摘　　要：研究围护结构采暖负荷随外墙及外窗传热系数和窗墙比的变化关系;根据现行标准,给出不同室外温度下,该地区单位面积围护结构采暖负荷限值;为了满足采暖负荷限值要求,围护结构总传热值应当不大于1.427W/(m2.K),当外窗传热系数降低到一定数值时,外墙可不采取保温措施。本文从采暖能耗角度为长江流域围护结构保温设计提供理论依据。Firstly, it was investigated the relationship between the heating load of the building envelop and heat transfer coefficients of the wall and the window, area ratio of window to wall; then it gives limiting value for the heating load of the building envelops at different outside air temperatures according to the current design standard. In order to meet the requirements of the limiting heating load, the overall thermal transfer value should not excess 1. 427W/（ m^2 · K）, and no insulation measures are needed when the heat transfer coefficient decreases to a certain value. This paper will provide a theoretical foundation for the insulation design of the building envelop in the Yangtze Valley from the point of view of energy consumption for heating.
