既有工业建筑围护结构热工性能参数特征分析
Thermal performance parameter characteristics of existing industrial building envelopes
摘要：
通过对既有工业建筑的调研，分析了工业建筑环境控制方式、体形系数、窗墙面积比、围护结构热工性能参数等的特征。结果表明：工业建筑体形系数变化范围比民用建筑小，其中近90%的工业建筑体形系数在0.15以下；工业建筑窗墙面积比变化范围比公共建筑小，与居住建筑较为类似；一类工业建筑的围护结构热工性能要求在严寒和寒冷地区比民用建筑低，但在夏热冬冷和夏热冬暖地区比居住建筑稍高。
Abstract：
Through the investigation of existing industrial buildings, analyses the characteristics of industrial building environmental control, shape coefficient, window-to-wall ratio and thermal performance of envelopes. The results show that the variation range of shape coefficient of industrial buildings is smaller than that of civil buildings, with a shape coefficient of less than 0.15 in almost 90% of industrial buildings. The variation range of window-to-wall ratio of industrial buildings is smaller than that of public buildings, and similar to residential buildings. The envelope thermal performance requirements of first category industrial buildings are lower than those of civil buildings in severe cold zone and cold zone, but slightly higher than those of residential buildings in hot summer and cold winter zone and hot summer and warm winter zone.
