Abstract Indoor environmental quality (IEQ) has an influence on peoples' health, cognitive performance and productivity in school and office environments. This study used environmental temperature, humidity, air pressure, and CO2 sensor data collected during 3.5–7 months in an office and a school facility to classify occupants’ perceptions of IEQ, stress and productivity in two classes, “negative” and “positive”. Self-reported data from 15 office workers and four teachers were used to train person-specific SVM classifier models. Relatively high accuracies were achieved in classifying IEQ (84%), stress (88%) and productivity (92%) using different combinations of environmental sensor data. Furthermore, the associations between the Big Five personality trait variables (neuroticism, extraversion, openness, agreeableness and conscientiousness) and negative experiences regarding stress, productivity and IEQ were investigated. Positive correlation was found between extroversion and co-occurring stress and IEQ problems, which suggest that more extroverted people more likely to be stressed by insufficient environmental quality or to be more sensitive to environmental factors when under stress. Overall, the results indicate that it is possible to measure and classify perceived IEQ, stress and productivity sufficiently accurately using inexpensive environmental sensors.

基于环境传感器数据和个性分类的感知室内环境质量、压力和生产力评估

摘要 室内环境质量（IEQ）对人们在学校和办公环境中的健康、认知表现和生产力有影响。本研究使用在办公室和学校设施中 3.5-7 个月收集的环境温度、湿度、气压和 CO2 传感器数据，将居住者对 IEQ、压力和生产力的感知分为“负面”和“正面”两类. 来自 15 名上班族和 4 名教师的自我报告数据用于训练特定于个人的 SVM 分类器模型。使用环境传感器数据的不同组合，在对 IEQ (84%)、压力 (88%) 和生产力 (92%) 进行分类时获得了相对较高的准确度。此外，大五人格特质变量（神经质、外向性、开放性、宜人性和尽责性）以及有关压力、生产力和 IEQ 的负面体验。外向性和共生压力与 IEQ 问题之间存在正相关，这表明越外向的人越容易因环境质量不足而感到压力，或者在压力下对环境因素更敏感。总的来说，结果表明，可以使用廉价的环境传感器足够准确地测量和分类感知的 IEQ、压力和生产力。这表明，外向的人更容易受到环境质量不足的压力，或者在压力下对环境因素更加敏感。总的来说，结果表明，可以使用廉价的环境传感器足够准确地测量和分类感知的 IEQ、压力和生产力。这表明，外向的人更容易受到环境质量不足的压力，或者在压力下对环境因素更加敏感。总的来说，结果表明，可以使用廉价的环境传感器足够准确地测量和分类感知的 IEQ、压力和生产力。
