What is the net heat gain through the west glazing of the house?

To determine the net heat gain through the west glazing of a house, several factors must be considered. These include the amount of solar radiation that enters through the windows, the orientation of the glazing (in this case, west-facing), and any adjustments for shading or thermal properties of the glass.

The net heat gain calculation usually involves the total solar heat gain coefficient (SHGC), the area of the windows, and the solar radiation incident on the glazing during the specific time of day. Given that the answer provided is 2760 BTU per hour (btuh), this indicates that after considering the amount of sun exposure and any shading effects, this is the total heat gain that is occurring through the west glazing.

The number 2760 btuh reflects a scenario where there is significant sunlight hitting the west side of the house in the afternoon, when solar gain tends to be higher, especially in warmer months. Factors contributing to this value could include the size of the window, the type of glass used, and possibly the presence of any overhangs or nearby structures that might either block or intensify sunlight exposure.

Calculating net heat gain typically involves the multiplication of total solar radiation and the area of glazing, along with applying the appropriate SHGC. If
