Personal thermal management (PTM) technologies, which establish local thermal envelope around human body instead of cooling/heating the entire building space, have great potential for reducing building energy use and satisfying individual's thermal comfort. Traditional PTM technologies include off-body near-range energy transfer systems and on-body wearable devices. Recently, owing to the progress in nanotechnologies and material sciences, novel fibers and textiles with desirable properties (radiation, thermal, wettability, etc.) have been extensively explored. Classifying and analyzing diverse PTM technologies, this work provides an overview on the human body thermoregulatory system, advantages and disadvantages of various technologies, and more importantly, the evaluation criteria of different technologies in terms of their energy saving and thermal comfort improving performances. Currently, PTM technologies have the potential to achieve 15–30% energy saving in buildings. However, further investigations on PTM technologies are needed, such as evaluation of thermal comfort for novel wearable textiles, and development of other performance indices for wearable PTM technologies including washability and permeability.

个人热管理 (PTM) 技术在人体周围建立局部热围护结构，而不是冷却/加热整个建筑空间，在减少建筑能源使用和满足个人热舒适度方面具有巨大潜力。传统的 PTM 技术包括离体近程能量传输系统和体上可穿戴设备。最近，由于纳米技术和材料科学的进步，具有理想特性（辐射、热、润湿性等）的新型纤维和纺织品.) 进行了广泛的探索。本工作对多种 PTM 技术进行分类和分析，概述了人体体温调节系统、各种技术的优缺点，更重要的是，提供了不同技术在节能和热舒适性改善性能方面的评估标准。目前，PTM 技术有潜力在建筑物中实现 15-30% 的节能。然而，需要对 PTM 技术进行进一步研究，例如评估新型可穿戴纺织品的热舒适性，以及开发可穿戴 PTM 技术的其他性能指标，包括耐洗性和渗透性。
