Which of the following is a key purpose of evaluating house leakage?

Evaluating house leakage primarily serves to assess the energy efficiency of a building. When air leaks occur in a house, they can significantly impact heating and cooling costs, as well as indoor comfort levels. Proper evaluation helps identify areas where energy loss is happening due to unwanted air infiltration or exfiltration. By ensuring that a building has effective air sealing and insulation, energy consumption can be reduced, leading to cost savings and improved environmental performance.

Understanding airflow dynamics and identifying leaks allow for the implementation of strategies to enhance the building's envelope, thus making it more energy-efficient. This focus on energy efficiency aligns directly with objectives outlined in building performance assessments and contributes to overall sustainability efforts.
