本文介紹臺灣地區建築物外殼及空調系統節能設計現況統計資料，及節能設計規範 基準建議值。內政部營建署與建築研究所為配合國家節源政策之需，而分別研擬建築物之節 能設計規範與基準， 以建築物外殼耗能量 ENVLOAD 為外殼節能設計規範指標，以空調耗能 係數 PACS 為空調系統節能設計規範指標， ENVLOAD 與 PACS 基準之訂定係由成大建築研 究所以實驗計劃法，針對各類建築物進行理論統計分析而得。另外本文搜集臺灣地區各類既 有之建築物，其中包括辦公廳類 41 棟， 觀光旅館類 11 棟，醫院類 7 棟，分析計算其外 殼與空調系統設計之 ENVLOAD 與 PACS 值。 由統計結果分析臺灣地區建築物節能設計之優 缺點與形成原因。其結果顯示建築物之外殼設計實際計算值呈常態分布，接近於理論分析值 。大幅提高了節能法令基準值的信賴性與合理性。另外空調設計方面，結果顯示出臺灣地區 空調設計有超大設計傾向，由此可知臺灣亟需空調方面之節能設計規範與基準。

　　　　　In this paper, the analysis results of the Energy Conservation Desing of Buildings Envelope & Air Conditioning System will be introduced and the standard pattern of Energy Conservation Design will be suggested. The standard pattern announced by The Ministry of Interior is researched by The Graduate School of Architecture, Cheng-Kung University using experimental design method to analyze various buildings. In addition, three kinds of existing buildings data including 41 office buildings, 11 hotels, 7 hospitals were collected to calculate the ENVLOAD & PACS values. The results of ENVLOAD values show that the distribution of those values is very close to the theoretical values. It means that the standard pattern of ENVLOAD are reliable and reasonable. On the other hand, the results of PACS values show that 1/3 of those air conditioning systems are over designed. This fact reflects the necessity for regulation of energy conservation management.
