Measurement and Analysis of Indoor Thermal Environment of Regeneration Space of School-Run Factory in Winter: A Case Study on the Architectural Design Studio in NO.246 Guang Yan Road in Shanghai

摘要: 校办工厂出现于我国特殊发展阶段,现面临改造与再利用。建筑物理环境是这类改造项目的重要评价维度。以热环境为切入点,在校办工厂再生空间中布点实测,分析其冬季热环境状况,揭示其影响要素及作用机制。试验结果表明:1)在冬季非极端气候条件下,室内空气温度为7.0~10.0℃,相对湿度为40.0%~60.0%,室内空间热量分层现象不明显,空气温度低是冬季人体感觉寒冷的主要原因;2)经适度改造的围护结构满足空间使用和特色彰显的需求,但对室内热环境的调控作用有限,与室外温湿波动具有0.5~1.0 h的时滞;3)门斗空间可以有效缓冲室外温湿波动的影响,减少冬季热量流失。从环境结果评价校办工厂改造,可为类似既有建筑改造设计提供新的思考维度。Abstract: School-run factories appear at a special stage of development in our country and are facing transformation. The physical environment is an important dimension for evaluating the transformation of existing buildings. Taking the thermal environment as the starting point, field surveys were conducted on the regeneration space of the school-run factory. The indoor thermal environment in winter was objectively presented, and its influencing factors and mechanism were revealed preliminarily. The experimental results showed that:1) under non-extreme climatic conditions in winter, the indoor air temperature was 7.0-10.0℃, the relative humidity was 40.0%-60.0%, and there was no obvious heat stratification in indoor space, and feeling cold was mainly due to low air temperature; 2) the moderately renovated envelope structure met the needs of space use and distinctive features, but had a limited role in regulating the indoor thermal environment, and there was a 0.5-1.0 h lag time for outdoor temperature and humidity fluctuations; 3) the foyer space effectively buffered outdoor temperature and humidity fluctuations and reduced heat loss in winter. Evaluation of the school-run factory renovation from environmental results could provide new thinking dimensions for the renovation design of similar existing buildings.
