This video only shows the daily thermal breathing of a house. Considering the seasonal change of temperature, we may also definite a concept “annual thermal breathing,” which describes this behavior on an annual basis.
This breathing metaphor may help students build a more vivid mental picture of the dynamic heat exchange between a house and the environment. Interestingly, it was only after I realized this thermal visualization feature in Energy3D that this metaphor came to my mind. This experience reflects the importance of doing in science and engineering: Ideas often do not emerge until we get something concrete done. This process of externalization of thinking is critically important to the eventual internalization of ideas or concepts.
