Both are not-for-profit organisations based in Johannesburg.The Life College Group is the brainchild of social entrepreneur and television news anchor Pat Pillai, who is also an Ashoka Globaliser Fellow. Ashoka is a global organisation that identifies and invests in leading social entrepreneurs that have innovative and practical ideas for solving social problems.The programme draws on the vision and values of prominent South African leaders such as former president Nelson Mandela.According to Verne Harris of the Nelson Mandela Centre of Memory, the programme is based on the book, Conversations with Myself by Nelson Mandela, as well as his extensive personal archive.Changing the way young people thinkIn a statement Achmat Dangor, CEO of the Nelson Mandela Centre of Memory, said that the goal of the programme is to harness the life-work of Nelson Mandela and his generation of leaders to build a nation of champions.“Our goal is to reach one-million youth by 2020 and inspire them to make every day a Mandela Day,” Dangor said. “We will do so by partnering with and offering the programme to schools, universities, companies, civil society and government youth programmes.”Pillai, Life College Group CEO and lead facilitator of the programme says that a great opportunity exists to positively influence young South Africans.“The mindset of the nation and the youth is up for grabs,” he says. “Do nothing and we risk too much.”Although the programme draws on the values of prominent South Africans such as Nelson Mandela, the programme encourages students to be authentic.“It’s not about losing one’s own individuality, but rather a process of deconstructing the Mandela legend to get to the core principles by which he leads his life,” Pillai explains. “We want to help students be the best that they can be.”Launching the programme in Port ElizabethThe programme was formally launched at the Missionvale campus of the NMMU.During the university’s orientation week, about 5 000 new first-year students participated in a day-long dialogue workshop aimed at enabling them to think and act like the university’s namesake.The workshop was facilitated by Life College and NMMU facilitators in an innovative and fun way.“Our belief is that we will only succeed in making our country and world a better place if each one of us lives the changes we want to see in the world,” NMMU vice-chancellor Prof Derrick Swartz said in a statement.According to Swartz, the NMMU will repeat the programme every year until 2020 to achieve its goal of reaching 50 000 students.“By scrutinising the Mandela legacy, students are asked to start thinking critically, to understand the power of their own purpose and to think critically about circumstances and choices, among other things,” Pillai says.Guest speaker at the launch, NMMU chancellor Santie Botha said that Nelson Mandela is an outstanding role model for students.“With this workshop we tell students how to learn from his greatness and to make it their own,” Botha said.Round table facilitator Ruby-Ann Levendal, who is also the director for transformation, monitoring and evaluation at the NMMU, hopes the workshop discussions will help students to see themselves in a new light.“It is really just about triggering a different, lateral way of thinking which our secondary education does not always give our youth,” Levendal says.Become a committed championOn completion of the programme, students are asked to sign a pledge to implement their personal action plans to achieve their champion status. Students also appoint their own integrity partners who will offer support and help them to achieve their goals.Eighteen-year-old Chamonay Johnson who enrolled at NMMU for a LLB degree says she was surprised by how little she know about Nelson Mandela and his life.For Johnson, the take home message of the workshop is that Mandela never gave up, and she hopes to apply this principle in her own life as a student.“It does not matter what it takes, I will get my degree,” she says.More inspirational South AfricansApart from Madiba, the lives and achievements of other noteworthy life champions such as former Constitutional Court Justice Albie Sachs and Pick n Pay founder Raymond Ackerman, will also serve as inspiration to students.The University of Cape Town, the National Research Foundation, Citadel, the Development Bank of South Africa and other project partners have also signed up for the programme.

RELATED ARTICLES Providing Fresh Air in Our HomeCommissioning Our Heat-Recovery VentilatorDesigning a Good Ventilation System GBA Encyclopedia: Ventilation ChoicesAre HRVs Cost-Effective?Using a Glycol Ground Loop to Condition Ventilation AirHRV or ERV?A New Way to Duct HRVsVentilation Rates and Human HealthHow Much Fresh Air Does Your Home Need? Joseph Lstiburek: Just Right and Airtight Three operation settingsOur HRV has three speeds, plus an extra-low “away” setting. Labeled 1, 2, and 3, the primary settings can be custom-set to deliver between 29 and 218 cubic feet per minute (cfm). As configured on our system, Setting 1 consumes 18-20 watts, Setting 2 consumes 30-35 watts, and Setting 3 consumes 80-85 watts. The Away setting uses just 7-10 watts.There is a frost-protection cycle that goes on periodically in cold weather to prevent condensate from freezing in the heat exchanger core. This draws about 800 watts. The need for this can be greatly reduced by adding a ground-loop preheater. This circulates an antifreeze solution through a simple ground loop (tubing that can be buried along the house foundation during construction). Plastic ductsNearly as exciting as the superb energy performance of Zehnder HRVs is the ducting that is provided with them. The company produces ComfoTube ducting with a 3-inch outside diameter and 2.5-inch inside diameter. The outer surface is ribbed for strength and the inside is smooth for optimal airflow and quiet operation. The material is 100% high-density polyethylene, which is the most environmentally friendly plastic, in my opinion.The ducting diameter is small enough to fit in 2×4 interior walls. Because the airflow rate through the ducts is relatively low and sharp bends are eliminated, the airflow delivery is very quiet. In fact, noise control is a key feature of all Zehnder products, and this is one reason the HRV itself is so quite large.While some ducting systems for heating and ventilation are branched — with larger trunk ducts stepping down to smaller distribution ducts — Zehnder ComfoTube ducts are designed to be installed in a “home run” configuration, with a single, continuous duct extending from each supply and return diffuser all the way to the HRV. This feature also helps control noise, though it can make for a complicated spaghetti-like installation. Our Zehnder HRV delivers between 2.6 and 3.3 cfm per wattThe HRV we installed in our new house is a Zehnder ComfoAir 350 Luxe. This is a Swiss-made, highly efficient HRV utilizing a counter-flow heat exchanger. In fact, testing by the Home Ventilating Institute (HVI) shows it to be the most energy-efficient HRV available. The American division, Zehnder America, is off to a rapid start, with about 800 installations in North America since its launch several years ago, according to business development director Barry Stephens.There are various ways to measure the efficiency of HRVs. Apparent sensible effectiveness (ASEF) is the most commonly reported number for heat transfer efficiency. The HVI-listed ASEF of our Zehnder unit is 93% — which is among the highest in the directory (though not quite the highest).Another measure reported by HVI is the sensible recovery efficiency (SRE). This is a measure that corrects for waste heat from the fan motor that may be going into the incoming airstream, cross-flow leakage from the outgoing to the incoming airstream, and case leakage or heat transfer from the outside of the box to the airstream inside. These factors make it seem as if the heat transfer efficiency is higher than it really is; thus the SRE number is more accurate. With our Zehnder ComfoAir 350 the SRE is 88% — the highest that I found in the HVI Directory.In reviewing the HVI list of certified products, I found some other HRVs with higher ASEF values, such as a Broan-NuTone model with a listed ASEF of 95%, but that product had a SRE value of only 58%. With that product and most other HVI-listed models that have very high ASEF values, the SRE values are considerably lower, indicating that waste heat from high-wattage fan motors or other losses are boosting the ASEF values.Another measure of efficiency is how much air is moved per unit of electricity consumed. Here we can look at the cubic feet per minute (cfm) of air flow per watt of electricity consumption. With this metric, the Zehnder ComfoAir really shines, achieving a remarkable 2.58 to 3.25 cfm per watt (depending on the fan speed). The Energy Star criteria for HRVs to be listed as EnergyStar is 1.0 cfm/W, and most good HRVs have air-delivery efficiencies only in the 1.0 to 1.5 cfm/W range. I was able to find only a few others with cfm/W values exceeding 2.0.(Several Panasonic exhaust fans have higher cfm/W numbers; for example, the Panasonic FV-05VK3 is rated at 12.4 cfm/W. However, these fans do not provide any heat recovery.) In last week’s blog I reviewed some of the general strategies used for ventilating buildings — or not. This week, I’ll zero in on the types of balanced ventilation in which heat is recovered from the outgoing airstream to preheat the incoming fresh air. By the way, Eli Gould (the designer-builder of our home) and I will be leading a half-day workshop at the NESEA Building Energy Conference in Boston on Tuesday, March 4, 2014. In this workshop, “What Would the Founder of Environmental Building News Do? Adventures on the Cutting Edge of Green Building,” we’ll be reviewing product and technology choices, describing lessons learned, presenting data on performance, and discussing, in a highly interactive format, some outcomes from this project that can be applied much more affordably in deep-energy retrofits. This should be informative and a lot of fun. Registration information can be found here. A pricey applianceIn my opinion, Zehnder makes the best HRVs and ERVs (energy-recovery ventilators) in the world. But you pay for that quality and performance. The system we have, a Zehnder ComfoAir 350 Luxe with ten supply ducts and ten return ducts, with their respective registers and two remote controllers (for the upstairs and downstairs bathrooms), costs about $6,000. The geo-exchange loop, which we did not include, adds another $2,000.While this is a lot to spend on ventilation, this integrated whole-house ventilation system obviates the need for separate bath fans, which can cost $300 to $600, installed, and some of that extra cost will be recovered over time through energy savings during operation compared to standard HRVs.The super-quiet, highly dependable operation is a nice bonus.In next week’s blog I’ll talk about commissioning our HRV system. Two fans, two airstreamsAs noted last week, balanced ventilation requires two fans: one bringing fresh air into the house and one exhausting indoor air. By balancing these two fans and the airflow through their respective ducts, the house is maintained at a neutral pressure — which is important for avoiding moisture problems or pulling in radon and other soil gases.In a heat recovery ventilator (HRV), the two fans are in the same box, and they force air through a heat-exchanger core made of a corrugated plastic or aluminum. There are several types of heat exchanger cores in HRVs, and these affect efficiency and cost.HRVs can have cross-flow heat exchangers or counter-flow heat exchangers. With cross-flow, the incoming and outgoing air streams are typically at 90° angles to each other. The heat transfer efficiency is good but not great: typically 50% to 70%.With a counter-flow heat-exchange core, there is a longer pathway across which heat exchange occurs, so the efficiency is typically higher.
