This phenomenon results in unequal cooling costs depending on location within a building. For residents on higher floors, more energy is needed to maintain comfort because they are exposed to the cumulative heat emissions from all the units below.
Visualizing this, the heat expelled from air conditioning units can be likened to "a lighter with a little flame"—a vivid metaphor illustrating the continuous release of heat into the environment. These unprotected areas become "pockets" of heat, contributing to the city’s overall warming.
