Robert Dumont’s Superinsulated House in Saskatoon

first_imgThe first time I saw Rob Dumont’s house, I was unimpressed. I was visiting an ex-girlfriend in Saskatoon, I mentioned that I was doing some research into sustainable homes, and she said, “There’s one near here. We should walk by it.”It looked just like any other house. The Dumont house is in the colonial style. It’s simply built and doesn’t stand out in the neighborhood, which has a suburban feel to it (though it’s not far from the downtown). I’m used to seeing half-million dollar ecohomes. When you take away the architect and expensive finishes, solariums, thermal mass walls, radiant floors, etc., the Dumont house is hardly recognizable as an ecohouse.I arranged to go back later and visit Rob Dumont, who gave me a tour of his home and some other projects he was working on. What initially turned me off about the Dumont House (because it challenged my preconceptions) now makes it one of my favorite sustainable homes. “Always have your sails up”Rob Dumont, like many of the builders and designers I’ve met, started his work in the 1970s, and spent some time wandering (metaphorically) alone in the desert in the ’80s and ’90s.“Society has got a very short attention span,” he said. “There are waves of interest, but mother nature bats last. I started working in the ’70s on the Saskatchewan Conservation House. One had to really keep the faith through a part of the time since, because not many people were very interested. I must admit that back in 1973, with the oil shock, I thought the reasonable thing to do would be to change the way we do our houses radically. That was my youthful naïveté at the time.”He showed me a book of solar homes that was written in the late 1970s, a sort of hippie version of what I’m trying to do, and I realized that I’m just the latest emissary of societal interest, something Dumont has seen come and go. I feel like this time it may be different, but I’m not sure. “It’s encouraging,” said Dumont, but “it’s not nearly at the level I’d like it to be. E.F. Schumacher put it nicely: he said the wind may not always blow, but at least we should have our sails up. That’s the way I feel.”Rob and his wife Phil took me to see a college basketball game, in which the home team, the Huskies, thoroughly trounced the competition (both women’s and men’s teams). I pictured Rob in his younger days playing basketball, fit and idealistic, believing he could change the world. And he did – it just changes very slowly.I wonder, when I look back in another twenty or thirty years, how I will remember this time. As the beginning of real change, or as lost opportunity? All I know is that my visit with Rob Dumont left me more optimistic than when I arrived.

Michael Henry is a straw bale house builder who is curious about all aspects of green building, and blogs about it at The Sustainable Home. He’s also the author of Ontario’s Old-Growth Forests. There are about 16,000 pounds of cellulose in the house – but what makes this insulation system really special is that the two walls have very little framing between them, so there are far fewer pathways to lose heat through the wall, either through leakage where the insulation doesn’t meet the wood perfectly, or by thermal bridging through the wood itself.It may seem obvious, but it needs to be said: wood is way worse insulation than insulation is. A 2×6 stud wall with R-20 insulation batts has an overall insulation value of about R-13. Rob Dumont’s walls are R-60, the attic is R-80, and the windows are R-5. The whole house is carefully air sealed. It takes less than 1/4 of the energy to heat Dumont’s house that it would for a conventional house. (In 2000, Dumont wrote an article describing the energy efficiency features of his home.) The walls are 16 inches thickWhen Dumont built this house in 1992, it was recognized as one of the world’s most highly insulated homes – but the house, like Dumont himself, is understated. Dumont took the double-wall system from the Saskatchewan Conservation House, stretched it out to a full 16-inch-thick wall cavity, and filled this space with blown-in cellulose insulation (which is just recycled newspaper with borax added for fire proofing and pest control). Drainwater heat exchangerAs we continued the house tour, Rob showed me some things that really could be added to any existing house. The first was a drainwater heat exchanger, which is just a copper tube wrapped around the shower drain. As hot shower water comes down the drain pipe, the cold incoming water in the coil is warmed. “On a shower it will recover about half of the heat that’s otherwise going down the drain,” said Dumont.He quipped, “I’m worried that with the price of copper, in a home invasion someone will steal it.” Still, barring home invasions, the economic payback is pretty quick: if your hot water heater is electric, the heat exchanger will pay itself off in 5 or 6 years; with gas heater, maybe double that.Next we looked at the hot water heater itself, which is a standard tank but wrapped with batt insulation and a thermal blanket adding up to about R-28. “Without the insulation, it loses about 100 watts of heat continuously,” Dumont said. “With the insulation, it’s down to about 25 watts.”Because of the simplicity of the Dumont house, it wasn’t expensive to build. The insulation, upgraded windows, and solar thermal system added about 7% to the building cost. “If I’d put brick on the outside of the house instead of hardboard siding,” said Dumont, “the brick would have cost more than all of the energy conservation features. I’d much rather have an energy efficient house than a brick house.”In fact, the energy-efficiency measures (which cost $13,000) finished paying for themselves in 2008, after 16 years. Now the measures are turning a profit. And he pointed out other non-monetary benefits: no draftiness, no cold feet, and the nice aesthetic of the deep window ledges.last_img read more

Louisville Commit G.G. Robinson Says It’s “Messed Up’ That The Cardinals Pulled Their Offer From Matt Colburn

first_imgThe bad side of college football recruiting was showcased by Louisville Monday night, as the Cardinals pulled their scholarship offer from commit Matt Colburn, less than two days before National Signing Day. Bobby Petrino’s program received some serious criticism from recruiting analysts following the news, including this rant from a Rivals.com writer that called for all South Carolina high school players to boycott Louisville. Even a Cardinals’ commit thinks Louisville was rough on Colburn, a three-star running back out of Irmo, South Carolina. G.G. Robinson, a three-star defensive end committed to Petrino’s program, tweeted the following Tuesday morning. Man what Louisville did to my boy Matt was messed up….. That’s awful— GG (@GGRobinson85) February 3, 2015What Louisville did isn’t unheard of, but doing it less than 48 hours before National Signing Day seems fairly classless.

What The Hells Gotten Into Daniel Murphy

When theretofore ordinary second baseman Daniel Murphy turned into the reincarnation of Babe Ruth during last year’s playoffs, it was a fun story. Murphy was with the New York Mets through their lean, mediocre post-Madoff years, and he was suddenly the driving force behind their surprise World Series run. It seemed proof that in a handful of baseball games, damn near anything can happen.But for the sabermetrically minded (which presumably included the Mets’ front office), Murphy was still the decent-but-not-great player that his overall record said he was, and at age 30, he was likely on the downside of his career. So during the winter, the Mets moved on from Murphy to Neil Walker at second base — which, according to the stats, was basically the right call. Murphy signed with the Washington Nationals instead, and although projections suggested that he would have a solid season, there didn’t seem to be any way that he would build on his outlier postseason performance.Those projections have turned out to be flat-out wrong. Instead of reverting to his previous form, Murphy has looked an awful lot like the guy who went on that postseason tear: He currently ranks third in the National League in Weighted Runs Created Plus (wRC+)1A measure of a player’s runs generated per plate appearance, relative to the league, where average is 100 and higher numbers are better. and fourth in wins above replacement. (Murphy has also hit Mets pitching especially hard this year, delivering what already ranks as the most RBIs by a player against a team he played for the previous season since 1960.)For a guy who has never ranked higher than 37th in WAR, Murphy has taken a quantum leap forward. If Murphy maintains his current wRC+ for the entire season, it will be the 21st-biggest single-season improvement by a hitter over his previous career wRC+ at age 31 or older2With a minimum of 3,500 career plate appearances before the season in question and at least 350 plate appearances during the season itself. since 1901: Willie Stargell1971.398.628186.341.503134+52 PLAYERYEAROBPSLGWRC+OBPSLGWRC+WRC+ CHANGE Barry Bonds2002.582.799244.418.585164+80 Joe Morgan1976.444.576184.396.430138+46 Many of the people atop that list — including (but not limited to) Barry Bonds, Sammy Sosa, Ken Caminiti and Mark McGwire — have admitted to using performance-enhancing drugs, were named in the Mitchell Report or were otherwise implicated in baseball’s steroid scandal via leaked test results. But nothing so sinister has been mentioned to explain Murphy’s rise, and some players outside the steroid era experienced similar (presumably natural) leaps in performance.Murphy has always credited Mets hitting coach Kevin Long with making several key adjustments to his approach at the plate in an effort to help him hit for more power. Here’s Tyler Kepner of The New York Times last October, on Murphy’s swing changes:“Long believed Murphy should harness [his] power by driving more with his legs, moving closer to the plate, getting his front foot down sooner and bringing his hands lower and closer to his body.”The numbers bear this out: Murphy’s 2016 isolated power is 115 points higher than his previous career average, and he’s hitting the ball authoritatively in new areas of the strike zone. Murphy was always a solid hitter on pitches up and on the inner half of the plate, but his new approach has him driving the ball more on pitches in the middle of the plate and even ones low and away: Paul O’Neill1994.460.603171.341.443115+56 Ken Caminiti1996.408.621169.328.402102+67 Barry Bonds2004.609.812233.433.602171+62 Roy Cullenbine1946.477.537182.402.422132+50 Luis Gonzalez2001.429.688173.355.460114+59 Only includes players with a minimum of 3,500 career plate appearances before season and 350 in season.WRC+ = Weighted Runs Created PlusSource: Fangraphs Lonnie Smith1989.415.533166.362.401116+50 Of course, it’s still unlikely that Murphy has morphed into a hidden superstar after seven big-league seasons. Players in their 30s who improved on their previous career wRC+ by between 40 and 60 points in one season tended to lose 36 points of batting average, 38 points of on-base percentage and 80 points of slugging percentage the next year. But, on average, they were still better than they’d been before. Even a year after the initial breakout, they hit for a wRC+ 15 points higher than their career average had been beforehand.That means Murphy probably is a better hitter now than he was in New York. And considering the damage he’s already personally inflicted on the Mets in head-to-head competition, it also means he may well end up being the key to an NL East title for the Nationals. Not bad for a player most thought would turn back into a pumpkin after his Cinderella story last October.Check out our latest MLB predictions.
