Rapid urbanisation across the globe has seen development plans for whole new cities on the rise, but is there truly a need for them?

Humanity has built new cities throughout history. Some emerged organically to support trade networks, some as defensive strongholds, and others as the realised dream of a modernising monarch or a unifying political leader. In the modern, post-Second World War era, hundreds of deliberately planned new cities have been built or are currently in development. The number of new city projects has exploded in the past two decades – but why?

The world is undergoing its final wave of urbanisation

While most of the high-income world is already about as urbanised as it will likely ever be, with any future charges being marginal, low and middle-income countries are undergoing an urban explosion. IndiaChina and Nigeria alone are expected to add 416 million, 255 million, and 189 million new urban residents, respectfully, by 2050. Nearly all the most rapidly urbanising countries in the world today are located in sub-Saharan Africa, and this region will be home to the world’s leading megacities by the end of the century, surpassing Asia.

But as these countries approach 40%, 50,% or 60% urbanisation, they’re doing so at significantly lower levels of income and with significantly less state capacity than, for example, the US in the 1920s or South Korea in the 1970s.

So as cities throughout sub-Saharan Africa, South Asia and elsewhere undergo extremely rapid urban growth, their economies are proving incapable of productively employing a growing, and very young, workforce and their governments are proving incapable of building sufficient infrastructure or providing sufficient public services. These are deeply challenging problems of political economy to solve. New cities are offering a valuable, albeit incomplete, solution.

Building a new city on the outskirts of Lagos or New Delhi doesn’t solve their respective problems overnight. However, it does help meet the overwhelming public demand for new urban spaces and the economic opportunity those spaces are expected to provide. New cities, which are often endowed with some form of special economic zone status, and are targeted towards specific industries, can become new hubs that are far more attractive to potential investors and entrepreneurs, with better policy regimes and infrastructure support, than existing cities.

Retrofitting existing infrastructure can be several times more expensive than building new infrastructure – getting the bones of a city “right” in advance of settlement is helping to address the economic and humanitarian challenges faced by millions of urban dwellers.

For many urbanites worldwide, physical environment limits their economic potential and quality of life

It’s hard to be a remote-working software developer in Nigeria if the internet and electricity are frequently out of service. It’s hard to raise a family in a city where there are no sidewalks or public safety is a major concern. Cities generate economic progress and new ideas by attracting lots of people to a single location, the creation of agglomeration economies.

New city projects like Itana, outside Lagos, or Silicon Zanzibar, are rebuilding these talent networks in new, more attractive, and more productive locations. New cities like Ciudad Morazán, Honduras, or Small Farm Cities Malawi are offering the average family in poor countries quality housing they can actually afford, good jobs, and safe, vibrant communities.

Industrial-scale new cities like Enyimba Economic City, Nigeria, and Gu’an New Industry City, China, are creating the physical and policy environments needed to generate real economic progress, which is not always easily replicated in existing cities.

The history of building new cities

Beyond the economic factors driving the creation of new cities, it’s undeniable that building new cities is an inherently interesting, exciting venture. In the history of new cities, this energy has manifested itself with incredible results, such as St. Petersburg, Peter the Great’s Russian gateway to the west. However, at other times, there are new cities that prove to be nothing more than white elephants that waste valuable public revenues or private capital.

It’s great that Brasilia looks like a bird or an aircraft when viewed from above, but whether Brasilia works for those relegated beyond the city’s wings is a more important question. Is Akon’s proposed city with its eponymous cryptocurrency really the right project to accelerate Senegal’s development? How many times are we going to hear about new smart cities being just around the corner in India?

For some new cities, it’s simply too early to render an honest judgment. Saudi Arabia’s Neom project has attracted throngs of admirers and detractors for its unique 170km straight-line urban plan. It could be a bust, like its predecessor King Abdullah Economic City, or it might very well introduce new dynamism to the Saudi economy and even some liberalism to Saudi society. And we shouldn’t forget China’s famous “subway to nowhere,” where just a few short years after this rail expansion was roundly mocked, it became a subway to somewhere.

Humans have always built new cities and have done so for an endless list of reasons

Today’s new city builders are no different, with visions ranging from boosting innovation to unlocking the economic potential for the poor to cementing political or cultural legacies to combatting the effects of climate change and raising sea levels. New cities are “having a moment” as builders and policymakers scramble to answer the immense challenges and opportunities posed by urbanisation at a pace and on a scale never seen before.

The New Cities Map was built by Charter Cities Institute to address these challenges and provide data-driven answers. The open-source database catalogued every contemporary new city built since 1945, recording their development structure, finances, history, and governance. By looking backwards at unprecedented quantitative data, researchers and policymakers will have a greater ability to comprehend what makes a new city succeed or fail.

With the trend of new cities appearing everywhere unlikely to subside, it’s in the global interest to understand how to get them right.

How AI physics has the potential to revolutionise product design

How AI physics has the potential to revolutionise product design

This article was published by the World Economic Forum on 26 June 2023.
Joris PoortFounder and Chief Executive Officer, Rescale

  • Artificial Intelligence (AI) tools like ChatGPT have become mainstream, but the use of AI in the product design process is less widely known.
  • Engineering and scientific computing are harnessing AI to define a new era of innovation across industries.
  • Computer simulations are increasingly using AI to understand how different product designs will perform.

 

The impact of Artificial Intelligence (AI) on digital services is quickly becoming apparent. Tools like ChatGPTBard, and GitHub Copilot are transforming how we work and live.

What is less known is the potential for AI to revolutionise the basic nature of research, engineering, and physical product design.

Engineering and scientific computing is now the foundation of innovation. These methods often require massive computing power from supercomputing clusters (also known as high-performance computing or HPC) to run detailed simulation models that replicate the real world.

Across industries, research and development (R&D) teams use digital simulations to explore the physical world effectively. Use cases vary from inventing life-saving medicine, improving aircraft design and pioneering sustainable energy to creating self-driving vehicles, and refining manufacturing processes, among many other possibilities.

Now, AI offers the potential to supercharge engineering and scientific computing and transform how organizations innovate.

Making R&D more efficient

The computer simulations used today for engineering and scientific computing are increasingly benefiting with additional assistance from AI (and in some cases replaced by AI), dramatically lowering costs and helping engineers find the best answers faster.

Running simulations can be expensive, often requiring supercomputers to crunch massive data sets and execute highly complex calculations. But if you can build a machine learning (ML) model on how the physics works, you don’t need to run simulations every time since your ML inference model can extrapolate the answer from the data.

This means you get the answers on how a particular design will perform faster and cheaper. Over the long term, machine learning, physics-informed neural networks, and other AI-based tools will become standard tools for all engineers and scientists to maximize productivity within R&D development.

The era of AI-assisted engineering

Organizations that become adept at creating well-crafted AI-physics models will gain a solid competitive advantage. Such capabilities will help them establish a fundamental physics understanding of how different product designs will perform in real life. This has huge implications for how organizations retain knowledge in their research and product development.

AI-physics models can capture best practices knowledge about how physical objects behave – information that traditionally has been in the head of an expert, such as a scientist, engineer, or designer.

An aircraft engineer, for example, has accumulated knowledge about the best design approaches for the shape of wings, which then informs their choices regarding the types of design options they explore with digital simulations.

But that kind of information can now be captured with AI, which can then come up with a shortlist of design suggestions that engineers can then further explore with digital simulations.

Critically, suppose a company can create an ML model of best practices for wing designs (by training the AI tool on its body of knowledge about airplane wings). In that case, it can retain that expertise, regardless of if an engineer leaves the company.

This also brings far greater agility to an organization. If a company wants to build a new kind of plane that is more stable in high winds, an ML application can quickly generate the best options for the shape of the wings, helping the organization rapidly spin up new prototypes to enter new markets.

AI will physically shape our world

Given AI’s ability to help us understand the physical world, we are likely to see new shapes in all types of products, from buildings and aircraft to furniture and automobiles. Such innovations are being driven by another variant of AI: generative design.

Generative design works much like generative AI for writing text. By providing some basic guidance (prompts) about what you are trying to design, generative design tools will output many possible options, some of which you would not have thought up on your own.

By letting the software decide the design based on your performance objectives, some fascinating possibilities can result. Generative design, for example, is creating prototypes with a very biological look.

Navigating the AI transition for science and engineering

Organizations that embrace AI will accelerate engineering and scientific discovery while developing innovative new solutions that would be computationally prohibitive using traditional approaches.

Despite the promise of AI, organizations across industries will need to establish engineering and research best practices to help ensure they navigate this transition safely to maximize the benefits to society without needless risk.

Most importantly, AI is only as good as the information it trains on. Organizations will still need to do much work to provide the essential information to make the AI tool smart in the right ways.

Also, legal issues for AI are still very much undefined. Organizations must carefully review the outputs of AI to ensure accuracy, as well as watching for any ethical red flags.

Security is also another important consideration to make sure AI practices don’t accidentally expose intellectual property or proprietary information.

Certainly, guardrails for how organizations use AI are essential as we work through the early days of this new technology. But with some thoughtful measures in place, AI can safely open up all new possibilities for research and development, helping organizations move faster, become more agile, and discover better ways to invent the future.

Supporting the adoption of AI physics will help us make better products faster, accelerate the R&D innovation process, and explore the boundaries of knowledge to develop new engineering breakthroughs and scientific discoveries.

Exploring the Intersection of AI and Sustainable Architecture

AI and the Built Environment: The Next Generation of Design Solutions

Exploring the Intersection of AI and Sustainable Architecture

Artificial intelligence (AI) has been making waves in various industries, and it’s no surprise that it’s now finding its way into the world of architecture and design. As we strive to create more sustainable and efficient buildings, AI has the potential to revolutionize the way we approach the built environment. By exploring the intersection of AI and sustainable architecture, we can unlock the next generation of design solutions that will help shape the future of our cities and communities.

One of the most significant ways AI can contribute to sustainable architecture is through the optimization of building design. Traditionally, architects and engineers have relied on their experience and intuition to create energy-efficient buildings. However, AI algorithms can analyze vast amounts of data and consider numerous design variables to identify the most sustainable and cost-effective solutions. This data-driven approach can lead to more innovative designs that minimize energy consumption, reduce waste, and lower the overall environmental impact of buildings.

For example, AI can be used to optimize the orientation, shape, and size of a building to maximize natural light and minimize heat gain. This can result in a more comfortable indoor environment while reducing the need for artificial lighting and air conditioning. Similarly, AI can help architects select the most appropriate materials and construction techniques to improve a building’s thermal performance and reduce its carbon footprint.

Another area where AI can make a significant impact is in the design of urban environments. As cities continue to grow and urban populations increase, there is a pressing need to create more sustainable and livable urban spaces. AI can be used to analyze complex urban systems and identify the most effective strategies for improving air quality, reducing traffic congestion, and promoting walkability and public transportation. By using AI to inform urban planning decisions, we can create more sustainable and resilient cities that are better equipped to face the challenges of the future.

In addition to optimizing design, AI can also play a crucial role in the ongoing management and maintenance of buildings. By integrating AI with building management systems, it’s possible to monitor and analyze the performance of a building in real-time. This can help identify inefficiencies and potential issues before they become significant problems, allowing for more proactive maintenance and reducing the overall environmental impact of a building throughout its lifecycle.

Furthermore, AI can be used to create more responsive and adaptive buildings that can adjust to changing conditions and occupant needs. For instance, AI-powered systems can learn from occupants’ behavior and preferences to optimize lighting, heating, and cooling, resulting in a more comfortable and energy-efficient environment. This level of personalization can not only improve the overall user experience but also contribute to greater sustainability by reducing energy waste.

As we continue to explore the intersection of AI and sustainable architecture, it’s essential to consider the ethical implications of these emerging technologies. While AI has the potential to revolutionize the built environment, it’s crucial to ensure that these advancements are used responsibly and equitably. This includes addressing issues related to data privacy, algorithmic bias, and the potential displacement of human workers in the design and construction process.

In conclusion, AI offers a wealth of opportunities for creating more sustainable and efficient buildings and urban environments. By harnessing the power of AI, architects, engineers, and urban planners can develop innovative design solutions that minimize environmental impact, improve building performance, and enhance the overall quality of life for occupants. As we continue to explore the intersection of AI and sustainable architecture, we can look forward to a future where our built environment is smarter, more resilient, and more sustainable than ever before.

Accelerating low-carbon building design & development is the leitmotiv of American design practice as envisaged by SOM.  This article on and by Sustainability elaborates on how this is attained.

SOM: Accelerating low-carbon building design & development

Skidmore, Owings & Merrill (SOM) launches the Whole Life Carbon Accounting service to help accelerate low-carbon building design & development

.

Skidmore, Owings & Merrill (SOM), a worldwide alliance of architects, designers, engineers and planners, has introduced a new service aimed at accelerating the implementation of low-carbon and net-zero buildings.

The initiative, named Whole Life Carbon Accounting, is a system used to assess and measure the operational and embodied carbon emissions of a building throughout its entire lifespan.

When the system is incorporated during the design phase, it offers a precise picture of the proposed building’s carbon footprint, enabling investors, property owners and developers to make well-informed decisions. By evaluating a building’s performance after completion, the service enables owners to monitor progress and achieve their long-term sustainability goals.

“The greatest opportunity to work towards a more sustainable future is to invest in new climate action measures,” said Kent Jackson, SOM Design Partner. “We are proud to extend our long and proven history of working with public bodies, property owners and developers to help lead the way for a low-carbon built environment. We look forward to bringing our skills and expertise to bear on the critical issue of a reduced carbon future.”

.

The shift towards whole-life carbon

Accounting for approximately 40% of carbon emissions worldwide, the built environment has long prioritised the reduction of operational energy and its carbon emissions. However, there has been a significant shift in focus towards whole-life carbon, changing the way buildings are designed, constructed and renovated.

Embodied carbon – the carbon impact associated with a building’s initial construction – cannot be rectified later, whereas operational energy and associated carbon emissions can be improved to a certain extent once a building is in use.

“The built environment urgently needs new approaches to performing carbon assessments. Innovation is driven by a diversity of ideas and voices,” says Mina Hasman, SOM Sustainability Director. “Evidence shows that as a project develops and design strategies evolve, the gaps between traditional assessments and a building’s true performance can lead to a performance gap of up to five times more energy use and/or carbon emissions between predicted and actual values.

“Our service puts an end to this. As regulators and investors evaluate new and existing assets more closely, we provide clients with practical strategies to help inform their investment, development and management activities.”

Applying SOM’s interdisciplinary approach, the firm’s sustainability team analyse and measure operational and embodied carbon emissions across every stage of a project. Clients can therefore gain an understanding of a building’s true carbon impact and the ability to translate carbon targets into measurable performance outcomes.

Carbon assessments are typically performed at the end of design stages by different parties and to different standards. This can result in isolated calculations which are not comparable and cannot effectively illustrate a building’s accurate performance.

The gaps between the projected performance of a design and actual building performance widen as projects develop and designs evolve. Consequently, calculations can constitute as little as 20% of actual carbon emissions. This can affect a building’s value and viability in the long term.

The holistic approach has led to internationally-acclaimed projects, including the LEED Platinum Billie Jean King Main Library, completed in California in 2019.

The building is one of few in the region that features a lightweight timber structural system, to build the library atop an existing underground concrete parking garage. It was also named 2021 Project of the Year by the US Green Building Council and was the winner of the Metropolis Magazine Planet Positive award.

Additionally, SOM achieved a remarkable 61% reduction in embodied carbon compared to a typical concrete building, by preserving most of the original concrete structure.

SINGAPORE, June 13 (Reuters) – Global reservoir volumes fell during the last 20 years despite a construction boom that drove up storage capacity, a new study showed on Tuesday, suggesting that new dams will not be enough to solve growing strain on the world’s water supplies.

Satellite data showed that water sequestered in 7,245 reservoirs across the world fell from 1999 to 2018, despite a 28 cubic kilometre annual increase in capacity, a study published by Nature Communications said.

Climate change was a “critical factor” in reducing reservoir efficiency, said lead author Huilin Gao of Texas A&M University, but rising water demand also played a role.

“Even if temperatures stop rising, increasing demand and new construction are likely to continue,” he added.

The decline in storage volumes was concentrated in the south, especially Africa and South America, where water demand increased rapidly and new reservoirs didn’t fill up as quickly as expected.

The study did not account for the impact of sedimentation, a persistent problem that is predicted to cut storage capacity by a quarter by 2050, according to a January paper by the United Nations University.

Lengthy droughts have raised questions about the feasibility of large reservoirs. China saw hydropower output plummet last summer as a result of record-high temperatures across the Yangtze basin.

The International Hydropower Association said last week that new dams and reservoirs played a “crucial mitigating role in an era of increasing climate extremes”, making it easier to regulate water flows.

“As the climate gets more volatile, we will need more, not less, water infrastructure, with the bonus of much-needed low-carbon electricity,” it said.

China has also repeatedly said its enhanced ability to store and release water on the upper reaches of the Yangtze has alleviated downstream floods and droughts

Unlike many regions, China’s storage levels increased slightly over 1999-2018 as a result of higher run-off in major river basins, suggesting it will benefit from new reservoirs, Gao said.

“But this highly depends on future climate, especially since most regions have experienced decreasing run-off,” he said.
