How much air can a typical home lose due to air leaks?

A typical home can lose a significant amount of conditioned air due to air leaks, with estimates often indicating that this can be 30% or more. This level of air leakage can have a considerable impact on energy efficiency, leading not only to higher utility bills but also to discomfort within the home due to temperature imbalances.

Understanding the extent of air leakage is crucial for home performance assessments and energy audits. It highlights the importance of sealing air leaks and improving insulation, as reducing this loss can lead to substantial savings and improved indoor air quality. Addressing these leaks is an essential part of energy-efficient building practices, making it vital to recognize and mitigate air leakage as a significant issue in residential buildings.
