ASHRAE STD 100
Energy Efficiency in Existing Buildings
|Publication Date:||26 February 2021|
Standard 100-2018 Section 6.3 sets out the overall requirement for the implementation of the operations and maintenance (O&M) program. A minor revision to this section clarifies that Normative Annex L focuses on the process and procedures for establishing and implementing the O&M program.
Standard 100-2018 Normative Annex L is based on ASHRAE/ACCA Standard 180-2012, Standard Practice for the Inspection and Maintenance of Commercial Building HVAC Systems, Section 4, "Implementation." This section in Standard 180 presents an excellent outline of what constitutes a good maintenance program that would be applicable to all building systems. SSPC 100 decided to adopt Standard 180, Section 4, as the requirement for its O&M program requirements. Where Standard 180 refers to "HVAC systems," Normative Annex L in Standard 100 refers to "all building systems." Other than these changes, Normative Annex L is identical to Section 180-2012 Section 4.
Since Standard 100-2018 was approved for publication, a revised edition of Standard 180 has been published. In the revised Standard 180-2018, Section 4, "Implementation," has been revised fairly extensively. Addendum a replaces the existing Normative Annex L in Standard 100-2018 with a new one based on Standard 180-2018 Section 4.
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
