What is the net summer heat gain through the west windows in bedroom 2?

To determine the net summer heat gain through the west windows in a specific room, several factors need to be considered, including the solar heat gain coefficient (SHGC) of the glazing, the area of the windows, shading provided by overhangs or trees, and the angle of the sun's rays during summer months.

The correct answer of 1840 BTUh suggests that this calculation reflects an appropriate consideration of these factors. In general, west-facing windows can experience significant heat gain in the afternoon when the sun is most intense, especially during the summer months. The glass properties impact how much heat is transmitted into the room, and if calculations have been done accurately, they would yield a value that reflects the effective heat energy increase due to solar radiation.

Additionally, if this was derived through specific mathematical models such as using the window size in square feet, the SHGC, and the incident solar radiation figures based on location and orientation, the result would be considered sound. This answer indicates a well-rounded approach to understanding the dynamics of heat transfer in building spaces during specific seasons.

The other options likely do not correlate with the correct calculations based on the parameters mentioned, leading to lower or higher values that do not accurately represent the conditions affecting the net summer
