On this view from the window I want to make air a bit dusty.
This I rendered with box with volume. It works pretty well, except it also dims the hdri, which is not needed. And it is very slow.

If I remove the glass from windows I can save depth like this, but then I don't know how to mix it with actual image.
What do I do?

If I understand you correctly, you want to do a composite using depth pass to add fog to the environment?
Basically you use it to mask out white layer added on top

I want to mix in compositor image with some color, based on depth, where further object would be more mixed. The most black and white areas be totaly unaffected. I can't come up with node setup.

Something like this?
You might have to adjust the value circled in red.

Is it bad to wish something horrible would happen to people, if they coded blender compositing?

Thank you, but maybe I no longer want to to anything with blunder compositing.

I like this new window composition very much (again)!
Especially how the Ferris wheel is hidden: It makes me shift my head - then laugh about myself

(Sorry to be of no help with the blending but here's no compo skills.)

There's more! It is animated. I managed to get (more or less) desired result rendering image with and without dusty volume, then mixing it with alpha in gimp. I wish there was simpler way, like checking checkbox and moving the slider though. Also I want to say that he who model buildings should look to it that the building will have single surface, strictly dividing space into inner and outer. Then you can add bevel to corners and displace to whole building, so it wouldn't break anything.
I didn't and now have to weld everything together.

The outside scenery is most interesting and seeing it animated would be awesome!
