General information
Problem
Division C of the National Energy Code of Canada for Buildings (NECB) requires that the authority having jurisdiction be provided with adequate documentation and other information, such as drawings and equipment specifications, in order to verify compliance with the Code. With the introduction of requirements for the alteration of existing buildings in the NECB 2025, there will be a need for information and calculations related to the extent of the alterations.
Failure to provide adequate documentation and level of detail regarding the alterations would make it difficult for authorities having jurisdiction to verify that the proposed alterations conform to the Code. This situation could also lead to inconsistency in the design, construction and performance of the alterations, which could cause confusion and conflict between designers, manufacturers, authorities having jurisdiction and the legal community.
These conflicts would occur when
- authorities having jurisdiction request documentation during permit reviews to prove Code compliance,
- designers require Code compliance for use of their design specifications on a project, or
- disputes arise which require litigation.
Justification
Providing administrative guidance in Division C on the proper reporting techniques for documentation and calculations related to the alteration of existing buildings for compliance with the NECB is necessary to ensure building officials are provided with an appropriate level of detail to assess Code compliance.

Impact analysis
Administering the enforcement of the Code is the normal business of the existing enforcement infrastructure. The enforcement of these administrative requirements is not expected to be time-consuming or add significantly to the workload that is the normal course of business for building inspectors. The overall impact would be a significant improvement in the ability of authorities having jurisdiction to successfully verify Code compliance.
Enforcement implications
The enforcement of the administrative requirements for the alteration of service water systems in existing buildings can be accomplished with the same means and resources involved in the enforcement of NECB Part 6. However, there could be an increase in enforcement and permit-review responsibilities.
Requiring information about alteration work would facilitate enforcement.
Who is affected
Designers, specification writers, manufacturers, contractors, building owners and building officials.
