The 'problem' with concrete is that it does really, after all this time, require cleaning. And recladding will ruin it. It's a fad and not a good one. The point of brutalism is that it's brut, ie raw.
Fenestration is imortant too. It will need great care if it isn't to alter the character of the building. Not sure tinting is the way to go.
It's there, it ain't going away anytime soon, learn to love it. It's actually a good building of its type, just it's on its own.
