Draft Details

1.1 General

1.1.1 Scope and Application of the Standard

This Standard provides guidelines for the commissioning of buildings and all energy and domestic water-related building systems. It applies to new construction of Part 3 Buildings and new systems installed in existing Part 3 Buildings, as specified in the National Building Code of Canada (NBC). It does not apply to the commissioning or recommissioning of existing systems, which is covered by CSA Z5001.

Note: Annex I describes when to consider the application of the CSA Z5000 and CSA Z5001 standards.

1.1.2 Commissioning Scope and Requirements

This Standard is intended to assist the commissioning team in the preparation and implementation of a commissioning plan. This scope of work specifies commissioning requirements for building systems that affect GHG emissions, energy and domestic water usage, and includes, but is not limited to, descriptions of the following:

a)    the commissioning process;

b)   the resources required to complete commissioning;

c)    the responsibilities of the commissioning team;

d)   the sequence and integration of commissioning activities;

e)    the functional testing and enhanced performance commissioning of energy- and water-related building systems;

f)    planning for post-occupancy, including ongoing monitoring and maintenance, and measurement and verification activities; and

g)    analyzing and providing data to assist in determining compliance with local energy efficiency regulations.

1.1.3 Relationship to Other Standards

This Standard is intended to be complementary to CSA Z320, with additions as appropriate to address the special requirements for verifying energy and GHG emission performance during the commissioning of buildings and their systems.

Note: Annex I describes when to consider the application of the CSA Z5000 and CSA Z5001 standards.

1.2 Specific systems

1.2.1 Covered systems

The systems covered in this Standard are classified as

a) architectural and building enclosures;

b) vertical and horizontal transportation;

c) electrical and lighting;

d) mechanical and plumbing;

e) controls and building automation; and

f) energy monitoring and metering.

1.2.2 Exclusions

This Standard does not apply to

a) fire pumps;

b) smoke pressurization fans;

c) fire alarm and detection systems;

d) other life safety systems that operate only during testing or emergencies; and

e) equipment or systems exempt from the National Energy Code of Canada for Buildings (NECB).

1.3 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
