Prescribed efficiency standards or requirements
 2. (1) The prescribed efficiency standard or requirement referred to in section 25.35.7 of the Act for an appliance or product is the efficiency standard or requirement set out in section 1 of the applicable Schedule to this Regulation. (2) Section 1 of each Schedule sets out the following information with respect to the prescribed efficiency standard or requirement for an appliance or product: Note: On January 1, 2024, subsection 2 (2) of the Regulation is amended by striking out “Section 1 of each Schedule sets out” at the beginning and substituting “Section 1 of each Schedule, other than Schedule 9, sets out”. (See: O. Reg. 350/23, s. 2 (1)) 1.  Date of manufacture:  The period during which the particular appliance or product must have been manufactured in order for the particular efficiency standard or requirement to apply. 2.  Testing standard:  The applicable testing standard for the appliance or product. 3.  Scope of application:  The appliances or products to which the efficiency standard or requirement applies. 4.  Prescribed efficiency standard or requirement:  The provisions of the testing standard or the other efficiency requirements applicable to the appliance or product. Note: On January 1, 2024, section 2 of the Regulation is amended by adding the following subsection: (See: O. Reg. 350/23, s. 2 (2)) (2.0.1) Section 1 of Schedule 9 sets out the following information with respect to the prescribed efficiency standard or requirement for an appliance or product: 1.  A description of the appliance or product to which the efficiency standard or requirement applies. 2.  The period during which the particular appliance or product must have been manufactured in order for the efficiency standard or requirement to apply. 3.  The testing and energy efficiency standards and requirements applicable to the appliance or product. O. Reg. 350/23, s. 2 (2). (2.1) Despite subsection (1), if an appliance or product identified in a Schedule to this Regulation was manufactured before the date of manufacture specified in the Schedule for the appliance or product, and on the date the appliance or product was manufactured, this Regulation prescribed efficiency standards or requirements for the appliance or product, those efficiency standards or requirements continue to apply.
