Subject:
Greenhouse Gas Emissions
Title:
New Section 9.37.-2030 on Operational GHG Emissions
Description:
This proposed change moves the provisions in Subsections 9.36.15. and 9.36.16. to a new Section to separate requirements for operational greenhouse gas emissions from those for energy efficiency.
This change could potentially affect the following topic areas:

Problem

The 2025 edition of the National Building Code of Canada introduced requirements to minimize excessive emissions of operational greenhouse gases (GHGs). These requirements were included in Section 9.36., but address a different Environment Objective than energy efficiency.

Justification

Moving the operational GHG emissions requirements to their own Section would provide clarity for Code users.

Note A-9.37.2.1. Unit Conversions.
A volumetric quantity of a fuel can be converted to an equivalent amount of energy, in kWh, using the conversion factors provided in Table A-9.37.2.1.

Note A-9.37.2.1.(4)(b) and (5) Qualified Person.
A qualified person is a person with training and expertise in building energy analysis and includes (a) a GHG verifier certified in accordance with ISO/IEC 17024, “Conformity assessment – General requirements for bodies operating certification of persons,” who (i) demonstrates competence with the use of ISO 14064-1, “Greenhouse gases – Part 1: Specification with guidance at the organization level for quantification and reporting of greenhouse gas emissions and removals,” or (ii) is accredited in accordance with ISO 14065, “General principles and requirements for bodies validating and verifying environmental information,” and ISO 14066, “Environmental information – Competence requirements for teams validating and verifying environmental information,” and (b) a person qualified by the authority having jurisdiction.
Note A-9.37.3.5.(3) and (4) Thermal Energy Demand.
Thermal energy demand is the amount of heating energy that is output from all types of heating equipment.
For space heating, heating equipment includes electric, gas, hot water, and any other equipment used for the purpose of space heating and ventilation. The heating output of any equipment whose source of energy is not directly provided by a utility (electricity, gas or district) must still be counted towards TEDSH.
For service water heating, heating equipment includes electric resistance elements or gas heaters/burners of hot water storage tanks or instantaneous water heaters, heat pump water heaters, and any other equipment used for the purpose of service water heating. The heating output of any equipment whose source of energy is not directly provided by a utility (electricity, gas or district) must still be counted towards TEDSWH.

Impact analysis

This proposed change does not impact the application of requirements, but instead clarifies the objective of the requirements.

Enforcement implications

This proposed change can be enforced by the infrastructure currently available to enforce the Code.

Who is affected

Regulators, builders, designers, engineers, architects, contractors and consultants.
