减少建筑物的外露面积是建筑节能的必要条件,但不是唯一条件。建筑物的节能与否,不只是与建筑物的外露面积有关,还同时与围护结构的热工性能以及建筑内部的各种负荷有关。 所谓建筑体形系数(F/V)——建筑物的外露面积与其所包围的建筑体积之比——只能反
Reducing the exposed area of a building is a necessary condition for building energy conservation, but it is not the only condition. Whether or not a building is energy-efficient is not only related to the exposed area of the building, but also related to the thermal performance of the envelope and the various loads inside the building. The so-called architectural shape factor (F/V)—the ratio of the exposed area of a building to the volume of the building it surrounds—can only be reversed.
