minimum energy cost. When the whole building reaches its life span, the usable components should be reused to reduce the wastage of resources. As a further consideration, the life spans of all components in a building should be arranged so that when the building reaches its life span, all components reach their life span at the same time. Therefor, the goals of the concept "reuse of building components" are to reduce energy cost effectively and to arrange life span appropriately. The research, under the concept of reuse of building components, is to study the principles of designing building systems, and by takingthe housing as an example, analyzes the level relationship between theassembly systems, the life cycle design under level relationship, and feasible reuse patterns for building components. There are conclusionsand suggestions at last, including the conclusions for the principles of designing building systems, the results of the level relationship between the assembly systems, and the suggestions for future studies.
