Excessive heat gain in a building typically leads to higher cooling costs. When a building accumulates more heat than it can efficiently dissipate, the cooling system must work harder and run for longer periods to maintain a comfortable indoor environment. This increased demand for cooling directly corresponds to higher energy consumption, resulting in elevated utility bills.

In addition to increasing costs, excessive heat gain can create discomfort for occupants, potentially leading to a reliance on cooling systems that aren't optimized, which could affect overall energy efficiency. Ultimately, managing heat gain through effective insulation, shading, and ventilation is essential for maintaining both comfort and economical energy use in a building.
