The research on natural energy utilization using the characteristic of the exterior thermal insulation

利用窗规格和标准气象资料计算了不同类型窗的热平衡，得出内侧采用低辐射率玻璃的三层窗是寒冷地区住宅的最佳选择。对确定地热损失最大值和年值的简化计算方法进行了修正和推广。此外，对高窗热对流通风、柴火采暖等被动式技术进行了量化，提出了实用的设计方法。

Heat balance of various types of window was calculated by utilizing window specifications and standard meteorological data, and thus triple-layered window which has low emissivity glass in the interior side is concluded as the bestoption for houses in a cold region. A simplified calculation method for the determination of the maximum and annual values of ground heat loss was revised and extended. In addition, the quantification of passive techniques such as thermal convectionventilation of the high window and firewood space heating was done, and the practical design method was developed.
