研究居住者行为的主要目的是提高建筑物的能源性能。然而，如果不了解居住者、他们的需求和偏好，就很难减少能源使用。个体差异和偏好的热环境与空间背景的关系被忽视的主流研究。本研究旨在探讨使用者在感知热环境时，基于个人差异的热偏好模式，以提升使用者的舒适度与能源效能。采用了一种新的视觉热景观方法，这是一种定性的方法来分析居住者的舒适性和用户的行为，根据空间背景。这种方法摆脱了“热中性”和通用结果的概念，而是通过基于个体差异和空间背景信息的个人舒适度的定性分析，向细节和意义开放。在英国、瑞典和日本的5座办公楼中进行了热舒适性的现场测试研究，共收集了2313个数据集。该研究的主要贡献是确认了四种热偏好模式，包括一致的方向偏好;波动的偏好;高耐受性和对热变化敏感;以及高耐受性和对热变化不敏感。在纵向热舒适性现场测试研究中进一步检验了结果。在几种情况下，当窗户固定时，观察到居住者的热舒适性和偏好受到室外条件影响的影响。推荐了研究、实践和建筑设计的实用解决方案，对居住者舒适度和能源使用有直接影响。
The main purpose of research on occupant behaviour is to enhance building energy performance. However, it is difficult to reduce the energy use without understanding the occupant, their needs and preferences. Individual differences and preferences for the thermal environment in relation to the spatial context are overlooked in the main stream of research. This study investigates the patterns of occupant thermal preference based on individual differences in perceiving the thermal environment to enhance user comfort and energy performance. A novel method of Visual Thermal Landscaping is used, which is a qualitative method to analyse occupant comfort and user behaviour according to the spatial context. This method drives away from the notion of ‘thermal neutrality’ and generic results, rather it opens to details and meaning through a qualitative analysis of personal-comfort, based on individual differences and spatial context information. Field test studies of thermal comfort were applied in five office buildings in the UK, Sweden and Japan with overall 2313 data sets. The primary contribution of the study was the recognition of four patterns of thermal preference, including consistent directional preference; fluctuating preference; high tolerance and sensitive to thermal changes; and high tolerance and not-sensitive to thermal changes. The results were further examined in a longitudinal field test study of thermal comfort. In several cases, occupant thermal comfort and preferences were observed to be influenced by the impact of outdoor conditions, when the windows were fixed. Practical solutions for research, practice and building design were recommended with direct implications on occupant comfort and energy use.
