What can air leakage cause in a residential building?

Air leakage in a residential building allows outside air to infiltrate and conditioned air to escape, which can lead to several issues. One of the most significant impacts is the increase in energy costs. When warm or cool air leaks out of a home, the heating or cooling system has to work harder to maintain the desired indoor temperature, leading to higher energy consumption and, consequently, increased energy bills. This energy inefficiency results in wasted resources and can negatively affect the overall financial management of a household.

In contrast, options such as increased comfort and improved indoor air quality generally suggest more efficient air management, which is the opposite of the effects of air leakage. Similarly, decreasing maintenance needs is associated with a well-sealed and energy-efficient home rather than one with significant air leaks. Proper sealing and insulation are essential for maximizing a building's performance and comfort, minimizing energy costs, and ensuring healthier indoor environments.
