HRAI reported in the spring 2017 that a Notice of Intent was published in the Canada Gazette, Part I on March 4, 2017 indicating Natural Resources Canada’s (NRCan) intent to proceed with the development of Amendment 15. This Amendment would introduce or update energy efficiency standards and, where applicable, test methods and associated reporting and compliance requirements for 17 product categories.

NRCan has posted a technical bulletin for air conditioners and heat pumps under 19 kW, on its website to outline the regulatory changes being considered. The notice introduces a maximum average off-mode power consumption that covers units both single phase and three-phase electric currents. Three-phase units are not included in the US Department of Energy regulations.

HRAI and AHRI have recently written to NRCan to express concerns to using the same off-mode power use requirements for single and three-phase equipment citing several reasons why it is not feasible to include three-phase equipment in this requirement.  The associations have recommended that NRCAN consider, excluding three-phase air-conditioning equipment from off-mode power requirements, or consider allowing the use of an alternative efficiency determination method (AEDM) in lieu of actual testing and/or, extending single-phase results by calculation to simulate the off-mode power consumption for all three-phase air-conditioners and heat pumps.
