Smart Highways by Studio Roosegaarde

Smart Highways by Studio Roosegaarde | green streets | Scoop.it

Glow-in-the-dark roads and responsive street lamps were among the concepts to make highways safer while saving money and energy at the Design Indaba conference in Cape Town earlier this month.


The Smart Highways project by Studio Roosegaarde proposes five energy-efficient concepts that will be tested on a stretch of highway in the Brabant province of the Netherlands from the middle of this year.

The first of the concepts is a glow-in-the-dark road that uses photo-luminescent paint to mark out traffic lanes. The paint absorbs energy from sunlight during the day the lights the road at night for up to 10 hours. Temperature-responsive road paint would show images of snowflakes when the temperature drops below zero, warning drivers to take care on icy roads.

There are two ideas for roadside lighting: interactive street lamps that come on as vehicles approach then dim as they pass by, thereby saving energy when there is no traffic, and "wind lights" that use energy generated by pinwheels as drafts of air from passing vehicles cause them to spin round. Additionally, an induction priority lane would incorporate induction coils under the tarmac to recharge electric cars as they drive...

First we learned to sequence traffic lights.  Now we can capture energy for better road marking.  Next we will have computer guided car tracks that let us travel more efficiently as a group better utilizing existing highways.  Add in more fuel efficient or electric cars and we have a pretty good outlook for cleaner cities and less dependency on non-renewable resources.

If there is one area that needs focus and improvement it is highways. Agreed!

How New York aims to raise building efficiency by 20 percent

How New York aims to raise building efficiency by 20 percent | green streets | Scoop.it

In an executive order issued at the end of 2012, NY Gov. Cuomo directed state agencies to improve the efficiency of their buildings 20% by 2020.


Going forward, energy efficiency will be considered as a standard part of the capital project planning process.


To implement this efficiency initiative -- among the most ambitious in the U.S. -- Cuomo also announced the start of "Build Smart NY," the implementation arm of the Executive Order.

Using energy data on state buildings, the implementation plan prioritizes the largest, least efficient buildings first for comprehensive whole building retrofits, to get the biggest bang on energy savings for every dollar spent. 

Identifying buildings with the most opportunity to improve is a big part of driving energy savings, but it's not as simple as it appears. Data from New York City shows that some of its oldest buildings are more energy efficient than those that are LEED-certified.

Efficiency measures include the typical, but all important lighting upgrades, advanced heating, ventilating and air-conditioning systems, efficient electric motors and automated energy management systems.

"Improving energy efficiency in our buildings is a smart investment in our present and future," NY Gov. Cuomo says. "Through Build Smart NY, state government can produce significant savings for New York taxpayers and generate thousands of jobs, while reducing greenhouse gas emissions by more than eight million metric tons - which is the same as taking one million cars off the road for one year. Furthermore, most of the projects will pay for themselves as their energy savings will cover their costs, making this initiative a financial and environmental win-win for New Yorkers."

Creating a City-Wide Energy Internet: A new study on urban infrastructure

Creating a City-Wide Energy Internet: A new study on urban infrastructure | green streets | Scoop.it

A new research study addresses the issue of the expanding populations in cities, and provides a solution for adapting urban infrastructure for the needs created by increased density and growth.


Drawing our attention to one core idea that can make our cities more liveable for good, ‘The Time Is Right for Connected Public Lighting Within Smart Cities‘, is a study that looks into the key concepts of urbanization but applies them to a specific context of “an intelligent, networked public lighting infrastructure”. The study dissects the current issues well, reminding us that the urbanization pattern across the world leads to an obviously problematic upswing in energy and resource demand, which in turn threatens the strong identities (inter-city competition and economic performance) that cities across the planet are attempting to shape and maintain.


The solution, according to the report, is the deployment of highly efficient connectivity within cities whether that be information, operational or communication systems – the solution is required urgently. It seems clear that connecting lighting infrastructures will minimize a city’s resource intake, reduce its carbon footprint and make it more resilient and future-proofed. The ripple effects of better lighting systems in cities include safer and more liveable streets (less crime, more appealing urban space and better road safety) and adds to a city’s pull factors for multi-national organisations and tourism...

Thinking outside the parks: Green space spreads in the Big Apple

Thinking outside the parks: Green space spreads in the Big Apple | green streets | Scoop.it

Launched in 1996, the Greenstreets program has transformed much of New York City’s negative space into green space. Greenstreets started small — planting a flowerbed here, a few trees there — and gradually began improving existing infrastructure, like awkward intersections. What once was a concrete median or a matrix of painted lines, for instance, became a raised bed with shrubbery, sidewalks, and crosswalks — even a bench or two.

From there, it grew. Now, Times Square and Madison Square, historically two of the busiest intersections in New York, are pedestrian paradises — with potted plants, wider sidewalks, and café tables.

Greenstreets is now a centerpiece of the city’s effort to enhance inter-departmental collaboration as part of Mayor Michael Bloomberg’s three-pronged approach to maintaining and enhancing city parks. The program brings together New York’s Department of Parks and Recreation with the departments of Transportation and Environmental Protection.

A successful Greenstreet is considered “hyperfunctional” — wider sidewalks mean a more pedestrian-friendly environment, and directing storm water onto planted beds controls runoff and provides needed water to those plants...

What Makes Some Cities Greener Than Others

What Makes Some Cities Greener Than Others | green streets | Scoop.it
Today I turn my attention to the economic, demographic, and other factors associated with cities and metros that have lower levels of carbon emissions.

 

Several Martin Prosperity Institute colleagues and I [Richard Florida] took a simple, straightforward statistical look at several things research and common sense suggest should be associated with higher and lower levels of carbon emissions.

We measure emissions three ways, as a function of population (per capita), workforce (per worker), and economic output (per economic output). All the caveats regarding correlation not being causation apply. However, our findings underscore the fact that carbon emissions are linked as much to the way we live as how we produce and manufacture things...

A Local Living Economy | BALLE

When enterprises are locally rooted, human-scale, owned by stakeholders, and held accountable to the rule of law by democratically elected governments, there is a natural incentive for all concerned to take human and community needs and interests into account.

Energy Efficiency Can Make Billions While Fighting Climate Change

Energy Efficiency Can Make Billions While Fighting Climate Change | green streets | Scoop.it
Energy efficiency could be a huge investment opportunity in the U.S., but better policies are needed to unlock financing, according to a new Ceres study.


Energy efficiency could be a several hundred billion dollar investment opportunity in the United States, but better policies are required to unlock broad-based financing from institutional investors, according to a new study by investor advocacy group Ceres.

The study details the results of a survey of nearly 30 institutional investors and other experts from the energy, policy and financial sectors that identified three areas of policy:

  • utility regulation
  • demand-generating policies and 
  • innovative financing policies


The study finds that these three areas have the potential to take energy efficiency financing to a scale sufficient enough to attract significant institutional investment.

Seven Mico-Living Proposals From The adAPT NYC Competition

Seven Mico-Living Proposals From The adAPT NYC Competition | green streets | Scoop.it

A gallery of studios and apartmentlets of the future, submitted for New York City’s adAPT competition.


The winning submission, My Micro NYC, by nARCHITECTS, Monadnock Development LLC, and the Actors Fund Housing Development Corporation, will be  developed on a site on East 27th Street in Manhattan. The structure will include multi-purpose spaces, lounges, and even an attic garden, providing luxuries not typically associated with efficiency apartments while encouraging interaction among neighbors. But while a lot of attention has been given to the winning proposal, there were actually 33 entries in total, a record within the Housing and Preservation Department.

Connecting the Physical & Digital Worlds: Smarter Systems for Smart Cities

Connecting the Physical & Digital Worlds: Smarter Systems for Smart Cities | green streets | Scoop.it
Technology is being used in ways you would never expect to help solve fundamental problems, from managing a football stadium on game day, to helping manage transportation systems and emergency operations.

As organizations and large facilities like stadiums, museums, schools and government buildings continue to grow and provide more people with faster, better, innovative services, we need to make them more efficient--not by cutting back services, but by getting insight and intelligence on how our physical world functions.
From roads to vehicles to buildings to HVAC systems and lights, thousands of objects not only need to be managed, but how they interact and affect each other must be optimized. By addressing and answering these fundamental questions, we can get real insight to drive better decision making and efficiency.

If we analyze this data, we can find inefficiencies or make connections we never would have imagined. By connecting the physical and digital worlds, these massive organizations that are part of our daily lives can deliver more efficient services to us all...

Designing Water-Efficient Communities

Designing Water-Efficient Communities | green streets | Scoop.it
Harold Smethills explains why—and how—we can design future communities around water conservation.

As managing director of Sterling Ranch, one of Colorado’s most anticipated community developments, Harold Smethills is setting the standard of what it means to build a sustainable community. From wildlife conservation and open space planning to alternative energy sources and community-supported agriculture, Smethills and his development team have one goal for the 3,400-acre proposed community in the Chatfield Basin—to use sustainability as its overriding design principle.

But if you ask him what the critical issue is for his development—not to mention the building industry as a whole—his answer may surprise you. “As we look out to 2020 and far beyond, the very critical issue is water,” Smethills says. “Potable, reliable water is probably is the defining issue for this coming millennia.”

In fact, water conservation has been one of the defining features of Sterling Ranch. The development, which aims to use one-third the water traditionally required in Douglas County, has been recognized by the Colorado Water Conservation Board for it ambitious approach and is being lauded by many as the “blueprint” for designing future water-efficient communities...

Green Roofs in Big Cities Bring Relief From Above

Green Roofs in Big Cities Bring Relief From Above | green streets | Scoop.it
Turning the black tar roofs that cover our cities into green spaces is not cheap or easy, but its benefits to the environment would be great.

It’s spring — time to plant your roof. Roofs, like coffee, used to be black tar. Now both have gone gourmet: for roofs, the choices are white, green, blue and solar-panel black.

All are green in one sense. In different ways, each helps to solve serious environmental problems. One issue is air pollution, which needs no introduction.The second is the urban heat island. Because cities have lots of dark surfaces that absorb heat and relatively little green cover, they tend to be hotter than surrounding areas — the average summer temperature in New York City is more than 7 degrees hotter than in the Westchester suburbs. 

The other problem is storm water runoff. In New York, as in about a fifth of American cities, there is only one sewer system to conduct both rainwater and wastewater. About every other rainfall in New York, sewers flood and back up, discharging their mix of rainwater and wastewater into the city’s waterways, which could be alleviated by the addition of vegetated roof systems to absorb rainwater...
