The insulation is the easiest to add to old buildings.

Red bricks offer better thermal insulation than dense standard concrete. Because of their porous clay structure, red bricks absorb heat slowly during the day and release it at night.

Solid concrete blocks, conversely, are highly conductive and absorb/transfer heat much faster, usually requiring added insulation.

We could just fix the insulation where it is bad instead of tear down the entire housing unit and rebuild it with concrete / glass / metal.
