At this year’s BAU China, the DGNB returned to the stage of the China Architectural Design Exhibition (CADE) EXPO 2023 in Shanghai. At the DGNB China Community Meeting on 4 August, the network met again for the first time since the start of the pandemic. In addition to many news about the development of the DGNB in Germany, there was a panel discussion on the added value of certified buildings and districts, best practices from China and an outlook on wishes and plans for the German-Chinese collaboration.
As of 2022, all non-residential buildings in Baden-Wuerttemberg that apply for planning permission will be obliged to install photovoltaic (PV) units on a roof area suitable for solar energy systems. This applies to everything from production halls to supermarkets and office buildings. The new requirement was agreed recently by the state government. The DGNB welcomes this move, which it sees as a step in the right direction. All levers now need to be pulled to meet the 2050 climate protection goals. Naturally, this includes the use of solar energy – and there are many more options.
Once a year, the German Taxpayers Federation (BdSt) publishes its ‘Schwarzbuch’ containing examples of what it considers to be wasteful uses of tax revenues by government departments. The current edition names the DGNB certification system as one such example, under the heading of ‘Expensive Image Cultivation’.

In this case at least, it shows that judgement was handed down without understanding the subject in the necessary depth. So here in the blog – with the necessary brevity of the format – we present the most important reasons why certification is actually worth it.
The building and property sectors have been grappling with the topic of building information modelling (BIM) for several years now. But what does BIM mean for manufacturers, architects and planners – not to mention for building operators? Who can afford BIM? And what role does the German Sustainable Building Council (DGNB) play in the discussions surrounding BIM?
