Renovation or Demolition: A Decision with Consequences for Climate, Costs, and Future
Renovate or tear down and build anew? This question not only determines the future of a building but also affects resource consumption, gray energy, and long-term investment costs. The online lecture on November 11, 2026 brings together scientific, practical, and political perspectives and shows how viable decisions are made in existing buildings.
Weighing Between Existing Buildings and New Construction
In Germany, there are around 22 million buildings. A significant amount of gray energy and bound raw materials is contained in their building substance. When a building is demolished, these potentials are lost, while new construction causes additional greenhouse gas emissions. At the same time, the question arises for many properties as to which solution is technically, economically, and climate-politically convincing.
Focusing on Investment Costs and Life Cycle
The lecture looks beyond pure construction costs. It focuses on criteria that systematically compare renovation and new construction. This includes investment costs, life cycle costs, technical lifespan, and the climate impacts of both options. This creates a well-founded basis for owners, municipalities, planners, and all those involved in sustainable construction and real estate development.
Expertise from Science, Practice, and Politics
With insights from Constantin Falter, research associate at the Institute for Infrastructure and Real Estate Management at TU Braunschweig, Elise Pischetsrieder, managing director and architect of weberbrunner pischetsrieder architektur, and Lutz Brinkmann, member of the CDU/CSU parliamentary group and member of the construction committee, the event illuminates the topic from different perspectives.
Panel Discussion and Questions from the Audience
After the insights, a moderated panel discussion will follow. In the subsequent audience phase, participants can direct their questions directly to the speakers. The digital event connects professional classification with practical exchange on sustainable renovation, new building decisions, and future-proof building strategies.
Conclusion: Guidance for a Future-Proof Construction Decision
The event experience takes place online via Zoom and offers compact professional information in a clearly structured conversational atmosphere. Those who want to better understand the complex trade-off between renovation and demolition and learn about perspectives from research, architecture, and politics will receive valuable impulses for their own event planning, project development, or municipal decision-making.
