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 2015 (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. The NECB 2015 includes over ninety changes improving the overall energy performance of buildings over the 2011 edition.
The 2015 edition broadens the scope to address all service water and introduces requirements for pressure-sensing controls which reduce the short-cycling of booster pumps when demand for water is low. Other HVAC and service water changes include equipment efficiency regulation of heat rejection equipment, such as cooling towers and (standalone) condensers, heating performance requirements for gas-fired outdoor packaged units and updated minimum pipe and duct insulation requirements. Lighting power density values and controls have been updated with more stringent lighting allowances and additional requirements for common spaces and exterior applications. The performance path modeling rules and guidance have been updated to reflect the changes to the prescriptive path as well as more current typical use profiles of buildings. Application of the code for residential and small buildings has also been clarified.
The NECB 2015 has been re-organized to consolidate relevant information. Each Part now contains the Prescriptive Requirements, followed by the Attribution Table and related (appendix) Notes.
The NECB is a must-have for building designers, energy consultants and subcontractors, construction professionals and regulatory officials.
