= Shading coefficient
{wiki=Shading_coefficient}
The shading coefficient (SC) is a measure used in the field of building design and HVAC (heating, ventilation, and air conditioning) engineering to assess the effectiveness of shading devices in reducing solar heat gain through windows and other glazed areas. It is a ratio that compares the solar heat gain through a window or a glazed area with and without shading devices to the solar heat gain through a standard reference window under the same conditions.
