This study investigated the lighting factors that influence occupants' thermal perception and physiological thermal responses to propose a lighting design guide that considers thermal comfort in office spaces. Related literature was collected and reviewed regarding experimental results on occupants' thermal comfort under various LED lighting conditions. The analysis identified CCT, illuminance, and monochromatic light as key lighting factors affecting occupants’ thermal comfort. The biomedical signals used to measure the occupants’ thermal comfort include melatonin, cortisol, CBT, SKT, BP, HR, HRV, EE, and EEG and these signals are categorized into groups related to circadian rhythm, thermal response, metabolic rate, and mental workload. Furthermore, optimal settings for CCT were found to be 3700 K at 23°C, 4500 K at 26°C, and 6000 K at 29°C, with illuminance levels ranging from 500 lx to 1000 lx, which were shown to improve both thermal comfort and work efficiency in office spaces. Finally, the Kruithof curve demonstrated that it is not suitable as a lighting design criterion for office spaces using LED lighting, indicating the need for revision or the introduction of new metrics.
