将㶲概念应用于建筑环境研究是一种相对较新的方法。它有助于优化气候调节系统，使其满足可持续建筑设计的要求。由于建筑物应为其居住者提供健康舒适的环境，因此合理地考虑建筑物内的火用流和人体内的火用流。到目前为止，还没有关于人体火用消耗率与主观评估的热感觉之间关系的数据。目前工作的目的是将早期热舒适研究的热感觉数据与计算的人体火用消耗率联系起来。结果表明，人体最小火用消耗率与接近热中性的热感觉投票相关，倾向于热感觉稍冷的一侧。一般来说，气温与火用消耗率之间的关系，作为一级近似值，呈现出增加的趋势。通过使用计算的工作温度来考虑人体与周围环境之间的对流和辐射热交换，当工作温度升高到24°C以上或降低到22°C以下时，火用消耗率会增加。利用目前可用的数据，建立了热感觉与火用消耗率之间的二阶多项式关系。
Application of the exergy concept to research on the built environment is a relatively new approach. It helps to optimize climate conditioning systems so that they meet the requirements of sustainable building design. As the building should provide a healthy and comfortable environment for its occupants, it is reasonable to consider both the exergy flows in building and those within the human body. Until now, no data have been available on the relation between human-body exergy consumption rates and subjectively assessed thermal sensation. The objective of the present work was to relate thermal sensation data, from earlier thermal comfort studies, to calculated human-body exergy consumption rates. The results show that the minimum human body exergy consumption rate is associated with thermal sensation votes close to thermal neutrality, tending to the slightly cool side of thermal sensation. Generally, the relationship between air temperature and the exergy consumption rate, as a first approximation, shows an increasing trend. Taking account of both convective and radiative heat exchange between the human body and the surrounding environment by using the calculated operative temperature, exergy consumption rates increase as the operative temperature increases above 24°C or decreases below 22°C. With the data available so far, a second-order polynomial relationship between thermal sensation and the exergy consumption rate was established.
