The shading coefficient (SC) is a measure of the radiative thermal performance of a glass unit (panel or window) in a building.It is defined as the ratio of solar radiation at a given wavelength and angle of incidence passing through a glass unit to the radiation that would pass through a reference window of frameless 3 millimetres (0.12 in) Clear Float Glass. [3]
Shading coefficient (SC) is a measure of thermal performance of a glass unit (panel or window) in a building. It is the ratio of solar gain (due to direct sunlight) passing through a glass unit to the solar energy which passes through 3mm Clear Float Glass. [ 1 ]
This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor. This coefficient accounts for the time lag between the outdoor and indoor temperature peaks.
SHGC–Solar Heat Gain Coefficient: measures the assembly's transfer of heat from outside to inside that is caused by sunlight. These properties are labeled in the U.S. as a decimal between zero and one, with lower numbers indicating lower heat transfer rates. Depending on the geographic region, optimal U-factor and SHGC performance will vary.
This can significantly reduce the solar gain of the IGU, which impacts both the thermal performance (R-value) and the Solar Heat Gain Coefficient (SHGC). Two types of low E coatings are available: hard coatings and soft coatings.

SHGC—solar heat gain coefficient; SIR—savings-to-investment ratio (energy conservation investments) SLA—Specific leakage area; SPB—Simple Payback (energy conservation investments) SSE—steady-state efficiency; U-value—thermal transmittance (also called U-factor) WF—water factor (clothes washers)
Sufficient thermal insulation is the fundamental task that ensures a healthy indoor environment and against structure damages. It is also a key factor in dealing with high energy consumption, it can reduce the heat flow through the building envelope. Good thermal insulation can also bring the following benefits to the building:
