Introduction
In Canada, provincial and territorial governments regulate building design and construction within
their jurisdictions. The Construction Codes Act (the CC Act) establishes the framework for
developing, adopting and implementing building, plumbing and energy codes. The Fire Safety Act
(the FS Act) provides for the fire-safe operation of buildings after construction is complete.

Consolidated versions of each regulation are published at
https://publications.saskatchewan.ca/#/freelaw.

       not be located where it can discharge into:
           (a) a sink or lavatory,
           (b) a fixture into which an outlet from a potable water system is discharged, or
           (c) a fixture that is used for the preparation, handling or dispensing of food, drink or
           products that are intended for human consumption.
       2) Sentence (1) does not apply to waterworks authorized to supply water for hygienic use
       within the meaning of section 20 or 21 of The Waterworks and Sewage Works Regulations”.
15 The following Sentence is added after Sentence 2.7.1.1.(5):
   “6) Where a non-potable water system that utilizes sewage is installed, it shall conform to CSA
   B128.3:23, ‘Performance of non-potable water reuse systems’ and produce an effluent with a
   water quality suitable for the use to which it is put”.”

National Energy Code for Buildings 2020
The Energy Code (Adoption of Code) Amendment Regulations, 2023 came into force
January 1, 2024.

These regulations amended The Energy Code Regulations to:

•   Adopt the 2020 edition of the National Energy Code of Canada for Buildings (NECB)stablish
    energy efficiency standards for the construction of large buildings in Saskatchewan at Tier 1,
    effective January 1, 2024, which is approximately 10 per cent more efficient than current
    requirements
•   Create a single climate zone for Saskatchewan to simplify energy efficiency requirements for
    individuals and industry
•   Clarify that the NECB does not apply to buildings for which construction started before
    January 1, 2019
•   Make other minor amendments to the regulations

Specific amendments to the NECB 2020 are contained in the Appendix of the regulations. These
amendments came into force on January 1, 2024.

                              Amendments to the National Energy Code
                                   of Canada for Buildings 2020

1 The National Energy Code of Canada for Buildings 2020 is amended in the manner set forth in
this Appendix.
2 Division A, Article 1.2.1.1. is repealed and the following substituted:
  “1) Compliance with this Code shall be achieved, effective January 1, 2024, by:
      a) complying with the applicable acceptable solutions in Division B (see Note
      A-1.2.1.1.(1)(a)) for the Tier 1 requirements of Part 10 for climate zone 7A; or
      b) using alternative solutions that will achieve at least the minimum level of performance
      required for the Tier 1 requirements of Division B for climate zone 7A in the areas defined by
      the objective and functional statements attributed to the applicable acceptable solutions
      (see Note A-1.2.1.1.(1)(b)).
 2) For the purposes of compliance with this Code as required in Clause (1)(b), the objective and
 functional statements attributed to the acceptable solutions in Division B shall be the objective
 and functional statements referred to in subsection 1.1.2 of Division B.”
3 Division B, Article 10.1.2.1. is repealed and the following substituted:
 “1) Compliance with this Part shall be achieved by designing and constructing buildings in
 accordance with the Energy Performance Tier 1 specified in Table 10.1.2.1., for climate zone 7A
 corresponding to:
     a) the annual energy consumption of the proposed building, expressed as a percent building
     energy target; or
     b) the percentage of improvement of the annual energy consumption of the proposed
     building relative to the building energy target of the reference building, expressed as a
     percent improvement.
 2) Compliance of the proposed building with the Energy Performance Tier 1 specified in Table
 10.1.2.1. for climate zone 7A shall be determined by modeling the proposed and reference
 buildings in accordance with Part 8 to establish the annual energy consumption of the proposed
 building and the building energy target of the reference building then:
     a) dividing the annual energy consumption of the proposed building by the building energy
     target of the reference building to derive the percent building energy target; or
     b) subtracting the annual energy consumption of the proposed building from the building
     energy target of the reference building and dividing the result by the building energy target
     of the reference building to derive the percent improvement.
 (See Note A-10.1.2.1.(2).)”.”
