Although there is a Glass Window material on the windows they looked just black without reflections of the environment Hdr image, as you can see in the attached image.
I see a reflection in the 1st floor glass. Maybe your HDR has a lot of black on that side. Try a stock outdoor HDR to see if it makes a difference.

I tried a lot of HDR images, but I have not seen any improvement. Maybe someone can upload an HDR image which solve this problem.
You may want to enable the "Product" Lighting preset. This ensures that you have Global Illumination enabled, as well as a higher ray bounce value.

As you can see in the attached screenshot there is already GI and a lot of raybounces.

Finally I found an HDR image that causes reflections. This appears to be a serious challenge.

There's another trick, but it may be difficult with an arch model.
Bring in a vertical plane. Apply a JPEG of your choice. Move it around until the JPEG reflects in the glass.
Of course the plane has to be just out of the camera sight lines.

Thank you. But there should be a way to make the plane with the image to be invisible, and to affect only the reflections on the windows, and without shadows.
Use the emissive material and leave the intensity at 1.
Thanks for sending your file. I just checked it out and see that you're using the default environment, which will not reflect a sky. Are you confusing the backplate and environment perhaps?
Try this:
- Go to the Library>Environment tab and under the Outdoor folder, drag and drop in one of those (to reflect a sky)
- Now, go to the Project>Environment tab, adjust the size and height slider to taste
Also, if you want the glass to reflect the environment a bit more, adjust the window's (glass material) refraction index to a higher value.
Here's my result:
