Challenges of climate change in new construction

Climate protection and climate adaptation are the two major levers for meeting the challenges of climate change. In new buildings, these aspects can already be considered in the planning phase, but what about existing buildings? How much "grey energy" is in an existing building? And can renewable energies also be used as urban design elements? How extensively must sustainability be thought of in the built environment? An interdisciplinary cooperation between the Master's course "Project Material & Ecology" led by Prof. Michaela Hoppe and Prof. Ingo Lütkemeyer and a project group from the ZEUS Master's programme led by Prof. Dr. Jürgen Knies explored these and other questions in the winter semester 21/22.

Case study residential and commercial building, Gröpelinger Heerstraße No. 199

Using the example of the residential and commercial building at Gröpelinger Heerstraße No. 199, architectural, urban planning but also socio-economic initial conditions were examined. Initially, all stakeholders were challenged to develop a common understanding of the challenges. During workshops and site visits, the different perspectives became clear and it was gradually worked out where synergies existed.

In addition, the students entered into an intensive exchange with the homeowner and were able to pick up on the urban planning framework conditions and ongoing programmes first-hand from employees of the Senator for Climate Protection, Environment, Mobility, Urban Development and Housing (SKUMS).

Cooperation project between architects, environmental and energy engineers

The ZEUS students took on the role of "consulting engineers" in the cooperation project and provided advice and assistance to the architecture students. In the architectural designs, for example, PV modules on the roof and façade were considered as design elements in various forms and evaluated with regard to energy and climate assessment.

As a result, the designs by Olivia Gieger and Filip Kowalik were analysed in more detail and an energy concept was developed for each. With the help of a reference concept, the theoretical overall potential could be determined. Furthermore, the question of how sustainability can be measured in its entire range and used as a basis for decision-making was explored.

Students' quote:

"The exchange with the ZEUS students led me to adapt my design with regard to the building technology, which resulted in a perfect interplay of architectural language and building technology. The collaboration showed that the exchange of different disciplines is the basis for optimally adapting existing buildings for the future and the climate requirements that come along with it." Olivia Gieger, Architecture / Environmental Design

"The collaboration of two parties on the sustainable design of a real building illustrated the necessity of interdisciplinary knowledge and possibilities for the success of such a large-scale project. Despite, or perhaps because of, some difficulties, all participants were certainly able to gain important experience for their professional lives in the near future." Marius Kalmbacher, ZEUS

"The cooperation with the architecture students was very enriching and could give us as future engineers an idea of real projects including the hurdles and problems. I hope that the building will be renovated in the near future, because the visions of the concepts are promising." Pia Niebel, ZEUS
