Table Q-1 Addenda to ANSI/ASHRAE Standard 62.1-2019 (Continued)
Addendum Section(s) Affected Description of Changes* Approval Dates
i Table 6-1; 6.2.1 Addendum i relocates Table 6-1 values related to low-risk outpatient facilities to new Normative Appendix D.
ASHRAE/ASHE Standard 170-2021 previously added a new Table 8-2 covering low-risk outpatient facilities and listing Ra and Rp values for such spaces, which supersede the values listed in Standard 62.1-2019, Table 6-1. Rather than delete the values entirely from Standard 62.1, they are relocated to accommodate building codes (e.g., International Mechanical Code®) that still do not reference Standard 170 for business occupancy (B) outpatient facilities.
p 3.1, 5.18.3.2.5, 5.18.3.3.2, 9 Addendum p modifies the 2019 term “energy recovery ventilation system” to be “energy recovery device,” as the original term was not used in the standard, and the latter term wasn’t defined.
The 2019 standard contained exceptions for leakage from “energy recovery devices,” but due to ambiguity in how the relevant terms were listed and defined, those exceptions had been misinterpreted and misapplied.
y 5.20, 9 Addendum y requires advising the owner of the basic requirements of ASHRAE Standard 188, Legionellosis: Risk Management for Building Water Systems .

Addendum aa adds a minimum requirement of percentage of people satisfied and requirements for designing to specific limits for design compounds and particulate matter. The design compounds are specifically identified. Mixtures are specifically identified. Objective and subjective testing are added.
ao Title Addendum ao revises the title of the standard, because Standard 62.1 is not a standard only about ventilation. It is about indoor air quality in general, and many requirements are nonventilation. Some of these include drain pans, frequency of maintenance activities, and combustion air requirements (see Sections 5, 7, and 8).
Editorial 5 Section 5 was reorganized editorially to reflect the path of airflow and better illustrate how buildings, systems, and equipment are related in the context of the standard. No substantive changes were made in the process.
