How to use "Emergency building"

I'm playing a standard game and in the construction queue - select Queue Settings and tick the box "Emergency Build". It will stay on for 10 turns then go to slow build for 10 turns. AFAIK you can't turn it off you have to wait until the slow build cycle finishes.

Actually, if you wait until the end, you'll get 11 turns (0.0->1.0) of emergency building for 10 turns of slow build.

I was wondering why I sometimes saw "Emergency build 0.0 yrs" - I just thought it was a bug... I guess it is :>

I think of it more as a hidden feature, one of the many small details that make the game interesting.

You forgot to mention that you can turn off Emergency build at any time prior to 10 turns and will have slow build for the number of turns you were in Emergency build.

ie. Emergency build for 4 turns
followed by 4 turns of slow build.

I didn't realise you could do that - sounds better than leaving it on when you just need to get a couple of ships built quick.

One thing I do with emergency build is where I have a planet that can only take a couple or three facilities - I always put it on emergency build - unless I'm building stuff that only takes one turn in normal mode.
