However, I could replace another event building if calculations prove this new one is more efficient than the existing one I have placed.
One other might be if you don't manage to gather enough Artifacts to fully evolve it. I assume the math is assuming a level 10 building. How does it compare if you only have, say, 5 Artifacts for it?
Oh absolutely. Honestly, it's the 3 KP that put it over the top. 150% efficiency is great but adding in all of the event buildings that give KP makes a massive long-term difference. I think I'm getting 19 per day in one city having missed a year of prizes and by summer I expect to be making more KP from buildings than hourly.
For some additional math counting the KP, I guess we could use carting libraries as a base? 1 KP per day in 2.5 sq? so 7.5sq value? Over 190% efficiency then.
in my city, it makes Scrolls.
Yeah, that's lame. I'm not sure how to factor that in, I guess it depends on what ratios you are able to dump scrolls at.
I buy up all of the scrolls from my fellows at 1:1 and swap them on the map for a 10% discount without issue so the efficiency of the EBS would drop to 146%, or 187% counting the KP for me. for every 10% discount, you have to give when selling scrolls the efficiency should drop about 3%
If you assign scrolls a value of zero the EBS is still worth 17 squares plus the KP for about 136% efficiency.
Third would be the fact that you can't clear events that ask for specific productions using event buildings. I once got rid of all of my T3 buildings because I didn't need any T3 (I was getting way more than I ever needed from event buildings). But then I had to put one back because a quest asked for a specific production. To give a more specific example, if the quest asks for you to make a Marble Mosaic, you can't complete that if all of your T1 is being supplied by event buildings.
Good points, but as is
1. the EBS can't replace
all of anything, and
2. the events no longer ask for specific productions so a single level 1 factory of any kind can easily satisfy any quest.
3. Since the EBS has a value of close to 36 squares with a footprint of 18 squares that's enough saved space for 7 level 1 factories that you can use to complete event quests.
Finally, if you had invested in certain Wonders like the Mountain Halls, will event building productions gain the same benefits? I haven't done the math as to whether a Mountain Halls and etc. will outweigh the Sleigh.
At level 35 the MtH gives a 284% boost added to the 800% max relic production, an increase of 35%.
Since the goods From EBS account for 54% of the EBS, the value drops to about 115% or 157% counting the KP. Still worth it, but only barely.
A chapter 5 city like
@Eudaemonia 's is still quite a ways from even building a MtHall, and 6 chapters away from unlocking the seeds needed to upgrade past level 30, so I don't think it's too much of a concern.

It's funny, the goods production is everyone's focus for the EBS, but if it gives
4 squares of culture,
4.5 squares of pop,
7.5 squares of KP
1 square of coins (I have no idea what value to assign 90K coins in chapter 5, but 1 seems fair.)
---
17 squares before counting the production at all.
So to rephrase the question:
Can the goods produced replace one of my factories?
Are the goods produced worth more than
one square to me?
