In yesterday’s post, I shared the updated Occupant Load Estimator, and I mentioned a new estimator to be posted today. The new tool is the IBC and NFPA Egress Capacity Estimator, and it is available on the Tools menu above.^
I want to make sure both estimators function in a way that is easy(ish) to understand, considering the inherent complexity of door-related code requirements. I’m hoping that you’ll be willing to share some feedback so I can make any needed improvements.
To give a little background, both calculations are fairly simple, once you figure out the occupant load factor/egress capacity factor. But the fact that thousands of people have used the occupant load calculator has me pleasantly surprised – this seems to be something that is needed.
Calculating the required egress capacity is a little more complicated, even though the formula is not. There are other factors that come into play, like the required number of exits, the limits on travel distance, common path of travel, remoteness of exits, etc. The egress capacity is really just one part of the equation. It can determine how many building occupants can be accommodated by a particular door or doors, or how many inches of egress width are needed in order to serve a certain number of people.
Please check out the new estimator and let me know what you think. I can make modifications so that it is easier to use and/or understand.
I appreciate you!

Using IBC 2024, the fire alarm system has to be voice evac? And not just a plain old noise maker?
“”an emergency voice/alarm communication system in accordance with Section 907.5.2.2.“””
And maybe not use it for large gathering locations? A 40,000, occupant load or say a 150,000 occupant load. Just some example numbers
A great tool! Saves trying to do math in your head. And, a great check tool when looking at a set of plans.
Thanks Charles! I’m not a fire alarm expert, so I’ll just stick with the doors and hope that someone has looked at the fire alarm requirements! 🙂

This seems stupid easy (in a good way). Have you checked this against the normal way?
Yes, I’ve done some testing on it.
