Glass + HDR?

What do you use for internal Arch Viz for lighting / window material combinations? I want to use the glass shader and an HDR environment map, but it seems like refraction is not possible with HDR environment lighting.

What are the options to resolve this? Adding a transparent and glossy shader will allow me to use the HDR image for lighting, but I can’t seem to control the reflections as well as I would like (advice?).

Using mesh lights in the windows is another alternative, but much of the external world is visible in the model, so the mesh lights don’t really look right.

Is there a generally accepted solution to getting decent looking windows whilst using an HDR environment map for lighting?

Thanks,

Matt

Any ideas?
