Breakthrough technology makes Soweto school among world’s greenest

first_imgLYT Architects vision of a new type of school envisions the outside being as much part of the classroom as the building. (Image: LYT Architects)• S. MakhaniPrincipalSt. Martin de Porres+27 11 936 [email protected] PhilipCurious kids come and go, watching from the top of an embankment as the first of the four structures of their new campus rises on what was once the school’s sports field. The field is now a dust bowl, the grass churned over by trucks and boots. The backhoe pulling down the embankment sends clouds of dirt and grass into the air each time it slams into the dry earth.St Martin de Porres High in Orlando West, Soweto, is not an average township school. Once its new campus is complete it will be one of the most environment-friendly and sustainable schools in the world. Twenty new classrooms will replace temporary structures of brick and zinc built 50 years ago. The campus is being constructed using modular building technology developed in South Africa and using a Green School design concept developed by South African architecture firm LYT Architects.Constructed from prefabricated panels manufactured offsite, the four structures use integrated solar technology and natural light to reduce power consumption from the grid. Instead of traditional peaked roofs, the buildings’ flat roofs will be able to harvest rainwater for watering the gardens and sanitation.Sliding panels allow natural airflow to warm and cool the rooms, and wash each classroom with sunlight. Sustainability will even extend to schoolwork. The 720 pupils will be given tablets for their studies to make the school as paperless as possible, and horticulture and recycling will be included as new subject choices.A different kind of teachingPatrick Nayler, a director at LYT Architects, says the firm’s belief that buildings influence life is central to their concept. “The sliding doors and open walkways are integral to the design. It allows a different kind of teaching to take place, one that elevates the indoors as much as the outdoors. We should be encouraging education outside the classroom as well; we have the climate that makes it possible.“We envision the school becoming a communal node, expanding beyond its function as a school. Organic hydroponic gardens will be established to educate the learners and community members about intensive, highly productive methods of farming, and to produce healthy food for the school learners, as well as a modest income for the local community.”Offsetting carbon emissionsDesigning intelligent buildings is one thing; even better is having the technology to make them a reality. The South African developed, world-leading green technology allowing the first structure to be erected in days, and the entire school in a month, is the result of a partnership between Sasol and Novo Domus, a construction systems design company.Two of the three largest industrial polluters on Earth are South African. Power utility Eskom and petrochemicals giant Sasol are both dependent on coal, and their resultant emissions put the country at risk of being fined billions for not meeting its commitments to the Kyoto Protocol.The technology used by Novo Domus – the name means “new house” in Latin – comes out of billions of rands of research funded by Sasol to offset their carbon emissions. The prefab walls and insulation foam use the byproducts of its coal to liquid fuel process.“What does Sasol gain by shutting down production?” asks Keith Warmback, the project manager and owner of Novo Domus “Nothing, plus the number of jobs lost directly and indirectly would be staggering. Funding this research, incubating companies to take advantage of the research, creates jobs as well as helps Sasol to generate carbon credits to offset its carbon footprint.”In the relative quiet of the site office, Warmback sits in front of a desk covered in architectural plans. “It’s not just the buildings. The entire process is green. The trucks bringing panels from factory to site as well as all the construction equipment run on biofuel. There is no waste because the entire building is made to order.”Easing the healthcare and housing backlogWarmback believes the technology is a cost-effective solution to the backlog of school construction in the country. Steel panels are slotted into place for walls with PVC resin used as insulation. Double-glazed window frames and ceiling panels keep the temperature a constant 18 degrees Celsius no matter the weather outside.The construction site is not as loud or chaotic as a traditional site. For one thing, the crew is smaller – there are no bricklayers. Other than skilled artisans and heavy machinery operators, the crew consists of local community members trained by Novo Domus in the new construction technique. Warmback says the simplicity of the modular structures makes their construction an easy skill to learn. “We built a school in the rural Eastern Cape. There is nothing there, no roads, a mud school and houses built out of mud and thatch. We built a school with people we trained in the local community. Those skills are now being used to build houses and clinics.”The construction of an entire school is a lot faster and a lot cheaper than a traditional bricks and mortar structure – R30 000 instead of R1.5-million. There is a lot less waste than in traditional wet work construction, which requires bricklaying, plastering and pouring concrete. “As much as 25 % of material is wasted in traditional construction,” Warmback says. “The modular design with prefabricated panels means there is no waste. Another advantage is that any material available in abundance in any location can be substituted in the process.”Novo Domus will be redoing the roads and parking lots at St Martin de Porres as well. Instead of traditional tar they will be using a new polymer adapted from an Israeli technology. Guaranteed not to crack or develop potholes for 10 years, it has been tested at a mine in Australia for the past four years. “The surface flexes and grows harder and stronger the more traffic using it. It’s new technology and, once it proves successful here, we hope to use it across the country.”Combating anxiety over new technologyNovo Domus has found it slow going convincing government departments and contractors to accept its modular building technique, despite it being the standard internationally. Since it built its first structure, a simple single room displayed at COP 17 in Durban, most of its orders have come from international clients. In Liberia they have built 5 000 low-cost houses; in South Africa just a dozen schools.Nayler, of LYT Architects, identifies the problem simply. Everyone wants a brick structure because that is what they know, he says. “What mitigates against adoption of this concept and technology is the concerns of the holders of the purse strings. The more buildings we put up the faster the anxiety over a new technology dissipates.”The first building at St Martin de Porres has been completed in time for the international C40 Mayors Summit, which begins in Johannesburg today. Joburg mayor Parks Tau will host a delegation of mayors from the 63 cities attending the summit at the school. For the mayor, a parishioner of the congregation of St Martin de Porres, it is a showpiece of the city’s programmes to combat climate change.“We have a responsibility to provide leadership and to share our experiences, best practice and capacity for innovation with the rest of the globe,” Tau said ahead of the opening of the summit. “Climate change is one of the greatest challenges of our time, in the end, we are measured not by how much we undertake, but by what we finally accomplish.”last_img read more

Insulating an Exposed Floor

first_imgOur expert’s opinionWe asked GBA technical director Peter Yost for his opinion. Here’s what he had to say:Without a vapor retarder between the conditioned space and the first condensing surface, and with the first condensing surface only warmed by 3/4 in. of rigid foam, it sure sounds as though the air-permeable cavity insulation is cooling the cavity enough for condensation to occur. But if this were simply diffusion of interior moisture into the floor cavity, we should see condensation throughout, rather than just in some areas of the floor. So, that makes one think that the problem is due to air leakage.I would confirm the air leakage, either with a blower-door test, or, if one is not readily available, by investigating with a smoke stick after you have turned on every exhaust fan in the house. I have induced an interior/exterior pressure difference of 30 pascals (60% of a typical blower door test) by just turning on every exhaust fan (baths, kitchen hood, and clothes dryer) and a pretty powerful window box fan.What makes me nervous is to go with just the information you currently have, thinking we know where the moisture is coming from, but not making sure. Before you close up the floor system, it would be a good idea to take full advantage of having the floor system open for inspection.Why not tape the seams of the subfloor before you put down the finish floor, to add an interior air barrier? Two air barriers are always better than one, and it sounds as though it is quite possible to make the interior air barrier continuous.Concerning the temperature of the finish floor during the winter: I built a kitchen addition on piers in southern Vermont using R-38 SIPs for the floor, walls, and roof. During the first really extended cold snap, my wife walked across the kitchen floor, moving from the old floor (over the heated basement) to the new floor. “Why is this floor so cold if you used such a high performance building system?” she asked. I explained that the temperature of the floor of the addition was exactly the same temperature as the addition’s walls and roof. She looked at me and wryly said, “Well, now I feel so much better.”I sure wish I had thought of Joe Lstiburek’s approach — decoupling that finished floor with an airtight air space beneath it. I can add more rigid insulation under the R-38 SIPs floor panels, but since insulation just slows conductive heat loss rather than stopping it, I can’t add enough to beat the longest cold periods. That addition’s floor will still be noticeably colder than the floor over the old basement many times throughout the winter.So, in this case, adding more rigid foam underneath the floor framing system (warming the first condensing surface) and providing an airtight space above the cavity insulation will result in better energy performance, moisture management, and thermal comfort. Vapor Retarders and Vapor BarriersForget Vapor Diffusion — Stop the Air Leaks!Installing Fiberglass RightGreen Basics: Insulating Roofs, Walls and Floors Fine Homebuilding: How to Insulate a Cold Floor Calculating the Minimum Thickness of Rigid Foam Sheathing The flooring manufacturer has recommended a layer of #15 asphalt felt between the strip flooring and the subfloor, but Mr. Mike is concerned this may trap moisture in the floor system, making the situation worse than it already is.Should he remove the foam and re-install the OSB? Add more foam to the bottom of the floor system? Insulate the tops of the 2×10 beams with foam?Those questions are the start of this installment of Q&A Spotlight. Make the foam thicker and seal the air leaksTo David Meiland, this problem seems to be caused either by the insufficient R-value of the rigid foam insulation on the underside of the joists, or by air leaks. If there are air leaks between the house and the addition, they could be the source of the moisture that seems to be condensing inside the joist cavities. The problem could be made worse by a forced-air heating system that’s slightly pressurizing the house interior.As to the foam, Meiland says, “it should either be omitted or made much thicker.”And this makes sense to GBA senior editor Martin Holladay. “This is either an air sealing issue, or perhaps the home is being pressurized,” Holladay says. “In any case, it’s possible that the condensation is a seasonal phenomenon, and that the moisture will dry harmlessly as the weather changes. (The floor system will have some air exchange due to fluctuations in outdoor temperature.)”Holladay suggests that Mr. Mike read an article he wrote for Fine Homebuilding magazine about insulating floors over cold spaces.Mr. Mike replies that he doesn’t have a forced-air heating system. “I think I have air leakage on the sill/rim joist from where the addition is attached to the house where the warm air from the basement [can] enter the floor system,” he adds. “The moisture does seem to be more in that area, and I was considering installing rigid foam against it on the addition side.”He has sealed some of the OSB seams with caulk, but he suspects cold air may be leaking into floor system in the area of the 2×10 beams.Holladay notes, “When you have wintertime condensation in a cold area of your thermal envelope, the source of the moisture is usually interior air, not exterior air. (Exterior air is dry; interior air is moist.) It is unlikely but possible that there is a path for warm, moist, interior air to reach the cold rigid foam. However, the stack effect usually prevents this kind of air leakage. It is even possible that there was no condensation until you opened up the floor. Once you opened up the floor, interior air had access to the cold foam (for the first time).” A GBA reader who calls himself “Mr. Mike” is working on an 11-ft. by 14-ft. addition to his house in central New York that sits some 5 feet off the ground. The space beneath the addition is a great place to park a lawnmower, but it’s also open to the cold.The floor joists are supported by two beams, each a tripled 2×10. To insulate the floor, Mr. Mike put two layers of R-13 unfaced fiberglass batts in the joist cavities, ran a 3/4-in. layer of Cellofoam foil-faced rigid insulation over the bottoms of the joists, then covered the insulation with 1/2-in. oriented strand board (OSB) to keep out pests. The subflooring is 3/4-in. tongue-and-groove plywood.All seemed to be well until Mr. Mike got ready to install strip flooring in the addition.“When I pulled the existing carpet up to redo the floor, I made a couple of access holes to inspect the cavity and found signs of frost and condensation on the foam insulation — but only in certain areas, closer to where the addition is attached to the house,” Mr. Mike writes in a post at Green Building Advisor’s Q&A forum. RELATED ARTICLES Use felt under the floorMr. Mike’s fears that the asphalt felt will trap moisture in the floor system are probably unfounded, Holladay says, and on this issue Mr. Mike is probably “overthinking” the problem.“Go ahead and put rosin paper or asphalt felt under your new oak flooring,” Holladay tells him. “(Some people prefer rosin paper to asphalt felt because they are worried about asphalt odors. However, as long as you don’t have hydronic tubing in your floor system, I would use either one without worrying.)”“The felt under the flooring is a non-issue,” Meiland adds. “Assuming no radiant tubing in the floor, or other source of heat that will bake it, install the felt. I put felt under my wood floors and have done it on many jobs for others over the years.” What if we’re starting from scratch?Part of the problem is the two 2×10 beams that support the joists. Because of the way the addition is framed, the beams interrupt the layer of rigid foam insulation.“A flush beam, on the other hand, supports the joists with joist hangers,” Holladay says. “If you had installed a flush beam, it would have been easier to install a continuous layer of rigid foam on the underside of the floor system.”The discussion prompts Dennis Dipswitch to recommend an article on the topic by building scientist Joseph Lstiburek.In that article, Lstiburek writes that it’s possible to build a warm floor over a cold space by using a layer of rigid insulation below but also by leaving an air space between the cavity insulation and the subfloor. In other words, don’t completely fill the joist cavity with insulation.Although it may seem counterintuitive, floors are warmer this way because the warm air keeps the tops of the joists warmer and reduces thermal bridging somewhat, Holladay says. The airspace will keep the floor warmer“Lstiburek’s approach — leaving an air space between the top of the insulation and the subfloor — is dangerous to follow if you are a builder with average skills, because air leaks in floor assemblies routinely allow cold exterior air to infiltrate the joist bays,” Holladay adds. “Once that happens, this detail is a disaster. The detail only works if the builder has impeccable air sealing skills. That’s rare, but possible.“Here’s the bottom line: The insulation that is doing most of the work in this assembly is the continuous layer of rigid foam under the joists. If you want a warmer floor, beef up the thickness of the rigid foam — and do an impeccable job of air sealing at the perimeter of the floor assembly (the rim joist area). Then it hardly matters how much fluffy stuff you put between the floor joists. You can put in a little (the Lstiburek approach) or a lot (my way).”last_img read more

Facebook Has 1 Billion Users & I Have Three Questions

first_imgThe Dos and Don’ts of Brand Awareness Videos Guide to Performing Bulk Email Verification Related Posts A Comprehensive Guide to a Content Audit So Facebook has reached the impressive milestone of 1 billion active monthly users. What does it mean? Hard to know without a bit more information.In today’s exclusive interview with Matt Lauer on NBC’s Today Show, Zuckerberg said, “I really only want to go out and talk when there’s something to say.” But that’s not entirely true. Zuckerberg only likes to go out when there is something good to say, and, even then, only when the interview is highly scripted.And that’s why Lauer pressed Zuckerberg harder about his May wedding than the company’s dismal stock performance. Lauer seemed more interested in comparing who has more drawers for their clothes (Zuckerberg one, Lauer considerably more) than digging in deep on how the company plans to catch up in mobile. The interviewer let it go after the CEO pointed out that there are five billion mobile phone users in the world that Facebook could capture as customers.)The tech and business press weren’t much more circumspect. In the most-widely circulated story so far, TheNextWeb’s Emil Protalinski gushed over Facebook’s “big news” and even Bloomberg assumed “the next billion” was a given.Unasked & Unanswered QuestionsI wish Lauer had asked Zuckerberg the following questions. (I’ve been trying to do it myself. I’ll update this post as soon as I hear back.)Facebook officially recorded its billionth signup on Sept. 14. Why the delay after months of predictions that it would reach one billion users in August, if not sooner? (Some reports have alluded to the fact that Facebook has had trouble with phony accounts and was most likely waiting until it was sure it had one billion “real” users. Could be.)What exactly is an active monthly user? It has been widely reported how difficult it is to delete a Facebook account, but I’ve heard anecdotal reports of people deactivating their accounts, either permanently or for long stretches of self-imposed Facebook exile. Is there an uptick in deactivated accounts and, if so, were those counted in the 1 billion figure?How are we to understand the lag time between 900 million and one billion when compared to 800 million and 900 million? To me, it suggests that Facebook has saturated the market.But even those question obscure the bigger issue: 1 billion users is impressive, but it’s an arbitrary milestone. If Zuckerberg is serious about only talking when there’s something to say, now is the time to say something. It’s time to let shareholders know exactly how (whether?) the company hopes to reach 2 billion users and to tell users how their experience will change as Facebook’s status as a public company forces it to focus more on revenue and less on its original mission of connecting the world.center_img dave copeland Facebook is Becoming Less Personal and More Pro… Tags:#Facebook#web last_img read more

BCCI plans to rest seniors for NZ ODIs

first_imgIn a clear indication of where its priorities lie, the Board of Control for Cricket in India (BCCI) is reportedly planning to leave out some of its top players from the One-Day International series against New Zealand next month and send them to South Africa to prepare for the Test series that follows.India have never won a Test series in South Africa and the BCCI is apparently keen to send the senior cricketers well before the start of the series – on December 16 – to get acclimatised to the conditions.Dhoni and Tendulkar”We are planning to send the key Test players to South Africa early to prepare for the series. The conditions in South Africa are quite different and we want to give our players enough time to come to terms with the conditions,” a BCCI source told PTI. New Zealand are scheduled to play three Tests and five ODIs in India from November 4 to December 10.But with the BCCI drawing up this plan, many of the top players may skip the ODIs. Batting icon Sachin Tendulkar, captain Mahendra Singh Dhoni, Rahul Dravid, VVS Laxman, Virender Sehwag, Gautam Gambhir, Zaheer Khan and Harbhajan Singh are likely to be in the batch which will leave for South Africa early.BCCI’s foresight, it seems, is reserved to only the South Africa tour and not for the Asian Games, which starts from November 12. Twenty20 cricket will be part of this year’s Asiad. In June this year, the BCCI had announced that it will not send teams from India in men’s or women’s categories to Guangzhou, China, due to ‘international commitments’.advertisement”We would not be able to send our team, both men and women, for the Asian Games in China because of international commitments,” the BCCI chief administrative officer Ratnakar Shetty had said.With the latest move, it seems the BCCI is ready to dilute the entire ODI series against New Zealand to increase the team’s chances in South Africa, but is unwilling to string together a Twenty20 team for a prestigious event like the Asian Games, which is being staged from November 12 to 27.And ironically, it was after India put its weight behind the inclusion of cricket in the Asian Games that T20 was included. When the BCCI announced that the Indian team won’t be sent to the Asian Games, the contentious ‘whereabouts’ clause of the World Anti Doping Agency (WADA), which is in operation at all major international events, was seen as a reason for the board’s reluctance to field a side. The board had said that the anti-doping clause was an infringement on players’ privacy.Aussies depletedIn another setback for the already struggling Australian team, batsman Michael Hussey and fast bowler Doug Bollinger have been ruled out of the third and final ODI against India in Goa. Bollinger reported some minor abdomen discomfort in an area unrelated to the original injury that ruled him out of the second Test and second ODI of the tour.Hussey will return to Australia following the second one-day international game, allowing him to play in West Australia’s Weet-Bix Sheffield Shield clash with South Australia.–With inputs from agencies.last_img read more
