On February 28, 2019, the Government of Canada confirmed funding that will support ongoing and future building code development work. This is good news that will allow NRC to continue to support the building code development system and to provide free access to the national model codes. Starting in spring 2019, NRC will offer free online access to the National Building Code, the National Fire Code, the National Plumbing Code, and the National Energy Code for Buildings, as well as the provincial codes published by NRC. Paper copies of the Codes, along with other supporting documents including the Guides, will be offered at a reduced cost. Due to these changes, longer term subscriptions are not currently available. Please touch base with us again in April for an update and more information.
Codes Canada publications are available in printed and electronic formats. Printing of electronic formats is limited or disabled depending on the Code edition and subscription type. See the Features page for details.

The National Energy Code of Canada for Buildings 2017 (NECB), published by NRC and developed by the Canadian Commission on Building and Fire Codes in collaboration with Natural Resources Canada (NRCan), sets out technical requirements for the energy efficient design and construction of new buildings. NRC and NRCan are publishing this interim edition of the NECB in response to proposals received that improve the overall energy performance of buildings over the 2015 edition. Modelling for these changes indicates a potential energy efficiency improvement of between 10.3 and 14.4 % over the NECB 2011.
The 2017 edition is an important step toward Canada’s goal for new buildings, as presented in the Pan-Canadian Framework, of achieving ‘Net Zero Energy Ready (NZER)’ buildings by 2030. The NECB 2017 supports this goal by reducing the overall thermal transmittance of roofs, fenestration and doors; reducing losses through thermal bridging in building assemblies; and, reducing the allowable percentage of skylight area. This new edition also introduces more stringent requirements for energy recovery systems and interior and exterior lighting requirements. It requires temperature controls in individual guest rooms in hotels and motels and demand control ventilation systems in commercial kitchens. In Part 4, it clarifies the lighting trade-off path requirements and in Part 8, it makes performance compliance requirements consistent with prescriptive requirements.
The NECB is a must-have for building designers, energy consultants and subcontractors, construction professionals and regulatory officials.
