If you look at the major building certification systems that are currently leading the way in Europe, you can say that it is the Breeam label introduced back in 1990, followed by Leed in 2000, founded in Germany in 2008 then here in Stuttgart the DGNB, German Sustainable Building Council. Development continued in 2012 Active House, 2014 Well Building Standard, 2014 Active Plus.

Even with the time intervals alone, you can see that the various awards for entire buildings in recent years, the times in which new labels came onto the market are becoming ever tighter, suggests that the quantity here is increasing rather than getting smaller. I regard this as still a big advantage right now, because all these different labels have different concepts, how do they certify buildings accordingly? Which aspects play a role in this?

And they show to a certain extent how great the variety is, much more than just green. Once it starts with the transport route, the energy it contains, goes into concepts that are all considered here at these major labels.
