Quebec energy code adoption
Quebec adopts the national energy code framework with amendments. Confirm the edition and amendments in force for your permit.
Quebec building code question
What are the Quebec building code requirements for energy efficiency?
Quebec has its own energy efficiency requirements for buildings through its adoption of the NECB with amendments and the Regulation respecting energy conservation in new buildings. Quebec's cold climate and distinct regulatory framework create compliance requirements that differ from other provinces.
Energy efficiency in Quebec buildings is governed by the province's adoption of the National Energy Code with Quebec-specific amendments. Quebec's cold climate zones and distinct regulatory approach through the RBQ create requirements that may differ from neighbouring provinces. Hydro-Québec's electrical heating dominance also influences how energy performance is measured and valued compared to gas-heated provinces.
What to check first
- Quebec adopts the national energy code framework with province-specific amendments for energy efficiency.
- The province's cold climate zones (predominantly Zone 6 and 7) drive stringent insulation and air tightness requirements.
- Quebec's electrical heating dominance through Hydro-Québec influences energy performance expectations differently from other provinces.
Jurisdiction notes
Cold climate requirements
Most of Quebec falls in climate zones 6 and 7, resulting in more stringent insulation and air tightness requirements than milder provinces.
Electrical heating context
Quebec's reliance on hydroelectricity for heating affects how energy performance is evaluated and what mechanical systems are commonly used.
Work through it in this order
- Identify the energy code edition adopted by Quebec at the time of your permit application.
- Determine the climate zone for the project location within Quebec.
- Select the applicable compliance path and verify the insulation, air tightness, and mechanical system requirements.
- Document the specific code clauses and Quebec amendments that set the energy performance targets.
Common questions
Does Quebec use the BC Energy Step Code?
No. The Energy Step Code is specific to British Columbia. Quebec uses its own adoption of the national energy code framework with Quebec amendments.
Are Quebec energy requirements stricter than other provinces?
Quebec's cold climate zones (6 and 7) result in more stringent insulation requirements than milder provinces, but the regulatory approach also differs.
How does electrical heating affect energy code compliance in Quebec?
Quebec's reliance on hydroelectricity for heating influences mechanical system design and energy performance calculations compared to provinces where gas heating is common.
