Reduced walking speed with low visibility?
« on: January 25, 2017, 09:46:24 am »

Hi

The information I am trying to aqquire might be somewhere in this forum, but I havnt found it. Please link related threads.

In large underground systems occupants are required to walk long distances in smoke to reach an exit. It wouldnt be economically justified to build largre underground stations using the citeria for when evacuation is deemed unaccepteable as in when designing above ground buildings. Hence much easier critera for when evacuation is deemed unaccepteable is used in large underground buildings. To get a more accurate simulation I therefore want to affect occupants walking speed when the visibility is low . Is it possible to do that using a visibility slice file from FDS?

Thanks in advance!
