摘要
分析典型围护结构在夏热冬冷地区9个主要城市中应用的全年热工性能,即夏季制冷和冬季采暖时的能耗。比较几种节能措施的效果。加强墙体保温虽然有效,但不如加强玻璃窗的保温效果好;遮阳措施的节能效果很明显;但采暖季太阳辐照足够强时,可考虑提高围护结构的透射率。与单层幕墙或传统的墙+窗的围护结构相比,双层玻璃幕墙具有较好的保温性能和方便的遮阳设置,能适应冬夏季节的不同需求,因此在夏热冬冷地区有较好的节能潜力。
The paper analyses the net annual energy flow （heating and cooling seasons） through typical types of envelopes in nine major cities in the hot summer and cold winter zone of China. The results show that the window insulation is more effective than wall insulation and the shading is critical to energy efficiency during the cooling season. When solar radiation is strong enough in the heating season, building design should consider making the facade more transparent to the solar radiation. Compared with the single skin facade and the traditional wall-window envelope, the double skin facade has overall advantages in this region by being transparent, insulated, and at the same time able to provide better shading schemes. Therefore, the double skin facade is potentially a suitable and energy efficient envelope in the hot summer cold winter zone of China.
