信息反馈对室内环境主观评价影响的实验研究
|
摘要
基于北京某办公室夏季工况热舒适和光感觉实验,研究了室内环境参数实时反馈对于用户热环境和光环境主观评价的定量化影响。实验设计了3种热环境工况和2种光环境工况,在每种工况稳定后向用户提供包含室内环境参数、标准区间及相应建筑能耗的反馈信息,研究用户主观评价的变化。实验结果显示,用户获得实时室内环境参数后,其对室内热环境和光环境的主观评价产生了显著变化。建筑热环境考虑信息反馈后,能够在一定程度上提升中性、偏热工况下用户的热舒适水平与满意度,热感觉适中的人数分别增加了23.3%和40.0%;对于光环境,信息反馈有利于提高较强光照工况下用户对光环境的满意度评价,非常满意的人数增加了10.0%。基于实验结果,提出了在不同热环境和光环境下,结合实时反馈信息和群体决策,改善室内环境满意度和节能的环境控制策略。
Based on the summer thermal comfort and light sense experiment of an office in Beijing, studies the quantitative influence of real-time feedback of indoor environmental parameters on the occupants' subjective evaluation of thermal and optical environment. Designs three kinds of thermal environment conditions and two kinds of optical environment conditions in the experiment. When each operation condition is stable, provides occupants the feedback information including indoor environmental parameters, standard interval and corresponding building energy consumption, and studies the change of their subjective evaluation. The experimental results show that after the occupants obtain real-time indoor environment parameters, their subjective evaluation of indoor thermal environment and optical environment changes significantly. Considering the information feedback of the building thermal environment can improve the thermal comfort level and satisfaction of occupants to a certain extent, and the proportions of people with moderate thermal feeling under neutral and thermal conditions increase by 23.3% and 40.0%, respectively. For the optical environment, information feedback is beneficial to improve the evaluation of occupants' satisfaction under strong lighting conditions, and the proportion of people who are very satisfied with the optical environment increases by 10.0%. Based on the experimental results, proposes an environmental control strategy to improve indoor environmental satisfaction and energy saving under different thermal and optical environments, combined with real-time feedback information and group decision-making.
