For architects, working on existing buildings can be exciting, but it can also be quite challenging. Apart from technical imponderables, it’s important to ensure ideas brought to the table work in harmony with things already in place. Reichel Architects have succeeded in bringing buildings owned by the Evangelical Bank in Kassel in tune with modern times – not only in terms of design, but also when it comes to energy use.
Sustainable construction is booming in Germany. So how are things going for our neighbours? How is sustainable building faring in other European countries and where does Germany stand in comparison? DGNB CEO Dr Christine Lemaitre seized the opportunity offered by our 2022 annual congress to exchange notes with our friends and partners working for the Green Building Council in other European countries.
In Germany, the community of volunteer firefighters plays a key role in dealing with fires, floods and other major incidents. Recently, a new working facility was built for the special community of volunteers in the Hessian town of Caldern. Now, when an emergency call comes in, the firefighters burst out of a sustainable building that is even the proud owner of a DGNB Gold Certificate. It’s also worth mentioning that it was the first time in the history of the DGNB that a firefighting organisation has been through the certification process.
Established office setups have been shaken from top to bottom since coronavirus arrived nearly two years ago. In response, more flexible working arrangements have been required. At Axel Springer, a change in thinking was already underway before the pandemic. In 2013, an architecture project was put out to tender for a new building offering ultimate flexibility in terms of work structures. The new Axel Springer building entered use in 2020 and is now open for business to more than 3000 employees. As well as receiving DGNB certification in gold for high standards of sustainability in new construction, the building also received DGNB certification in diamond to underscore its high architectural quality.
As well as shaping our environment, buildings preserve the memory of times long past. Achieving climate targets also means it’s important to look after existing buildings, as was the case in Berlin recently with the refurbishment of a residential building more than 130 years old. The project has underscored that it is possible to carry out renovations in keeping with preservation orders and sustainability needs.
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.
