Attached is an updated Excel spreadsheet program to estimate infiltration in tall buildings. I would like to have comments and suggestions on this issue particularly if the attached views & conclusions are wrong and there are mistakes in the analysis & calculations. Burj Khalifa in Dubai is 828 meters (http://en.wikipedia.org/wiki/Burj_Khalifa ) and the Kingdom Tower in Jeddah is being designed for 1,007 meters (http://en.wikipedia.org/wiki/Kingdom_Tower ).

The input in red (based on %, etc) overrides the entered values for dimensions and CONTAM leakages. Delete them and it will use the leakage info
You can create input files in the Sheet ?Test Input Files?
Highlight the cells in green or section enclosed in red line.
Copy and paste into the next sheet ?Input-Output?
