Animation: The Population Pulse of a Manhattan Workday

Published

on

In cities around the world, the offices and storefronts of the downtown core fill up with people during the workday to keep the wheels of commerce turning.

Nowhere is this phenomenon as pronounced as in Manhattan, which swells to an incredible four million people during work hours. Today’s animation, created by Justin Fung, is a dramatic, eye-opening look at the “pulse” of America’s largest city.

This dramatic shift in population on a daily basis is made possible by Manhattan’s unparalleled carrying capacity, or its ability to facilitate an inflow of millions of people who come for all sorts of reasons. Many of the metropolises with the most dramatic daytime population spikes, such as Washington, D.C. and New York, also have much higher rates of transit ridership than the average city.

Not surprisingly, three surrounding boroughs have the largest daytime population decreases in the entire country.

BoroughDaytime Population Change
Queens-366,000
Brooklyn-297,000
Bronx-162,000

Outside the Big Apple

While many parts of Manhattan remain lively in the evening, many downtown cores around the country simply empty out.

This stark contrast is particularly noticeable in low-rise communities with large employment hubs such as Redmond, Washington or Palo Alto, California, both of which are home to sprawling tech campuses.

Daytime population increases

In the case of the nation’s capital, the city is a powerful magnet for talent. As well, Washington’s unique position between state lines means that people have the option of residing in Virginia or Maryland and easily commuting in.

Higher Resting Heartbeat

Thanks to a renewed interest in urban living, many cities are starting to see an uptick in the number of residents who choose to skip the long commute and just live where the action is.

This trend is particularly pronounced in Canadian cities such as Vancouver and Toronto. The latter city’s downtown population is expected to double over the next 25 years, while Vancouver’s sustained real estate boom has added tens of thousands of residents to the downtown area.

In the U.S., Seattle has demonstrated significant urban residential growth. Since 2010, the population of downtown and surrounding neighborhoods has grown by an impressive 18%, and 1-in-5 people moving to the city choose to live in the downtown area.

The 2020 U.S. Census will provide a much better clearer picture of how this trend is playing out.

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?

Published

on

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 Hydrogen City: How Hydrogen Can Help to Achieve Zero Emissions

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:

RankBuilding NameHeightCompletion Date
#1One World Trade Center1,776 feet (541 m)2014
#2432 Park Avenue1,396 feet (426 m)2015
#330 Hudson Yards1,268 feet (387 m)2019
#4Empire State Building1,250 feet (381 m)1931
#5Bank of America Tower1,200 feet (366 m)2009
#63 World Trade Center1,079 feet (329 m)2018
#753W531,050 feet (320 m)2018
#8Chrysler Building1,046 feet (319 m)1930
#9The New York Times Building1,046 feet (319 m)2007
#1035 Hudson Yards1,009 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.

One Vanderbilt
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.
