True or False: ASTM E779 is intended for larger buildings.

True or False: ASTM E779 is intended for larger buildings.

• A. True
• B. False
• C. Only for residential buildings
• D. Only for commercial buildings

Answer: (B)

ASTM E779 is a standardized test method for determining the air leakage rate of buildings through the use of pressurization or depressurization techniques. This standard is not limited to larger buildings; it is applicable to a wide variety of building types, including residential, commercial, and industrial structures. The correct response indicates that the statement is false, as ASTM E779 can be used for all sizes of buildings, and it does not specifically target larger buildings. This flexibility makes it an essential tool for assessing airtightness in diverse construction settings, ensuring that the necessary data on air leakage is accessible for both small and large structures alike.
