Building Science Pioneer Dies

first_imgInventor of the chainsaw retrofitGBA senior editor Martin Holladay met Rob Dumont when they were both invited to an expert panel on residential retrofit work in Winnipeg, Manitoba in June 2006 (see Image #3, below). “I interviewed Rob several times over the years,” Holladay recalled. “He was a humble man, quiet and unassuming, and he had a deep understanding of residential energy issues. He was unfailingly kind and generous with his time.”Holladay notes that Rob Dumont, along with his colleague Harold Orr, was the originator of the chainsaw retrofit method. Dumont and Orr were co-authors of a classic 1987 paper, A Major Energy Conservation Retrofit of a Bungalow, a thorough documentation of the world’s first chainsaw retrofit. Varied contributions to buildingDumont moved to Saskatoon in 1970 and earned a master’s and doctoral degrees from the University of Saskatoon before starting his career with the National and Saskatchewan Research Councils.Anil Parekh, a professional engineer with Natural Resources Canada, first met Dumont in the late 1980s and worked with him on a number of technical committees over the years. Asked about Dumont’s most important contributions to building science, Parekh rattled off a long list of accomplishments, including his early work on heat recovery ventilators; authorship of computer code that later became HOTCAN for heat loss and heat gain calculations; development of the so-called Factor 9 home that became the cornerstone of net-zero energy building in Canada; and pioneering research that “paved the way for developing [the] ‘house as a system’ approach to deep energy retrofits in Canadian homes.”“He knew the whole house as a system,” Parekh said by telephone, “that when you change on component it’s going to change the others. One really has to look at the practical effects of it. At the same time, he also knew that energy efficiency had to live with indoor air quality.”Parekh recalled that Dumont was part of a team that worked in a garage on the university grounds to develop the first heat-recovery ventilator (HRV) for houses, and idea that was later widely commercialized. HRVs, which provide mechanical ventilation with a minimal energy loss, are now standard for tight, high-performance homes.According to the obituary published in Saskatoon’s The Star Phoenix, these and other projects helped Dumont win a number of awards, including Canada’s National Energy Efficiency Award in 1999 and the leadership award from Building Saskatchewan Green in 2014. The houses that made a differenceFew projects on Dumont’s resume have made as big an impact as the Saskatchewan Conservation House. Although it was boxy and ungainly, it nonetheless incorporated all of the principles that became hallmarks of Passivhaus construction.Dumont was one of 11 team members, led by Harold Orr of the National Research Council, who jumped into the project at the request of the Saskatchewan Provincial Government after the OPEC oil embargo of 1973.“If we use six times as much insulation in the walls and ceiling and use much better windows and doors, we would be down to a total heat loss that is about 20 percent of the heat loss of a conventional house,” Orr wrote in a description of the project for this year’s Passive House Pioneer Award.“The trick is to attach the big wedges of pie first and then do your best on the smaller wedges. When we did this to the proposed SCH, we estimated that we could heat the house with a candle, a 45 Imperial gallon candle, and in 1976 about 33 dollars worth of fuel.”Using double wall construction and a carefully installed vapor and air barrier, the house tested at 0.8 air changes per hour at a pressure difference of 50 pascals, startling close to the current Passivhaus standard of 0.6 ach50.“We were just inventing the technique at the time,” Orr wrote, “and our subsequent designs have allowed much tighter houses down to 0.1 ach50.”Orr worked with Dumont for a number of years after the Conservation House was completed and said by telephone, “He was a very good friend. He had his funny streaks like everybody does, but he was very knowledgeable, and he kept up his knowledge, and was really strong telling people about how to build energy-efficient houses. He had the experience, because he built and owned two houses himself and also retrofitted another house.”Dumont also will be remembered for his work on the Factor 9 home, which he described in a 2010 article in Home Energy magazine. The house, built in Regina, Saskatchewan, was designed to use 90 percent less energy per square meter of floor area than an average existing home in Saskatchewan circa 1970.The house was insulated to R-80 in the attic, R-41 in above grade exterior walls, and R-44 on basement walls, and constructed with structural insulated panels. Windows on the south face of the house captured solar energy, and solar thermal panels provided space heating and hot water. Article on Factor 9 house.pdf UPDATEDRobert Stephen Dumont, a respected and well-liked researcher who helped create the essential elements for high-performance and net-zero energy building, died May 29 in Saskatoon, Saskatchewan. He was 69.Early in his career, Dumont was part of a team that designed the Saskatchewan Conservation House, a 1977 project honored this year by the Passivhaus Institut in Germany and an early forerunner to what became Passivhaus construction in Europe and the U.S.Far ahead of its time, the Saskatchewan Conservation House (Image #2, below) had far more insulation than a conventional house, triple-glazed windows, an insulated crawl space, and a very tight building envelope — all of the elements that builders now routinely use to reduce energy use.His own house in Saskatoon, built in 1992 and described in a 2013 GBA article by Michael Henry, had 16-inch-thick walls filled with cellulose, a drainwater heat exchanger, insulated hot water tank, and other energy-saving features, all in a very conventional looking package.Peter Amerongen, a builder in Edmonton who counted Dumont as an important mentor, visited the house in 2004 after deciding to “up our game” and venture into net-zero construction.“Basically, it was the formula we needed to follow,” Amerongen said of Dumont’s house. “And really, all we’ve done since then is tweak it, and take advantage of the new things that came along.” Praise from the Passivhaus communityKatrin Klingenberg, co-founder and executive director of the Passive House Institute U.S., said she never met Dumont but exchanged emails with him as she and others researched work of the 1970s and ‘80s that led to Passivhaus designs.“From what I could glean,” she wrote in an email, “among others he was instrumental to researching the underlying principles of passive houses and to formulating the core principles. I am deeply grateful for his work and contributions as it has made the work of the next generation, including my own, possible.”In a statement, the Passivhaus Institut praised Dumont’s contributions:“Today, we wish to express our high respect for his great commitment. Rob Dumont has not only contributed to the understanding of the main principles of sustainability. He also brought forward energy efficiency — the key to energy independence and the implementation of renewables and the universal approach everybody can take, regardless of if they are rich or poor in natural resources or if they construct buildings, vehicles or electronics.“The world needs people like Rob Dumont who understand this message, take responsibility for their actions and live for these convictions. We need people like Rob Dumont who know that life is about more than individual financial benefit. The contributions of Rob Dumont will live on forever — as long as there is a decent human society.“We convey our condolences to his family, friends and colleagues.” Remembered as a gentle manAmerongen, among others, remembered Dumont as someone steeped in the technical details of building science but who also made his points without rancor.“Whenever I wanted to do something new, I would run it by Rob,” he said, recalling a time when he was adamant about discontinuing the use of polyethylene vapor barriers in outside walls. “And he very gently told me he didn’t think it was a good idea to get rid of the vapor barrier in our climate.“It seems like he was right on in that regard,” Amerongen continued. “And so the first time he was very gently advising me not to do it, and then I took another passive house course and passed the exam and got heated up about getting rid of the vapor barrier, and the second time he was more forceful and basically told me not to be an idiot. He didn’t say it that way, of course, but that’s what I felt.“He was so incredibly observant and would always report his observations with this really gentle, matter of fact way. It was never about him. It was always about the information.”last_img read more

first_imgNicole Beck was an obvious choice as captain of the NSWCHS women’s team. A couple of months ago Beck got the call up to the National Women’s Open Squad and watching her play here at this tournament, it is not hard to see why. Getting the call up was something which she had dreamed of, and was not expecting it at all. Beck thought she hadn’t made the squad after missing out the initial on selection. “I was heaps shocked, but heaps happy too,” said Beck.Her talent shines here at this tournament, with skills that others are only just aiming to accomplish. But she believes that it is her commitment and determination in wanting to win that is her best attribute. “It’s my competitiveness, I hate to lose,” Beck said.Although Beck is not currently a part of the Australian Team to compete in the World Cup in South Africa next year, she is aiming to be a part of the following World Cup and will continue to strive for that goal. “I am just looking to keep learning and improving and hopefully in the future make the team,” Beck said. Beck’s message for the 750 athletes competing here this week who are looking to further their Touch career, is “keep going, set your goals high and keep your head up.”“I live by the motto: shoot for the moon because even if you miss at least you’ll land among the stars.”Influencing Beck’s Touch style is playing with and learning from players like Rachel Holden, and coaches like Tracey Bills. “I have been coached by Tracey Bills for about seven years and I have learnt a lot from her, actually almost everything,” Beck said.Beck’s NSWCHS team is now into the grand final against QSST and is hoping to repeat last year’s efforts, taking the title of under 18’s National Champions.last_img read more

first_imgAbout the authorFreddie TaylorShare the loveHave your say Man Utd legend Neville: Contract will help De Gea settleby Freddie Taylora month agoSend to a friendShare the loveManchester United legend Gary Neville says a new contract could see David De Gea return to form.The Spaniard hasn’t been himself this season, but Neville says a new deal until 2023 could settle the 28-year-old.Neville told Sky Sports: “De Gea has had a difficult time in the Premier League and he’s had difficulties at home where he’s lost his place in the national team. I don’t think he’s fully recovered from the poor World Cup in 2018, and he’s made more mistakes in the last 15 months than ever before.”But I’ve got to believe that this is good news and hope that what’s happened in the last 12 to 15 months has been a result of the ongoing speculation. The hope is that now he’s signed, he can settle down and start performing.”United need a spine. They had eight academy players in the squad on Saturday, but their problem isn’t the academy. The problem is that they haven’t got a strong, dominant spine, but De Gea can be the start of that.” last_img read more

Moodys German Ship Lenders to Require Further Provisioning

first_imgzoom German ship lenders are facing increasing risks from the prolonged global shipping industry crisis, with their exposure to the industry remaining significantly higher than that of their European and many global peers, according to a report from Moody’s rating agency.“We believe that Bremer Landesbank Kreditanstalt Oldenburg GZ (BremerLB), DVB Bank S.E. (DVB), HSH Nordbank AG (HSH), KFW IPEX-BANK GmbH (KfW IPEX) and Norddeutsche Landesbank GZ (NORD/LB) are the five German banks most vulnerable to a prolonged shipping downturn,” Swen Metzler, Vice President – Senior Analyst at Moody’s, said.“These banks face the risk of persistently high loan-loss provisioning, downward pressure on their profitability, and their ability to build capital,” Metzler added.Shipping exposures at these five German ship lenders still accounted for 350% of their Tier 1 capital at the end of 2015, up from 328% in 2012 and the aggregate problem loan ratio from shipping exposure for this group of banks rose to 30% in 2015 from 20% in 2012, about 3.5 times higher than their overall problem loan ratios.Moody’s said that ship leverage, measured as shipping exposure relative to Tier 1 capital, has also increased since 2012, except for HSH.“DVB’s exposure is now more than 12 times its Tier 1 capital, up from 9.4 times three years ago, with BremerLB at 4.7 times, up from 4.5 times,” Metzler said, adding that “for KfW IPEX and NORD/LB, leverage has risen to 2.7 and 2.3 times their capital.”Although HSH cut its shipping loan book and reduced its leverage, its exposure remained at EUR 23.9 billion as of year-end 2015, the highest in volume terms amongst German banks and 3.9 times its capital, according to the rating agency.In contrast, Commerzbank AG’s, UniCredit Bank AG’s, DekaBank Deutsche Girozentrale’s, and Landesbank Hessen-Thueringen GZ’s ship exposure, is less than their Tier 1 capital, and in aggregate, they have reduced their shipping exposure by around 45% between 2012 and 2015, Moody’s said.last_img read more
