New views Suggestions on how to improve daylighting conditions in a shaded buildings.

I am going to share with you one of direction a topic of my Phd. dissertation.

Why does one building obscure another from sunlight and why does the problem appear? In Russia it is a problem, due to a little amount few of days of sunshine.
Well, Before construction, the construction site looks like a flat surface. However after finishing, it becomes a quite big volumetric prism or figure filled space, which take away blocks most of the much sunlight, that was supposed to be allocated on to other sites or buildings as well.
How can we solve this problem?
Let's switch on use our imagination.
There are at least two ways - we can use a sunlight guide to transport sun solar radiation through the first building or we can reflect excess solar radiation from superheated facades to shaded sites.

Nevertheless, there are some questions:
-properties of reflected sunlight (is it equal with direct sun radiation);
-attitude of inhabitants toward the reflected sunlight;
-brightness;
-excess IR-radiation of sunlight (warm part of sunlight);
