German quality seal
Sustainable building
● The basic version was jointly developed
for offi ce and administration
buildings by the German Sustainable
Building Council (DGNB) and
the Federal Ministry of Transport,
Building and Urban Development
in 2009. A retail construction version
was developed in the same year
● Unlike LEED and BREEAM, the
DGNB certifi cate is not a green label,
but a general system that assesses all
aspects of sustainability
● It primarily uses quantitative
evaluation methods. For example,
it calculates and assesses life cycle
costs based on a life cycle analysis
● The certifi cate is awarded based
on the degree of fulfi llment: bronze
(> 50 %), silver (> 65 %), gold (> 80 %)
