为什么较低的 SHGC 有时更节能?

每一步 ATO 处理同时实现两个效果:阻隔近红外热量(SHGC 降低 → 制冷负荷减少)并且它会降低可见光透射率(Tvis 越低 → 人工照明需求越高)。

在冬季寒冷的温带气候地区(如伊斯坦布尔、马德里),较低的 SHGC 也意味着冬季获得的免费太阳热量减少,从而增加供暖负荷。最低 kWh 配置取决于制冷节能、供暖成本与照明成本三者的平衡点——通常并非在 SHGC 最低处。

请始终以结果面板中显示的总 kWh 最低值为优化目标,而非最低 SHGC 参数值。如有 Low-e 变体可选,建议添加——其 U 值降幅(>2 倍)通常足以弥补冬季供暖损失。

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.
