為何較低的 SHGC 有時更省能?
每個 ATO 步驟同時發揮兩項作用:阻擋近紅外線熱量(較低 SHGC → 減少冷卻需求)並且它會降低可見光透射率(Tvis 越低 → 人工照明需求越高)。
在冬季寒冷的溫帶氣候地區(伊斯坦堡、馬德里),較低的 SHGC 也意味著冬季可利用的免費太陽熱能減少,從而提高暖氣負荷。最低 kWh 配置取決於冷氣節省、暖氣費用與照明費用三者的平衡點——通常並非在 SHGC 最低時。
請務必以結果面板所示的最低總 kWh 為優化目標,而非最低 SHGC 數值。若有 Low-e 選項,請加入比較——其 U 值降幅(>2 倍)通常足以彌補冬季暖氣損耗。

本結果基於 TNO/BMC 獨立能耗模擬,採用標準化建築模型(1 層、5 間房、全玻璃幕牆,15.2 x 30.5 m)。多層樓結果由已驗證的單層資料線性縮放推算。
實際性能取決於建築朝向、使用模式、HVAC 系統效率及當地氣候條件。所示結果僅供參考,不應取代針對特定建築的能耗評估。
CO₂ 減排量與成本節省依各地電價及電網排放係數計算。幣別換算為近似值。
Simulation methodology
Building model
Energy simulations were independently performed by TNO/BMC (Netherlands Organisation for Applied Scientific Research / Building Model Consultants) using a standardised building model.
- •1 floor, 5 rooms (15.2 × 30.5 m)
- •All-glass facade, 2.4 m height
- •Heating trigger: ≤ 21 °C / Cooling trigger: ≥ 24 °C
- •Glass: laminated DGU (7.26/13/3 mm) and laminated DGU + low-e
Scaling approach
The calculator scales validated single-floor simulation results linearly by the number of floors and glass area. The reference impact model uses an 80-floor building with 37,088 m² total glass area (approximately 463 m² per floor).
Local factors
CO&sub2; reductions are calculated using location-specific grid emission factors. Cost savings use local electricity prices. Both factors are based on data from the original TNO/BMC study and may differ from current market conditions.
