ABSTRACT

This study examines the perceived productivity of office occupants in moderate thermal environments in Chile. Specifically, it analyses environmental parameters and contrasts participants’ self-reported answers to cross-sectional and retrospective questionnaires. To this end, data were collected for one day in winter and one day in summer, in eighteen office buildings in the cities of Concepción and Santiago. The results show that the average operative temperatures are 22.2 °C in winter and 23.5 °C in summer. 80.5% of the occupants declared their productivity to be normal on the cross-sectional survey. However, on the retrospective survey, 82.7% said that their productivity is affected by the thermal environment. To reveal the interrelationships between perceived productivity and the thermal environment, a categorical principal components analysis was carried out. It demonstrated that there is only a relationship between cross-sectional and retrospective productivity in winter. Subsequently, a good-fitting structural equation model was created, which showed that different relationships exist between the variables. These findings could enable organizations and design professionals to better understand occupants’ perceived productivity in relation to thermal conditions in office buildings.

摘要

本研究调查了智利中等热环境中办公室人员的感知生产力。具体来说，它分析环境参数并对比参与者对横断面和回顾性问卷的自我报告答案。为此，在康塞普西翁市和圣地亚哥市的 18 座办公楼中收集了冬季一天和夏季一天的数据。结果表明，冬季平均工作温度为22.2°C，夏季为23.5°C。80.5%的住户在横断面调查中表示他们的生产力正常。然而，在回顾性调查中，82.7% 的人表示他们的生产力受到热环境的影响。为了揭示感知生产力和热环境之间的相互关系，进行了分类主成分分析。它表明冬季的横截面生产力和追溯生产力之间仅存在关系。随后，建立了一个拟合良好的结构方程模型，表明变量之间存在不同的关系。这些发现可以使组织和设计专业人士更好地了解居住者在办公楼中与热条件相关的感知生产力。
