ANSI/ASHRAE Standard 180 2018

ANSI/ASHRAE Standard 180 2018 Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems represents a complete revision of the standard. A thorough review of the 2012 edition of the standard using the continuing maintenance process resulted in improvements, revisions, and updates to the tables in Section 5. These changes were necessary to eliminate duplication, add additional tasks, list equipment tables in alphabetical order for easier reference, and consolidate similar equipment.

This document describes the minimum acceptable level of maintenance for commercial building HVAC systems. Other standards or guidance documents may establish more specific or rigorous requirements that apply to certain buildings.

These considerations, however, fall outside the scope of this standard.

The purpose of this standard is to establish minimum HVAC inspection and maintenance requirements that preserve a system’s ability to achieve acceptable thermal comfort, energy efficiency, and indoor air quality in commercial buildings.This standard written in code-intended language so it may be referenced or adopted by enforcement authorities as the minimum acceptable level of performance within their jurisdictions.A standard practice is also needed to guide maintenance of HVAC systems, because often the maintenance information supplied by manufacturers
