What is the purpose of ASTM E1827 - 11?

• A. To promote energy conservation only
• B. To verify air leakage rate
• C. To enforce structural integrity
• D. To provide guidelines for construction safety

Answer: (B)

The purpose of ASTM E1827 - 11 is to verify air leakage rate in buildings. This standard provides the methodology for conducting tests that measure how much air passes through the building envelope under specific pressure differentials. By determining the air leakage rate, stakeholders can assess the efficiency of a building's airtightness, which is crucial for energy performance, indoor air quality, and overall comfort. Understanding and verifying air leakage helps in identifying areas for improvement, ensuring compliance with energy codes, and optimizing HVAC system performance. Thus, the focus of this standard is directly related to establishing the effectiveness of the building's air barrier system.
