What is meant by 'continuous maintenance' in ASHRAE Standard 62.1-2022?

• A. It refers to the ongoing process of updating the standard via addenda and interpretations.
• B. It refers to the building maintenance schedule.
• C. It implies the standard is updated every year automatically.
• D. It refers to filtration maintenance.

Answer: (A)

Continuous maintenance means the standard is kept current between major revisions by issuing addenda and interpretations. Addenda are formal updates that modify specific requirements or clarify how they apply, while interpretations provide official guidance on applying the standard to real-world situations. This process lets ASHRAE incorporate new research and practical experience without waiting for a whole new edition, so the requirements stay up to date as conditions change. It’s not about the building’s maintenance schedule, automatic yearly updates, or filtration upkeep.
