Climate change poses enormous challenges for cities and municipalities. Urban neighborhoods in particular are especially vulnerable to the effects of climate change such as heat waves, heavy rainfall and flooding due to their dense development and high population concentration. In order to meet these challenges, the concept of resilient neighborhoods is becoming increasingly important. Resilient neighborhoods are able to adapt to changing climatic conditions, mitigate extreme weather events and maintain the quality of life of their residents even under changing environmental conditions.

Climate change poses enormous challenges for cities and municipalities. Urban neighborhoods in particular are especially vulnerable to the effects of climate change such as heat waves, heavy rainfall and flooding due to their dense development and high population concentration. In order to meet these challenges, the concept of resilient neighborhoods is becoming increasingly important. Resilient neighborhoods are able to adapt to changing climatic conditions, cushion extreme weather events and maintain the quality of life of their residents even under changing environmental conditions.

The development of resilient neighborhoods requires a holistic approach that integrates urban planning, ecological, social and technological aspects. Key elements include the adaptation of building structures, the creation of green and blue infrastructures and the promotion of social networks and local communities. Only through the interplay of these different factors can neighborhoods be made resistant to the diverse effects of climate change.

Climate-adapted architecture is a key component of resilient neighborhoods. Buildings must be designed in such a way that they can withstand both extreme heat and heavy rainfall. This includes passive cooling concepts such as optimized building orientation, shading elements and natural ventilation systems. At the same time, buildings need to be protected from flooding, for example through raised first floors or waterproof basement constructions. The use of light-colored, reflective materials for roofs and facades can also reduce the urban heat island effect.

Green and blue infrastructures play a central role in adapting to climate change. Green spaces, urban trees and green roofs not only help to improve the microclimate by providing shade and regulating humidity, but also act as natural water reservoirs during heavy rainfall. Urban forests and parks act as the “green lungs” of the city and can lower the temperature in their surroundings by several degrees.

Blue infrastructures such as water surfaces, retention basins and open water systems play an equally important role. They can absorb and store rainwater to prevent flooding and at the same time serve as a water reservoir during dry periods. Innovative concepts such as “sponge cities” aim to store and use rainwater decentrally instead of draining it away quickly. This not only relieves the burden on the sewage system during heavy rainfall, but also improves the urban climate during hot spells through evaporative cooling.

In addition to structural and ecological measures, strengthening social structures is a key aspect of resilient neighborhoods. Strong neighborhoods and local networks can provide quick and effective help in crisis situations such as heat waves or flooding. Community gardens, public meeting spaces and local initiatives promote social cohesion and enable residents to prepare for the challenges of climate change together.

Education and information services play an important role here. Residents must be informed about the risks of climate change and possible adaptation strategies. Participatory planning processes in which citizens are involved in the design of their neighbourhood not only increase acceptance of adaptation measures, but also mobilize local knowledge and resources.

Modern technologies can make a significant contribution to the climate resilience of neighborhoods. Smart city concepts make it possible to record and analyze environmental data in real time in order to be able to react to extreme weather events at an early stage. Intelligent irrigation systems optimize water consumption in green spaces, while smart energy networks can ensure the local energy supply even in crisis situations.

Innovative materials such as cooling road surfaces or self-cleaning façades that break down air pollutants also contribute to improving the urban climate. 3D city models and climate simulations help planners to predict and optimize the effects of adaptation measures.

The implementation of resilient neighborhood concepts faces various challenges. Financial resources, legal frameworks and existing building structures can make adaptation measures more difficult. In addition, the complexity of the topic requires close cooperation between various stakeholders from the fields of urban planning, architecture, environmental sciences and social services.

Nevertheless, the development of resilient neighborhoods offers enormous opportunities. In addition to improved climate protection, they can significantly improve the quality of life of residents, reduce energy costs and open up new economic opportunities. Pilot projects in various cities around the world are already demonstrating how resilient neighborhood development can be successfully implemented.

The future of urban development lies in the creation of adaptive, multifunctional spaces that can react flexibly to changing environmental conditions. Resilient neighborhoods are not just a response to climate change, but a model for sustainable, liveable cities of the future. By investing in the resilience of our neighborhoods today, we are creating the basis for healthy, resilient and future-proof urban living spaces.

As the population increases, so does the density stress in Swiss cities and conurbations. At the same time, outdoor recreation and sport are becoming more important. A 2014 publication on the greater Zurich area provides examples of how existing green spaces can be made more accessible. Pieter Poldervaart analyzes the results in the December issue of G+L. You can download the Freiraumnetz Zürich study here.

8.42 million people lived in Switzerland in 2017, compared to 7.08 million or 19 percent fewer twenty years ago. In the past, this annual growth of one percent and the increasing demand for living space per capita was accompanied by a partly unchecked urban sprawl. Greater Zurich is particularly affected by the rapid growth in the resident population. Three million people live in the perimeter defined as the Zurich metropolitan area, which includes not only the canton of Zurich but also numerous municipalities in neighboring cantons and even in neighboring southern Germany.

Forecasts suggest that 30,000 people per year will continue to move to Switzerland’s economic center. In addition to housing and jobs, these people also need recreational space. In 2014, the Zurich Metropolitan Area Association therefore published an outline that shows the way to a “settlement-related open space network” – as the title suggests. In addition to describing the problem, the guide aims to show how existing recreational areas can be upgraded and new ones created and how planning is possible across municipal and cantonal boundaries.

German Brick Award 2019 presented – one prize, many awards for exemplary energy projects

The results of the German Brick Award 2019 were announced on February 1: 120 submissions of exemplary energy-efficient brick projects from all over Germany made the decision difficult for the jury, chaired by Piero Bruno from the Berlin office of Bruno Fioretti Marquez. The high design quality ultimately led to a large number of awards – two main prizes, six special prizes in various categories and eight commendations.

The main prize for monolithic construction was deservedly awarded to Harris + Kurrle Architekten from Stuttgart for the municipal library in Rottenburg am Neckar. The jury praised “the sensitive positioning of the remarkable new building as a communicative and contemplative place in the fabric of the city”. It also praised the public building for its skillful, creative use of monolithic exterior wall constructions made of highly insulating bricks.

An extension

The main prize for multi-shell construction went to the remarkable extension to the Philosophy Department of the University of Münster by Peter Böhm Architekten from Cologne. “The building, modestly described as a ‘shelf wall’, cleverly incorporates the existing listed building and forms an attractive façade opposite the historic Fürstenberghaus,” said the jury. “In this case, the haptic brick becomes synonymous with sensual appeal and a cleverly reduced, ornamental appearance.”

A special prize for energy efficiency

Several special prizes were also awarded, including one for “Cost-effective, energy-efficient multi-storey residential construction”. This was won by the Ulm-based firm Braunger Wörtz Architekten with their project at Vorwerkstrasse 23/1 in Neu-Ulm. The new building for the Neu-Ulm housing association (NUWOG) comprises 31 publicly subsidized, barrier-free rental apartments in a six-storey building and is designed as a KfW Efficiency House 70. The jury: “The uncomplicated design with monolithic brick exterior walls, which are finished with a white cement scratch coat that does not require painting, guarantees this residential building a low-maintenance, long life.”
