What impact does air leakage have on a home’s energy efficiency?

Air leakage significantly impacts a home's energy efficiency by allowing conditioned air to escape and unconditioned air to enter. When warm or cool air exits the home through leaks, the heating and cooling systems must work harder to maintain the desired indoor temperature, leading to increased energy consumption. This not only results in higher utility bills but also creates discomfort due to drafts and inconsistent temperatures within the living space.

In addition, uncontrolled air leakage can lead to moisture infiltration, which can cause problems such as mold growth and deterioration of building materials. Therefore, addressing air leakage through proper sealing and insulation strategies is essential for improving a home's overall energy efficiency and comfort. Ensuring an airtight home contributes to optimal energy usage, which is a key goal in energy-efficient building practices.
