Porté:

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 (nonmandatory) to define their application.

 

Raison d’être du projet

The absence of a nationally recognized testing standard for performance verification has been a deterrent to promote Horizontal drain water heat recovery (DWHR) systems as an energy efficient product in the marketplace. Many new and existing buildings are unable to utilize current certified vertical DWHR systems such as: buildings without basements, shallow foundations, homes on permafrost, MURBS. The development of a testing standard for horizontal units would provide additional options to meet the demand of the marketplace with approved and safe low-slope horizontal DWHR systems. Establishing a nationally accepted testing procedure for low-slope Horizontal DWHR devices will provide recognized standards that will increase the confidence of consumers and authorities having jurisdiction in this emerging technology by verifying manufacturer's claims on system performance and provide a level playing field for the various manufacturers to develop and promote their products. Once a testing standard will be established, it will be easier for individual consumer and local authorities to integrate this energy efficient technology and to benefit from the savings generated. The combination of increased consumer confidence with the backing of a utility energy efficiency program to a new technology has been proven to increase market penetration as demonstrated by previous energy efficiency programs.

Note : L’information ci-dessus a été recueillie et est diffusée par le Conseil canadien des normes (CCN) pour les besoins de son système de notification centralisé et transparent pour l’élaboration de nouvelles normes. Le système permet aux organismes d’élaboration de normes (OEN) accrédités par le CCN et aux membres du public d’être informés des nouveaux travaux d’élaboration de normes au Canada. Il donne aussi aux OEN accrédités la possibilité de repérer et de résoudre les cas de doubles emplois éventuels dans les normes et les travaux de normalisation.

Les OEN sont eux-mêmes responsables du contenu et de l’exactitude de l’information présentée ici. Cette information n’existe que dans la langue dans laquelle elle a été fournie au CCN.
