Which testing standard is an option for verifying air leakage rate as per ASHRAE 90.1?

• A. ASTM E779 - 19
• B. ASTM E1827 - 11
• C. ASHRAE 62.1
• D. ASHRAE 90.2

Answer: (B)

The selected testing standard for verifying air leakage rate as per ASHRAE 90.1 is ASTM E1827. This standard provides a methodology for determining the air leakage of whole buildings, which is essential for meeting the requirements set forth in ASHRAE 90.1 for energy efficiency. ASTM E1827 specifically focuses on measuring the air leakage rate of buildings using a pressurization or depressurization method, making it a valuable tool for building professionals involved in energy compliance and performance testing. The results from this standard help ascertain whether a building meets the established air leakage thresholds, contributing to overall energy efficiency and indoor air quality. The other standards listed are relevant to various aspects of building performance and testing but do not specifically relate to the air leakage verification in the context of ASHRAE 90.1. For example, ASTM E779 provides a method for determining air leakage by the blower door test but is not cited as frequently for the purposes of ASHRAE 90.1 as ASTM E1827. ASHRAE 62.1 and ASHRAE 90.2 focus on ventilation and energy standards for low-rise residential buildings, respectively, rather than specifically addressing air leakage rate verification.
