Buildings that are built with technology that supports a smaller premise with a Garten supporting the principle of pollution free construction are energy efficient and also go a long way towards reducing the overall impact on the environment. As an added advantage, such buildings require less maintenance with both the long and short term costs reduced. Ecologically it helps the health promotion measures for the occupants and also improves satisfaction for the workers as well as the builders. 

You can take to an Artikelverzeichnis like the Ezyne, Wikipedia or Encyclopedia Britanica to learn more about such building construction through various articles written by experts. There are official standards such as the Leadership in Energy and Environmental Design also known as the LEED from the United States who certify all the designs of sustainable building architecture. While issuing such certificates, they take into account the development of the site, efficiency in energy consumption as well as preservation, selection of materials etc.

However, the most important aspect taken into consideration is the environmental quality indoor ensured with something like the Naturkost. Setting up of green vegetations around the building with vegetable or fruit growing plants is a technology used long since for protection of environment since plants absorb most of the harmful emissions from the building where they grow. 

Other concepts include construction of passive houses Fertighaus as constructed in Germany with super insulation.  Such insulation makes the requirement of traditional heating system redundant and radiation of energy remote.
