Abstract Thermal environment is one of the main factors that influence occupants' comfort and their productivity in office buildings. There is ample research that outlines this relationship between thermal comfort and occupant productivity. However, there is a lack of literature that presents mathematical relationship between them. This paper presents a research experimental study that investigates effects of indoor environmental quality factors on thermal comfort and occupant productivity. This study was conducted by collecting indoor environmental quality parameters using sensors and online survey for twelve months. Data analysis was done using Response Surface Analysis to outline any mathematical relationship between indoor environmental quality and occupant productivity. The outlined relationships confirmed dependencies of occupant thermal comfort and productivity on various indoor environmental factors. These dependencies include the effect of CO2 concentration, VOC concentration. These relationships were analysed to rank nine indoor environmental parameters as per the degree of effect on occupant thermal comfort and productivity. These findings would help design professionals to design better office design that would improve occupants’ comfort and their productivity. Study results have different implications for professionals working in design, construction and operation of office buildings. It is recommended that design guidelines for office buildings should consider occupant productivity and incorporate recommended range for indoor environmental quality parameters in respective categories and criteria.

写字楼热舒适度对居住者生产力的影响：响应面分析

摘要 热环境是影响办公楼居住者舒适度和工作效率的主要因素之一。有大量研究概述了热舒适性和居住者生产力之间的这种关系。然而，缺乏文献表明它们之间的数学关系。本文提出了一项研究实验研究，研究室内环境质量因素对热舒适性和居住者生产力的影响。这项研究是通过使用传感器和在线调查收集室内环境质量参数进行的，为期 12 个月。数据分析是使用响应面分析完成的，以概述室内环境质量和居住者生产力之间的任何数学关系。概述的关系证实了居住者热舒适度和生产力对各种室内环境因素的依赖性。这些相关性包括 CO2 浓度、VOC 浓度的影响。根据对居住者热舒适度和生产力的影响程度，对这些关系进行分析，以对九个室内环境参数进行排名。这些发现将帮助设计专业人士设计出更好的办公室设计，从而提高居住者的舒适度和生产力。研究结果对从事办公楼设计、建造和运营的专业人士有不同的影响。建议办公楼的设计指南应考虑居住者的生产力，并将室内环境质量参数的推荐范围纳入各自的类别和标准。
