Environmental scientists who are constantly working for building up a friendly environment for improvement of human society aim basically at creating a beneficial relationship between the architecture and the natural environment all around us.  Natural elements that surround us have their effects on our lives. Thus, any sustainable designing for building construction needs to critically appreciate the use of these elements in the process of construction. This process is known as BIOTA or Biodynamic Transactional Architecture. Enough information about the technology is available in the Artikeilverzeichnis of BIOTA. 

Green buildings methods that are in use presently are using manufactured products that are green, eco timber and lumber and use of alternative insulation processes. Other processes are use of natural articles accustomed to the local environments like the stone and natural earth and all sorts of non-toxic materials. A Fertighaus that is accordingly designed will be the ideal for keeping in par with the natural environments all around the building. 

For example, you may construct a penthouse on the roof of an existing building that could be used for multifarious purposes. You may build up a panoramic view with a rooftop Garten and if there is a sea or river nearby, it could be a joy to watch.  

For lighting you can use passive elements like a mixture of solar and natural lighting side by side with a green rooftop and a naturkost in the premises of the building.  This will simultaneously address the problems of energy consumption as well as environmental pollution due to harmful emission.
