Commercial refrigeration equipment (self-contained and remote) – May 2016

Technical bulletin on amending the standard

Webinar - June 2016

On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to align Canada’s EnergyEfficiency Regulations (the Regulations) for commercial refrigeration equipment (CRE) with standards in the United States. This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for CRE.

Input received during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.

Background

Self-contained CRE was first regulated in Canada in 2007. On January 9, 2009, the U.S. DOE issued a final rule, which increased the stringency of the minimum energy performance standard (MEPS) for self-contained CRE and expanded the scope of the CRE definition to include equipment with remote condensing units.

Natural Resources Canada (NRCan) intends to propose expanding the scope of the CRE definition to include equipment with remote condensing units.  If implemented, this proposal would ensure that Canadian regulations for CRE are aligned with those of the U.S. DOE, as finalized on January 9, 2009.  For the purposes of this bulletin, these levels will be referred to as “Tier 1”.

In March 28, 2014, the U.S. DOE issued a final rule, which increased the stringency of the MEPS for all CRE. NRCan intends to align with MEPS and effective date similar to the March 28, 2014 DOE final rule for CRE, pending the U.S court ruling. If the court decision is made before publication of this amendment, NRCan will consider aligning according to the settlement provisions. Otherwise, this proposal will be considered in a future amendment. For the purposes of this bulletin, these levels will be referred to as “Tier 2”.

Product description

The proposed Regulations would apply to self-contained CRE and CRE with remote condensing units.

Self-contained CRE are those that are equipped with a factory-made assembly of refrigerating components designed to compress and liquefy a specific refrigerant that are an integral part of the refrigerated equipment.

CRE with remote condensing units are those that are equipped with a factory-made assembly of refrigerating components which consists of one or more refrigerant compressors, refrigerant condensers, condenser fans and motors, and factory supplied accessories that are remotely located from the refrigerated equipment.

Energy performance test procedure

NRCan is proposing that the following energy performance test procedure be referenced:

  • CSA C657-15 - Energy performance standard for commercial refrigeration equipment

The test procedure can be ordered from:

Effective date

These Regulations will come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan intends to propose that the Tier 1 standards for Remote Condensing unit CRE apply to products manufactured on or after January 1, 2012 and before March 27, 2017. The effective date for the Tier 2 standards would be applied to all CRE products manufactured as of March 27, 2017, pending U.S court ruling.

Labelling requirements

NRCan is not proposing a mandatory label for CRE at this time.

Verification requirements

NRCan proposes that these products carry a third party verification mark indicating that the product meets the MEPS (i.e. new requirement for CRE with remote condensing units) and that the information to be reported has been verified. 

The verification mark is the mark of a Standards Council of Canada accredited certification body that operates an energy efficiency certification program for the product.

Reporting requirements

Energy efficiency reports

The energy efficiency report required for CRE will include the following product specific information:

  • name of product (i.e. CRE)
  • brand name
  • model number
  • name of the manufacturer
  • name of the certification body whose verification mark will be affixed to the product
  • Edaily
  • equipment class designation and the corresponding value for V or TDA, as applicable
  • if it is tested at its lowest temperature setting, the integrated average temperature at the lowest temperature setting

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.

Import reports

A dealer who imports these products into Canada must include the following information on the customs release document:

  • name of product
  • model number
  • brand name
  • address of the dealer importing the product
  • purpose for which the product is being imported (i.e. for sale or lease in Canada without modification; for sale or lease in Canada after modification to comply with energy efficiency standards; or for use as a component in a product being exported from Canada)

Comments invited

The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for commercial refrigeration equipment.

Additional information on Canada’s Energy Efficiency Regulations including a current list of Standards Council of Canada accredited certification bodies can be found in the Department’s website.
