"Canadian Standards Association Z320 commissioning standard brings needed 'holistic' approach"
- Daily Commerical News & Construction Record. Read more.


This is the first edition of CSA Z320, Building commissioning. This Standard provides guidelines for the commissioning of buildings and all related building systems, and has been developed to deal with buildings and/or their major systems as a whole, rather than as separate individual stand-alone components. It applies to new construction and to renovations of existing buildings or facilities.

The intent of this Standard is to provide a comprehensive, integrated, consistent, and managed process to ensure and document the performance of a complete building and its major systems in meeting the basis of design and operational requirements of the owner.

Major building systems included are:

  • architectural systems (building envelope and interior space assemblies that are environmental separators);
  • vertical and horizontal transportation systems;
  • electrical systems (incoming, main, and branch distribution; fire alarm and detection systems);
  • mechanical systems (HVAC, plumbing, fire protection, and refrigeration); and
  • control systems and integration (BAS, energy management control systems, lighting control systems).

This Standard has been developed to assist the commissioning team in the preparation and implementation of a commissioning plan. A commissioning plan specifies commissioning requirements for newly installed or renovated building systems and includes, but is not limited to, descriptions of the following:

  • the commissioning process;
  • the resources required to complete commissioning;
  • the responsibilities of the commissioning team; and
  • the sequence and integration of commissioning activities.

The intended users of the standard may include workers and professionals who perform technical functions associated with any of these phases of operation as well as stakeholders who have an interest in building safety or related quality assurance, (i.e. developers, general contractors, property marketers, regulators, commissioning providers and consumers). The standard may also facilitate certification to green building rating systems.

The Technical Committee has developed non mandatory annexes (written in mandatory language) to provide further explanatory information. Included in these annexes are sections on recommissioning and retro-commissioning.

Note: Mandatory language will allow an individual/organization to reference an annex as a project specification.

Electronic Checksheet Application:

The Z320 Electronic check sheet Application is designed to accompany the Standard and provides access to check sheet templates in Microsoft® Excel that can be updated, completed, saved locally, and printed. The application allows for one-time set-up of company and project specific details applied to all the check sheets you create, saving you time and energy in your check sheet development process. The application provides ease of modifying some of the more complex check sheets by answering simple questions that result in the addition or deletion of appropriate check sheet sections removing the guess-work and manual manipulation from your editing.

Check sheet templates are available for major building systems including Mechanical, Electrical, and Control Systems and Integration. The check sheets are used to document the inspections and tests associated with static verification, start-up, and functional performance testing as applicable.

Where an internet connection is available, updates will be retrieved and you will be prompted to install the latest published updates from CSA. The Z320 Checksheet Application is sold here for single user access. Multi-license purchasing options are available to meet the needs of larger organizations. Please contact us for details.
