Hot in the City: Reducing Heat from Urban Waste

Hot in the City: Reducing Heat from Urban Waste | Greener World | Scoop.it

Cities are hotbeds of sustainability, right? From urban agriculture to social enterprise, you’ll find lots of innovative approaches in urban centers, particularly those on the US coasts. Put a lot of people together in one place, and you generate a lot of ideas.


You also generate a lot of heat, it turns out: a new study in Nature Climate Change argues that urban centers (particularly on coasts) generate a lot of waste heat… and that heat is contributing to the weird weather patterns we’ve been seeing lately. This isn’t climate change (in the way we’ve conventionally considered it), nor is it the “urban heat island” effect. Rather, according to the research team that authored the study...

About time something should be done on exhausts coming from cities.

I think this new research proves how much little things we do in the city, such as driving back and forth to a shopping mall everyday, effects the environment and impacts the weather. I live in Florida and I really don't want an even hotter summer when I go into the city, so I hope people (including myself) think about the environment and make better decisions when we are heading to town, like maybe riding a local bus from place to place or car pulling with friends. -RT

This article really makes you think about how we take advantage of the opportunities for resource sharing offered in urban settings. I think people don't have to make a place hotter by generating heat. For instance instead of driving your car to work, you could ride a bike or a bus. -CB

Climate-Proofing Urban Areas with Floating Housing

Climate-Proofing Urban Areas with Floating Housing | Greener World | Scoop.it

The wave of floods that hit Britain in April focused attention, once again, on the vulnerability of homes in low-lying areas...

But what if a house could simply rise and fall with the waters? That’s the vision of Baca Architects, designers of the UK’s first ‘amphibious house’, which has just received planning permission for a site near Marlow, in Buckinghamshire, on the banks of the Thames.

The lightweight, timber-framed structure sits on a floating concrete base that is built within a fixed ‘wet dock’ foundation. In the event of a flood, the concrete base rises up as the dock fills with water, ensuring the house floats safely above the waves. The base effectively acts as a free-floating pontoon, and should have a lifetime of around 100 years before needing renewal or replacement.

Climate proofing’ urban areas is a growing area of focus for architects and planners. Amphibious architecture looks set to join rain gardens, green roofs and permeable paving in the array of techniques available...

Creative concept. I wonder how they plan to ensure grounding / earthing the electrical system.

Anatomy of a Smart City

Anatomy of a Smart City | Greener World | Scoop.it

The 19th century was a century of empires, 20th century was a century of nation states and the 21st century will be a century of cities...

This outstanding infographic (courtesy of postscapes.com) begins with some information about our current state of urbanization.

Did you know that 1.3 million people are moving to cities each week?! It then explains the need for smart cities and delves into what is required to establish these intelligent connected environments, how the smart city may take various forms in the developing worlds and what specific technologies are necessary to achieve such grand goals in practice.

There is an evolution taking place where politics, policy, technology, the environment, and the economy all intersect. This movement towards technical, empirically driven local policy making could be our saving grace.This could be the future of government.

A stunning infographic which predicts how urban living will change in this century.  Our age is truly becoming "a century of smart cities."  Exciting times lie ahead.  Aloha, Russ.
