You can add a bit of insulation inside the concrete to make the house require less cooling than (any?) wooden house.

Concrete insulates quite well by itself. I don't understand the GP's complaint. It can be improved, and there are several improved alternatives on the market since basically forever, but it's not bad by itself, and it's certainly better than wood.

(I really thought it would be about concrete CO2 emissions at first.)
