Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application.

Among the indices for evaluating heat transfer performance of windows, solar heat gain coefficient (Solar Heat Gain Coefficient, SHGC) and U-value heat transfer coefficient are two commonly used thermal performance indices.
Solar heat gain coefficient, also known as total solar transmittance (abbreviated as SHGC value), is the ratio of the amount of solar radiant heat that is taken indoors through glass, door, window, or curtain wall members to the amount of solar radiant heat that is projected onto the glass, door, or curtain wall members. At present, the construction energy consumption analysis is generally carried out by adopting an SHGC value in China, and the Sc value of an external window is replaced by the SHGC value in GB50189 public construction energy conservation design Standard of China 2015.
U value heat transfer coefficient, defined as the amount of air-to-air heat transfer due to glass heat transfer and indoor and outdoor temperature differentials under ASHRAE standard conditions. The U value can reflect the conduction and convection when the temperature difference exists between the indoor and the outdoor, and the conduction and convection when the temperature difference exists between the indoor and the outdoor can be reflected by the U value, wherein the conduction and convection when the glass absorbs heat energy and then radiates energy which is transmitted into the indoor in a convection and radiation mode. The English system unit is as follows: BTU/(h·ft) per unit of heat per hour per square foot per temperature fahrenheit 2 F.; the metric units are as follows: w/(m) per square meter per Kelvin temperature 2 · ° C)。
The SHGC values and U values used in the methods provided herein can be obtained by actual project table lookup, such as table 1-U value heat transfer coefficient table, and such as table 2-solar heat transfer coefficient table.
