Case Study 1 in the demonstration exam
Anyone know please the new gross square feet question 5?
How to come to 92,610? I calculated several times and can't seem to get this number.
Thank you

Yvette,
I am trying to figure this out too.
Based on following information, we can calculate the Net Square feet to be reduced from program. To convert NSF to GSF we use the efficiency factor of 1.4.

Each Concessions/Retail space must be reduced by 10%.
This results in 200 NSF reduction in Concession /Retail Space
Convert to GSF = 200* 1.4 = 280 GSF reduction

The seating capacity of the Main Event Space will decrease to 4,000, reducing the square footage by 15%.
Reducing area by 15%:
40,000* .15 = 6000 NSF > 6000*1.4 = 8,400 GSF
The building efficiency factor will decrease to 1.4.
Since Exterior plaza is outdoors, I am assuming it is not included in GSF calculation.
Finally, Total GSF Reductions in areas calculated above:
108,525  (8400+280) = 99,845
But this is not the right answer. Can anyone help with this.


So this is what I did and I don't know how am I going to have time to do this on the real test, I hope NCARB would explain if there is an easier or quicker steps to this:
I added each NSF from the resource except the exterior plaza because like you said it is "exterior"
and reduced the
The main even space = 40,000 x 85% = 34,000 NSF
Retail = 2000 NSF x 90% = 1800 NSF
so the total came to 66,150 NSF x the new 1.4 "building efficiency factor" = 92,610 GSF

Sounds like the type of question you should just SKIP on the real exam. If it requires more than 3 mathematical steps, I say forget it...! Especially if you have to hunt around inside case study docs to find the pertinent info too. Use the time to answer 3 other questions correctly!
Hope this helps!

In response to Yvette A quicker way would be to subtract the NSF of the two spaces from the total NSF given then add the new NSF of the two spaces to the number you originally subtracted from.
72530 NSF  40,000 NSF  2000 NSF = 32350 NSF
Add the new NSF of the spaces to 32350 NSF to get the new total NSF
Does that make sense? I'm terrible at explanations
