Isolate sky from image to make it look like night?

Hi, I'm trying to make the sky in my image look like night however I can't get it to work. I've tried changing the exposure, the colour channels etc but they all change the rest of the image. So how can I just select the sky and modify it? There must be something really simple that I'm missing. Any help would be greatly appreciated.

Here is the image:

This image is probably not the best candidate for Day-2-Night, but I gave it a quick go. The most beneficial tool I used in this manipulation was Blend-If (luminance masking).

Good old selective color, good old brush, good old blend if, good old channel selection?

Yes, there is no "make it look like night" button.

I'd darken the entire image, then retrieve detail where needed and add a bunch of lights and perhaps some smoke/haze.

That's about what I would do too. You have to consider the sources of light. The light in the image is basically coming from indirect sunlight. At night it would be reflections of streetlamps and lit buildings. The first thing I would do is gather reference, then decide where it should originate. It is imo tricky to get a really good result, because it requires both design decisions and technical merit.
