13 Urban Trends to Watch // Urban Land Institute

13 Urban Trends to Watch // Urban Land Institute | green streets | Scoop.it
In an excerpt from his new book, Urban Real Estate Investment: A New Era of Opportunity, Henry Cisneros making the case for the forces of change that will create a new urban reality.

The contours of an urban renaissance—long in the making—are quickly coming into focus. Massive societal and economic changes are converging to create a new urban reality, a transformation of importance to the millions of Americans in the nation’s metropolitan areas. Demographic changes are creating markets for mixed-use and mixed-income models of urban design. Job growth in advanced industries fits the preferences of knowledge workers attracted to urban neighborhoods. The “smart” institutions of the new economy, such as research universities and medical centers, are becoming the knowledge anchors of cities, spinning off employment, contracts, businesses, residences, and public amenities. Global energy challenges are putting a premium on core city locations and on public transit. New technologies are matched to creative financial architecture to advance concepts of sustainability, walkability, and affordability...

7 Cities That Are Starting To Go Car-Free

7 Cities That Are Starting To Go Car-Free | green streets | Scoop.it
Urban planners are finally recognizing that streets should be designed for people, not careening hunks of deadly metal.

After over a hundred years of living with cars, some cities are slowly starting to realize that the automobile doesn't make a lot of sense in the urban context. It isn't just the smog or the traffic deaths; in a city, cars aren't even a convenient way to get around.

Now a growing number of cities are getting rid of cars in certain neighborhoods through fines, better design, new apps, and, in the case of Milan, even paying commuters to leave their car parked at home and take the train instead.

Unsurprisingly, the changes are happening fastest in European capitals that were designed hundreds or thousands of years before cars were ever built. In sprawling U.S. suburbs that were designed for driving, the path to eliminating cars is obviously more challenging.

Accessibility and Urban Elevators: Urban Link by VAUMM

Accessibility and Urban Elevators: Urban Link by VAUMM | green streets | Scoop.it

Spanish architects VAUMM have found a niche in Errenteria, a town near San Sebastián where they have now completed three ascensores urbanos (‘urban elevators’). The region underwent rapid industrialisation in the 1960s that caused residential construction to climb steep hillsides. The resulting urban obstacle course continues to present problems of accessibility and connectivity for the aging population that the construction was originally designed to accommodate. VAUMM’sascensores act as vertical cross-streets, creating navigable pathways between previously disconnected places.

Urban farms won't feed us, but they just might teach us

Urban farms won't feed us, but they just might teach us | green streets | Scoop.it

It's clear that the craze for the urban farm is no answer to feeding our teeming cities. Its value lies instead in how it can change us.


If we want to scale up regional food systems, it seems like it would be a great idea to grow a significant amount of our calories right in our cities. It’s a beautiful concept, reuniting humans and nature to solve many of the problems brought about by our urbanization. But talking to urban farmers and reading the recent research turned a cold hose (of reclaimed rooftop drain water) on my enthusiasm.

There’s a backlash underway against the general exuberance over urban farming, and, surprisingly, it’s coming from urban farmers. It’s a measured, cautious backlash — less pendulum swing than correction...

Urban Farming is not the only solution towards feeding the growing population in cities but it certainly contributes to greater food resilience, habitat and biodiversity in cities. It makes a valuable contribution to local economy and food access which is part of a much bigger picture.

Russell Roberts's curator insight, May 2, 2014 12:08 AM

Thanks to reporter Wes Thomas for this article on the pros and cons of "urban farming."  With food costs rising and supply timetables in flux, many city dwellers are considering some form of food self-sufficiency.  This article tempers some of that early enthusiasm with a needed dose of reality...farming, urban, or not is hard work.  Nonetheless, food and water are becoming the next resource battleground.  Both of these survival elements are being strained by a growing world population.  If these trends continue, Hawaii may not be able to afford the importation of food and fuel.  We may have to "go it alone" in the future.  One thing is for certain, food prices will continue to rise in a world of diminishing resources.  A very sobering article.  In short, there are too many mouths to feed with a slowly declining ability to feed them.  Aloha, Russ.

Nueva vuelta de tuerca a un tema relacionado con los techos verdes, asunto que traté recientemente en esta curación de contenidos. 

 

En su artículo, Nathanael Johnson alude a los beneficios que pueden suponer estas granjas o huertos urbanos sobre los ciudadanos, tanto desde el punto de vista de acceso a unos productos de calidad como en relación con el beneficio económico que puede generar en los productores. En relación con esta fuente de ingresos, el autor pone como ejemplo la empresa Lula Farms, proyecto que se inicio en una azotea de Montreal y que actualmente proporciona beneficios estables (http://bit.ly/1qymQyo).

 

Obviamente, son necesarias unas estructuras mínimas tales como una superficie lo suficientemente amplia y plana para que la inversión merezca la pena, siendo igualmente necesaria una estructura sólida que pueda soportar el peso sin problemas. No obstante, también pueden ser viables las conocidas como granjas verticales.

Water-proofing the Future: Floating Cities & Innovative Architecture

Water-proofing the Future: Floating Cities & Innovative Architecture | green streets | Scoop.it

The lure of the sea: Pacific islands perched in glistening aquamarine, softly lapping waves caressing Europe’s beaches. Now, many of these bucket list hotspots are about to be reclaimed by our beloved sea.

Naturally, we know all about rising sea levels. Cities like Venice as well as entire coastal regions, a. o. in The Netherlands, are acutely threatened by this development. But what can we do to stave off the danger?

Climate change and the resulting greenhouse effect are in full swing. Even a truly radical gear change and turnaround in climate politics would leave our planet fighting the repercussions for a century to come. Against this background, scientists and architects join forces to develop protective solutions for people and the ground they stand on.

'Public art is increasingly an interactive, community-based experience. A focus on “social practice,” or engaging local communities in creating change through art, is borne out in public art pieces that are as thought-provoking as they are aesthetically pleasing.

Urban Characters: Exploring the places and objects that make each city unique | green streets | Scoop.it
A salute to those special places—some humble, some utterly utilitarian—that give a city its unique personality and collective soul.


The six places and objects shown at the link are urban amenities of a particular kind, but really they’re much more than that. These are the distinct features in the landscape that give a city its unique character. Every city has them. They can be supremely useful (the parkettes in Toronto, Pike Place Market in Seattle, Washington, D.C.’s fabulous subway stations) or gloriously idiosyncratic (the hidden staircases in Los Angeles, Pittsburgh’s charming Inclines, the incongruous gas lamps of sunny San Diego).

All of them, however, play a beloved civic role that transcends their mere function, lending a kind of quiet poetry to daily life, grace notes to the grind. Six writers and designers, one from each city, reflect on these special characters in the urban landscape...

Sprouting Eco-Cities: Sustainability Trend-Setters Or Gated Communities?

Sprouting Eco-Cities: Sustainability Trend-Setters Or Gated Communities? | green streets | Scoop.it

Not only are many cities bursting at the seams from urban overcrowding; they are also increasingly starting to bear the strains of climate change.

Although there are numerous solutions to either challenge, the building up of new "eco-cities" tries to kill the two birds with one stone. But what is the role of these master-planned communities in our sustainable futures?

The concept of an isolated, ecologically minded community is by no means a new one. The forward-thinking Buckminster Fuller was talking about "domed communities" in the 1960s, and in 1975 writer Ernest Callenbach published his novel Ecotopia, greatly influencing the green movements that would quickly follow.

While smaller versions may have grown more organically, contemporary Eco-Cities are often top-down master plans designed by big-name firms. Since many of these Eco-Cities are still under development, we can only speculate about their future performance and whether they will be flexible enough to function as a "real city."

'Shadowless' Towers Proposed for London's Urban Fabric

'Shadowless' Towers Proposed for London's Urban Fabric | green streets | Scoop.it
NBBJ proposes a set of "shadowless" towers for London's rapidly changing skyline.

Architects from the global firm NBBJ have designed what they call a “No Shadow Tower” for a site along the Thames River in London. The hypothetical scheme, developed in response to a call for ideas from the architecture think tank New London Architecture (NLA), offers one way to lessen the impact of tall buildings on the urban fabric surrounding them.


NBBJ’s proposed scheme has a similar goal to Jean Nouvel’s recently completed One Central Park complex in Sydney, which depends on a giant heliostat to illuminate a garden that would otherwise often be in shade. But NBBJ uses the geometry of the buildings themselves to mitigate their shadows. The two London towers subtly twist and flair, with floor plates that are slightly larger on the upper floors. Developed with parametric design, the configuration is intended to reflect sunlight from the south face of the taller tower into the plaza below. This arrangement would create what Coop describes as dynamic pools of light...


more...
Lola Ripollés's curator insight, April 5, 2:25 PM

Despite its name, the NBBJ proposal consists not of a single tower, but a pair of glass-clad skyscrapers—one about 50 stories tall and the other about 30 stories. Kidney-shaped in plan, with their concave elevations facing each other, the two buildings together define a plaza at the ground. This space captured NBBJ’s attention. “Although tall buildings have an impact on the skyline, their success or failure comes down to what occurs at the base,” says Christian Coop, design director of the firm’s London office.

St. Louis’ Grand Center neighborhood has gone through a lot of changes, and the midtown neighborhood aims “to become the premiere cultural and entertainment tourist destination in the Midwest.

Part of that plan involves sprucing up the urban fabric with a Great Streets Projects grant from the East-West Gateway Council of Governments.

The plan envisions corridors of development and pinpoints several intersections and cross-block connectors that could be activated by public programming to function as “outdoor rooms.”

Trees and green infrastructure are meant to alleviate some of St. Louis’ flooding issues by retaining and filtering stormwater and describes a new catchment area. Branding, wayfinding, lighting, and transportation analyses are also a focus of the plan.

Bright Lights, Big City: urban-lighting projects that dazzle

Bright Lights, Big City: urban-lighting projects that dazzle | green streets | Scoop.it
As well as ensuring that streets and public spaces are safe and attractive, one of the key concerns of city planners today is reducing energy consumption. For this reason, the evolution of energy-efficient lighting technologies such as LEDs has had a huge influence on the latest generation of street lights. The Rama LED from Spanish design brand Santa & Cole illustrates how the introduction of cutting-edge light sources enhances the performance of these products. Originally designed by Gonzalo Milá in 2000, the updated LED version provides a direct light that minimises light pollution and can be controlled accurately. Like other LED street lamps, it also has an impressive longevity of over 60,000 hours, meaning minimal maintenance is required.

A (Thought) Bubble to Help China Tackle Pollution

A (Thought) Bubble to Help China Tackle Pollution | green streets | Scoop.it

We all know about the shocking statistics regarding the Mainland's pollution, as well as some of the drastic measures it has experimented with to battle it. London-based practice Orproject has come up with a temporary solution for this crowd, one that would transport the Bucky Ball and its biosphere into the contemporary situation in China.

The idea behind the “Bubbles” concept is to encapsulate a park or a garden under a transparent shell to provide an urban oasis of clean air for the citizens to enjoy. Made from ethylene tetrafluoroethylene (ETFE), the structure would maintain a visual delicacy while providing a secure barrier to allow for the control of heat and humidity within. Mimicking the function of a leaf, the form will be covered with translucent solar cells (for conceptual "photosynthesis") and riddled with a series of veins that would function as the circulatory system of the park.

Smart cities: innovation in energy will drive sustainable cities

Smart cities: innovation in energy will drive sustainable cities | green streets | Scoop.it

'Cities represent three quarters of energy consumption and 80% of CO2 emissions worldwide, and represent the largest of any environmental policy challenge. Urbanisation is only set to increase, cities house half the world's population today but are set to host three quarters in 2050.

To cope with this continued urban growth we will need to invent new ways to manage cities and make them more effective. The convergence between digital technology and the world of energy, or Energy 3.0, will pave the way for a new ecosystem of services which will enable both a better quality of life and reduced energy consumption.'

Empowering people in smart cities

In the same way that the IT revolution has been driven by consumer needs, so too will the energy revolution. As blogs, social networks and video platforms have enabled people to produce information and customise their content, new technologies will make possible energy self-production and customisation of energy usages and consumption.

 

Smart cities will also enable the use of open data which will create new urban services such as better transport connections, accident risk warnings and home monitoring for part-time and full-time carers. Local councils will have greater responsibility for ensuring the collection and the public availability of this data.

 

Furthermore, by leveraging this data, businesses will be able to offer personalised services for users, for example smart meter data could permit utilities to offer new tariffs, such as time-of use pricing which will encourage end-users to use energy in off-peak times when it is cheaper.

Whether it’s repurposing a billboard to act as a humidity collection system for clean drinking water in Lima, Peru, or integrating Wi-Fi capabilities into Madrid’s paving stones with the iPavement initiative, cities are increasingly expanding the capabilities of their existing assets and reforming the urban terrain as a landscape of opportunity.

Climate change is one of the most serious issues facing the world's cities in the 21st century, but so far policymakers, planners, and scientists have come up with few solutions to prevent—or mitigate—its calamitous effects.

While flooding disasters like Hurricanes Katrina and Sandy have brought attention to the dangers posed by stronger storms, there are plenty of other threats—such as rising sea levels—that might be even more pressing.
