  • Tennis Canada coach says ‘sky is the limit’ for Bianca Andreescu

    first_img“The sky is the limit for her, it really is. I am saying now she will probably make the WTA Finals and a Grand Slam, maybe.  “With a good draw, some luck and with what she has shown last week, you don’t want to put too much expectation on her, but she was not expected to win Indian Wells and look what happened.”A Grand Slam might be next year, but you just don’t know. She has incredible determination and drive. She will stay grounded, there will be no issue with that and she can achieve so much.” Bianca Andreescu visualized unlikely Indian Wells win: ‘A Cinderella story’ Bianca Andreescu’s former coach Andre Labelle says the teenage sensation can win a Grand Slam this year after her astonishing Indian Wells Open triumph.Andreescu made history on Sunday by beating three-time major champion Angelique Kerber 6-4, 3-6, 6-4 to become the first wild card to win the prestigious title in California. The 18-year-old Canadian started the year outside the top 150, but rose to 24th on Monday after seeing off the likes of Garbine Muguruza and Elina Svitolina before stunning Kerber.From a wild card to the Indian Wells champion – Bianca Andreescu just made history. Congratulations, @Bandreescu_! #BiancaRising 🎾🇨🇦 https://t.co/0IBTOfcZQH— Justin Trudeau (@JustinTrudeau) March 18, 2019Labelle, who nurtured Andreescu’s talent for almost four years at Tennis Canada, believes the rising star’s first WTA Tour triumph will most definitely not be a flash in the pan. Related News “Before Indian Wells, the goal for Bianca was top 50 at the end of the year,” the Tennis Canada national coach told Omnisport. “So now obviously that will be changed.

  • Half-time: Middlesbrough 0 QPR 0

    first_imgGreen is in the final year of his contract at QPRQPR, playing without a recognised striker in the absence of Charlie Austin, made it to half-time on level terms thanks to a miss from David Nugent and some resolute defending.Middlesbrough forward Nugent nudged the ball against the post after being set up by Albert Adomah.Earlier, Nedum Onuoha produced a terrific last-ditch challenge to deny Nugent and Diego Fabbrini then blasted over the Rangers bar.Austin has been nursing a slight calf problem and interim boss Neil Warnock also missed the game at the Riverside Stadium, for personal reasons, leaving Kevin Blackwell in charge.Rangers have defended in numbers and posed very little threat at the other end of the pitch, with keeper Dimi Konstantopoulos easily able to deal with long-range efforts from Leroy Fer and Sandro.Konstantopoulos was at least tested by a firmly-struck free-kick from Alejandro Faurin, which he managed to punch away, before the lively Fabbrini fired wide in the final seconds of the half.QPR: Green, Perch, Onuoha, Hall, Konchesky, Phillips, Henry, Sandro, Faurlin, Yun, Fer.Subs: Smithies, Angella, Luongo, Toszer, Petrasso, Blackwood, Emmanuel-Thomas.Follow West London Sport on TwitterFind us on Facebooklast_img read more

  • Q&A Spotlight: Will One Radiant Floor Heat Two Stories?

    first_imgOne of the houses had double-glazed windows, “not huge R-value,” very good solar orientation and a sprawling layout. Radiant-floor tubing was extended to the second floor, but after two winters the client had no interest in second-floor heat distribution.The other house was much tighter. Here again, heat in only the first-floor slab was enough to keep the house toasty.“I essentially agree with Martin, though, only disagreeing in what the threshold might be,” says Kolbert. “An energy model (and someone who knows what to do with it) would help make the decision.”Robert Riversong, however, isn’t so sure it’s going to work.“Unless your house is very energy efficient (32,000-45,000 btu/hour maximum design load), then a single floor won’t be able to comfortably heat an entire house, and you won’t get the radiant comfort advantage on the non-radiant floors,” writes Robert Riversgong. “In fact, a cool concrete/stone/tile floor will be quite uncomfortable.“All floors should be heated, and the radiant design is critical to effectiveness, efficiency and comfort,” he says. “Get yourself a heating contractor who understands this and who is willing to do the calculations necessary to design an appropriate system.”Keeping feet warmPeople like radiant-floor heat because they think it will keep their feet warm all winter, even when the heat isn’t cranked up.That, at least, is the perception. But NickJ reports the reality can be a little different.“My wife wanted warm feet,” Nick writes. “So we installed radiant in our main floor slab and upper wood floors.”The system keeps the house warm enough, no problem there. But for the heat to be perceptible on the bottom of their feet, Nick adds, “you’d be baked out of the house.”“There is a widespread misunderstanding that a radiant floor needs to be hot in order for feet to feel warm,” Riversong replies.“With shod feet, 90% of people report comfort with a floor that is between 66°F and 84°F, and with bare feet a floor between 79°F and 84°F. Your feet (and most of your skin) are typically 91.4°F, so nothing less than that temperature is going to add heat to your feet.”With bare feet, he adds, the conductivity and specific heat of the flooring material is more important to comfort than the temperature of the floor.Whole-body temperature is as much dependent on the “mean radiant temperature” of all solid materials in the room as it is on air temperature. That’s why, he says, radiant heat feels comfortable even at lower temperatures.But the second floor still won’t be comfortable if only the basement slab is heated.Do the calculationsOne bedrock principle of energy-efficient building is not to hire heating contractors who insist on using a seat-of-the-pants method to calculate a home’s heat load. The best way to calculate a home’s heat load — the first step to designing a residential heating system — is to perform a Manual J calculation, a method promulgated by the Air Conditioning Contractors of America.Scholau’s architect thinks the one-floor heat plan will work, but his wife is skeptical; so Schonlau asked a heating contractor to run a Manual J calculation. The contractor said he could do it, but apparently commented that the calculation might as well be used for toilet paper for all the help it would provide.“Should I keep looking for HVAC contractors who will do it or is there a better approach?” he asks. “I’d like to know what the heating and cooling loads are up front, so I can better educated about choosing equipment.”It would probably be best to find a different contractors, says Holladay. “As I’m sure you know, I’ve written that many Manual J analyses are done poorly, and a Manual J calculation is not the be-all and end-all to HVAC system design,” Holladay says. “But to dismiss Manual J entirely shows a remarkable lack of sophistication, so it calls all of the contractors’ promises into doubt.”Armando Cobo writes that a better assessment would come from “Manual GAMA-H-22.” Presumably, GAMA refers to the Gas Appliance Manufacturers Association, a trade group representing manufacturers of gas-fired water heaters, furnaces, and boilers. Using that standard, Cobo says, a qualified, independent mechanical engineer should be able to analyze the house and recommend a way of heating it. Manual J, he says, is used to calculate heating loads, while H-22 is used to design hydronic systems.Although David Meiland says he’s rarely seen a third-party mechanical designer on residential jobs, Michael Chandler suggests it’s not so odd.“Our Energy Star and Green Rating provider (Southern Energy Management) handles all our Manual J and HVAC system design with their in-house mechanical engineer,” Chandler says. “They don’t do it for free, but it’s a great service and gives us really useful data on our assumptions and actual performance and helps us make changes to move our quality in a positive direction.He suggests Schonlau check with his Energy Star provider. “[There’s] a good chance they can connect you with an engineer who can take it our of the HVAC installers hands,” he writes. “I haven’t had my HVAC installer do his own Manual J for years.”Expert opinionWe asked Peter Yost, GBA’s technical director, for his opinion. Here’s what he had to say:There are really two distinct issues here:1. Can you pump enough BTUs through the basement “radiant” floor system to offset the home’s total heating load?That is the type of question that ACCA Manual J can answer and I don’t doubt that Michael Schonlau can get this calculation done correctly by an energy rater or top-notch HVAC contractor. I also suspect that he can do it without Passivhaus adherence to building envelope performance, but we don’t know any details of the home’s design or siting, so it’s very hard to say with as little information as we have.2. Can the basement “radiant” floor system maintain thermal comfort throughout the home?Manual J certainly won’t help us here. And this is an even harder question because it involves real people with lots of individual perceptions of thermal comfort that ASHRAE Standard 55 wraps up into percentages of large numbers of people satisfied and dissatisfied. We heated homes here in New England for many years with “gravity” distribution systems where grates and passive convection accomplished distribution, but accomplished may be a real stretch if you were to ask folks with these systems. Admittedly, none of those old New England farm houses were or are even in the same universe as Passivhaus.My main point: This is a design questionHow heat generated in the basement will effectively make its way up to the second floor is a design question, probably best attempted by computational fluid dynamics (CFD) analysis. But CFD is not in any HVAC contractor’s or energy rater’s tool boxes that I know.Radiant floor heating may not be best for this situationAnd if I were going to heat one floor, I don’t think I would choose a system with such a low and slow rate of heat exchange as a radiant floor system. It’s hard for me to imagine this system not lagging far enough behind changing outdoor conditions that the home would not be swinging between under- and over-heating in all the spaces, but certainly the basement. And forget any setback strategies.So, can it be done? Absolutely. Will the occupants and their guests be comfortable throughout the heating season? I honestly don’t know but am skeptical. It it were my house, I would be designing in a Plan B to boost the second floor.Terminology technicalitiesFinally, you may be wondering why I have twice put the term radiant in quotation marks when used in the phrase, radiant floor heating. At best, 60% of any hydronic floor heating system is radiant heat transfer. And up on the second floor of this home, it won’t be anywhere near 60%. It will be the air temperature and convection that drive heat distribution with a distinct lack of the cozy “warm toes” phenomenon. RELATED ARTICLES Energy Solutions: Radiant-Floor HeatingMusings of an Energy Nerd: Heating a Tight, Well-Insulated HouseLessons Learned the Hard WayMusings of an Energy Nerd: Saving Energy With Manual J and Manual D Q&A: Sizing HVAC Equipment Michael Schonlau is building a house in Omaha, Nebraska, where he can expect 6,000+ heating degree days a year. He’s planning on putting a radiant-floor system in the basement slab of the ranch-style home with a footprint of about 1,600 sq. ft.In a recent posting on GBA’s page, Schonlau asked whether he’ll have to install radiant loops under the subfloor of the first floor as well as the basement — or will the heat generated in the basement migrate upstairs and keep the house comfortable?“Please assume the house will be well-insulated and air sealed, with ‘good’ windows,” he wrote. But will that be enough to keep his wife’s toes warm through a long Nebraska winter?It’s been doneGBA senior editor Martin Holladay tells Schonlau it can be done, but “but only if you aim for near-Passivhaus levels of airtightness, insulation, and window quality.”Dan Kolbert is more optimistic.“We’ve built a couple of houses on slabs with no heat distribution on the 2nd floor,” Kolbert says. “They were good, but certainly not Passive House.”last_img read more

  • Grading the Installation Quality of Insulation

    first_imgThe two criteria for assigning the gradeWhen the HERS rater is inspecting the insulation installation quality, they look at two criteria:Missing insulationCompression and incompletely filled areasMissing insulation. When a cavity in a building assembly has insulation installed in a way that leaves gaps, that affects the amount of heat that flows across the building envelope. More heat will pass through assemblies that have gaps. (If you want to see just how much a little bit of missing insulation can hurt performance, check out this calculation for a ceiling with an uninsulated attic hatch.) The more gaps there are, the worse the grade it gets. Here’s how the HERS Standards relate missing insulation to grade:Grade I: “Occasional very small gaps are acceptable.” In another place, the Standards say, “if the exterior sheathing is visible from the building interior through gaps in the cavity insulation material, it is not considered a ‘Grade I’ installation.” Grade II: Up to 2% missing insulationGrade III: Between 2% and 5% missing insulationIf you’re wondering what happens when you do an inspection and find that more than 5% of an assembly is missing insulation, the answer is that you have to break out the uninsulated part and model it separately. If it’s new construction, you’ll probably be telling the builder to finish insulating, but in existing homes, sometimes you have to model the uninsulated part.The illustration below (image #3), taken from the HERS Standards (Appendix A, pages A-11 to A-16), shows visually what the rater should be looking for.Compression and incomplete fill. Compression is a common problem with fiberglass batt insulation because the batts are often not cut to the proper size for the cavity.Grade I: Up to 2% of the area can have compression or incomplete fill. If a spot is incompletely filled, it must be depleted no more than 30% to attain Grade I. In other words, no more than 20 square feet of each 1000 square feet can have this problem, and even those 20 square feet must be filled to at least 70% of their intended depth.Grade II: Up to 10% of the area can have compression or incomplete fill and again must be filled to at least 70% of their intended insulation depth.Grade III: Unspecified. I take this to mean that any compression or incomplete fill that lies outside the bounds specified for Grade I or Grade II would garner that assembly a Grade III.The illustration below (image #4), again taken from the HERS Standards, shows what these conditions would look like. Making the gradeMost of the time, assigning a grade to an insulation installation isn’t really so hard. Sometimes, you look at it and see immediately that it’s Grade I. Other times, it’s immediatley obvious that it’s Grade III. The difficulty comes in when you’re on the boundary between I and II or between II and III. That’s when you might need to dig a little deeper and get out your measuring tape. If you want to learn more about this, download a copy of the HERS Standards (link below) and read pages A-11 through A-16 in Appendix A. If you’re a home builder or insulation contractor working with HERS raters, it’s important to know exactly what they’re looking for.Putting a grade on the installation of insulation and doing inspections before drywall goes into new homes were two of the biggest changes that RESNET and ENERGY STAR introduced six years ago. New homes that have gone through this process have gotten a lot better as a result. GBA Encyclopedia: Batt and Blanket InsulationInstalling Fiberglass RightHow to Install Cellulose Insulation Download the HERS Standards: 2006 National Mortgage Industry Home Energy Rating System Standards (pdf) A home energy rating includes energy modeling to see how energy efficient a home is or will be. Most HERS ratings have been done for new homes that are seeking to qualify for a program’s label or certification, such as the ENERGY STAR new homes program. The rater gathers all the information about the building envelope, the heating and cooling systems, ventilation, water heating, lights, and appliances. The data go into the energy rating software, which does the calculations and comes up with estimated annual consumption and costs as well as a number called the HERS Index.center_img The three grades: I, II, and IIIThe R-value of the insulation in all the insulated building assemblies (walls, ceilings, floors) can have a big effect on the results. Now that raters put a grade on the installation quality, it helps the rater develop a more accurate energy model of the home. When a rater goes in and looks at the insulation, they’ve got to record each assembly as having a Grade I, Grade II, or Grade III insulation installation quality.Note: This protocol applies to all types of cavity insulation, not just fiberglass batts. Spray foam, cellulose, and mineral wool can all be installed with gaps, compression, and incompletely filled areas, and they can all be installed well.Grade I is the best. This means that the insulation is installed according to the manufacturer’s instructions. It completely fills the cavity in the case of air-permeable insulation and also is encapsulated on six sides (with an exception for IECC climate zones 1-3). It’s cut around electrical junction boxes, split around wires and pipes, and generally not compressed.Grade II is second best. There’s some allowance for imperfections in the installation but overall, it’s still not too bad. The HERS Standards say a Grade II installation can have “moderate to frequent installation defects: gaps around wiring, electrical outlets, plumbing and other intrusions; rounded edges or “shoulders”; or incomplete fill…”Grade III is the lowest grade. It has “substantial gaps and voids.”The energy rating software models these three grades differently. When the rater enters Grade I, the software calculates according 100% of the cavity insulation having the R-value entered. When the rater enters Grade II, the software models the cavities as having 98% of their area insulated to the given R-value and 2% uninsulated. For Grade III, 95% of the cavity area is calculated with the given R-value and 5% is treated as uninsulated. (The reason for these particular numbers should become clear to you below.) Six years ago, RESNET published a major revision of the HERS Standards, officially named the 2006 Mortgage Industry National Home Energy Rating Systems Standards. One important new feature in the standards was the grading of insulation installation quality. Before this change, R-13 insulation installed poorly (as shown in the second photo, below) was equivalent to any other R-13 insulation, including insulation with impeccable installation quality (as shown at the top of this article).If you know any HERS raters, you’ve probably heard the debates about the various types of insulation and the poor quality of installation they sometimes see. (OK, you’re right; it’s more than just an occasional sighting.) In fact, the Green Curmudgeon’s suggestion that maybe we ought to consider banning batt insulation has generated a discussion that won’t die.So, how exactly does this system of grading the installation quality of insulation work? Raters have been doing it for six years now, so it’s time for the rest of you to find out what they’re doing.

  • Sachin Tendulkar deserves Bharat Ratna: Dhanraj Pillay

    first_imgFormer hockey captain and Olympian Dhanraj Pillay on Wednesday joined the increasing chorus of voices demanding that batting maestro Sachin Tendulkar be given the ‘Bharat Ratna’ by the Indian government. “Sachin certainly deserves to be conferred the Bharat Ratna for the way he has been playing for the last 22 years. He was the mastermind of our World Cup victory,” said Pillay, who has represented India in four Olympics and hockey World Cups. Pillay, who spoke on the sidelines of the function to release veteran photographer Mohan Bane’s pictorial book on the Beijing Olympics with English captions, The Gold Wall of India, also believed that Tendulkar should play in the next World Cup in 2015. “He’s as fit as a 19 or 20 year old and he should play in the next World Cup too,” said Pillay about Tendulkar who would be turning 38 on April 24. Union Energy Minister Sushil Kumar Shinde also said Tendulkar deserved to be honoured with the Bharat Ratna. “Just like Donald Bradman, Tendulkar has brought happiness to the cricket fans of the world with his batsmanship. He deserves to be conferred with the Bharat Ratna,” said Shinde who was among the dignitaries present at the book release event. With inputs from PTIlast_img read more

    first_imgACT / Country have thrown out an ominous warning to their rivals after three days of competition at the 2008 Australian Defence Touch Association (ADTA) Nationals at Williamtown.Led by new ADTA Hall of Fame inductee, John Samin, the ACT / Country Men’s 30’s playing in the Men’s Open competition have not dropped a game as yet. ACT / Country’s biggest threat will be from the second placed Sydney Metros A line-up including Manu Wakely.The ACT / Country Women’s Open also have a shot at the title but favouritism lies with defending champions, North Queensland. North Queensland have been an attacking force throughout the tournament with Emma Wood being a major recipient having crossed for ten touchdowns in her first four games. The Barbarians have made a late charge for the title upsetting North Queensland and Sydney Metros after previously not winning a game in the tournament. The ACT / Country Men’s 30’s are also looking to defend their title won last year and currently sit on top of the table. In the referee ranks, ADTA Director of Referees, Ken Golden, has been putting the refs through their paces in favourable cool conditions in Williamtown.
