  2. Shading coefficient - Wikipedia

    en.wikipedia.org/wiki/Shading_coefficient

    It becomes less significant in situations where direct sunlight is not a major factor (e.g., windows completely shaded by overhangs). Window design methods have moved away from Shading Coefficient to Solar Heat Gain Coefficient (SHGC), which is defined as the fraction of incident solar radiation that actually enters a building through the ...

  3. Solar gain - Wikipedia

    en.wikipedia.org/wiki/Solar_gain

    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]

    Energy efficiency can often be measured in two values: u-factor and SHGC. According to experts, a window’s insulating value is called its U-factor, and lower numbers have the best insulation for ...

  5. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The SC, or shading coefficient, is used widely in the evaluation of heat gain through glass and windows. [1] [5] Finally, the SCL, or solar cooling load factor, accounts for the variables associated with solar heat load. These include the global coordinates of the site and the size of the structure.

    For a given product line, all configurations and options are modeled using THERM and WINDOW software programs, developed by Lawrence Berkeley National Laboratory. [3] One physical unit is built and then tested in a specialized heat transfer chamber. The measured u-factor must be within 10% of the modeled value in order to validate the modeling.

    The last few weeks of the year can be a busy and stressful time. Here’s how to focus on what really matters this holiday season, according to experts.

  9. Insulated glazing - Wikipedia

    en.wikipedia.org/wiki/Insulated_glazing

    This takes into account a combination of the heat loss through the window (U value, the reciprocal of R-value), the solar gain (g value), and loss through air leakage around the frame (L value). For example, an A Rated window will in a typical year gain as much heat from solar gain as it loses in other ways (however the majority of this gain ...
