Study On Indoor Environmental Quality Evaluation Model Of Ofifce Building

In order to give more scientific and rational comprehensive evaluation of theindoor environment, indoor environmental assessment of office building was studiedin this paper by using laboratory tests and field investigation, combined withsubjective and objective evaluation methods. The experimental test set of27kinds oftest conditions designed by factorial design theory, did subjective questionnaire andwork efficiency testing on various conditions of30subjects (16males and14females), found the interaction effect of thermal environment, air quality, acousticenvironment, and light environment and comprehensive indoor environmental qualitymodel.Obtained after interaction analysis: No significant interaction effects on thethermal environment effect by air quality and acoustic environment; no effects bylight environment; To the effect of the thermal environment satisfaction, the rise of1℃(<25℃),732ppm lower and13.8dB reduction is roughly equal; the rise of1℃(>25℃),313ppm rise and5.9dB rise is roughly equal. No significant interactioneffect on air quality by the thermal environment and acoustic environment; Lightenvironment had no effect on air quality effects; The rise of13.3℃、100ppm rise and52.4dB rise is roughly equal to the effect of the air quality satisfaction. No significantinteraction effect on acoustic environment by and the thermal environment; Airquality and light environment had no effect on acoustic environment effects; The riseof10.7℃and1dB rise is roughly equal to the effect of the acoustic environmentsatisfaction. No significant interaction effect on light environment by air quality; Thethermal environment and acoustic environment had no effect on light environmenteffects; The lower of363ppm and50lx rise is roughly equal to the effect of the lightenvironment satisfaction.Indoor environmental quality satisfaction and work efficiency model obtainedafter interaction analysis: Thermal environment, air quality, noise environment andlight environment on both a decisive influence; To the effect of Integratedenvironmental satisfaction, the rise of1℃(<25℃),51ppm lower,1.6dB lower and88lx rise is roughly equal; the rise of1℃(>25℃),27ppm rise、0.9dB rise and46lxlower is roughly equal. To the effect of work efficiency, the rise of1℃(<25℃),116ppm lower,17.2dB lower and211lx rise is roughly equal; the rise of1℃(>25℃),61ppm rise、9.6dB rise and111lx lower is roughly equal.
