Sustainable Architecture in Times of Climate Change

Is it as hot for you today as it is for us?
As an architectural firm, this summer weather has prompted us to reflect on the construction challenges of the future. Extreme weather events such as heavy rainfall, heat, and drought are already being felt worldwide. What demands does climate change therefore place on architecture and urban planning?

The current climate debate is prompting politics, clients, and architects to rethink. Awareness is growing that resources are not unlimited. This is fostering ecological consciousness and encouraging interdisciplinary thinking and action to develop new and optimal solutions for the sustainable and energy-efficient architecture of the future. How, then, can we create architecture that benefits both people and the environment without relying on complex technology?

Learning from Local and Traditional Architecture
The starting point for any new design is always the site. It is influenced by geographic and climatic conditions. Sustainable and energy-efficient architecture must therefore orient itself to and adapt to the topographic, climatic, and cultural conditions of its surroundings. Collective regional knowledge provides solutions tailored to local circumstances. This approach enables the construction of low-tech buildings with natural shading and ventilation that adapt to the climate and respond to extreme weather.

Existing Buildings and New Constructions
Before erecting new buildings, it should always be evaluated whether existing structures can be future-proofed through renovation and climate adaptation. For example, in our Project in Frankfurt am Main we carried out the energy-efficient renovation of a former men’s dormitory into a modern residential complex with small-scale apartments as a KfW Efficiency House 70. Many municipalities provide funding for such upgrades (e.g., funding programs from the city Düsseldorf).

Individual and varied adaptations in existing buildings and new constructions can include:

• Green façades for cooling, reducing heat buildup, serving as retention areas, and creating a microclimate
• Development of a holistic energy concept with renewable energies
• Low-tech rather than high-tech solutions for energy-efficient buildings
• Use of building materials and furnishings that are biologically harmless
• Minimal soil sealing on the property
• Building shading (greenery, sun sails) to generate cooling
• Planting future trees (Quelle: Stadt Düsseldorf)
• Unsealing open spaces

The sum of these individual measures forms a comprehensive matrix for sustainable, climate-conscious building development.

For our shared future, it is therefore crucial how we use, renovate, or construct buildings, and with what standards we approach these tasks. Architecture has the power to respond to climate change by designing with both people and the environment in mind. It is essential to focus not on short-term goals but on long-term sustainability.
