The 2012 edition combines Stan-dard 180-2008 and approved and published Addendum a tothe 2008 edition, thereby providing an easy-to-use consoli-dated Standard . Specific information on the contents of theaddendum and the approval dates are included in Informa-tive Appendix 2012 edition was updated using the continuousmaintenance process. A thorough review of the standardunder the continuous maintenance process resulted inimprovements, revisions, and updates to the tables inSection 5. The changes were deemed necessary in order toeliminate duplication, add additional tasks, list equipmenttables in alphabetical order for easier reference, and consol-idate similar equipment where 2012 edition will be updated on a five-year cycleusing the periodic maintenance 180 was created in a collaborative effortbetween ASHRAE and Air Conditioning Contractors ofAmerica ( acca ).

9 Its intent is to address the often inconsis-tent practices for inspecting and maintaining HVAC systemsin commercial, institutional, and other buildings where thepublic may be exposed to the indoor environment. Currentpractices in such buildings vary widely. Many facilitieschoose to follow rigorous policies that maintain the systemin new or nearly new condition. Others either lack policy inthis area or have adopted a run-to-failure approach, wherethe system or components of the system are attended to onlywhen there is a provide consistency and improve the thermal com-fort, energy efficiency, and indoor air quality of commercialHVAC systems, a Standard practice for their inspection andmaintenance is needed. When there is no routine inspectionand subsequent adjustment or maintenance of system com-ponents, the system is typically found operating outside itsoptimum performance parameters. When systems are notmaintained, they do not continue to provide the level of workthey were designed Standard practice is also needed to guide maintenanceof HVAC systems because the maintenance information oftenprovided by manufacturers applies only to the discrete com-ponents that they provide rather than to the entire document considers the integration of those componentsand the way they interact as well as each component the public good, it is essential that the HVAC sys-tems in all buildings where persons work, visit, or reside sup-port a high-quality indoor environment.

10 In addition,sustainability mandates that those conditions be maintainedin as energy efficient a manner as document describes the minimum acceptable levelof maintenance for commercial building HVAC standards or guidance documents may establishmore specific or rigorous requirements that apply to cer-tain buildings. Where applicable, those requirementsshould be followed or considered (if guidelines). This docu-ment is not intended to limit the level of service provided orrecommendations made by a service provider. Those deliv-ering HVAC maintenance are encouraged to consider andrecommend energy conservation measures or technologyimprovements that would help maintain or increase ther-mal comfort, the energy efficiency of the HVAC system, andindoor air of the information that will be required to preparethe maintenance program that is mandated by this standardcan most conveniently be obtained from the building com-missioning (recommissioning or retrocommissioning) docu-ments.
