摘要
基于建筑中庭顶部采光室内环境以及热舒适度的视角,选取郑州某示范建筑为研究对象,在冬季晴天进行光环境和热环境实测。结果表明,中庭垂直方向出现明显的温度分层,最大温差达7.1℃。首层中庭功能区天然采光性能良好,测试日白天的绝大部分时间均可利用天然光照明。采用预测平均热反应PMV指标进行评价,首层中庭功能区测试时段热舒适性较为适宜。该建筑将中庭北面挑空层与南向采光坡屋面相结合的设计方案具有借鉴意义。
Based on the perspective of indoor environment and thermal comfort of top daylighting atrium building,an atrium of a demonstration building in Zhengzhou was selected as the research object,and the lighting and thermal environment was measured in sunny winter.The results showed that significant temperature stratification appeared in the vertical direction of the atrium,and the maximum temperature difference reached 7.1℃.The daylighting performance of the atrium functional area on the first floor is good,and natural lighting can be used for most of the test day.The predicted average thermal response PMV index is used for evaluation.The thermal comfort of the first floor atrium function area is more suitable during the test period.The building’s design scheme that combines the buffer floor on the north side of the atrium with the south-facing slope skylight is worth learning.
