Code article
NECB Automatic Lighting Shut-off Controls
The requirements of Sentence (1) shall not apply to
a) lighting required round the clock due to operational requirements
b) lighting in spaces where patient care is rendered, and
c) lighting in spaces where an automatic shut-off would endanger the safety or security of its occupants.  

Previous direction
Current direction
The City of Calgary has been asked for clarification on the definition of spaces which operational or safety concerns would exempt them from the requirement to have automatic shut off controls to comply with the NECB. The intent of this article in the NECB is to reduce energy consumption by limiting the time which lights are left on unnecessarily. However, there are circumstances in which safety, security and building operations make this somewhat impractical.

In order to provide clear and equitable interpretation of these spaces, public corridors (as defined in the Alberta Building Code as providing access to exit for more than one suite) have been identified as a specific space type that may be exempted from the requirements laid out in NECB by application of NECB

Please note that this does not include corridors or spaces located within a suite or serving only one suite, nor would it apply to spaces that are adjacent to public corridors but not providing access to exit (i.e. those spaces that are not leading to an exit).

Note: The interpretation above represents a consensus interpretation of the NECB document as it applies to most foreseeable applications and situations. It is intended to provide clarity and guidance, but may not be applicable to every condition found in individual projects. For highly irregular or case-specific interpretation, please contact:
