It could be. A well insulated home requires cooling of some sort to stay cool or it will heat up, as it contains heat sources and is well insulated. That gets harder as the outside temperature rises. This has nothing to do with the colour of the building, though. And it's not something you can ease by removing the insulation – that actually makes it worse as now the high outside temperature might just make the inside temperature even higher.

Insulation resists heat transfer in both directions. Extremely well insulated and air sealed homes resist heating up just as much as they resist cooling off.
Windows are a bit special in that you can get solar gain through them, but modern windows can have coatings that filter UV and IR from entering a building.
People and electronics are heat sources inside a home, but pretty minimal ones. Any reasonably speced ventilation system a modern home needs to exchange outside air will easily handle keeping a modern house cool.

Most UV and IR doesn't actually need any real coatings. Glass just isn't transparent to that light, completely by itself. It's actually specifically the imperfections in said glass which cut out the most dangerous part of UV radiation, and it's the inherent temperature which messes with IR.
