2/1/2019 National Energy Code for Buildings Introduction ‐ Five Principles Application of the National Energy Code for Buildings is guided by five principles under provision of the UBAS Act. 1) Building owners are responsible to comply. 2) Local authorities (municipalities) are responsible to administer and enforce. 3) The Government of Saskatchewan is responsible for the legislative, regulatory and policy framework. 4) Building officials work for the local authority. 5) Designers (architects and engineers) and contractors work for the building owner. National Energy Code for Buildings Introduction – UBAS Regulations – Codes Adopted 3(8) . . . The National Energy Code of Canada for Buildings, 2015 , including the errata and revisions issued by the Canadian Commission on Building and Fire Codes from time to time, is declared to be in force on January 1, 2019. NBC 2015 Section 9.36. Energy Efficiency  Adopted January 1, 2018 and in force January 1, 2019 NECB 2015  Adopted January 1, 2018 and in force January 1, 2019 NECB 2017  Available from NRC free of charge in digital format  Proposed for adoption and in force on January 1, 2019 2020 Editions  Public Review underway from November 7, 2018 to January 4, 2019 3

2/1/2019 National Energy Code for Buildings Introduction ‐ UBAS Regulations PART II General Standards Codes adopted 3 (1) In this section, “work” means any construction , erection, placement, alteration , repair, renovation , demolition, relocation, removal, use, occupancy or change of occupancy of a building. National Energy Code for Buildings Introduction ‐ UBAS Regulations PART II General Standards Codes adopted 3(8.1) Notwithstanding subsection (8), the edition of the National Energy Code of Canada for Buildings that was in force on the day which a permit was issued is deemed to be in force with respect to work : (a) for which the permit is issued before the day on which the National Energy Code of Canada for Buildings is declared to be in force or any amendment to subsections (a) comes into force; and (b) that is not completed on the day on which that edition is declared to be in force. 4

2/1/2019 National Energy Code for Buildings Introduction ‐ UBAS Regulations PART II General Standards Codes adopted 3(8.2) For the purposes of these regulations: (a) each of the subsequent editions of the National Energy Code of Canada for Buildings is deemed to be adopted on the date that is one year after the date of its being issued; and (b) subject to other provisions of these regulations, any previous edition of the National Energy Code of Canada for Buildings does not apply to any work for which a permit is issued on or after the date mentioned in clause (a). National Energy Code for Buildings Introduction ‐ UBAS Regulations PART II General Standards Codes adopted 3(9) No person who is required to comply with the Act and these regulations shall fail to comply with the National Energy Code of Canada for Buildings that is in force at the time the permit for the work to be undertaken is issued. 5

2/1/2019 National Energy Code for Buildings Introduction ‐ UBAS Regulations PART II General Standards Codes adopted 8(3.1) An owner who undertakes to construct or have constructed a building within the scope of the NECB shall have an architect or engineer complete: of: (a) the design or design review of the structure; (b) an inspection of construction of the structure to ensure compliance with the design; and (c) The reviews required by the NECB.

2/1/2019 National Energy Code for Buildings The Basics What building parameters are covered by the NECB? Division A, Article 1.1.1.2. 1) This Code contains requirements for a) the design and construction of the building envelope, b) the design and construction or specification of systems and equipment for i) heating, ventilating, or air‐conditioning, ii) service water heating, and iii) lighting, and c) the provision of electrical power systems and motors, excluding process loads. National Energy Code for Buildings NECB Application NECB applies to:  New buildings (as defined in NBC)  ALL new Group A, B, and F1 buildings regardless of size  ALL new Group C buildings greater than 600 m 2  All new Group D, E, F2, and F3 buildings greater than 300 m² or exceeding 3 storeys or of mixed occupancy (excluding parking garages serving Group C buildings)  Additions to any of the above buildings exceeding 10 m² of floor area  Major alterations to existing buildings 7

2/1/2019 National Energy Code for Buildings The Basics How is the NECB formatted?  Objective‐based  Division A – Compliance, Objectives and Functional Statements  Division B – Acceptable Solutions  Division C – Administrative Provisions  Why building design/construction is regulated in Objectives  What the design/construction of the building must do to achieve the objectives in Functional Statements • Provides Acceptable Solutions that meet the objectives and functional statements  Allows for Alternative Solutions , provided they meet the same objectives and functional statements National Energy Code for Buildings The Basics How is the code formatted? As you would expect the code is written and laid out in the same format as the building code. The technical parts (Division B) are broken out essentially by discipline: Part 1 – General Part 2 – Reserved Part 3 – Building Envelope (Architect/Engineer) Part 4 – Lighting (Electrical Engineer) Part 5 – HVAC (Mechanical Engineer) Part 6 – Service Water Systems (Mechanical Engineer) Part 7 – Electrical Power Systems and Motors (Electrical Engineer) Part 8 – Performance Compliance Path (All of the above and NECB modeler) 8

2/1/2019 National Energy Code for Buildings NECB Approach What NECB doesn’t deal with?  NECB does not deal with operation of the building including:  anything you plug into the wall  operating schedule  numbers of staff or patrons  equipment servicing or maintenance  thermostat settings or other controls  NECB does not apply to:  existing buildings not being altered  farm buildings  buildings with heating or cooling systems with output capacity < 10 W/m 2 (limitation in NECB Part 3) National Energy Code for Buildings NECB Approach  Energy used by building for NECB is Energy source neutral  NECB is based on climatic zone represented by heating degree‐days (HDD) Source: Codes Canada 9

2/1/2019 National Energy Code for Buildings NECB Approach Benefits of Code Requirements  No differentiation by  fuel source  assembly constructions  occupancy, other than residential or non‐residential  Consistent minimum energy performance  Consistent benchmark through various paths  Established based on minimum prescriptive path requirements  Changes subject to impact analysis to ensure viability  Cost of construction and incremental energy saved National Energy Code for Buildings NECB Approach Silent on renewable, waste and site‐generated energy  Wide variety of technology exists  Code does not place barriers to the use  Reference standards for use, not to measure efficiency Silent on most process loads  Except pools and ice surfaces  Performance Path includes:  Guidance  Flexibility 10
