Its intent is to provide consistent practicesfor inspecting and maintainingHVAC systems in commer-cial, institutional, and other buildings. For the public good,it is essential thatthe HVAC systems in all buildings wherepeople work, visit, or reside support a high quality indoorenvironment that is 180 describes the minimum acceptable level ofmaintenance for commercial buildingHVAC systems. Otherstandards or guidance documents may establish more spe-cific or rigorous requirements that apply to certain build-ings.

8 Where applicable, those requirements should befollowed or considered (ifguidelines).Currently, Standard 180 is in continuous maintenance status. A thorough reviewof the Standard under the continu-ous maintenance process has resulted in improvements, revi-sions, and updates to the tables in Section 5. This document isan Addendum to theoriginal Standard . The changes weredeemed necessary in order to eliminate duplication, listequipment tables in alphabetical order for easier reference,and consolidate similar equipment where Standard is written in code-intended language so itmay be referenced oradopted by enforcement authorities asthe minimum acceptable level of performance within :Thisstandardisspecificallyfocusedonthei mpactsof maintenance onoccupant thermal comfort, indoor air qual-ity, and energy efficiency. Additional maintenance programconsiderations related to equipmentreliability, equipmentrobustness, and minimizing overall maintenance costs arealso appropriate in order to support sustainability efforts,protect the HVAC capital investment, and/or minimize systemdowntime.
