大型空間類建築節能法規修正基準之研究

Research on the Dynamic Standard of Building Energy Conservation Code for Huge Space Buildings

大型空間類建築物納入建築節能法規評估體系已逾3年，其包含之建築物種類為現行節能法規六大類別中最多者，且為提升居民生活品質，大型空間類建築個案無論公私部門，近年來均有增加的趨勢，而大型空間類建築外殼設計AWSG(Average Window Solar Gain)現行基準乃依照建築立面開窗率而採「階梯性」的基準設計，由於基準寬鬆、漏洞過多、高低級距基準不公，無法掌握節能成效，近年來頗受評議。本文以動態基準的觀點出發，以創設之迴歸公式作為AWSG動態基準，在不增加建築從業人員工作量的前提下，確實地將基準「動態化」，徹底消彌原階梯基準的漏洞，並且賦予高低級距更合理的基準規範，同時能適切掌握大型空間建築窗而日射取得量，而該適用北中南各氣候區之三組共六條迴歸公式之重相關係數，最低者亦達0.94以上，證實其為可行之解決方案。再者，動態基準對於建築立面設計抵擋日射能力較佳者，在計算AWSG動態基準值將產生高估（即優待）的效應，即對於節能設計較優的建築物將有實質的鼓勵效果，反之對於節能設計較差的建築物，基準及格門檻將適度提升，亦即對於建築節能成效自動產生「優者更優，劣者更劣」的加乘效果。日後本動態基準如獲建築節能法令研修時採納，相信必能增進大型空間類建築物之節能設計成效。

The Huge Space Buildings were involved in Building Energy Conservation Code for 3 years. But the code standard was designed as several different grades. It leaded to a lot of contention cause of its unfair standard system recently. This paper intends to establish a multi-regression dynamic standard to solve the question above-mentioned. On the basis of not increasing calculating work, the regression formulas provide more reasonable and sensible dynamic standard. Regarding the accuracy analysis, the lowest R2 value of the 6 regression formula is as high as 0.94. Furthermore, the dynamic standard overestimated the AWSG values of the huge space buildings which have better solar radiation blocking design in facades; while underestimates on the contrary it is. That means the dynamic standard benefits the buildings which have better energy-saving elevation design. if the dynamic standard is adopted by the code establishing authority concerned, the effect on building energy conservation will be surely enhanced.
