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.
Any conversation about climate protection and introducing key measures likely to make a real difference quickly moves on to the topic of buildings. Our choices regarding how buildings are planned, constructed and used have a considerable impact on the carbon levels of our planet, which are currently somewhat worrying. But there’s also good news. We can turn things around and make positive contributions to climate protection in the way we need to – but only if we work together, approach things systematically and act as quickly as possible. How specifically this should happen is addressed by a number of services recently announced by the DGNB.
All existing buildings in use in Germany must be carbon-neutral by 2050. This is truly a Herculean task for the entire construction and real estate industry. For building owners, users and real-estate portfolio owners, this means their CO2 balance at the end of the year for ongoing building operations must be zero. For this to succeed, a targeted, holistic and, at the same time, building-specific approach to sustainable optimisation is needed. The system’s solution here is simple.
You can erect and use a building without having any negative impact on the environment. Really? Is that possible? Yes, it certainly is. Even today. For the first time, the DGNB bestowed its new Climate Positive award on eleven projects at the Expo Real 2019 trade show. We spoke to the designers, architects and users of the award-winning buildings.
