摘　　要：现有的室内物理环境评价教学实验一般只关注声、光、热单一因素影响,缺少对光热复合环境的探究。针对此问题并为消除主观因素对评价指标的影响,该文自制了室内环境仓,通过调节温度、湿度、色温、照度等,模拟不同光热复合环境工况,并利用生理参数和传统指标分别对受试者的舒适度和学习效率进行评价,最后通过对比分析得出最舒适和学习效率最高的光热环境参数指标。实验结果表明,使用生理参数评价指标得到的结果与传统指标得到的结果基本吻合,体现了生理参数指标用于建筑室内环境评价的可行性。该实验使学生了解了人因技术在建筑学中的应用方法,培养了综合性、创新性思维。[Objective]Thermal,light,and sound environment tests and simulation experiments are an important part of the experimental teaching of building physics.However,most current experimental projects are old in content,and the influence of sound and light environment is often ignored in comfort evaluation.Therefore,students’active participation in learning and the overall coordination of indoor comfort experiments are not ideal.To solve the aforementioned problems,this paper uses human factor technology to evaluate the light and thermal environment of the subjects in the learning state from the perspective of learning efficiency and comfort.Through this teaching experiment,students can learn the design and data analysis method of orthogonal experiments and master the basic theoretical knowledge of building thermal optics,the use of relevant experimental instruments,and the measurement method of indoor light and thermal environment parameters.Students are guided to experience different light and thermal environments,and physiological parameters are used to explore their influence on comfort and learning efficiency.Finally,the best light and thermal environment for comfort and learning efficiency is comprehensively proposed.[Methods]In this paper,the evaluation methods of traditional learning performance index and four physiological parameters on learning efficiency,including heart rate variability,brainwaveαrhythm engagement,cognitive engagement,and pupil diameter,were studied.The orthogonal experimental conditions of L9(34)with four factors of temperature,humidity,illumination,and color temperature and three levels were set.The experimental results were analyzed by a range analysis method.An indoor thermal comfort tester and an illuminometer were used to collect light and thermal environment data.Among the four physiological parameters,cognitive engagement was measured by the n-back cognitive task,whereas the others were measured by the human factor data acquisition instrument.After conducting pre-experiment testing
