Most studies linking indoor environments and productivity have been conducted in controlled, static conditions often unrepresentative of the real world. This paper uses a case-study-based, real-world approach to empirically investigate the link between indoor environment and workplace productivity in a mechanically-ventilated office environment in southern England. Environmental parameters were monitored continuously. Transverse and longitudinal surveys recorded perceptions of the working environment and self-reported productivity. Performance tasks provided proxy measures of performance. Productivity was perceived to decrease when occupants perceived thermal discomfort and stuffy air. Correlations with perceived changes in productivity were stronger for perceived rather than measured environmental conditions, implying occupants’ subjective feelings impacted perceived productivity more than objective environmental conditions. Task scores were 15% lower when conducted at CO2 levels above 800 ppm compared to below 800 ppm. Insights from the study can help to optimize indoor office environments and improve workplace productivity.

在现代英国办公楼中定义室内环境和工作场所生产力之间的联系

大多数将室内环境和生产力联系起来的研究都是在受控的、静态的条件下进行的，这些条件通常不能代表现实世界。本文使用基于案例研究的真实世界方法，对英格兰南部机械通风办公环境中室内环境与工作场所生产力之间的联系进行实证研究。连续监测环境参数。横向和纵向调查记录了对工作环境和自我报告生产力的看法。性能任务提供了性能的代理度量。当居住者感觉到热不适和闷热时，生产力就会下降。感知到的环境条件与感知到的生产力变化的相关性更强，而不是测量的环境条件，暗示居住者的主观感受比客观环境条件更能影响感知生产力。与低于 800 ppm 的 CO2 水平相比，在高于 800 ppm 的 CO2 水平下进行任务分数降低 15%。该研究的见解有助于优化室内办公环境并提高工作场所的生产力。
