I am not sure the laws of thermodynamics (1) would allow to use that heat to cool a building. You would need a cold source like a river to convert heat back into electricity. But it might be more cost efficient to have the water from the river circulate directly into the building, so that your extra heat is still remaining unused.
This is why I think it is more difficult to find solutions in a hot country like Florida than in a cold country (as long as you don't question the very existence of heated homes in cold countries, leaving aside the possibility of moving people and their homes from cold to warm countries).
