Underground spaces have received increasing attention in the past decades owing to the growing urban land scarcity. Underground spaces can have a variety of functions such as storage, shelter, and civic infrastructures, while underground buildings for human activities have gained less attention mostly due to the challenges in creating suitable living and working environments. With the attempt to design a healthy, comfortable and energy efficient underground building, this paper conducts a comprehensive review on the studies related to energy, thermal comfort and indoor air quality performances of underground buildings, ranging from prediction methods to influential factors to improving solutions. The review reveals that numerical simulation is mostly used to study underground building energy performance while field experimentation is primarily employed for investigating underground building indoor environment quality performance. Finite difference method is found to be the most adopted numerical method to predict the energy performance of underground buildings. Inherent uncertainty issues in ground coupled heat transfer still need to be improved to reflect more physics and balance prediction accuracy with computational cost. Further research is more necessary and crucial in the field of indoor environment quality performance than energy efficiency performance for underground buildings.

地下建筑的研究进展:能源,热舒适性和室内空气质量

由于城市土地稀缺的日益增加,地下空间在过去几十年中受到越来越多的关注。地下空间可以具有多种功能,例如存储,住房和市政基础设施,而用于人类活动的地下建筑受到的关注较少,这主要是由于创造合适的生活和工作环境所面临的挑战。为了设计一种健康,舒适和节能的地下建筑,本文对地下建筑的能量,热舒适性和室内空气质量性能进行了研究,涵盖了预测方法,影响因素以及改进解决方案等方面。审查表明,数值模拟主要用于研究地下建筑的能源性能,而现场试验则主要用于调查地下建筑的室内环境质量性能。发现有限差分法是预测地下建筑物能源性能的最常用的数值方法。地面耦合传热中固有的不确定性问题仍需要改进,以反映更多的物理特性,并使预测精度与计算成本保持平衡。在室内环境质量性能方面,比地下建筑物的能效性能更进一步的研究是必要和关键的。发现有限差分法是预测地下建筑物能源性能的最常用的数值方法。地面耦合传热中固有的不确定性问题仍需要改进,以反映更多的物理特性,并使预测精度与计算成本保持平衡。在室内环境质量性能方面,比地下建筑物的能效性能更进一步的研究是必要和关键的。发现有限差分法是预测地下建筑物能源性能的最常用的数值方法。地面耦合传热中固有的不确定性问题仍需要改进,以反映更多的物理特性,并使预测精度与计算成本保持平衡。在室内环境质量性能方面,比地下建筑物的能效性能更进一步的研究是必要和关键的。
