AltaGas reaches agreement to export propane

first_imgCALGARY, A.B. – A preliminary agreement is now in place with a Tokyo based Liquefied Petroleum Gas importer and trader for the sale of half the propane that may be exported from a deep-water terminal northwest of Vancouver.Calgary based AltaGas says a deal is in the works with Astomos Energy Corporation which would buy at least 50 per cent of the one point two million tonnes of propane.AltaGas President David Harris says the long-term agreement is a major step forward in underpinning development of the proposed Ridley Island Propane Export Terminal, which would be Canada’s first propane terminal.- Advertisement -He also says, “This Export Terminal is one of the key building blocks of our strategy to build out natural gas processing and liquids separation capacity in the Montney Formation.”AltaGas, part owner and operator of a similar LPG export terminal in Ferndale, Washington, expects to reach a financial investment decision this year on the anticipated 400 to 500 million dollar terminal and commence commercial operation in 2018.last_img read more

Blackburn 0-1 Wolverhampton Wanderers: Wolves climb to eighth in Championship with hard-fought win

first_img David Edwards in action for Wolves 1 Wolverhampton Wanderers extended their unbeaten run to six games after a hard-fought 1-0 victory away to Blackburn.The win puts Wolves five points ahead of their hosts and sees them leapfrog Sheffield Wednesday into eighth place, while Rovers remain tenth in the Championship, one point ahead of Cardiff City.Kenny Jackett’s men had the better of the opening 15 minutes with Nouha Dicko twice going close after defensive errors by Lee Williamson and Tom Cairney respectively.Despite the early Wolves pressure, Blackburn began to gain a foothold on the game after 20 minutes with Ben Marshall heading a Jordan Rhodes cross just wide following good link up play.While, after 33 minutes, a long Marshall throw caused panic in the Wolves area before a controversial free-kick was awarded for a high foot by Edwards, although Wolves goalkeeper Ikeme saved the resulting strike.Following a quiet first half for both teams, the visitors put themselves in front almost immediately after the break. Dicko, a constant problem for Rovers, played Edwards through on the right of the penalty area and the Welsh midfielder made no mistake, steering it past Blackburn keeper Jason Steele into the bottom-left corner.The hosts almost equalised a few minutes later when Richard Stearman headed a Cairney cross against his own post but, other than this scare, Wolves continued to have the better chances with another Dicko shot hitting the bar, following good work by James Henry and Edwards, with 73 minutes gone .Despite a nervy final few minutes for Wolves, with fans singing Ikeme’s name after a couple of late saves, the visitors deservedly took all three points back to Molineux.last_img read more

Study: HB needs more firefighters

first_imgThe long-awaited 80-page analysis largely confirmed the Hermosa Beach Firefighters Association’s longtime claim that the department is understaffed and its members overworked, leaders said. “The report basically comes to the same precise conclusion that we’ve been asserting for years,” said union President Paul Hawkins. Divided into three shifts, 18 Hermosa Beach firefighters are supposed to work 10 24-hour stints a month, alternating two days on duty and four days off. The arrangement puts six firefighters on duty every day: three men in one firetruck, two men in a rescue ambulance and a single man in a second firetruck. But with a vacancy, two firefighters out with long-term injuries and another undergoing paramedic training, 14 men cover 18 positions. Increasing personnel levels to seven firefighters a day as recommended by the consultant would fully staff a second firetruck and more evenly spread the workload, Hawkins said. The city has estimated the change would cost about $505,000 a year, a figure that includes salaries and benefits for three new firefighters, as well as promotions for new captains and engineers. City officials hoped the study, commissioned in January, would put to rest persistent squabbling between management and rank-and-file over staffing levels. But discord within the department has seemingly settled after embattled fire Chief Russell Tingley retired in May. Jerry Gomez, the department’s retired assistant fire chief, is temporarily leading the crew while the city finds a permanent replacement for Tingley. The Hermosa Beach City Council is set to discuss the staffing study’s findings and any subsequent action next month. “The big question is does the city have the political and financial ability to fund it?” Hawkins said. “After going through all this pain and suffering and expense – to not do anything, that would be pretty irresponsible.” andrea.woodhouse@dailybreeze.com160Want local news?Sign up for the Localist and stay informed Something went wrong.

Adding a seventh firefighter to each of the department’s three 48-hour shifts, creating extra captains positions and bolstering the department’s reserve program are among the many recommendations from Matrix Consulting Group, which was paid nearly $30,000 by Hermosa Beach to examine the fire staffing levels. Here’s a quick list of some of the Palo Alto-based consultants’ other findings and suggestions: Immediately fill a now-vacant assistant fire chief position. The department provides “exceptional” response time for service, but with more than 2,200 calls a year, its demand is not “unreasonable.” Hire a dedicated fire prevention specialist, likely to cost about $78,000. FINDINGS: A seventh person should be added to each shift, and there should be more captains.

Leaping to Evolutionary Conclusions

Dominguez and Pasko Rakic, “Language evolution: The importance of being human,” Nature 462, 169-170 (12 November 2009) | doi:10.1038/462169a.It’s kind of funny watching the Darwinists go ape in their news stories.  They are desperately trying to shore up support for Darwin by showing that naturalistic science can do the job from the bottom up.  This has all the hallmarks of East Germany boasting the day before the Berlin Wall fell.  In spite of his collapsing economy, Honnecker was so confident of his ideology, he was planning a new high-tech fence that didn’t need guards to mow down its citizens wishing to escape to freedom; it could do the job automatically.  Before he knew what hit him he was history.    Look how Eugenie Scott is fighting little Ray Comfort with an arsenal of resources to overwhelm his little initiative to offer a little bit of Darwin-skeptical material to college students: she’s got a new Don’t Diss Darwin campaign to scare academia into action: “Creationism is coming to a campus near you.”  The campaign website even sells “Darwin: Evolve!” posters and other silly propaganda – posters, bookmarks and flyers.    Why the paranoia?  The Darwin Stasi know that once the wall is breached there is no going back.  Do your part to tear down this wall.  Work fast: if it falls before Nov. 24, the 150th anniversary of Darwin’s Origin, wouldn’t that be one for the history books: big party for has-been falls flat.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0 In classical science, researchers were reluctant to announce bold conclusions without sufficient data.  These days, it seems that science reporters are quick to announce sweeping conclusions that go far beyond the evidence – especially if they appear to support some sort of evolution.Planet magic crystal:  Where to find intelligent life?  Look for stars depleted in lithium.  That seems to be the implication of a story in the BBC News and Science Daily that extrapolated measurements of lower lithium levels from some stars known to have planets.  Maybe the aliens around those stars are using it for di-lithium crystals.  Clara Moskowitz didn’t even need the lithium.  Simple sunlike stars “May be Cosmic Road Signs to Intelligent Aliens,”  she announced on Space.com.  To her, this is all very logical: “The distinction between habitable planets and planets harboring intelligent life is based on the fact that intelligent life requires stars with lifetimes greater than the time required for intelligence to evolve,” she said.  “For example, in the case of this solar system, we could not find ourselves around a star with a lifetime less than 4.5 billion years.”  No other source for intelligent life than blind, purposeless evolution was entertained as a possibility.Cool earth:  Science Daily leapt from a Stanford study of isotope ratios in rocks said to be 3.4 billion years old that the earth was cooler a billion years earlier than thought, and therefore life must have evolved earlier than thought.  “Their findings suggest that the early ocean was much more temperate and that, as a result, life likely diversified and spread across the globe much sooner in Earth’s history than has been generally theorized.”  How one gets from isotope ratios to life was not clear.Origin of life:  An article in Science Daily is accompanied by a picture that looks like a scene from Frankenstein.  Researchers at NASA-Ames are zapping ice with ultraviolet light.  The headline announces, “NASA Reproduces A Building Block Of Life In Laboratory.”  What really happened was that they made uracil (one of the pyrimidines in RNA) under highly specialized conditions.  It’s not really news, anyway; Jonathan Sarfati on Creation.com wrote about this 10 years ago.  Nevertheless, one of the researchers fired a conclusion heard round the universe: “Since we are simulating universal astrophysical conditions, the same is likely wherever planets are formed.”  They speculated that UV light shining on ices could have formed the uracil in comets, but did not explain how the “whimpy” [sic] molecules would have survived re-entry or concentrated in significant amounts to do any good.Plant charity:  PhysOrg reported on work on the yellow jewelweed.  Experiments show that it recognizes kin from non-kin and adjusts its growth accordingly.  Conclusion: “This study demonstrates that plants are social organisms.  It shows that altruism is possible among plants and that response to both kin and strangers depend on the ecology of the plant species.”  When they find plants donating to the Red Cross, they’ll really be onto something.Missing dino link:  The BBC News announced, “Missing link dinosaur discovered.”  It’s a sauropod that the discoverers infer walked on two legs most of the time but occasionally walked on all fours.  But then the article added that it lived in the early Jurassic.  “Although structurally it’s intermediate, it lived too late to be an actual ancestor, because true sauropods already existed [then].”  Now it has to be described as an extinct “living fossil” (an oxymoron) because “the transition” (for which there is no evidence) “must have happened much earlier.”  Science Daily was only slightly more reserved, announcing Darwinly, “New Species Of Vegetarian Dinosaur Close To Common Ancestor Of Gigantic Sauropods.”Dino sweat:  Speaking of dinosaurs, PhysOrg reported on a comparative analysis of dinosaur body types.  The scientists inferred that some of them must have been warm blooded because if not it would be hard for them to function.  The headline: “Warm-blooded dinosaurs worked up a sweat.”  The article also claimed that this demonstrates that warm-bloodedness (endothermy) “evolved” earlier: “This pushes the evolution of endothermy further back into the ancient past than many researchers expected, suggesting that dinosaurs were athletic, endothermic animals throughout the Mesozoic era.”  No fossil dinosaur pole-vaulters were discovered.Bird philosophy:  Some songbirds appear to use sets of syllables in their songs.  PhysOrg jumped into a discussion of “The Link Between Birdsong And Human Language.”  Maybe there is more scholarship in those tweets than we thought.Talking genes:  Most popular science outlets were abuzz today about a paper in tomorrow’s Nature that discussed more research into the FOXP2 gene and its complex interactions with motor actions.1  The paper was reserved in its implications, as was the review by Dominguez and Rakic in the same issue,1 which said of the work by Konopka et al, “it answers many questions, but raises even more.”  You wouldn’t know that by looking at the Live Science headline, where Jeanna Bryner announced triumphantly, “Human Speech Gene Found.”  PhysOrg followed suit, saying, “Why can’t chimps speak?  Study links evolution of single gene to human capacity for language.”  New Scientist was a little more careful, saying in its headline, “Suite of chatterbox genes discovered.”  It should be noted that no gene can create language (in terms of semantics, syntax, and abstract thought).  What has been found is that mutations to the human FOXP2 gene cause serious problems with speech because the motor neurons involved in talking are affected.last_img read more

Choosing a Cost-Effective Wall System

first_img GREEN PRODUCT GUIDE Board Insulation“I built a double-stud in 1980 and have never regretted it,” Klingel writes. “New house will be the same, but thicker, and with dense-packed cellulose instead of fiberglass.”“A double stud with a plywood exterior and interior poly and ADA [the Airtight Drywall Approach] will work,” Rooks says.GBA senior editor Martin Holladay doesn’t push the double-stud option, but he does point Olofsson toward a number of GBA articles that have been written on the topic (see the “Related Articles” sidebar). Deciphering Canadian codesMalcolm Taylor writes that the British Columbia building code allows an “airtight drywall air barrier” instead of polyethylene. “Illustrated details covering all aspects of the approach can be found in the Building Envelope Guide for Houses published by the Homeowner Protection Office, which is a Provincial Government department,” he says.But to Holladay, there seems to be some confusion in the codes over the roles that air and vapor barriers play in a wall assembly. “I can’t help but shake my head at the inconsistency in the BC code,” Holladay says. “Do code officials think that polyethylene is a vapor retarder or an air barrier? If they think it is a vapor retarder, then the Airtight Drywall Approach is no substitute. To retard the flow of vapor, you need vapor-retarder paint. The airtightness of the drywall is irrelevant.“If they think it is an air barrier, I wonder whether they require airtight installation details for all installations of poly in the province? For example, do they verify that the poly seams are sealed over framing members with Tremco acoustical sealant? Do they verify that all electrical boxes are airtight boxes? If they do, bless them. However, I doubt that they do. I think it’s far more likely that the building inspectors have no idea whether the poly they insist on is supposed to be a vapor retarder or an air barrier.”Taylor says he can’t speak to how the code is enforced in the province as a whole, but at least on Vancouver Island and the lower mainland, inspectors “insist on meticulously sealed poly.”“All seams, the joint between poly and lower plate and plate and subfloor all must have generous amounts of acoustic sealant,” he says. “Gasketed electrical boxes are also required.”In Ontario, adds Lucas Durand, there’s apparently a little more flexibility. “For the house that I am building for myself,” he says, “I have gone with taped 1/2-in. plywood for both air barrier and vapor retarder (and racking resistance). There was some initial skepticism from my inspector but it didn’t take that long to convince her — I am lucky she has been open-minded.” Creating sensible regulationsSome of the material in the Canadian publication gives Holladay reason to wonder whether government officials really understand the science behind code requirements. “As is often the case,” he writes, “this is an example of government bureaucrats enforcing regulations that are based on an incomplete understanding of the relevant scientific principles.”While that could very well be true, Olofsson’s potential tussle with local officials could have an upside. “The nice thing about your questions is that it is exposing that you can move the envelope quality in your area forward,” Rooks says. “The code seems to allow enough room for well planned modification. Lucas points out a few more methods towards improved assemblies. They are all great when executed correctly.“There is no shortcut to a ‘quality envelope.’ Plan on it being more cost and work. I think it’s the only sensible thing to do.” Erik Olofsson is planning a small house in the Rocky Mountains of British Columbia. Ideally, he’d like to get the walls close to R-40. The question is how.“Seeing that the received opinion around GBA is the tandem of polyethylene sheeting and exterior rigid foam is not ideal, what do the builders on this site recommend?” he asks in a post at the GBA Q&A forum. “Larsen trusses seem fairly labor-intensive and rigid foam is expensive … Is a double-stud wall the answer?”A complication is a local building code that apparently calls for a polyethylene vapor barrier on the warm side of the insulation. Although once a common building technique, it’s no longer universally accepted by building scientists as the best practice in all climates. Many builders have abandoned the use of interior polyethylene, even as some building inspectors continue to insist on it.Olofsson’s quest for high performance at a reasonable cost, while solving the riddle of air and vapor barriers, is the topic of this month’s Q&A Spotlight. Our expert’s opinionHere’s how GBA technical director Peter Yost sees it:The reason Martin Holladay and I nearly always agree on building science questions is that we both have studied under/worked with some of the best: Joe Lstiburek, John Straube, Terry Brennan, Bill Rose, Anton TenWolde.And one of the reasons there is still such confusion on basic heat transfer and moisture flow is that too many building inspectors and code officials have not.Is this silly or what?The highest priority in moisture management is bulk water: how many building inspectors check the connections between the water-resistive barrier and flashings at penetrations for continuity?The next highest priority in moisture management is capillary water: how many building inspectors check for capillary breaks between porous building components?The next priority is air-transported moisture: how many building inspectors require qualitative and quantitative information from blower-door tests?But by gosh, almost every building inspector insists on and inspects the “warm-in-winter-side” vapor retarder, by far the least important wetting mechanism in nearly all buildings and climates.And we should not be worried about the vapor permeability of just that one dedicated layer in terms of wetting, but the vapor permeability of ALL layers in terms of drying. (For more information, see my Vapor Profile blog.)GBA has a series of great resources on vapor retarders and air barriers and their differences. Use your GBA project folders, make one for your building inspector(s), and fill it up with building science reading for them! RELATED ARTICLES center_img Double-stud walls a good optionDouble-stud walls are designed to provide lots of exterior wall volume for insulation while sharply reducing thermal bridging. John Klingel and Albert Rooks are among those who think that building double-stud walls is a good approach. RELATED MULTIMEDIA Or consider 2×6 framingRooks also offers an alternative for Olofsson to consider. “Another good quality wall is a 2×6 standard frame with taped plywood or OSB exterior + WRB [water-resistant barrier] + 4 in. to 6 in. of high-density mineral wool,” he says. “It will eliminate cold sheathing and rim-joist bridging while allowing the use of a service cavity in the stud bays.”A key detail of all of these recommendations is that a polyethylene vapor barrier isn’t necessary. In the case of the wall assembly suggested by Rooks, the OSB or plywood sheathing becomes the “air/vapor control layer.”“Use a rainscreen detail, good air sealing, and ventilation,” Rooks adds. “I’m a fan of mineral wool because it doesn’t settle, doesn’t rot even if continually wetted, is fireproof, won’t support mold or bugs. It’s like a little piece if the Canadian Rockies (since it’s made of Canadian Basalt) covering your house, and near as durable.”Holladay, too, think there are alternatives to the polyethylene required by local codes. “You might want to negotiate with your local building inspector,” he says. “Many inspectors will accept MemBrain or vapor-retarder paint as an alternative to interior poly.” Podcast:Air Barriers vs. Vapor Barriers Double-stud wallsChoosing a High-Performance Wall AssemblyChoosing the Right Wall Assembly (2013)Choosing the Right Wall Assembly (2015) Is Double Stud-Wall Construction the Path to Efficiency on a Budget?Vapor Retarders and Vapor BarriersForget Vapor Diffusion — Stop the Air Leaks!

Seizing an Air-Sealing Opportunity

first_imgThe number one thing you need to do to protect a building is control water. As the Canadian building scientist Gus Handegord said, “The three biggest problems in buildings are water, water, and water.” So, with the 1961 house I bought this year, one of the first things I discovered was the failure at the edge of the roof. The gutters weren’t working well, resulting in water getting into places it shouldn’t be and rotting out the soffit and fascia boards in multiple places around the house.Last week, we had a contractor out to begin fixing the water problem by replacing the soffits, fascias, and gutters. The first step, of course, was removing the old stuff.  And that’s when an air-sealing and insulating opportunity arose for me. Let’s take a look.What is behind those boards?When the soffit space was opened up, I learned a few things. First, the sheathing behind the brick veneer on our 1961 house is gypsum board. I was expecting asphalt-impregnated fiberboard, like I found behind the brick veneer on the 1970 condo I owned before moving here. That gypsum raises a host of questions that I won’t explore here, but the second thing I learned is that the electricians took the easy way out because of this material choice.In the photo below, there are two wires coming from the attic, going across the top plate, and then into the wall through a hole punched in the gypsum. Hey, it’s a lot easier to knock a hole through gypsum than drill through three inches of wood top plates, right? In addition to the wire holes, the gypsum sheathing, which is where the continuous air barrier should be, was broken in other places, too. See that big hole between the two wires?Air leakage sites behind the soffit and fascia.The third thing I learned is that when spray foam installers are encapsulating an attic, they can miss insulating and air-sealing over the top plate of the exterior wall. I wrote about this problem in my article last week. The photo below shows what happens.The spray foam installer can’t get a good angle to make the foam stick in that open gap and they usually don’t put blocking in there. So the foam overshoots the gap, which is clearly evident below. Note the spray foam shadow where the end of the ceiling joist is. (See that article, Spray Foam Insulation at the Edge, for more details.)Air leakage sites in the sheathing and at the top plate.Also to be noted in the photo above is the seam between the pieces of gypsum sheathing. There’s no tape or other kind of sealant to cover that gap, so there’s another place that air can go into or out of the walls.How to fix itSince this attic is encapsulated with spray foam, the solution is easy. I got myself a couple of two-part foam kits (photo below).Two-part foam kit for sealing and insulating.The next photo shows one of the rafter bays after spraying. I did three things there:Filled the end of the cavity with foam. That provided insulation over the top plate of the exterior wall and sealed any penetrations in the top plate as well as the gap between the top plate and ceiling drywall.Sealed the top edge of the gypsum sheathing.Sealed the seam between two sheets of exterior sheathing.There were no cable penetrations in this bay, but I sealed those up wherever I saw them, too.Spray foam from a two-part foam kit sealing and insulating the sheathing and the top plate.If I were dealing with a vented attic instead, things would have been more difficult.  I still would have sealed all the seams, edges, and penetrations in the gypsum sheathing, but I wouldn’t have filled the rafter bays with spray foam. That would eliminate venting from the soffits. To keep the attic vented and get the top plate sealed and insulated from outside would be important but tricky.  I’m interested to hear what others have done in that situation.Understanding the air barrierWhen the contractor’s workers got the first part of the soffit opened up, I missed some of the sealing. I had a foam gun and three cans of foam as well as a two-part foam kit, but that first kit didn’t work. I did the best I could with the gun, but it wasn’t up to the task. It killed me to do it, but I had to leave about 20 feet of the rafter bays and sheathing incompletely sealed and insulated.I was talking to the contractor and lamenting having to watch his workers cover up that one part of the house without sealing it up first. He said, “That doesn’t matter. It’ll be sealed up once we put the soffits and fascias back up there.”He’s a smart guy and does really good work. He doesn’t often have to think about where the air barrier is, though. In this case, what he said was incorrect because that space in the soffit is connected to other places. It’s connected to the vented attic over the garage. The fascia isn’t sealed at the top edge, which will be covered—but not sealed— by the drip edge. The soffit and fascia are not the air barrier.With the soffits and fascias replaced, that part of the air barrier is again inaccessible.The soffit crew is just about done with installing the new stuff. The photo above shows the front of the garage. Soon we’ll have the painters come do their thing and then have the soffit company come back and install the new gutters. At that point, we will have made a big stride in solving the problems of water, water, and water. And I snuck in and helped with the problems of air and heat, too!Allison Bailes of Decatur, Georgia, is a speaker, writer, building science consultant, and the author of the Energy Vanguard Blog.
