本研究建议在热舒适性研究中应用“首选温度”而不是中性温度，特别是在寻找舒适温度范围时。目前，在热舒适性研究中，中性温度被认为是人体的舒适温度。本研究对这一观点提出了质疑，并对中性温度在热舒适研究中的使用、标准舒适区和热舒适标准提出了质疑。在日本、挪威和英国三个不同的工作环境中，对大约5,000名受访者进行了热舒适性的现场测试研究。热感觉，偏好和环境测量收集和分析使用格里菲斯方法。在这三种情况下比较了首选和中性温度，并观察到差异。总的来说，这项研究表明，热偏好（TP）更有可能是一个更准确的措施，在评估热舒适性，特别是它在真实的世界的背景下（例如，改变室温）的直接影响更有可能导致居住者舒适。这表明中性的热感觉并不能保证乘员的热舒适度，因为乘员可能想要中性以外的其他感觉（例如，乘员尽管感觉中性，但仍然更喜欢改变）。重要的是要认识到，非中性的热感觉被认为是热舒适的一些居住者，并包括在未来的研究，以及在设置室温和建筑物的能源性能的直接影响。
This study recommends the application of “preferred temperature” rather than neutral temperature in thermal comfort studies, particularly when focused on finding the range of comfort temperatures. Currently, neutral temperature is considered as comfort temperature of the occupants in thermal comfort research. This study challenged this view and questioned the use of neutral temperature in thermal comfort studies, standard comfort zone and thermal comfort standards. Field test studies of thermal comfort were carried out on about 5,000 respondents in three distinct workplace contexts: Japan, Norway and the UK. Thermal sensation, preference and environmental measurements were collected and analysed using the Griffiths method. Preferred and neutral temperatures were compared in these three contexts and differences were observed. Overall, this study suggests that thermal preference (TP) is more likely to be a more accurate measure in assessing thermal comfort and particularly the direct implication of it in the real world context (e.g. changing the room temperature) is more likely to result in occupant comfort. It suggests that a neutral thermal sensation does not guarantee thermal comfort of the occupant, as the occupant may want other sensations than neutral (e.g. the occupant still prefers a change although feeling neutral). It is essential to recognise that non-neutral thermal sensations are considered as thermal comfort for some occupants and to include this in future research as well as the direct implication in setting the room temperature and the energy performance of the building.
