Is solar energy technology considered to be in this category and also what is the history behind this new technology.
Examples of recycled building materials are:
Bricks cleaned up and re-used
Roof Tiles
Windows (sometimes if they have good thermal insulation)
All concrete and stone items are frequently ground up on site and then added to cement and sand mixes to replace aggegate (used as foundations)
Old floor boards can be sanded and polished up to be re-used.
Solar panels are usually manufactured from silicon based parts with plastic overlays etc. I have never heard of these materials coming from recycled building items. I guess that you might mount a solar panel on the roof of a house with old wooden beams from a roof or floor?
Solar panels have been known about for many years but their efficiency has been very poor and the cost of construction is so far greater than annual energy savings that they were generally not worth having. Over the last 5 years however there have been some major advances using exotic chemicals which allow solar panels to be just about viable in hot countries with most days having full sunshine. If the cost of manufacture continues to drop then they are going to become more and more viable..
If your idea of using recycled building materials becomes reality then this will help to spread the technology even further. At this moment I still can not see how to use recycled materials though.
Recycled building materials are building materials that have been recycled.
<<Is solar energy technology considered to be in this category…>>
No, as you don’t make buildings from solar energy technology.

No solar energy is not. Solar is a renewable energy. Recycled building material is something that was used previously and then converted into usable product again.
