1.1 General 

1.1.1 Application 

This Standard provides guidelines for the commissioning of energy and water systems in existing Part 3 buildings, as defined in the National Building Code of Canada (NBC). This Standard addresses the special requirements for verifying energy and water performance during the commissioning of existing buildings. The commissioning of new systems in existing buildings may reference the commissioning requirements of CSA Z320 and CSA Z5000.

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

1.1.2 Scope of work 

This Standard is intended to assist the commissioning team in the planning and implementation of the scope of the commissioning work. This scope of work specifies commissioning requirements for systems that affect energy and water usage, and includes, but is not limited to, the following:

a)      the owner’s Current Facility Requirements ( CFR);
b)      the development of the commissioning plan;
c)       the resources required to complete commissioning;
d)      the responsibilities of the commissioning team;
e)      the sequence and integration of commissioning activities;
f)       the investigation and testing of energy and water related building  systems;
g)      the use of metering and monitoring systems;
h)      the measurement and reporting to be put in place to confirm on-going compliance with local energy and water efficiency regulations.

1.2 Specific systems 

1.2.1 Classification 

The systems covered in this Standard are classified as

a)      architectural and building envelope;
b)      vertical and horizontal transportation;
c)       electrical and lighting & related controls;
d)      mechanical & related controls;
e)      energy and water monitoring and metering; and

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.
