The Anatomy of a Smart City
There is no doubt that the city will be the defining feature of human geography for the 21st century.
Globally, there are 1.3 million people moving to cities each week – and by 2040, a staggering 65% of the world’s population will live in cities.
At the same time, the 600 biggest urban areas already account for 60% of global GDP, and this will only rise higher as cities become larger and more prosperous. In fact, experts estimate that up to 80% of future economic growth in developing regions will occur in cities alone.
The Smart City: A Necessary Step
As cities become an even more important driver of the global economy and wealth, it’s becoming crucial to ensure that they are optimized to maximize efficiency and sustainability, while enhancing the quality of life in each urban conglomeration.
Today’s infographic from Postscapes helps define the need for smart cities, and it also gives great examples of how technology can be applied in urban settings to facilitate cities that work better for their citizens.
Features of Tomorrow’s Cities
Smart cities will use low power sensors, wireless networks, and mobile-based applications to measure and optimize everything within cities.
Here are just some examples: (click below image to open full-size version)
Smart city solutions will fall into six broad categories, transforming the urban landscape:
Smart lighting is one of the most important solutions that will be implemented in citywide infrastructure. While smart lighting sounds trivial at first glance, it’s worth noting that lighting alone consumes a whopping 19% of the world’s total electricity.
Heating, energy usage, lighting, and ventilation will be managed and optimized by technology. Solar panels will be integrated into building design, replacing traditional materials. Fire detection and extinguishing is tailored to individual rooms.
Smart grids (used for energy consumption monitoring and management), water leakage detection, and water potability monitoring are just some smart city aspects on the utilities side.
Intelligent, adaptive fast lanes and slow lanes (cycling, walking) will be implemented, while charging stations through the city will power EVs.
Air pollution control, renewable energy, and waste management solutions will make for greener cities. Rooftop gardens or side vegetation will be integrated into building designs, to help with insulation, provide oxygen, and absorb CO2.
There will be citywide Wi-Fi for public use, while real-time updates will provide citizens information on traffic congestion, parking spaces, and other city amenities.
Cisco estimates that smarter cities will have impressive increases in efficiency: using many of the above concepts, cities can improve energy efficiency by 30% in 20 years.
Simultaneously, it’s estimated that the broad market for smart cities products and services will be worth $2.57 trillion by 2025, growing at a clip of 18.4% per year on average.
The Hydrogen City: How Hydrogen Can Help to Achieve Zero Emissions
Cities are drivers of growth and prosperity, but also the main contributors of pollution. Can hydrogen fuel the growth of cities with clean power?
In the modern context, cities create somewhat of a paradox.
While cities are the main drivers for improving the lives of people and entire nations, they also tend to be the main contributors of pollution and CO2 emissions.
How can we encourage this growth, while also making city energy use sustainable?
Resolving the Paradox
Today’s infographic comes to us from the Canadian Hydrogen and Fuel Cell Association and it outlines hydrogen technology as a sustainable fuel for keeping urban economic engines running effectively for the future.
The Urban Economic Engine
Today, more than half of the world’s population lives in cities, and according to U.N. estimates, that number will grow to 6.7 billion by 2050 – or about 68% of the global population.
Simultaneously, it is projected that developing economies such as India, Nigeria, Indonesia, Brazil, China, Malaysia, Kenya, Egypt, Turkey, and South Africa will drive global growth.
Development leads to urbanization which leads to increased economic activity:
The difficulty in this will be achieving a balance between growth and sustainability.
Currently, cities consume over two-thirds of the world’s energy and account for more than 70% of global CO2 emissions to produce 80% of global GDP.
Further, it’s projected by the McKinsey Global Institute that the economic output of the 600 largest cities and urban regions globally could grow $30 trillion by the year 2050, comprising for two-thirds of all economic growth.
With this growth will come increased demand for energy and C02 emissions.
The Hydrogen Fueled City
Hydrogen, along with fuel cell technology, may provide a flexible energy solution that could replace the many ways fossils fuels are used today for heat, power, and transportation.
When used, it creates water vapor and oxygen, instead of harmful smog in congested urban areas.
According to the Hydrogen Council, by 2050, hydrogen could each year generate:
- 1,500 TWh of electricity
- 10% of the heat and power required by households
- Power for a fleet of 400 million cars
The infrastructure requirements for hydrogen make it easy to distribute at scale. Meanwhile, for heat and power, low concentrations of hydrogen can be blended into natural gas networks with ease.
Hydrogen can play a role in improving the resilience of renewable energy sources such as wind and solar, by being an energy carrier. By taking surplus electricity to generate hydrogen through electrolysis, energy can be stored for later use.
In short, hydrogen has the potential to provide the clean energy needed to keep cities running and growing while working towards zero emissions.
The 100 Tallest Buildings in New York City
This visualization plots out the tallest buildings in New York City, as well as a few in the pipeline that will change the Big Apple’s skyline forever.
The 100 Tallest Buildings in New York City
If you go to the Big Apple, the city’s signature skyline can make quite an impression.
The fact is, New York City has over 6,000 high-rise buildings in total, 274 of which are skyscrapers standing over 492 ft (150 m) tall. It’s an impressive portfolio of real estate, putting NYC as the number two destination globally for such towers, only behind Hong Kong.
But while some of the buildings have dominated the skyline seemingly forever, it’s also a landscape that is changing fast. New projects coming online will be among the city’s tallest, and they will dramatically alter any view of Midtown of Lower Manhattan for future onlookers.
A List of NYC’s Tallest Buildings
Today’s infographic comes to us from Liberty Cruise, and it shows the tallest buildings in New York City.
Here are the individual profiles of the current top ten:
|Rank||Building Name||Height||Completion Date|
|#1||One World Trade Center||1,776 feet (541 m)||2014|
|#2||432 Park Avenue||1,396 feet (426 m)||2015|
|#3||30 Hudson Yards||1,268 feet (387 m)||2019|
|#4||Empire State Building||1,250 feet (381 m)||1931|
|#5||Bank of America Tower||1,200 feet (366 m)||2009|
|#6||3 World Trade Center||1,079 feet (329 m)||2018|
|#7||53W53||1,050 feet (320 m)||2018|
|#8||Chrysler Building||1,046 feet (319 m)||1930|
|#9||The New York Times Building||1,046 feet (319 m)||2007|
|#10||35 Hudson Yards||1,009 feet (308 m)||2018|
Two of the biggest skyscrapers, the Chrysler Building and the Empire State Building, were erected during the Great Depression and still crack the top ten list today.
The Chrysler Building was actually the first skyscraper ever to be built at a height exceeding 1,000 feet. Meanwhile, the Empire State building, which was finished one year later, was the “world’s tallest building” for nearly 40 years.
However, as you can see, the rest of the buildings on the top ten list are more recent builds. It’s a testament to how fast the skyline of New York City has changed even in the last decade.
Towers in the Pipeline
But that’s not all, because the skyscraper boom in NYC hasn’t ended yet. The following megatowers are closing in on completion, and will displace many at the top of the current list:
111 West 57th Street
This building is set to be operational in mid-2019, and it’s already very noticeable on the NYC skyline. With a height of 1,428 feet (435 m), it will be the “skinniest” skyscraper in the world when completed, with a width-to-height ratio of 1:23.
Central Park Tower
This building, which was designed by the same people who did the Burj Khalifa in Dubai, will be the tallest building in the country by roof-height when done in 2020. It will clock in at 1,550 feet (472 m), making it the most sky-high residential building in the world.
45 Broad Street
With a height of 1,200 feet (366 m), this new building in Lower Manhattan is expected to be completed by 2021. If it were finished today, it would tie the Bank of America Tower for the fifth spot on a list of tallest buildings in the city.
This massive building will be the fourth tallest in the city when completed in 2021. Standing at 1,401 feet (427 m), it will have a highly anticipated observation deck set 1,000 feet above the ground.
