What Orchid can I grow in a south facing window?

What kind of window do you have?
Is it a modern three layerd isolated energy glass or an old normal glass window with one or two layer of glass, or something else?
The window will filter the light and depending on what window you have the light will be more or less harmfull.

Pavel´s queation on the temperature in the window is also relevant. If you have "old" windows there can be a significant lover temperature on the widowsill than in the room.

It’s a newly build house so the windows are very well insulated and energy efficient. The window is very big and covers an area of 8 by 8 ft. The temp right by the window is about 2-5 F higher with the sun than the room temperature. I have a small coffee table of phals currently doing well with indirect lighting in this area.

I also have two small south facing windows on the second floor where I keep my other houseplants that have been growing really well. On the window facing the plants, I have applied an opaque glass adhesive to filter the lights and the other window overlooking the stairs has no covering. This area is hot compared to the rest of the house. Daytime it’s about 78 F vs the rest of the house is at 72 F.

Thanks for the advise.
