In the context of the USACE 2012 standards, the pressure used for reported leakage is 75 Pa. This specific pressure is significant because it is the standardized measurement at which building airtightness is evaluated. The 75 Pa baseline allows for consistency in testing across various buildings, ensuring that results are comparable regardless of external factors like wind conditions or temperature variations.

Utilizing 75 Pa provides a realistic representation of airtightness as it simulates typical indoor pressure conditions in a building while also allowing for an effective differentiation between buildings based on their performance in containing unconditioned air and preventing heat loss. This measurement helps in assessing compliance with energy efficiency requirements and other building codes aimed at improving indoor air quality and reducing energy consumption.

Adoption of this standard helps practitioners implement effective sealing strategies and informs designers and builders about the expected performance of their structures regarding air leakage. By focusing on 75 Pa in reporting, stakeholders can accurately gauge the effectiveness of their airtightness measures in accordance with established standards.
