You are calculating the energy of the building when it finally reaches the ground.
But during the fall, there is no energy lost. (Correction: There is no surplus energy)
All energy goes into the kinetic energy, the acceleration.
This is what you missed in your calculation. (Clarification: Where you calculate the end-state after the fall)
So when there is a free-fall, there is NO ENERGY to break anything or to push out the pieces of concrete.

Even glass plates that immediately break slow down a fall, stunt people use that principle.
In a demonstration by fake-sceptic megabunk, he shows planks falling down, but forgets two things. The sides that hold up the planks are still standing and the planks still fall down with reduced acceleration.

You need the energy of the dynamics of the fall.
The architects and engineers do know. Just check their website. The link I provided above explains it very clearly, much better than me.

More hints:
The firemen reported explosions and streams of molten steel, after the fire was under control.
The steel bars showed clear traces of extreme heat. These bars were heat-resistant with Molybdenum.
They found little pieces of firemen on top of other buildings, not even body-parts or full bodies.
The fires also kept burning for weeks UNDER WATER, which means that there components of some kind of explosives.
The relative cold dust became so corrosive that it destroyed surfaces of cars and metal parts of buildings far away.
Traces of molten Molybdenum was found on top of the buildings.
The dust contained small iron spheres that only comes from vaporized iron/steel.
Never before and never after has a steel-framed skyscraper fell down due to fire, and there were a lot.

There is a huge amount of evidence for demolitions.
And every box for evidence for demolition can be checked (as FEMA will confirm).
And each point that is brought against it, is usually based on a lack of knowledge.

Just check the Architects and Engineers website.
They explain it a lot better than me.
And if you want to go further in depth, check the scientific studies.

And I am sorry for you that you have been lied to for 19 years and may even have killed people for nothing.

Energy is never lost ya ding dong. Unless you think conservation of energy is a hoax too that is.

All energy goes into the kinetic energy, the acceleration. This is what you missed in your calculation.

Haha, no I did not miss the kinetic energy. Re-read my last reply. It is clearly stated that all gravitational potential energy is converted to kinetic energy during the collapse. I am not sure you have done enough reading on how kinetic energy would be dissipated is such a situation (or in general for that matter).

You need the energy of the dynamics of the fall.

You might be referring to the turbulence of the falling objects. This is typically manifested as a dissipation of rotational kinetic energy as members spin around and bang into each other. Again, I clearly did not miss this.

The architects and engineers do know. Just check their website. The link I provided above explains it very clearly, much better than me.

You did not provide a link. I am sure architects and engineers (again, I am an engineer) could describe this better than you can though.

You need to be more wary of confirmation bias. Everything else you just said is irrelevant or nonsensical.
