在确定地面耦合供暖和制冷系统的水平闭合环路和送风涵洞的尺寸时，需要准确估计浅层地面温度。这些集水环路和涵洞位于受季节性温度波动影响的区域内。从106气象局气象站，位于英国各地的土壤温度进行了分析，从平均年，季节性最低和最高，日最低和最高温度已计算。1米深处的年平均温度（折合到海平面）从英格兰南部的12.7°C到苏格兰北方的8.8°C不等，相应的季节温度变化范围分别为10.3°C和7.9°C。在邻近城市绿色空间的地方，在1 m深度处观察到0.55°C的平均城市热岛效应，由此可以假定，在人口密集的城市和城镇中心，城市热岛效应将更大。线性关系已被推导出的平均年温度在任何非城市的英国地方，在1米深。季节性温度循环已被准确地外推到几米深的特定地点的热特性来自土壤温度测量。
Accurate estimations of shallow ground temperatures are required when sizing the horizontal closed loops and air supply culverts of ground coupled heating and cooling systems. These collector loops and culverts are within the zone affected by the seasonal swing in temperatures. Soil temperatures from 106 Met Office weather stations, located across the UK, have been analysed from which mean annual, seasonal minimum and maximum, and daily minimum and maximum temperatures have been calculated. Mean annual temperatures at 1 m depth, reduced to sea level, range from 12.7°C in southern England to 8.8°C in northern Scotland, with corresponding seasonal ranges in temperature of 10.3°C and 7.9°C respectively. An average urban heat island (UHI) effect at 1 m depth of 0.55°C has been observed at localities adjacent to urban green spaces, from which it can be assumed that the UHI effect will be greater in densely developed city and town centres. A linear relation has been derived for the mean annual temperature at any non-urban UK locality, at 1 m depth. The seasonal temperature cycle has been extrapolated accurately to several metres depth with site-specific thermal properties derived from the soil temperature measurements.
