In my memory it doesn't, but a continuous load is defined in Article 100. It's likely that it would apply to office lighting.

Welcome to the forum. :)
 
where in the code book does it refer to office lighting being a continouos load?

Basically, Art. 100 Definitions.
Continuous Load. A load where the maximum current is expected to continue for 3 hours or more.

You won't find a 'shopping list' of items that are or aren't considered continuous.
 
Here are a few items the NEC does qualify as Continuous Loads:
422.13 Storage-Type Water Heaters
424.3(B) Branch-Circuit Sizing. Fixed electric space heating equipment
426.4 Continuous Load. Fixed outdoor electric deicing ans snow-melting equipment
427.4 Continuous Load. Fixed electric heating equipment for pipelines and vessels
625.14 Rating. ...for the purpose of this article, electric vehicle charging loads shall be considered to be continuous loads



In Annex D, there are examples of calculations.
Some of the calculations show lighting as a continuous load.
Example D3 Store Building is one of those
 
Allen, let's try not to hijack this thread. Your question has been answered in the other thread.
