寒冷，自然对流从玻璃幕墙往往是在冬季的热不适的原因，有必要进行研究，以改善设计方法。研究的目的是发展的地板面积以外的空气流动的表达式，它影响在占用区的热舒适性。推导出了最大速度随离地面距离的减小率和冷气流沿着地板与占用区其余部分之间的最大温差的表达式。由于垂直面的冷下沉气流，对占领区不满意的人的百分比进行了估计。
Cold, natural convective flows from glazed facades are in winter time often the cause of thermal discomfort and there is a need for research to improve design methods. The objective of the research is to develop expressions for the air flow beyond the floor area, which influences the thermal comfort in the occupied zone. Expressions for the rate of decrement of the maximum velocity with distance from the surface and for the maximum temperature difference between the cold air flow along the floor and the rest of the occupied zone have been developed. The percentage of dissatisfied persons in the occupied zone, due to cold downdraught from a vertical surface, has been estimated.
