上海创智天地广场热舒适分析与评价

The Analysis and Evaluation of Thermal Comfort at Shanghai Knowledge & Innovation Community Square

主要通过上海创智天地广场夏秋冬三季小气候实测与问卷调查,探讨广场空间形态、热环境和使用者心理感知之间的关系,10个测试日共获得问卷870份。结果表明:1)SVF与广场热环境关系紧密,夏季需要更小的SVF,冬季需要更大的SVF;2)热中性与热舒适范围随季节发生变化,热感觉、热舒适与空气温度、PET显著相关,就相关系数而言,热感觉更高;3)人们的热感觉和热认知较为一致的是广场夏季热环境更为严峻;4)空间开阔是人们在秋冬两季来广场的主要原因,它影响了人们对广场各区的热认知;5)创智广场的热中性范围低于国歌广场,空间形态与行为活动的耦合可能影响了人们的热中性范围。本研究成果可为上海高密度环境广场热环境设计及优化提供依据。

This paper mainly discusses the relationship among space form,thermal environment and users'psychological perception via micro-climatic test and questionnaire in three seasons(summer,autumn and winter)at Shanghai Knowledge&Innovation Community(KIC)Square,with870questionnaires completed during10test days.The analytical results have indicated the following findings.1)The thermal environment of the square closely relates to sky view factors(SVF),and summer requires smaller SVF while winter requires larger SVF.2)The range of thermal neutrality and thermal comfort vary with seasons,both of them are significantly related to air temperature and physiological equivalent temperature(PET),with higher correlation coefficient and thermal sensation.3)Human being's thermal perception and cognition suggests that the thermal environment of the square is in a more severe situation in summer.4)Openness is the main reason for people to come to the square in autumn and winter,which affects people's thermal perception of the square.5)Guoge Square has more broad thermal neutral range than the KIC Square,which may be caused by the coupling effect of square form and behavioral factors.Those findings in this paper may serve as the theoretical foundation for the future design of square of high density in Shanghai.
