虽然室内环境质量（IEQ）因素在环境中共存，这些因素的相互作用及其对认知功能和感知舒适度的影响尚未得到全面的研究。在这项研究中，温度，照明相关色温（CCT）和噪声水平之间的相互作用对选择性注意力，持续注意力，创造力，声学，热，视觉和整体IEQ舒适的年轻人在北美地中海气候的开放式办公室。在一个混合设计的控制实验环境中，招募了52名年轻人，并通过统计分析来评估他们的客观认知表现和主观舒适度。实验设定点分别包括[20 °C，25 °C]，[2700 K，6500 K]和[50 dB，65 dB]的温度，照明颜色和噪音。此外，这项工作还考虑了参与者的性别和体重指数（BMI）。结果表明，温度调节噪声水平和照明CCT对选择性注意的影响，IEQ对持续性注意的影响不显著;创造力受性别及其与噪声水平的交互作用的影响。在感知舒适度方面，声学舒适度随温度变化显著。热舒适性受照明CCT和BMI对温度的联合调节作用的影响，而视觉舒适性受性别对照明CCT的调节作用的影响。整体舒适度受到噪音水平和温度的影响。最后，认知性能指标与感知IEQ舒适投票相关。根据这项研究的结果，考虑噪音，照明CCT，温度，性别和BMI之间的相互作用可以塑造以居住者为中心的优先事项，以增强认知功能和舒适度。
While Indoor Environmental Quality (IEQ) factors in an environment co-exist, the interaction effects of these factors and their impacts on cognitive functioning and perceived comfort have not been comprehensively examined. In this study, the interaction effects between temperature, lighting Correlated Color Temperature (CCT), and noise levels on selective attention, sustained attention, creativity, acoustics, thermal, visual, and overall IEQ comfort of young adults in open-plan offices in North American Mediterranean climate were presented. In a mixed-design controlled experimental setting, 52 young adults were recruited, and their objective cognitive performance and subjective comfort were assessed through statistical analysis. The experimental set points included [20 °C, 25 °C], [2700 K, 6500 K], and [50 dB, 65 dB] for temperature, lighting color, and noise, respectively. Additionally, the work took into consideration the gender and Body Mass Index (BMI) of participants. The results show that temperature moderated the effect of noise level and lighting CCT on selective attention, while no effect of IEQ factors on sustained attention was found. Creativity was influenced by gender and its interaction with the noise level. Concerning perceived comfort, acoustic comfort varied significantly with temperature. Thermal comfort was influenced by the combined moderating effect of lighting CCT and BMI on temperature, while visual comfort was driven by the moderation effect of gender on lighting CCT. Overall comfort was affected by the noise level and temperature. Finally, cognitive performance indicators were correlated with perceived IEQ comfort votes. Based on the findings of this study, considerations of interactions between noise, lighting CCT, temperature, gender, and BMI can shape occupant-centric priorities for enhanced cognitive functioning and comfort.
