Analysis of Shading Parameter Values for Low-E Glass Windows in Building Energy Efficiency Design
Energy saving exterior windows belong to precision industrial products and are also an important component of the exterior envelope structure of building engineering.In order to reduce the summer solar heat gain in the room,low radiation Low-E glass exterior windows are usually used in engineering.However,due to the varying parameter values of Low-E glass windows in national and regional technical specifications,the grasp scale of drawing review agencies,and the varying processing technology levels of door and window manufacturers,in order to solve the problem of difficult shading parameter values and selection of Low-E glass exterior windows,and achieve clear concepts,reliable data For the purpose of facilitating implementation,the article uses formula calculation and table comparison methods to supple-ment the concept of standard shading parameters.At the same time,combined with the engineering prac-tice of a residential project in Jiangsu,the principles and suggestions for selecting the shading parameters of Low-E glass windows are given.It is believed that the maximum self shading coefficient of Low-E glass should not exceed 0.60.
