5 May 2011 President Jacob Zuma gave the promotion of South Africa’s burgeoning tourism industry a boost by signing “The Golden Book”, a campaign by global tourism pacesetters, on the sidelines of the World Economic Forum on Africa in Cape Town on Wednesday. Zuma became the first African head of state to make an entry in the book, which is a joint initiative by the UN World Tourism Organisation (UNWTO) and the World Travel and Tourism Council (WTTC) to position travel and tourism higher in the global agenda. The campaign seeks to mobilise recognition and support for travel and tourism from world leaders by demonstrating its crucial role in economic growth, job creation and development. “We take tourism very seriously in this country, given its job creation potential,” Zuma said. “That is why we have identified tourism as one of the six job drivers in our New Growth Path framework. “Tourism’s contribution to the GDP of our economy has increased from just less than five percent in 1994 to an estimated 7.7 percent in 2010.” Zuma said the country’s tourism sector was well placed to address unemployment “given its labour-intensive nature.” The President said tourism jobs were not only created in the travel and tourism industry, but also in the manufacturing, financial services, agriculture, healthcare and others areas of the economy. South Africa aims to increase the number of foreign arrivals from 7-million in 2009 to 15-million by 2020. “We plan to increase tourism’s total contribution to the economy from R189-billion in 2009 to R499-billion by 2020,” Zuma said. “Most importantly, we want to create 325 000 new tourism jobs by 2020. We will do everything possible to promote and grow the tourism sector so that we can achieve these developmental goals.” Among those who attended the signing ceremony were WTTC President David Scowsill, UNWTO ethics committee president Dawid de Villiers, and Tourism Minister Marthinus van Schalkwyk. The signing took place on the sidelines of the World Economic Forum on Africa conference being held at the Cape Town International Convention Centre. Source: BuaNews

RELATED CONTENT With any house, there are so many variables that influence the decision to choose one particular mechanical system over another: climate, house size, cost, local availability and cost of fuels and materials, and the lifestyle and preferences of the occupants. There is no “one-size-fits-all” system that we can reliably prescribe for all projects. Phil and I sat down over a good winter cocktail to share our views, anecdotes, battle scars, and wisdom on this important subject.The Highlights:The Bobby Burns Cocktail: “We’ll tak a cup o’ kindness yet for auld lang syne.”Demand: Let demand be your guide. After climate, the peak load demand of your home is probably the most important thing to understand and define. (This means you’ll have to perform some energy modeling or at least a heat-loss calculation.) The chart developed by the Portland Building Science Discussion Group should help you identify the systems to consider.Climate impact: Let your conscience be your guide. For some people, it’s not all about cost efficiency. It’s also about limiting emissions and the ecological footprint of the system itself. You may rule out oil and propane altogether. PODCAST: Ground-Source Heat Pumps, Part 1PODCAST: Biomass BoilersGBA Encyclopedia: Green Heating OptionsHeating a Tight, Well-Insulated HouseAir-Source or Ground-Source Heat Pump?Ground-Source Heat PumpsRadiant-Floor HeatingIs Radiant Floor Heat Really the Best Option?Heating Options for a Small HomeA ‘Magic Box’ For Your Passivhaus TRANSCRIPTChris: Hey, everybody, welcome to the Green Architects’ Lounge podcast. I’m your host, Chris Briley.Phil: And I’m your host, Phil Kaplan.Chris: We should start with an apology. Hey, everybody, sorry — we haven’t been recording much.Phil: We’re going to pretend that people have been missing us?Chris: Yeah. Sorry, folks. Today we’re doing how to choose a mechanical system. This is a conversation we have a lot with our clients. They want to know what the best one is for their house.Phil: And there is a logical way to choose one. Chris and I have our systems — they’re not foolproof — but we’ve talked to some smart people and we’ll talk you through it.[The guys jaw about Chris’s new partnership with Harry Hepburn, the possibility of having Bill McKibben on a future podcast, the NESEA conference, and this episode’s cocktail, the Bobby Burns.]Phil: So how do we start choosing a mechanical system?Chris: Let’s start with a chart. Imagine a building science discussion group filled with architects, raters, and builders. When asked to choose a mechanical system, each person chimes in with the best one. If you get anything from this podcast, it’s that there is no one solution.Phil: Logic is only a small part of choosing a mechanical system.Chris: “If that, then this” just doesn’t happen. So the building science discussion group decides to make this chart that shows when we consider the different systems based on the peak heating load — we’ve divided it up into 0 to 25,000 Btu, 25 to 50,000 Btu, 50 to 75,000 Btu, 75 to 100,000 Btu, and 100,000 and over — there are certain systems you look at, depending on peak heating load. Ductless minisplits for 0 to 25,000 Btu are a great choice. If it’s 75,000 or more, possibly you’d consider ground-source heat pumps. The chart has solar thermal, a woodstove for point-source heating — so you’d have to design for this one source of heat.Phil: An open plan, compact.Chris: And the downstairs communicates with the upstairs thermally. You’ve also got air-source heat pumps, which are fantastic for the lighter loads, and electric in general — electric boilers, baseboards — and of course, oil and gas boilers and furnaces.I was talking to Marc Rosenbaum today, a mechanical engineer at South Mountain, and asked him how he chooses a mechanical system. Now that climate change has entered the conversation and has become a priority, let’s get away from fossil fuels. So, for Marc, it’s either electric or biomass. It’s a matter of heat load. If the heat load is rather high, 50,000 or more Btu, you’re looking at biomass. But some people may not want to schlep logs of wood to their wood boiler of woodstove, or they may not want to deal with pellets, which may not be available in their area. With lighter heating loads, you’re looking at electrical heat pumps — ground-source heat pumps or air-source heat pumps.Phil: So, that’s it, we’re done! Cheers!Chris: Well, with the ductless minisplits, it’s easy to take care of a lighter load house. Martin Holladay had a fantastic article in Fine Homebuilding.Phil: Heating Options for a Small Home.Chris: We recommend that everyone read that. It also covers the system in a passive house — UltimateAir has a combination unit.Phil: A hot water coil off the ERV.Chris: We’ve talked about a cold water coil for cooling. The thing is to trick the ERV into activating when there’s a demand for heating or cooling, not just fresh air.Phil: We’re talking about a really low heating load: 10,000 Btu or even lower.Marc has his ideas of what’s important, and so do we. Marc does not believe in sacrificing energy for looks. Aesthetics are important to architects in a different way than to engineers.Chris: Clients are the same way. If they walk by a ductless minisplit cassette and think, “I hate that thing, the way it sits there on the wall and mocks me,” then it’s not worth it; it’s not going to work.Phil: We all decide what’s most important for us.Chris: Clients might just be looking at operation costs. They’re not trying to save the planet; they’re trying to save money. They’re trying to be the smartest kids on the block and have a really efficient house.OK, Phil, let’s say a client comes to you and says, “I want a ground-source heat pump.”Phil: Let’s go through the logical reasons about why we don’t use them. And the client says, “Yeah yeah yeah, but I still want one.”Chris: And it’s not out of the question, but the conditions have to be right for that to be a smart choice. That does happen, but increasingly less.Phil: We had another client who wanted electric baseboard. And it wasn’t a passive house. Close to it, but…Chris: Just electric baseboard?Phil: Just electric baseboard because they wanted a silent system. They were going to buy enough PV to offset it. But it wasn’t a great idea in terms of energy use.Chris: I’ll share a battle scar. In the Redfern house — a little LEED Platinum house with 40 grand of hardware on the roof in PVs and solar thermal, and demand is really, really low — we cheaped out on an electric boiler. It’s a hot water heater, essentially, for the boiler. It really bothered me. Why at that last moment did we cheap out? I understand the economics. It’s really not going to be on that often. It’ll be offset by solar. But we could have put three more panels on to get to net-zero.Phil: Remember, panels were a lot more expensive then — 8 or 9 grand per kilowatt. It’s less than half that now.Chris: Well, we could have gone with one ductless minisplit and spent only a couple thousand more than with this electric boiler. And yeah, if you compared the two, would the minisplit ultimately have paid for itself based on how little it would be used? But the efficiency of it would have been worth it for the planet. To go that far and then cheap out… But the happy ending is there’s now a woodstove in the house and the boiler never comes on.Phil: So one of the things that bothers you about a house is the climate damage, the CO2.Chris: That’s a big part of the metric.Phil: But for some people, number 1 is cost. That’s always a conversation.Chris: That’s right. You did this passive house for $135 per square foot, and still people said, “My God, that’s expensive for a little house.” We’re competing with houses already on the market.Phil: If we can reduce the cost of mechanical systems, we can put the extra dollars into the envelope. At 15,000 Btu, you can get yourself an HRV and a pre-heater. Eight to ten grand for that system; that’s pretty awesome. If the Btu go up to 25 to 30,000, can we stay below 10 grand?Chris: That’s really hard. You need something in there to handle the load. A ductless minisplit.Phil: Minisplits work even when it’s 0 degrees outside. If you’re real disciplined and have a tight, compact house, you could do it. It would be ductless and cost 9 to 12 grand. That’s assuming you have an electric resistance water heater.Chris: What if I’ve got natural gas right out there on the street?Phil: A combo hot water tank and air handler — a ducted system, but the gas is right there. Ten to 12 grand. When would you use a hot water heat pump? Probably around loads of 50,000 or more.At fairly low loads, if aesthetics are important, you go to ducted minisplits. You’re adding a good 10 grand, maybe not that much. People spend a lot of money on pretty. Minisplits still stay off of fossil fuels, which is nice.Chris: What if my house is way bigger?Phil: Then you go to the gas boiler. It’s still not a bad system when you have a big house that’s an energy guzzler.Chris: The gas boiler can be 94 to 98 percent efficient. And still cleaner than oil.Phil: In the higher loads, wood pellet boilers make sense. Ground-source heat pumps.Chris: They’re still there.Phil: We didn’t talk about radiant.Chris: The more robust the envelope gets, the more costly the radiant system — the hundreds of feet of tubing, the circulator pumps in every zone, the computer components to monitor things…Phil: A complex system, locked in concrete.Chris: You’re talking about a $25,000 system, depending on the load and the size of the house. You’re talking about buying a lot of hardware for radiant floors. And if your house is really well insulated and the demand is so low — let’s say 15,000 Btu — then you have a boiler pushing fluids through a slab…Phil: They break all the time. And it’s rarely going to get the call.Chris: If the computer component is smart enough, it’s tweaked the temperature to be in the comfort zone, which is below your body temperature.Phil: And then it’s going to be cold underfoot.Chris: Or not warm. You won’t even notice it’s on. But if you have a really leaky house, radiant might be a great system.Phil: It comes down to what’s important to you. We advocate staying off fossil fuels, keeping loads down real low, keeping it simple.Chris: We’re trying to get rid of this component.Phil: The best mechanical contractors try really hard not to take your money.OK, time for a 6-digit idea: the Magic Box. It’s a combination appliance with an HRV, a heat pump and a water heater. Zehnder makes them. But we can’t get them here yet.Chris: What about the Lunos? They look like dryer vent type penetrations. It’s a way to handle the ERV without an ERV. It’s two holes in the building with ceramic filters in them. The filter is the temperature of the air. One opens up and breathes in. Then the other hole in the wall lets the breath out.The better our buildings get, the more we need better and better technologies to run those better buildings.[The episode closes with A.C. Newman’s song “I’m Not Talking.”] Cost: Then, of course, there’s the cost of the system to consider. In the podcast, I mention the statistic that for most buildings (not just houses), the initial construction cost represents only 11% of the building’s total cost. I had a chance to chase down where the statistic is from: Solutions for Energy Security & Facility Management Challenges by the Association of Energy Engineers. (By the way, the calculation only considers operating costs for the first 40 years.)That makes the efficiency of your system highly important. But the consideration of the initial cost is an inescapable reality. To help with this, we’ve provided a chart that shares some rule-of-thumb numbers for the systems mentioned. Of course, costs vary widely among different regions and installers. With time, this chart will become meaningless as the market changes.Cost offsets: Remember, the goal here is to shrink the mechanical system in order to save money to offset the added cost of building a robust envelope.GSHPs and radiant floors: Do they still make sense? Sometimes, maybe.Six-digit idea: Let’s start importing (or better yet, manufacturing) the Magic Box here in the States.Hot Zigg!: The Lunos e2 looks like a cool product that is approaching active ventilation in a whole new way. This is not an endorsement, as Phil and I haven’t used them yet, but something we’re keen to explore.Phil’s pick: The song of the episode is “I’m Not Talking” by A.C. Newman. It’s a great album for the studio.Don’t forget to register and attend Building Energy 13, a conference hosted by NESEA. Phil and I will be leading a Sprout Follies session in the Fundamentals Track on Thursday, March 7th at 2:00.Thanks for listening. Cheers.

Man City boss Guardiola confident Fernandinho can make Liverpool clashby Paul Vegas10 months agoSend to a friendShare the loveManchester City boss Pep Guardiola is confident Fernandinho can make their clash with Liverpool.The influential midfielder has missed the last three matches through injury – which has coincided with City losing two times.And Guardiola has revealed the 33-year-old has made a return to training – even though he is still short of full match fitness.Asked directly about Fernandinho’s fitness Guardiola said: “Almost everyone is fit. They are training – not 100 per cent but training.”We will have his qualities again and he is an incredible player. He is so important like Kevin is, so of course we have to find another solution if he is not available.” About the authorPaul VegasShare the loveHave your say

DUBAI, United Arab Emirates – High above Yemen’s rebel-held city of Hodeida, a drone controlled by Emirati forces hovered as an SUV carrying a top Shiite Houthi rebel official turned onto a small street and stopped, waiting for another vehicle in its convoy to catch up.Seconds later, the SUV exploded in flames, killing Saleh al-Samad, a top political figure.The drone that fired that missile in April was not one of the many American aircraft that have been buzzing across the skies of Yemen, Iraq and Afghanistan since Sept. 11, 2001. It was Chinese.Across the Middle East, countries locked out of purchasing U.S.-made drones due to rules over excessive civilian casualties are being wooed by Chinese arms dealers, who are world’s main distributor of armed drones.“The Chinese product now doesn’t lack technology, it only lacks market share,” said Song Zhongping, a Chinese military analyst and former lecturer at the People’s Liberation Army Rocket Force University of Engineering. “And the United States restricting its arms exports is precisely what gives China a great opportunity.”The sales are helping expand Chinese influence across a region vital to American security interests.“It’s a hedging strategy and the Chinese will look to benefit from that,” said Douglas Barrie, an airpower specialist at the International Institute for Strategic Studies. “I think the Chinese are far less liable to be swayed by concerns over civilian casualties,” he said.At the start of the year, a satellite passing over southern Saudi Arabia photographed U.S.-made surveillance drones at an airfield, alongside Chinese-manufactured armed ones.According to the Center for the Study of the Drone at New York’s Bard College, that was the first documented example of the two drone systems being used in the war in Yemen. The country has emerged as a “sort of a testing ground for these strike-capable drones,” said Dan Gettinger, the co-director of the Center for the Study of the Drone. “There’s a rapid turnaround from delivery to deployment.”U.S. drones were first used in Yemen to kill suspected al-Qaida militants in 2002.One of the biggest Chinese exports is the Cai-Hong, or Rainbow, series made by the state-owned China Aerospace Science and Technology Corp., or CASC, the largest contractor for the Chinese space program.CASC’s CH-4 and CH-5 models are on a par with San Diego-based General Atomics’ Predator and Reaper drones, and much cheaper. Independent analysts say the Chinese models lag behind their American counterparts but the technology is good enough to justify the price tag, which might be half or less.A CASC executive, who spoke on condition of anonymity because he was not authorized to talk to journalists, said cutting-edge U.S. models like Boeing Co.’s Stingray, introduced this year for the U.S. Navy, still hold a technological advantage.And while price is an advantage, so too is a more relaxed attitude toward how drones are used, said Ulrike Franke, an expert on drones and policy fellow at the European Council on Foreign RelationsSince 2014, China has sold more than 30 CH-4’s to countries including Saudi Arabia and Iraq in deals worth over $700 million, according to CASC. Ten countries are currently in negotiations to purchase the CH-4, according to the firm.Last year, China sold to the UAE the Wing Loong II, an armed unmanned aerial vehicle roughly equivalent to the American MQ-9 Reaper.“In recent years, all types of drones have proven their value and importance through a high degree of use in warfare, and the military has noticed,” said the top CASC executive. “Many countries are now speeding up the development for these weapons systems, including China.”During President Xi Jinping’s five years in power, China has stepped up spending on stealth fighters and aircraft carriers for its own military, while boosting sales of advanced equipment such as attack submarines to close allies like Pakistan.China still lags behind the U.S., Russia, France, and Germany in total arms sales but it’s catching up. Chinese arms exports rose by 38 per cent between 2008-12 and 2013-17, according to the Stockholm International Peace Research Institute, which tracks the global arms trade.Mounting criticism over the rising civilian death toll in Yemen prompted the U.S. to impose restrictions on drone sales, forcing foreign countries to go through the U.S. government to buy armed drones, including those with laser-guidance systems.The Washington-based New America Foundation estimates more than 240 drone strikes in Yemen have killed more than 1,300 people, including at least 111 civilians.But with China’s drone sales booming, there’s growing pressure from U.S. arms makers to remove restrictions to let them catch up.After some U.S. lawmakers urged President Donald Trump to loosen controls and let General Atomics sell its armed Reapers to Jordan and the UAE, the administration on April 19 permitted U.S. manufacturers to directly market and sell drones, including armed versions.The government must still approve and license the sales, which are also contingent on human rights and proliferation reviews and congressional authorization.General Atomics did not respond to a request for comment.China doesn’t routinely announce arms sales like the U.S. and others, but a review of drone spottings gives some indication of who its customers are.— In Iraq in October 2015, the country’s then-defence minister inspected a CH-4 drone at an air base in the city of Kut.— Chinese armed drones have been operating at Jordan’s Zarqa Airport, at an air base in Pakistan and from bases in Egypt in the Sinai Peninsula and near its border with Libya, according to satellite photos analyzed by the Center for the Study of the Drone.— Satellite photographs taken of a mysterious air base in the United Arab Emirates’ deep south — a desert area known as the Empty Quarter — appear to show three Wing Loong IIs, IHS Jane’s Defence Weekly reported in January.— Two CH-4s were spotted by satellite alongside surveillance-only Predators purchased by the UAE at Jizan Regional Airport in southern Saudi Arabia, near the kingdom’s border with Yemen, according to the Center for the Study of the Drone.— Outside of the Mideast, Nigeria has used Chinese armed drones against the Islamic extremist group Boko Haram.___Shih reported from Beijing.
GREELEY, Colo. — The U.S. branch of the world’s largest meat producer will pay $4 million in back wages and other monetary relief as part of a consent decree settling allegations by federal labour officials.The Greeley Tribune reports the U.S. Department of Labor claimed in two actions that JBS USA discriminated based on race and gender against applicants for labourer positions at its facilities in Hyrum, Utah, and Cactus, Texas.The company with U.S. headquarters in Greeley, Colorado, has agreed to pay 12,625 class members at those facilities and hire 1,664 of the applicants.It has also agreed to retain an independent workplace consultant to review and revise its hiring process.Spokesman Cameron Bruett says in a statement JBS USA denies the allegations, but it believes “more can be accomplished through partnership.”___Information from: The Tribune of Greeley, Co, http://greeleytribune.comThe Associated Press
