The skyscraper is designed to have safety factor of 3-5 times the mass that it has on it, so it could absorb at least 3mgh energy. ...
Truthers never understand physics. If they did, they wouldn't be truthers. This applies particularly to Physics teachers and PhDs like David Chandler, Crockett Grabbe or David Griscom. So you are in good company.
What you write is FALSE. Apples and oranges.
The "safety factor" is for forces - the actual load on structural elements is a force, and they could bear something like 3-5 that load/force without yielding.
Force is not the same as energy. Do you understand that? So it is silly to apply a safety factor for force capacity to some available enegergy.
