基于ECOTECT模拟的魏家大院冬季热舒适性研究

Research on the thermal comfort in winter of Weijia Courtyard in southern Jiangxi Province based on ECOTECT simulation

为探究并改善传统民居的热舒适性,通过对冬季工况下魏家大院热环境要素实测数据及ECOTECT软件模拟结果进行耦合分析,以探讨赣南传统民居魏家大院建筑群的热舒适性特征。结果表明:针对魏家大院“厅屋组合式”的建筑空间布局,室外及天井处PMV的波动值大于室内,且两种研究方法下天井处测值弹性变化幅度均大于室内,但总体变化趋势相近。最终提出面向冬季工况下热舒适性改善的传统建筑空间优化建议,以期为传统建筑再利用提供新思路。

To explore and improve the thermal comfort of traditional dwellings,the thermal co mfort characteristics of traditional dwellings in southern Jiangxi were discussed by coupling analysis of the measured data of thermal environment elements of Wei’s Courtyard in winter and the simulation results of ECOTECT software.The results show that,according to the spatial layout of“hall and house combination”of Weijia Courtyard,the fluctuation value of PMV in outdoor and patio is larger than that in indoor,and the elasticity variation range of measured value in patio is larger than that in indoor under the two research methods,but the overall trend of change is similar.Finally,the paper puts forward some suggestions on the space optimization of traditional buildings for the improvement of thermal comfort under winter conditions,in order to provide new ideas for the reuse of traditional buildings.
