The correct understanding of the testing options under USACE 2012 guidelines indicates that only openings should be sealed during the airtightness testing process, not the building being in an "as operated" state. This aligns with the specific protocols set forth in the guidelines, which are designed to ensure that the testing accurately reflects the building's potential air leakage rather than conditions that could distort results.

In typical scenarios, sealing all components of a building and preparing them as if they were in usual operational conditions could lead to misleading results, as it may not represent realistic air movement and leakage that occur during regular use. By sealing only the openings, the testing can more effectively measure the air-tightness of the building in a controlled manner, ensuring that results are valid and applicable to the actual conditions expected during everyday operation. This focus on openings ensures that any operational features of the building do not skew the test outcomes, which is crucial for accurate assessment and building performance evaluation.
