What does the term "air sealing" contribute to in a building?

1. Improving electricity capacity

2. Reducing noise pollution

3. Minimizing heat transfer for energy efficiency

4. Enhancing air quality inside the building

The correct answer is: Minimizing heat transfer for energy efficiency

The term "air sealing" refers to the practice of sealing leaks and gaps in a building's envelope to prevent air leakage. This process plays a significant role in minimizing heat transfer, which directly contributes to energy efficiency. By effectively sealing cracks, openings, and other unintended air pathways, air sealing helps maintain the desired indoor temperature, reducing the need for heating or cooling systems to work harder than necessary. This leads to lower energy consumption and cost savings over time. While improving electricity capacity, reducing noise pollution, and enhancing air quality are important considerations in building design, they are not the primary functions of air sealing. Air sealing mainly focuses on controlling airflow, which is crucial for optimizing energy performance and ensuring a comfortable indoor environment while reducing energy waste.
