I’m getting tired of hearing it. Anyone who, like me, is strongly committed to more sustainability on the one hand and moderates discussion groups quite frequently on the other, encounters it again and again: this annoying “we have to”. My theory: It’s of no use to anyone. Except perhaps those who say it. But let’s take it one step at a time. Last week, I had the privilege of moderating two rounds at the Expo Real real estate and investor fair. In principle, they went well and were entertaining – at least that was the feedback I received afterwards. And to a large extent I would agree with that. If it weren’t for the unkindness that tends to run rampant at such panels. We have to do more, they say. We have to act faster. We have to do whatever. To make sure that the urgency of the “we must” really gets through, the voice rises, it becomes louder and more insistent. Because we have to. And everyone should finally understand. Who is “we” in …
Without carbon sinks, we will not achieve the climate goals. This was the clear message made in the World Climate Report written by international scientists. By using the right construction methods, buildings have the ability to store carbon in the long term and thus offer major potential. Experts discussed how this can be achieved at the DGNB Annual Congress.
On 22 July 2021, Dr Christine Lemaitre (CEO, DGNB – German Sustainable Building Council) and Prashant Kapoor (Chief Industry Specialist, IFC Climate Business Group, World Bank Group) kicked off the free Master Classes of the Building Sense Now initiative and MISEREOR. Since then, people from 47 countries have participated in the global knowledge exchange on climate-smart building. All past events are available online. One more Master Class will be taking place in February, and more are in the planning.
The new biology and chemistry block at Schubart Grammar School in Aalen – what better place for students and teachers to experience at first hand the interplay between construction excellence and science. Developed by Liebel Architekten BDA in collaboration with Transsolar, the science wing makes groundbreaking use of three environmentally friendly forms of energy: light, thermal energy, and geothermal energy. It’s a pleasant place to learn science. And now it proudly sports a DGNB Climate Positive award.
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.
