建立了一个方程来预测建筑物中自然和机械引起的气流的综合影响，并通过分析和迭代方法相结合来求解。由此产生的二维公式，作为一个简单的计算机程序实现，可以快速、每小时模拟具有一系列通风策略的家庭规模建筑的渗透。该实施用于比较三种通风策略（自然通风、机械抽气和平衡的全屋机械通风）的能源使用和二氧化碳排放量，作为住宅气密性的函数。这项练习证实了如果要最大限度地发挥平衡机械通风与热回收的优势，就需要气密性。
An equation is developed for predicting the combined effect of naturally and mechanically induced air flows in buildings and solved by a combination of analytical and iterative methods. The resulting two-dimensional formulation, implemented as a simple computer program, allows rapid, hourly simulation of infiltration in domestic-scale buildings with a range of ventilation strategies. This implementation is used to compare energy use and carbon dioxide emissions for three ventilation strategies—natural ventilation, mechanical extract and balanced, whole-house mechanical ventilation— as a function of dwelling airtightness. This exercise confirms the need for airtightness if the benefits from balanced mechanical ventilation with heat recovery are to be maximised.
