1 Domaine d’application

1.1  

Cette norme énonce les exigences relatives aux vérifications et aux essais qui s’appliquent aux travaux effectués par toute organisation participant à la construction, à la fabrication ou à l’installation d’enceintes de confinement en béton, y compris, sans s’y limiter, les éléments structuraux et non structuraux suivants :

a) le béton;

b) les armatures (précontraintes et non précontraintes);

c) l’acier (p. ex., membrane protectrice, pièces noyées, ancrages);

d) les systèmes de revêtement non métallique et de revêtement;

e) les mastics de jointoiement; et

f) les éléments nécessaires à une enceinte de confinement (p. ex., fondations).

1.2  

Cette norme énonce les exigences relatives à la qualification du personnel pour les travaux de vérification et d’essai des enceintes de confinement en béton des centrales nucléaires.

1.3  

Cette norme peut s’appliquer, s’il y a lieu, aux installations nucléaires visées par la Loi sur la sûreté et la réglementation nucléaires du gouvernement du Canada.

1.4  

Cette norme est utilisée conjointement avec les normes suivantes, le cas échéant :

a)   La CSA N287.1, qui énonce les exigences générales relatives aux enceintes de confinement en béton des centrales nucléaires; et

b)   La CSA N287.8, qui énonce les exigences relatives à la gestion du vieillissement des enceintes de confinement en béton des centrales nucléaires.

1.5  

Dans les normes CSA, le terme « doit » indique une exigence, c.-à-d. une prescription que l’utilisateur doit respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.

Les notes qui accompagnent les articles ne comprennent pas de prescriptions ni de recommandations. Elles servent à séparer du texte les explications ou les renseignements qui ne font pas proprement partie de la norme.

Les notes au bas des figures et des tableaux font partie de ceux-ci et peuvent être rédigées comme des prescriptions.

Les annexes sont qualifiées de normatives (obligatoires) ou d’informatives (facultatives) pour en préciser l’application.

1 Scope 

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
f)       water using systems.

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.

1 Scope

1.1 General

1.1.1

These procedures apply to unitary air conditioners and heat pumps that are

a) factory-made;
b) air-source and air-sink;
c) single-split systems with matching assemblies or single package for use in ducted and/or non-ducted distribution systems;

d) intended for space-heating and/or air-conditioning applications in buildings;
e) electrically driven, mechanical, vapour-compression-type systems; and
f) rated below 65,000 Btu/h (19.0 kW) heating or cooling at standard rating conditions, in accordance with Clause 5.2.

Note: This includes space-constrained single-package or split-system and small-ducthigh-velocity central air conditioners and heat pumps matching assemblies of the type classified in Clause 1.2 and intended for air-conditioning and space-heating applications in buildings.
