I was bored recently and worked out some basic analysis of Silverstein's losses. As we know, he has recieved $5 billion in insurance, often used as CT evidence usually tying in with 'pull it'. But I've never seen any CTer factor in the loss of office rental.
He owned leases on the following buildings, and owned WTC7 outright:
WTC7 - 1,868,000sqft
WTC5 – 784,000sqft
WTC4 – 576,000sqft
WTC2 – 4,761,000sqft
WTC1 – 4,761,000sqft
Total: 12,750,000sqft.
I've not found any figures which state how much of the complex was under rent on 9/11, so i'll estimate it was 90%. And i'll estimate an average office rent of $50 per square foot. A little high, possibly, but asking prices for vacant suites at WTC were in that ballpark:

12,750,000sqft x 0.9 = 11,475,000sqft. X $50 =
$573,750,000 loss per year.
Upto 9/11/2006, Silverstein would have lost $573,750,000 x 5 = $2,868,750,000 in office rent.
Add the $600m in rental paid to the PA, and the loss grows to
$3,468,750,000 by September 11th, 2006.
But this can be taken further. The 'Freedom Tower' is now under construction, but not due to finish until 2011, and even then it will be 2.3m sqft which is about 50% the size of one of the twins. The rest of the buildings are due later than that.
At this point, WTC7 is subtracted from the equation since the new one opened in June 2006, though it was only 25% pre-let when it opened, so there will be further losses here, but it is removed to keep things simple.
Subtracting a 90% let WTC7 leaves us with 9,793,800sqft to calculate the loss between 2006-2011.
9,793,800 x $50 = $489,690,000 loss per year.
x 5 = $2,448,450,000 loss.
Add the $630m in rent that would be paid in those 5 years at £138m a year, and we have a total of
$3,078,450,000.
Total ten year loss on office rents: $5,317,200,000
Portion of original lease paid from 2001-2011: $1,230,000,000
It would be interesting to refine these figures with more accurate data for the average office rent price and the amount of space which was occupied on 9/11.
