Designing The Innovation Economy: Using Technology To Shape The Future City

Designing The Innovation Economy: Using Technology To Shape The Future City | Développement durable et efficacité énergétique | Scoop.it
With technological change marching forward at a rapid clip, city environments are being reshaped and the urban experience is being reimagined.

Nearly ubiquitous mobile access has provided visitors and residents with the ability to unlock the “secrets” of the city, opening the door to new experiences and improving livability and user-friendliness. However, in order to make the best of these changes, policy must welcome and support innovation and the urban transformation that accompanies it—and there’s no one-size-fits-all formula...

Unraveling the mysteries of life

Unraveling the mysteries of life | Développement durable et efficacité énergétique | Scoop.it

Time, space and matter were created 13.7 billion years ago, when the Big Bang occurred. This pale, blue planet, so termed by Carl Sagan, our earth, came into existence about 4.5 billion years ago. Life originated on earth about 3.8 billion years ago. Our species, the home sapiens, came much later at about 0.2 million years while recorded history is merely 6000 years old.
However in the last 60 years or so, man has started to unravel many secrets of his own existence. There have been extremely rapid advances in science and mankind is now grappling with very profound aspects of life from intelligence, perception, aging all the way to death itself.
Moving forward to the next 60 years, there are several areas of research, which will have an extraordinary impact on our lives as we move forward.

Sustainable Innovation at Gardens By The Bay, Singapore: World Building of the Year

Sustainable Innovation at Gardens By The Bay, Singapore: World Building of the Year | Développement durable et efficacité énergétique | Scoop.it

Much of the environmental control is achieved through passive means, before resorting to less efficient, active systems such as air conditioning. Fresh air filters through a desiccant, then to conventional chillers. As the desiccant extracts moisture, it also cools the air inside. But to keep the desiccant functioning, energy is needed to remove the accumulated moisture. This is where sustainable technologies come in: An on-site biomass boiler—fueled entirely with green waste from the city’s national parks—and hot air collected from the top of the glasshouses provide sufficient energy to cool the conservatories.

 

“The result is not an experimental building, but its ventilation strategy has an experimental component,” Finch said. “In a globalized environment, there is so much interest in how we deal with density and this combination of urbanism with a garden that is both an attraction and nature is a wonderful solution. If they can cool these glasshouses through natural cooling, we should ask why it can’t be done in other buildings?”

Open Data: a platform to improve city infrastructure + public services

Open Data: a platform to improve city infrastructure + public services | Développement durable et efficacité énergétique | Scoop.it
Many cities are adopting data analytics to improve public services.

Cities are learning that data collected can be used to shorten transit times, assist in the replacement of failing infrastructure, and even make parking easier. In this always-developing technology of data analytics, many cities have already witnessed improvements. At a time when infrastructure funding at the federal level has been cut, U.S. cities are embracing technologies that lower costs while improving services. Global cities are also benefiting from the cost-savings of data analytics.

Some are claiming that data analysis technologies are creating cities as a platform. Paul M. Davis of Shareable writes that “…cities are embracing the concept of the “city as a platform,” a hyper-connected urban environment that harnesses the network effects, openness, and agility of the real-time web.” I agree that as cities adopt network technologies, they will become platforms themselves. And as platforms, cities can leverage data to implement necessary changes and act as a source for businesses and stakeholders through open data networks.

We are already seeing cities that have adopted data analytics open the data to tech firms and developers. This offers a new avenue for further improvement. Moreover, open data increases transparency...

Smart Cities: Technology, Sustainability & Innovation for a Better World

Smart Cities: Technology, Sustainability & Innovation for a Better World | Développement durable et efficacité énergétique | Scoop.it

They only occupy two per cent of the Earth’s land mass, but cities today use a huge amount of the planet’s natural capital, consuming 75 % of global resources and generating 80 % of global greenhouse gas emissions.

As the world population grows to 9 billion by 2050, the number of those living in urban areas will swell by 3 billion to 6.3 billion. With demand for energy and resources set to spike on the back of urban population growth, smart cities have emerged as the modern answer to the wave of urbanisation sweeping across the globe.

 

What defines a smart city?

Put simply, smart cities integrate diverse technologies to reduce its environmental impact. Using a more formal definition from a recent report by the United Cities and Local Governments, smart cities use new technologies, innovation and knowledge management to become more liveable, functional, competitive and modern, bringing together six key fields of performance: the economy, mobility, the environment, citizenship, quality of life and management.

Data Visualization: Explore the United States of Energy

Data Visualization: Explore the United States of Energy | Développement durable et efficacité énergétique | Scoop.it

Finally… After almost 50 years of dependence on foreign sources to meet our growing energy needs, our country is finally in a position to begin reversing the trend. Through advances in drilling technology, discoveries of new oil and natural gas reserves and swift progress in the renewables sector, the United States is setting a course for energy self-sufficiency.

The complex story of energy in America and making it relevant to an increasingly distracted public remains one of our biggest challenges as energy industry communicators. In the information economy, there’s a lot of loose change. Content that lacks context. A rapidly growing punditocracy. An immense amount of noise.

Someone has to break through.

 

In the spirit of this endeavor, we created the United States of Energy map, the first data visualization piece of its kind to comprehensively detail our nation’s vast and diverse energy portfolio...

New green design methods to revolutionize the building industry...

New green design methods to revolutionize the building industry... | Développement durable et efficacité énergétique | Scoop.it

If you want a preview of the downtown Vancouver streetscape in 2035, start with a walk down Granville or Georgia Street today.

Most of the buildings will still be standing. There will be additions and replacements, but most of the changes that will transform downtown's living, work and retail space will be undetectable from the sidewalk. That includes upgrades to water and energy systems in buildings that in 2012 are models of inefficiency by contemporary standards, let alone future ones.

"If you are thinking 2035, realistically 80% of the buildings that will be in existence at that time have already been constructed," said Innes Hood, a professional engineer and senior associate with Stantec Consulting, a consulting firm with 12,000 planners, architects, engineers, project managers and experts, working in teams to break down the boundaries between designers, contractors and investors, while using advanced computer modelling programs.


Retrofits are crucial.

One of Hood's main assignments is overseeing the redevelopment of existing buildings. More often than not, that means uncovering, through energy audits, glaring examples of waste - air leaks, inadequate insulation, inefficient heating and ventilation systems.

"We are involved in residential projects where we can achieve 80-per-cent reduction in energy use and become essentially greenhouse gas neutral through the implementation of cost-effective technologies," Hood said. "We're not having to strive to the leading edge. These are tried and true technologies around good building enclosures and high-performance mechanical systems such as heat pump technology...

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over | Développement durable et efficacité énergétique | Scoop.it

At the moment, wind power supplies about 4.1 percent of electric power in the United States. Still a bit player. Yet there’s a whole lot of untapped wind left in the world. Wind whipping through the Great Plains. Wind gusting off the shores. Wind circulating high up in the sky. So what would happen if we tried to harvest all of that wind?

 

We’d have enough energy to power the world. At least in theory. A new study published this week in Nature Climate Change finds that there’s enough wind potential both on the Earth’s surface and up in the atmosphere to power human civilization 100 times over. Right now, humans use about 18 terawatts of power worldwide. And, technically, the study found, we could extract about 400 terawatts of wind power from the Earth’s surface and 1,800 terawatts of power from the upper atmosphere.

 

Even the most optimistic near-term projections for wind power, however, tend to be more restrained. In 2008, the U.S. Department of Energy released a comprehensive report estimating that wind power could provide, at most, 20 percent of U.S. electricity by 2030. And for that to happen, the cost of wind power would have to keep plunging, the number of turbines built would have to steadily increase by about 14 percent each year, and utilities would have to build new transmission lines to accommodate the extra energy.
