This narrow angular treehouse in Brisbane, Australia , captures the freedom and beauty of the outdoor-indoor lifestyle. The Taringa Treehouse, designed by Phorm Architecture + Design , is nestled under a large tree and houses a study, bedroom and a climbing wall. The entire main floor can be opened up to the exterior via sliding glass walls. The building is detached from the main residence and occupies a cozy spot under an existing tree in the backyard of the property. It’s wedge-like form points toward the residence, with its wider side facing out into the yard. A ground floor patio with a climbing wall is located at the tip of the two-story structure and opens up toward the garden via large sliding glass walls.

The treehouse is devised as an invitation to visit and engage with this distinct yet typically unchartered territory,” said Paul Hotston of Brisbane-based Phorm Architecture + Design. Weatherboard covers the garden-facing elevation, while metal cladding dominates the western facade which creates a contrast with the verdant surroundings. The shape and materials of the house are inspired by traditional local architecture , translated into a modern-day t reehouse that’s playful and fun. + Phorm Architecture + Design Via Dezeen

New super concrete makes buildings strong enough to withstand magnitude 9 earthquakes

Recent natural disasters such as hurricanes in the Caribbean and earthquakes in Mexico have laid bare the need for more resilient buildings. Fortunately, researchers at the University of British Columbia (UBC) have developed a sprayable, eco-friendly concrete that makes the exterior of buildings as strong as steel and able to withstand unforeseen disasters . The material is called Eco-friendly Ductile Cementitious Composite, or EDCC – and it’s is predominantly comprised of an industrial by-product called fly ash. Said UBC Professor Nemy Banthia, “The cement industry produces close to seven percent of global greenhouse gas emissions. By replacing nearly 70 percent of cement with fly ash, we can reduce the amount of cement used. This is quite an urgent requirement, as one tonne of cement production releases almost a tonne of carbon dioxide into the atmosphere.” The final product is very similar to steel. It is durable, malleable and much more ductile than ordinary concrete. To test the invention, researchers sprayed EDCC on concrete block walls about 10 mm (one-half inch) thick. They then simulated a magnitude 9 earthquake — the same strength of the earthquake that rocked Tohoku, Japan, in 2011. “The results of these tests have been amazing,” said UBC engineering Ph.D. candidate Salman Soleimani-Dashtaki. “We can shake the wall extensively without it failing.” The video above shows that the unreinforced wall collapsed at about 65 percent intensity. In contrast, the reinforced wall withstood full intensity shaking and flexing. “A 10 millimeter-thick layer of EDCC … is sufficient to reinforce most interior walls against seismic shocks ,” said Soleimani-Dashtaki. EDCC is already on the market – in British Columbia, Canada , the product has been designated as “an official retrofit option.” The product is growing in popularity, as it is more cost-effective than major structural renovations or the steel bracings often required for earthquake protection. Plans are already in motion to reinforce the walls of an elementary school in Vancouver, B.C., and to upgrade a school in the seismically active area of northern India . With this technology, the costs of retrofitting buildings is cut in half. Said Banthia, “This can be very easily scaled to other projects. It costs about half of what other retrofit strategies would cost.” Via Metro News Canada , Engadget Images via UBC Civil Engineering Department, Pixabay, YouTube

For Sprint, communications is core to climate resilience

Comments Off on For Sprint, communications is core to climate resilience

For Sprint, communications is core to climate resilience Ann Goodman 8:45am Featured Image:  In what surely is a glaring understatement, Tanya Jones, manager of Sprint Corp.’s vital Emergency Response Team Operations, observed, “We learned quite a bit from Hurricane Sandy .” Indeed, Sprint, like all telecommunications carriers, lost cell sites on the northeastern seaboard and in New York City in the 2012 superstorm, which hurt its cellular operations. Fortunately, Sprint’s ERT was able to provide critical communications services to various first responders and emergency agencies using vehicles such as COWS (Cell On Wheels) and COLTS (Cell on Light Trucks), including those near the World Trade Center in New York, where the vehicles were parked right in front of the Freedom Tower, after police blocked it off for the Sprint workers. Among the key learnings from the debacle, said Jones: How better to rebuild; where better to stage; how better to “future-proof our technology to ensure our equipment is upgraded and our personnel equipped” for disaster. Her team of disaster emergency workers in multiple U.S. locations, including Dallas and Sterling, Va., is at the center — and on the front lines — of Sprint’s emerging approach to climate resilience. Having overseen the company’s disaster response for 10 years and found herself on the spot during 2,500 events — from hurricanes to fires to tornados to floods — her interpretation of such events is telling: “While a disaster is a disaster, I subscribe to the theory that the climate is changing weather patterns. You see more forest fires in the west and more hurricanes; you see increased water and air temperatures and storm activities; and there’s been an uptick in severity of storms,” Jones said. A communications approach to resilience Jones’ thoughts on disaster and climate echo the observation of Sprint’s director of corporate responsibility and sustainability, Amy Hargroves , who heads the company’s approach to climate resilience: “The same risks exist for climate-related events as for other disasters, but there’s a greater range of events and more of them.” Of acute importance, Hargroves noted: “In our field, as a communications company, disaster resilience has to be core to our business, because there’s so much dependence nationally on communications.” Indeed, while now majority owned by Japanese parent Softbank, Sprint’s network is United States-centric, serving federal, state and local governments as well as emergency responders — and, of course, the company’s 50 million-plus business and individual customers. Because emergency response is at the core of Sprint’s resilience approach, the company is always at the cutting edge of communications technology: “LTE, high-speed data, 4G, emergency response — we can provide that now, but most of what we do is make sure we’re on top of technology, because it’s not if but when a disaster will happen,” Jones explained. Keeping its emergency response team up to date with special equipment and mobile communications — as well as learning from each disaster — is only one part of Sprint’s four-pronged approach to implementing climate resilience, a business priority of Hargroves’ sustainability team, which has won the company a number of accolades, including the recent Compass Intelligence Eco-Focus and EPA Climate Leadership awards. Other priorities in Sprint’s resilience approach include: • Frequent assessments of the company’s network risks. • Improving backup power with less carbon-intensive sources, including research on hydrogen-fuel cells, in part with the Department of Energy. • Reviewing lessons learned to find new business opportunities, including those related to customer offerings. Overarching goals include reducing the company’s greenhouse gas emissions and electricity use by 20 percent by 2017 from 10 years earlier and ensuring 90 percent of its supply chain meets Sprint’s environmental and social criteria. The goals are complementary, particularly given Sprint’s massive network overhaul, at a cost of nearly $5 billion over three years, now coming to an end. That renewal has allowed Sprint to achieve its 2017 GHG reduction goal and come within 1 percent of its electricity reduction goal. Sprint provided free guidance on greenhouse gas measurement, reporting and reduction strategies to its top suppliers, including those involved in the network overhaul. Network risks: cell sites, signaling, fleets, response prioritization To ensure the network stays up to date — and up and running — in case of disaster, the company runs quarterly risk assessments. And Sprint expects more extreme events. On planning for potential climate risks, Hargraves noted that since Sandy, “it’s not so much that we’ve done anything new, but that there’s increased risk recognized through insurance [coverage] and assessment. That’s how we adjust and plan.” Fleets: Network risks also include the company’s fleet of vehicles for a range of conditions that could affect the cell sites, the most vulnerable part of the network. Fortunately, Hargroves noted, insurance companies have been building climate risk into their corporate risk models, assessing the level and nature of risk per site. With that information, Sprint can determine which sites may be most vulnerable and potential candidates for relocation. “We look at 500-year flood levels when we build our sites,” she said. Cell sites: With some 55,000 cell sites across the country, Sprint has a lot to keep track of. The signal from the site must be accessible in order for wireless customers to complete calls. Cell site traffic is aggregated at over 100 major satellite switching sites that allow calls to be terminated between various wireless and wire-line networks. Much of the IP-based (Internet Protocol) control functionality is handled by some 30 Core sites that act as traffic directors for voice and data services. “Networks are complicated beasts, and risk varies according to the site,” said Hargroves. “But the most important parts to protect are the switch sites, mainly because they aggregate traffic from thousands of cell sites. A single switch outage can isolate a complete market, leaving customers without critical wireless services over a large geographical area.” Emergency response: Of rising importance to the company’s resilience plan, said Hargroves, is the sort of emergency response to disasters that Jones manages. “We anticipate greater demand for the services of our Emergency Response Team because of the increase in the number of disruptive events,” Hargroves said. Essential to the response is the specialized mobile equipment, such as mobile communications centers, including COWs and  COLTs . These are whole vans or trailers especially useful in places that are hard to access. “Demand for COWs and COLTs has increased over the past several years, so our fleet has been [growing] and is expected to continue to grow in response,” she explained. A big part of emergency response is sequencing and prioritization: That entails determining who is “in charge” of disaster management (from a government perspective), which communications capabilities are intact and which are needed — and then developing a prioritized list of communications services and infrastructure that the company will provide. Sprint may send out its ERT to work with government and provide critical communications services initially for the first responders — government personnel, military, FEMA, Red Cross — to enable them to communicate, especially if a lot of infrastructure, such as cell site towers, signal repeaters or switching centers, has been disabled. The Sprint ERT always works with local government, including sheriffs and firefighters. Next in line are customers. Risk, site planning and backup power: response to storms, fires, flooding While Sprint always has had backup power initiatives, those have expanded throughout the United States over the past few years — as has the need for backup, which has risen, along with the frequency of disasters. “Provision of backup power is very much motivated by both natural and manmade disasters,” said John Holmes, who, as Sprint’s manager of network planning, is responsible for the company’s strategic planning efforts involving backup power, energy efficiency and sustainability for the company’s network. The need for backup power varies by region. “In the eastern and southern coastal regions, hurricanes and tropical storms can cause widespread damage,” he said. “In the Midwest and upper Midwest, ice storms can result in widespread outages. “Wildfires can be a problem anywhere there’s a combination of very dry weather and a lot of combustible ground or tree cover. As a general rule, they are more frequent out west. Places like California or the Pacific Northwest are susceptible to earthquakes. “Also, don’t count out tornadoes. Heavy rainfall can result in flooding, and many times that will occur downstream of where the majority of the rainfall occurred.” Sometimes the power stays on, but Sprint “can still have widespread outages, if, say, a major backbone fiber carrying multiple backhaul circuits (which connect the BTS equipment to the switches) is cut,” Holmes pointed out. “That would prevent calls from being completed … and is often manifested to the wireless subscriber as a fast busy signal.” What’s more, Hargroves added, the question of where to build cell sites has been complicated in recent years by the increase in frequency and severity of storms, as well as the availability of energy and water sources. “A few years ago, we studied the impact of climate change on water scarcity and cost in the U.S. The results were shared with the C-suite and operational teams so they could use it as input for site planning. For instance, if you need a big building, you should expect it to have a water chilling system, which is a big driver of water use. If you know where water will be scarcer, and thus more expensive, you should avoid building in those areas,” Hargroves explained. In 2013, water cost the company a mere $1.2 million, compared with $300 million for energy, “so it’s a far lower economic priority,” she said. “However, given the importance of water globally, it would be foolish not to consider drought forecasts in your site-planning process.” By contrast, Sprint has a strong economic incentive to reduce its energy usage, which is primarily electric. The company has cut its internal electricity use by 22 percent since 2007 and reduced its electricity costs by $87 million annually. Including Clearwire, acquired — along with its emissions output — in 2013, Sprint’s electricity costs are still down by 19 percent. Power backup and hydrogen fuel cells When disaster strikes, electrical power from traditional sources is likely to go down, as recent climate-related events, including Superstorm Sandy, have shown. That’s why backup power is essential for telecommunications providers such as Sprint. A backup plan is needed for all critical components in the network. Because Sprint is committed to lowering carbon emissions, the company looks to cleaner backup power sources. “Our second priority for carbon reduction is back-up power, which is a leading contributor to Sprint’s Scope 1, or direct, emissions,” said Hargroves. “Scope 1 emissions represent only 3.5 percent of our aggregate Scope 1 and 2 emissions. Within the 3.5 percent, 10 percent is emissions from back-up power sources, such as diesel fuel and propane. “Sprint includes its Scope 1 emissions in its goal to absolutely reduce GHG emissions by 20 percent by 2017, and in fact, has reduced them by more than 41 percent so far. Increasing our use of hydrogen fuel cells and propane — and decreasing use of diesel generators — as backup power sources at cell sites has contributed to this success.” Hargroves noted that Sprint’s fleet, with 1,000 vehicles, has a substantially smaller GHG footprint than the fleets of its direct competitors, which have 40,000 or more vehicles. “When we talk about network resiliency, we mean the ability of the network to maintain power and functionality, particularly at the switching and cell site level,” she said. “There are multiple lines of defense, the first of which is batteries. Since we have the greatest dependency on batteries, much of our focus is on reducing the environmental impact and duration of use of our network batteries. We have partnered with the National Renewable Energy Lab and the Department of Energy on battery technology, which is so critical for a communications company.” The second line of defense is using both a diesel generator and natural gas feeds, even propane and methanol, to access multiple core electricity streams in a single place to provide backup power. While solar and wind power are sparsely used where possible, neither technology is practical, given risks (when wind is strong, a disaster could be in the making), lack of continuous availability of energy and cost-benefit balance. Sprint is maximizing its use of hydrogen fuel cells in part through work with the DOE, whose $7.3 million grant in 2009 has supported the company’s development and deployment of 260 additional fuel cells to support its backup power systems, network planning manager Holmes said. The innovative fuel cells use an on-site, refillable, medium-pressure hydrogen storage system, which has eliminated bottle swaps, required in earlier generations of the technology, while boosting the standby runtime of the cells to parity with that of other backup solutions such as diesel generators. The company’s 500-plus hydrogen fuel cells help Sprint ensure that its Scope 1 emissions related to back-up power stay low despite significant increases in network resilience, achieved via more sites with longer back-up power. Customers and business opportunity Perhaps the biggest business opportunity in climate resilience for the company is on the consumer side of the business, said Hargroves. “We’re trying to identify additional services we can provide to help customers” understand and prepare for potentially disruptive events. So far, most of the company’s focus has been on the “survivability of network infrastructure,” Hargroves said. The company’s Japanese parent Softbank has exceptional experience in this arena, gained during the Great East Japan earthquake of March 2011. Explained Hargroves: “Up to now, the main things we’ve done involve the survivability of our services, directly helping first responders, supporting customers on billing, and managing our service, versus providing information that can help them manage through the disaster — things like how to extend the life of your phone battery and recharge with limited electricity sources available, which is different from relaying information during a disaster, as people become more and more dependent on cell service.” But the company imagines the opportunity to change that. Sprint may have a competitive advantage in consumer engagement, if it can leverage some other assets of Softbank such as Yahoo (in Japan) and provide disaster-related content on its customers’ phones. She added: “We do think there are some interesting opportunities with emergency alert systems and disaster content support. So if someone can figure out a good way to do it, this is a terrific opportunity.” Top image of Sprint store in New York City by  Northfoto  via Shutterstock Topics:  Climate Computers Fleets

Comments Off on Thank You Nelson Rolihlahla Mandela and Rest in Peace

When Nelson Rolihlahla Mandela was inaugurated in Pretoria on 10 May, 1994, I distinctly remember wondering what would happen to South Africa , where I spent my childhood. By then, I was finishing high school in Virginia, where my peers often asked me about apartheid and the systemic racism that marred our otherwise beautiful nation. When he became president, Madiba had every reason to exact a terrible revenge on behalf of his people. And no doubt those who had suffered so gravely at the hands of white supremacists wanted him to take a retaliatory stance. Instead, he led a deeply scarred nation through reconciliation, showing a generosity of spirit never before seen in an African leader. All of this after spending nearly three decades behind bars. Upon hearing the news of his passing, my first reaction was relief. He had a long life, 95 years full of strife, and the current leadership has disgraced his extraordinary sacrifices with corruption and petty politics. But mostly I feel an incredible sadness, as though my own grandfather has died. Madiba made me want to be a better person; it is he who taught me to be kind and tolerant, to treat all people equally, to live a free life with respect for the freedom of all other living beings. I’m not even half the person he was. But I can try. We can all try. We owe him that. + Nelson Mandela Foundation + South African Government Homepage Permalink | Add to del.icio.us | digg Post tags: Inhabitat Mandela tribute , Madiba , Mandela father of south africa , Nelson Mandela , nelson mandela foundation , Nelson Mandela has died , nelson mandela information , RIP Nelson Mandela , South Africa Apartheid , South Africa reconciliation , south african childhood , south african government website , Tafline Laylin Nelson Mandela tribute , Tata Mandela
