Reflective architectural panels in cold climates.

First post for me in this community (I create it).

So, I invented an architectural concept for cold climate locations that is a reflective facade panel in lower positions of the building. Its objective is to be placed in a position so that the winter sun reflects, somewhat massively, from it, and extend into shadowed space, possibly aligned with time of day for good effect (e.g., speed up warming up space first thing in the morning, once the sun is over the obstacles about), for example, could be positioned within the interior in such a way as to reflect sunlight through the interior and outside also.

The question arises, can I reflect warmth in the sunlight, but filter out UVR (ultraviolet radiation)?

A textured shiny aluminum panel with a thin coating of clear sealant of titanium dioxide. Ensure the coating adheres well to the material and that it is very durable (for longevity, considering that recoating it might be doable)!

Is this specification feasible?

Is there a better material specification to achieve creating this panel?
