严寒地区被动式太阳房玻璃窗的节能设计

Study on energy saving design of windows set on passive solar house in chilly area

玻璃窗的节能设计是降低建筑能耗、实现下一步节能目标的重要环节.对玻璃窗和保温墙体的能耗进行了分析计算.针对严寒地区,对不同类型玻璃窗的能耗进行对比,计算出适合不同地区的不同气候条件下的最佳玻璃窗种类、层数.并且引入太阳得热系数来综合评价窗户热工性能,充分利用太阳能,来减少严寒地区采暖能耗.

This paper analyzes energy consumption of glazing and heat preservation wall. It contrasts the energy consumption among different types of glass windows in chilly areas. Based on the analysis, it got the best glass windows types and the best suitable glass layers for different region and different climate. And also introduces the rate of solar energy gained to assess the thermal performance of glass windows. The solar energy can be made use of successfully, and reduce the building energy consumption for heating in chilly area.
