Architecture and urbanism: Fighting against climate change

Climate change is an urgent issue that demands our attention. Its effects are not only evident in natural habitats but also in urban environments. As we confront this global challenge, the construction industry has a significant role to play in finding sustainable solutions.

What Are Cities Doing to Tackle Climate Change?

In cities, one of the most noticeable consequences of climate change is the increasing frequency of heatwaves that threaten urban populations. Densely populated areas are particularly vulnerable due to the “urban heat island” effect. The risks associated with extreme heat vary across neighborhoods, influenced by factors such as population density, access to cooling systems, and the availability of green spaces.

To combat these challenges, cities are implementing a range of strategies to safeguard their residents. From incorporating green infrastructure and utilizing reflective surfaces for temperature reduction to implementing passive cooling techniques and developing apps to aid safe movement during hot months, innovative solutions are being deployed to mitigate the impact of rising temperatures.

Addressing the Rising Sea Levels

Coastal cities, home to more than 410 million people, face the immediate threat of rising sea levels. These areas, often known for their tourism and maritime industries, tend to prioritize density in their urban planning. Tall buildings and busy roads dominate the landscape, leaving little space for natural buffers.

While governments have traditionally attracted people and businesses to these cities for economic development, their strategies have proven inadequate in countering the impact of natural disasters. Architects and designers are now exploring innovative solutions rooted in nature and local wisdom to restore coastal ecosystems. Initiatives include mangrove reforestation, the construction of breakwaters, and the creation of floating islands offshore.

Unveiling COP27: A Crucial Climate Change Summit

COP27, the 27th United Nations Climate Change Summit, held in Sharm El Sheikh, Egypt, aimed to inspire countries worldwide to take effective action against climate change. The conference focused on maintaining global temperature rise below the critical 1.5°C threshold.

The construction industry, responsible for nearly 40% of global carbon emissions, shoulders a significant responsibility in combating climate change. Governments must enact specific policies to curb emissions generated by the industry. Key challenges include achieving net zero carbon emissions and conducting comprehensive lifetime carbon assessments to understand the industry’s impact. Additionally, promoting climate resilience, especially in vulnerable countries, emerged as a pressing concern during the conference.

Harnessing Building Materials for Sustainable Change

Last year witnessed a surge in interest and research into sustainable alternatives for conventional building materials like brick and concrete. The goal is to reduce the carbon footprint associated with construction.

A notable area of progress is biofacturing, a process that leverages organisms to manufacture materials. Additionally, architects and designers are turning to local materials and traditional crafts to develop a deeper understanding of each country’s unique conditions and involve local communities. These initiatives hold immense potential for combating ecological degradation.

Implementing New Legislation in 2022

Government legislation plays a vital role in ensuring widespread implementation of measures to combat climate change. This year, numerous laws were enacted to create safer and more resilient urban environments. Some regulations focus on the energy consumption of buildings, while others facilitate the transition to renewable energy sources. The overall objective is to establish safe conditions for the public.

New Legislation

In conclusion, architecture and urbanism are powerful tools in our fight against climate change. From understanding how cities are taking action to mitigate climate risks to addressing the challenges posed by rising sea levels, international summits like COP27 are indispensable. By harnessing sustainable building materials and enacting supportive legislation, we can pave the way towards a more resilient and sustainable future.
