Urban Living Cheaper, More Sustainable Than Suburban

UrbanVSuburban

Years of car-focused suburban designs have unleashed problems in the 21st century that we will have to deal with and accommodate. The years of the suburbs are coming to an end and it can’t be soon enough. With every passing years more and more municipalities discover that urban design is the better choice.

The above image is composed of data taken from a report done by Halifax in 2005. Undoubtably the costs of supporting suburban households has only increased relative to urban housing.

Recently, the New Climate Economy released a report titled Analysis of Public Policies that Unintentionally Encourage and Subsidize Sprawl and advocates for a change to policies to encourage better urban design.

The report, Analysis of Public Policies that Unintentionally Encourage and Subsidize Sprawl—written for the New Climate Economy by the Victoria Transport Policy Institute, in partnership with LSE Cities—details planning and market distortions that foster sprawl, and smart growth policies that can help correct these distortions.

Sprawl increases the distance between homes, businesses, services and jobs, which raises the cost of providing infrastructure and public services by at least 10% and up to 40%. The most sprawled American cities spend an average of $750 on infrastructure per person each year, while the least sprawled cities spend close to $500. In its Better Growth, Better Climate report, the New Climate Economy has found that acting to implement smarter urban growth policies on a global scale could reduce urban infrastructure capital requirements by more than US$3 trillion over the next 15 years.

The New York Times ran an article on urban versus suburban costs back in 2010.

So we set out to do the math, based on an apartment and a house in the New York metropolitan area. Here’s what we found: a suburban lifestyle costs about 18 percent more than living in the city. Even a house in the suburbs with a price tag substantially lower than an urban apartment will, on a monthly basis, often cost more to keep running.

It’s very clear that as we populations grow urban design needs to focus on sustainable infrastructure planning and all of us should encourage it.

Copenhagen Designed a Neighbourhood to Cope With Climate Change

Climate change is happening faster than projected and this means that cities need to react sooner than anticipated. We’ve seen efforts in New York that will create barriers against rising sea levels and other cities have done similar infrastructure improvements. Copenhagen has taken the next logical step: converting an existing neighbourhood into one ready for climate change.

The redesigned chunk of the city use vegetation and reigned streetscapes for a future-proof city.

They went for the green option. “Adding sewers is insanely costly, so a green-and-blue [vegetation and water] approach is more economical,” notes Esben Alslund-Lanthén, an analyst at the Copenhagen-based sustainability think tank Sustainia. There was just one challenge: No city has ever tried climate-change-adapting a whole neighborhood using just plants and water. “It’s a huge amount of water that we’ll have to redirect when the next cloudburst hits,” says Flemming Rafn Thomsen of Tredje Natur, the Danish architecture firm chosen for the project. “We looked at St. Kjeld and thought, ‘That’s a lot of asphalt with no function. We can use some of that space for water.’” On top of having little function, the asphalt gave St. Kjeld, a somewhat rundown working-class neighborhood, an even more depressing feel.

The answer, Rafn Thomsen and the city decided, was to tear up the neighborhood’s squares and replace their asphalt covering with what’s essentially a hilly, grassy carpet interspersed with walking paths. Should a storm, flood or rising sea levels hit the Danish capital again, the bucolic mini-parks will turn into water basins, the hills essentially functioning as the sides of a bowl. Thanks to a new pipe system, the squares will even be able to collect water from surrounding buildings’ roofs. Surrounding streets will, for their part, be turned into “cloudburst boulevards.” Under ordinary circumstances, they’ll just be ordinary streets with raised sidewalks, but during floods and megastorms, they’ll become canals, channeling rainwater away from the squares to the harbor. Millions of gallons of water will be dispatched back to the harbor on such aboveground waterways, St. Kjeld becoming a temporary Venice.

Painting Neighbourhoods

Artists Jeroen Koolhaas and Dre Urhahn create community art by painting entire neighborhoods, and involving those who live there — from the favelas of Rio to the streets of North Philadelphia. What’s made their projects succeed? In this funny and inspiring talk, the artists explain their art-first approach — and the importance of a neighborhood barbecue.

This Classroom Makes More Energy Than it Consumes

School
Anderson Anderson Architecture has built a classroom in Hawaii that generates more energy than it consumes, making what they call a “energy positive” building. The term “energy positive” is being encouraged to replace “net zero” as the benchmark for environmental consciousness in architecture.

The classroom does use roof solar panels to generate energy, though the roof’s saw-tooth shape helps to that end. The slating, jagged design is often referred to as a factory roof, deriving from its use in the design of factories more than a century ago. With north-facing windows, this roof shape is particularly efficient at capturing daylight, and paired with lower-lying windows too, it provides ventilation for hot air to escape. Not to mention a good way to shed rain water. Before electricity was widespread, these roofs were the main way massive factories could get both light and ventilation. It fell out of favor, replaced by flat roofs, once electricity became cheaper, but Anderson says it’s still a remarkably effective design. “It’s a reminder some of those things were there for very good reasons,” he says.

A Rebel Architect in Vietnam Creates Green Space

Al Jazeera has a series on rebel architects who are improving the world around them. In the documentary they released today they look at award-winning architect Vo Trong Nghia’s work in reshaping Vietnamese buildings to contain more green space.

This film follows Nghia as he tries to find support for his vision to create a vertical farming city; and at the same time to implement low-cost housing solutions for those left behind by Vietnam’s economic boom.

“Green architecture helps people live harmoniously with nature and elevates human life by embracing the powers of the sun, wind and water into living space. If the current way of thinking does not change, sooner or later citizens will actually live in concrete jungles. For a modern architect, the most important mission is to bring green spaces back to the earth.
