This sounds cool! (Pun intended...)

Is that racist? :p

Painting the exterior of a building with a light color and reflective finish definitely helps.

There used to be a product called Sno Cap that was intended as kind of a mobile home roof coating, except it was very white. I used to paint the tops of old and rusty walk-in freezers with it and it made a considerable difference.

But while it could reduce cooling needs, it would not eliminate the need for air conditioning anywhere that the air temperature gets above desired indoor temp levels.
