ABSTRACT

Controlled non-uniform indoor thermal environments have the potential to evoke thermal pleasure in occupants as explained by the psychophysiological framework of alliesthesia. In this study, the authors aimed to explore thermal pleasure inside solar screen shaded, single-occupancy, perimeter office set-ups that are within a 4.5 m distance from a building facade. Two solar screens, static (stationary) and dynamic (movable), were designed to differently control the thermal environments inside the single-occupancy, perimeter office set-ups. A within-subject experiment was designed in which 27 human participants were exposed to both set-ups. Subjective responses on thermal pleasure as well as objective data including the participants’ physiological responses and indoor environmental data were collected during these exposures. Correlations between the subjective responses and objective data were analysed. Ramps in operative temperatures and skin temperature contrasts were found to have a significant influence (p < 0.05) on evoking thermal pleasure in ambient thermal environments of the solar-screened, perimeter offices that remained in the upper fringes of the thermoneutrality limits. The findings provide experimental evidence that expands the application of the thermal alliesthesia framework to building perimeter offices. This work contributes to occupant-centric building research by describing an approach to design shading systems that cater to occupant’s thermal pleasure.

摘要

正如同感的心理生理学框架所解释的那样，受控的非均匀室内热环境有可能唤起居住者的热愉悦感。在这项研究中，作者旨在探索距离建筑立面 4.5 m 范围内的太阳能屏遮蔽、单人居住、周边办公室设置内的热乐趣。两个太阳能屏幕，静态（固定）和动态（可移动），旨在以不同的方式控制单人居住的周边办公室设置内的热环境。设计了一项受试者内实验，其中 27 名人类参与者暴露于两种设置。在这些暴露期间收集了对热快感的主观反应以及包括参与者生理反应和室内环境数据在内的客观数据。分析了主观反应和客观数据之间的相关性。发现操作温度和皮肤温度对比的斜坡具有显着影响（p  < 0.05) 在保持在热中性极限的上边缘的有太阳能屏蔽的周边办公室的环境热环境中唤起热愉悦。研究结果提供了实验证据，可将热联觉框架的应用扩展到建筑周边办公室。这项工作通过描述一种设计满足居住者热愉悦感的遮阳系统的方法，为以居住者为中心的建筑研究做出了贡献。
