When the shading coefficient of the whole window is 0 6, what is the shading coefficient requirement

The shading coefficient can be divided into four types, namely glass shading coefficient SE, external window shading coefficient SC, external shading coefficient SD, comprehensive shading coefficient glass shading coefficient SE (shadingcoefficient) refers to the ratio of the transmittance of the solar penetration test shading object to the standard shading object (3mm ordinary colorless transparent glass). 2. The shading coefficient sc (shadingcoefficientofexternalwindow) is the ratio of the radiant heat through the external window (including the window frame and glass) to the radiant heat through the standard window (including the window frame and 3mm thick transparent glass) of the same area under the same conditions. 3. The external shading coefficient SD (externalsolarshadingcoefficientofwindow) is the ratio of the radiant heat penetrating into the building when the glass curtain wall of the building has external shading facilities and the indoor radiant heat penetrating when there are no external shading facilities under the same conditions.

4. Integrated shading coefficient SW, (integratedshadingcoefficientofexternalwindow). The product of the shading factor of the glass and the shading factor outside the window.

Berberine is redundant and becomes sulfurous.

Shading coefficient SC = solar heat gain coefficient (SHGC) Heading ratio, shading coefficient is the ratio of the solar heat gain coefficient through a test window system to the heat gain coefficient through standard single-layer flat white glass in a given solar radiation projection angle and solar radiation band, without considering the influence of the wavelength of solar radiation bending, the calculation formula of the shading coefficient SC is as follows:

Solar heat gain coefficient SHGC: (also known as total solar transmittance, heat gain factor, g value). It refers to the ratio of the amount of solar radiation energy entering the room through the glass (including both the direct part and the heat released after absorption) and the solar heat entering the room through an opening of the same size but without glass under the same conditions.

The shading coefficient can be divided into four types, namely glass shading coefficient SE, external window shading coefficient SC, external shading coefficient SD, and comprehensive shading coefficient SW.

1. The shading coefficient (SE) refers to the ratio of the transmittance of the solar penetration test occlusion to the standard shading (3mm ordinary colorless transparent glass).

2. The shading coefficient sc (shadingcoefficientofexternalwindow) is the ratio of the radiant heat through the external window (including the window frame and glass) to the radiant heat through the standard window (including the window frame and 3mm thick transparent glass) of the same area under the same conditions.

3. The external shading coefficient SD (externalsolarshadingcoefficientofwindow) is the ratio of the radiant heat penetrating into the building when the glass curtain wall of the building has external shading facilities and the indoor radiant heat penetrating when there are no external shading facilities under the same conditions.

4. Integrated shading coefficient SW, (integratedshadingcoefficientofexternalwindow). The product of the shading factor of the glass and the shading factor outside the window.

Shading factor refers to projection through windows, including window panes, shades, and curtains.

Shading factor.

The calculation formula is: shading coefficient = solar heat gain coefficient The total solar transmittance of the standard white glass You can first measure the solar heat gain coefficient (SEGC) of the glass in addition to the total solar transmittance of the standard white glass (GB T2680 in the theoretical value, the international standard.

For example, the SHGC value of this piece of glass is, using the international standard) = is the shading coefficient of this glass.
