地下工程办公空间中照度和色温对主观评价和工作效率的影响的初步探究

Exploring the Effects of Illuminance and CCT on Self-reported Satisfactions and Working Performances in Underground Working Space:a Pilot Investigation in an Office Without Daylight

本研究以地下工程办公空间为研究对象,通过模拟类似地下工程空间的无天然光环境,以色温、照度两个参数为实验变量,模拟地下工程办公空间日常工作状态,通过评估视觉与非视觉主观反馈及工作效率,探讨照度、色温对人的视觉、非视觉及工作效率的影响。结果表明:高照度(1000 lx)条件下的视觉主观评价和觉醒度反馈相比低照度(150 lx)更受被试偏好;情绪和工作效率在本实验中并未受到照度色温变量的显著影响;照度相比色温对视觉主观评价的影响更明显。

This article presents a pilot study of effects of illuminance and CCT on occupants’visual performance,alertness,mood,and working performance in underground engineering office space.The laboratory was illuminated by adjustable artificial lights,while no daylight was allowed,thus simulating the real lighting environment of underground working space.Key findings are as follows:Higher illuminance(1000 lx)received better subjective visual performance and alertness feedback compared with low illuminance(150 lx);Mood and work efficiency were not significantly affected by illuminance and CCT in this experiment;Illuminance has more obvious influence on visual subjective evaluation compared with CCT.
