The new ministers were sworn in on 10 July.“Twenty years of democracy have changed the face of our country,” said Zuma, making the announcement. “To take that change forward, I have decided to make some changes to the national executive.”This is the fourth reshuffle in as many years, and unlike the previous occasions, Zuma has declined to give reasons for the move – analysts say in doing so, he has missed an opportunity to take the nation into his confidence.However, they have lauded the appointment of the three new ministers, as all are individuals who have exemplary records of service and have shown strong commitment to the welfare of the country. Comments have also shown confidence in their ability to carry out their duties in a more efficient way than their respective predecessors.The new appointees are as follows:Minister of co-operative governance and traditional affairs, Lechesa Tsenoli,Minister of human settlements, Connie September,Minister of communications , Yunus Carrim,Minister of energy, Ben Martins,Minister of transport, Dipuo Peters,Deputy minister of justice and constitutional development, John Jeffery,Deputy minister of science and technology, Michael Masutha,Deputy minister of co-operative governance and traditional affairs, Andries Nel,Deputy minister of rural development and land reform, Pamela Tshwete.Of the nine appointments, four are sideways moves and five are promotions. Analysts and opposition parties have noted that none of them pose any political threat to the president, and that other ministers who have been under-performing retained their positions, meaning that Zuma did not fully address all the problems that exist at the moment.“Focus must remain on consolidating the effectiveness of governance and meeting the needs of our people, the majority of whom are working class and poor,” the South African Communist Party said in a statement, congratulating its members Carrim and Tsenoli – who both sit on the central committee – on their achievement.Meanwhile, the board of the South African National Roads Agency has wished former transport minister Ben Martins well in his new position as energy minister, and welcomed his predecessor Dipuo Peters as the new minister of transport. As these two ministers have performed relatively well, the reason for their redeployment is unclear.The Democratic Alliance has voiced its approval of Tsenoli’s appointment, urging the new minister to focus on issuing regulations that will prescribe minimum qualifications and skills for municipal managers.Our new cabinet ministersBut who are these new – or not-so-new, in some cases – leaders who have been tasked with taking our country forward?Lechesa Tsenoli: Solomon Lechesa Tsenoli is the former deputy minister for rural development and land reform. He has years of experience in dealing with local government matters, and replaces Richard Baloyi.He has a certificate in adult education from the University of KwaZulu-Natal, a certificate in development planning for community leaders from the University of the Witwatersrand, and a certificate in public policy management from the University of Western Cape.Between 2004 and 2011 he served as the chairperson of Parliament’s portfolio committee on co-operative governance and traditional affairs.He has been a member of numerous bodies and organisations, including the National Housing Finance Corporation, the Institute for Local Government Management, and the Joint Rent Action Committee, and is a founder member and former president of the South African National Civic Organisation.Tsenoli is also a student leadership, organisational and life coach.He has been replaced by Pamela Tshwete, the widow of former safety and security minister Steve Tshwete, who passed away in 2002 of complications related to a recurring backache followed by pneumonia. Pamela Tshwete is a member of the national executive committee of the African National Congress Women’s League.Connie September: Cornelia “Connie” September is the new minister of human settlements. She replaces Tokyo Sexwale, who was the first premier of Gauteng province.September is a former deputy president of the Congress of South African Trade Unions, and was the national treasurer of the Southern African Clothing and Textile Workers Union.She is a member of the portfolio committee on trade and industry, and chairs the portfolio committee on water affairs and forestry. She holds a master’s degree in economics from Warwick University in the UK.Yunus Carrim: Carrim holds a master’s degree in sociology from Warwick University and a diploma in journalism from the Darlington College of Technology, also in the UK. He was a senior lecturer in sociology at the University of KwaZulu-Natal. He replaces the controversial Dinah Pule, who was sworn in as minister of communications on 25 October 2011.He chaired several portfolio committees, including justice and constitutional development (2007 – 2009), public enterprises (2004 – 2007) and provincial and local government (1998 – 2004).Carrim, the former deputy minister of cooperative governance and traditional affairs, is described as a leading advocate of initiatives to eliminate corruption in the government.In a radio interview the day after being sworn in, Carrim said that he was committed to working with his deputy minister in making the department more unified and “far more developmental in service delivery and orientation”.He also acknowledged the need to stabilise the volatile board of the South African Broadcasting Corporation, and improve its performance.He said that he doesn’t feel at a disadvantage for not having an ICT qualification, adding that the role of the minister is to bring together the technical people who do have the necessary skills, and to provide strategic and political guidance.He spoke of a revival of the communications department, but with elections coming up in 2014, the department’s new focus and energy would only come into play after voters go to the polls.Carrim is replaced by Andries Nel, the former deputy minister of justice and constitutional development, who is himself replaced by John Jeffery.Nel has a degree in civil law from the University of Pretoria. He has also been active in Parliament, holding the position of house chairperson in the National Assembly from 2008 to 2009, and acting chief whip of the ANC in 2006 and 2007, while serving as deputy chief whip between 2002 and 2008.Nel was the co-ordinator for the Lawyers for Human Rights’ capital punishment and penal reform project from 1990 to 1994.New deputy ministersBesides Nel and Tshwete, the other two new deputy ministers are John Jeffery – justice and constitutional development – and Michael Masutha – science and technology. The latter position has been vacant since October 2012.Masutha, an advocate, is the former head of the Disability Rights Unit of Disabled People South Africa, and played an important role in developing the organisation’s constitution and charter. He holds law degrees from Wits University and the University of the North.In Parliament he served on several portfolio committees, including justice and constitutional development, social development, and constitutional review. He was also the chairperson of the standing committee on the auditor-general.Analysts have commented on Masutha’s lack of suitable qualifications for the science portfolio, but say his experience on portfolio committees and his legal background could contribute positively to issues of compliance, and boost the economic and financial management of the department.John Jeffery is a member of the justice and constitutional development portfolio committee in the National Assembly.He holds a bachelor’s degree from the University of Natal (now the University of KwaZulu-Natal), as well as an LLB and a postgraduate diploma in environmental law from the same institution.
The heat is conducted from the shingles to the sheathingThe part we’re concerned with here is the sunlight that’s absorbed by your roof. Once the roof sucks up those rays, it gets hot. That heat at the absorbing surface (shingles on most residential roofs) then does what the Second Law of Thermodynamics tells it to do — it looks for cooler places, so it starts conducting down through the roofing materials. When it finds the underside of the roof deck, it then can radiate down into the attic. Typical roof decking materials — plywood and oriented-strand board (OSB) – are pretty good radiators, so everything they “see” in the attic starts getting hot, too.You can see the heat transfer I just described in the diagram labeled Figure 1 below. Here’s the basic process:Radiation hits the roof.The radiant energy is absorbed by the roofing materials.The thermal energy conducts downward.Heat radiates from the roof deck to everthing in the attic. The heat radiates into the attic from the underside of the sheathingSo, the dominant form of heat gain in an attic is from radiation, which heats up all the solid materials it finds — framing, ductwork, insulation, all those boxes of Christmas decorations, and dead squirrels. That’s one reason powered attic ventilators aren’t a good solution. They’re going after the air, but the air is hot only because all the solid materials are hot.A better way to reduce the attic temperature is to go after the source — the radiation constantly blasting the attic from the bottom of the roof deck and rafters. Plywood and OSB are good radiators. In physics language, they have high emissivity, which means they’re good at emitting radiant energy.That’s where radiant barriers come in. These are materials that have a low emissivity. When the underside of the roof deck has a radiant barrier installed, the heat still travels through the materials, but once it hits the radiant barrier, it’s come to a dead end. Little of that heat then radiates to the attic.The radiant barrier gets hot. If you go up into the attic and touch it, you’ll see that the heat’s still getting there. But like that stainless-steel playground slide shown at the top of this article, when you hold your hand near it without touching, it doesn’t feel like it’s hot. The magic of low emissivity! Today just feels like a good day to talk about shiny stuff. Radiant barriers are a green building product with a lot of sex appeal, if that’s possible for construction products. People get really crazy about attics, though. (Don’t get me started about powered attic ventilators!) Maybe brains have a tendency to overheat when discussing them. The general category of radiant barriers is an area of great hype and misunderstanding, so I’ll tell you what I know, explain the basic physics, and give you a couple of links to some great resources for more information.OK, first of all, a radiant barrier is something that can keep your attic cooler. Unlike powered attic ventilators, they actually go after the source of the problem rather than treating a symptom — but first, let’s look at the physics.Attics get hot because the sun is beating down on them all day. The heat from the sun comes in the form of electromagnetic radiation. When this radiation hits a surface, it can do one of three things: It can be (i) reflected, (ii) transmitted, or (iii) absorbed. How much of each you get depends on the wavelength of the radiation and the properties of the material it hits. Radiant barriers need an air gapIn case you’re wondering, the answer is yes, this is the same thing that makes low-e windows so good. Also, if you’re wondering how hot the shingles get, the Florida Solar Energy Center has done research on that, which I wrote about a while back.OK, so if the radiant barrier doesn’t feel hot when you hold your hand an inch away but it can burn you when you touch it, what does that mean for installation? You got it! You have to have an air gap next to the radiant barrier. If you spray foam insulation right on the radiant barrier, you’ve wasted your money on the radiant barrier. Heat will conduct right through the radiant barrier because generally, materials with low emissivity have high conductivity. More resourcesThere’s so much more to say about radiant barriers, but let me wrap up this article and give you a couple of resources where you can read more about how they work, how to install them, how much they might save, and why you probably don’t want to install one in Pennsylvania or other cold-climate locations. The first is the Florida Solar Energy Center (FSEC). They have a bit of radiant heat gain in attics down there and know a thing or two about this topic. Here’s a good Question and Answer Primer that’s got a lot of good info.Oak Ridge National Laboratory, which does a lot of great building science research, has several good pages about radiant barriers, too.Another great study is the Houston Home Energy Efficiency Study (pdf). This was a study done by Michael Blasnik and Advanced Energy, and among other things, they looked at the cost-effectiveness of radiant barriers. What they found was that in Houston, Texas, radiant barriers reduced the cooling consumption by about 3%. The paper is well worth the read, in case you don’t already have a copy. (Oh, yeah…it’s free!)Finally, here are a couple of good resources that address the question of if or when you should install a radiant barrier. Martin Holladay wrote Radiant Barriers: A Solution in Search of a Problem a couple of years ago here at Green Building Advisor and included a lot of great info on the topic. Also, a new website called Radiant Barrier Truth tackles the issue of radiant barriers in cold climates.I’ll come back to this topic and write more another time, but for now, let’s not forget what my friend Mike Barcik says is one of the most appealing features of radiant barriers: People like shiny stuff!
India relied on spinners Baba Aparajith and Harmeet Singh to pull off a thrilling 9-run victory over New Zealand and cruise into the final of the ICC U-19 Cricket World Cup here on Thursday. SCORE | PHOTOSDefending a modest total of 209, Indian bowlers maintained their consistency throughout as they restricted New Zealand to 200 for nine in their 50 overs to set up a title clash against Australia on Sunday.Needing 18 off last over, medium pacer Sandeep Sharma kept his cool as he gave away only nine runs as India made it to summit clash quite comfortably in the end at the Tony Ireland stadium.Young Tamil Nadu lad Aparajith got his second successive man-of-the-match award for his all-round show as he scored 44 before taking the important wicket of Robert O’Donell.This is India U-19 team’s fourth appearance in the final of the tournament having won the 2000 and 2008 editions while they were runners-up in 2006.A target of 210 was never a tall-order for the Black Caps colts but all-rounder Aparajith (1/29) and the young sardar from Mumbai Harmeet (2/30) stifled the set New Zealand pair of Cam Fletcher (53) and O’Donell (29) in the middle overs to set it up for the Indians.The duo gave away only 59 runs in the 20 overs between them and also shared three wickets. The highlight certainly were the Batting Powerplay overs where two of them gave away only 14 runs in the five overs.While New Zealand lost the first four wickets for 63 runs, Carter-O’Donell duo put on 56 runs for the fifth wicket without much fuss. It looked as if New Zealand were cruising along towards victory before Harmeet-Aparajith applied brakes on scoring. Back to-back maidens in the 34th and 35th overs suddenly increased the pressure on the Kiwis.advertisementAs the pressure mounted, O’Donell closed the face of his bat to an off-break from Aparajith to offer a simple return catch as India made decisive inroads.
