Amid recent concern about overheating in Passivhaus, this study investigates geometrical implication of façade design to alleviate overheating in new build energy-efficient homes in the UK. The study proposes self-shading façade design as a less conventional approach to passively protecting the house from the excessive solar gain in summer. The findings show that implementing an optimum angle slanted wall can moderate indoor temperature variations between day and night in summer and could potentially act as an effective shading device. The suggested tilted façade is compared alongside other conventional approaches, such as overhangs and reduced WWR, to compare their relative effectiveness in reducing overheating risk.

建筑形式对过热控制的影响：以落叶松屋为例

在最近对 Passivhaus 过热的担忧中，这项研究调查了立面设计的几何意义，以减轻英国新建节能住宅的过热。该研究提出了自遮阳立面设计作为一种不太传统的方法，可以被动地保护房屋免受夏季过度太阳能的影响。研究结果表明，实施最佳角度的倾斜墙可以缓和夏季白天和黑夜之间的室内温度变化，并有可能作为一种有效的遮阳装置。将建议的倾斜外墙与其他传统方法（例如悬垂和减少 WWR）进行比较，以比较它们在降低过热风险方面的相对有效性。
