SIMPLY RED STAR HUCKNALL TAKES DONEGAL ESTATE BATTLE TO COURT

SIMPLY RED STAR HUCKNALL TAKES DONEGAL ESTATE BATTLE TO COURT

first_imgSIMPLY RED musicians Mick Hucknall and Christopher De Margary ongoing dispute with a neighbour over fishing and shooting rights on adjoining estates in County Donegal will be heard in court today.Lead singer Hucknall and sax player De Margary are due in Letterkenny Circuit Court in the dispute with their neighbour John Wilde.They claim he has interfered with their rights and those of their guests on the Glenmore Estate at Welchtown, Ballybofey. Mr Wilde retains links to a neighbouring estate across the river Finn at Cloghan Lodge, where he still lives, although he sold it some years ago.Hucknall and De Margary, who are keen anglers, are claiming that since they purchased the fishing, shooting and “hereditaments” rights for €1.3 million at Glenmore on August 5th, 2005, Mr Wilde had interfered with their “quiet enjoyment” of those rights.They said Mr Wilde had also laid claim to the ownership of the rights on Glenmore.Mr Wilde however claims the previous owner of Glenmore, John Mackie, transferred the fishing and shooting rights to his father.The musicians were refused an injunction preventing alleged continued encroachment at the same court four years ago.All eyes will be on Letterkenny court house today as two legal heavyweights begin setting out the case for their clients.Damian Crawford will represent Mr Wilde, while Peter Nolan will represent the world famous musicians.The chart-topping stars acquired some rights to the River Finn outside Ballybofey in 2006 after they bought the Glenmore Rivers estate.Both are keen anglers and saxophonist De Margey even set up home on the estate.Hucknall, 56, often stays on the 24,000 acre Co Donegal estate where he is popular with locals.SIMPLY RED STAR HUCKNALL TAKES DONEGAL ESTATE BATTLE TO COURT was last modified: March 24th, 2014 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:Christopher De MargarydonegalJohn WildeJUdge John O’HaganLetterkenny Circuit CourtMick HucknallSimply Redlast_img read more

Malaysia Airlines Business Class Review

Malaysia Airlines Business Class Review

first_imgWhen I first stepped foot on Malaysia airlines flight MH124 to Kuala Lumpur from Perth my heart sank, seeing an almost empty plane broke my heart as I’m a big advocate for Malaysia Airlines and the contributions they have made to the aviation world.  What has happened this year could have happened to any airline (and indeed has) but why Malaysia Airlines have had the two tragic incidents is a mystery that may forever go unsolved.  Thankfully, the flight home was completely full and after two days at Malaysia Airlines headquarters watching the steps this airline is taking to rebuild it was a great sight to see.  But enough of that, my main priority for being on the flight was to review Malaysia Airlines very popular Business Class and to sample their signature dish, the peanut satay.In flight entertainmentMalaysia Airlines doesn’t hand out the noise cancelling headsets until after takeoff and they collect them again 30 minutes before landing so when you’re offered a paper before takeoff I suggest you take it because a good hour of the flight will be spent with no in flight entertainment. The actual screen is large and clear however when the lights are on and the sun is out it was a little difficult to see on the window seat. There is an excellent choice of movies and TV shows available and being that Australia is one of Malaysia Airlines most important markets – our tastes were definitely catered for.Food and Beverage serviceBusiness Class passengers are offered the standard pre departure welcome drink upon boarding and not long after takeoff another drink is offered from the full beverage selection available as well as a hot towel. The menu featuring three main meal options had something for everyone but I noticed on the flight from KL that a lot of passengers had taken advantage of the Malaysia Airlines Chef On Call service. Business Class passenger can go online 24 hours before their flight and pre select their meal/s from some 20 selections rather than the three offered on board. Whilst I enjoyed the menu onboard the flight, upon having a look at the online menu for Chef On Call I would definitely recommend this service as the meals being served looked and smelt even better than that offered from the onboard menu. One thing I noticed about Malaysia Airline’s main courses versus other airlines was the serving size. They were amongst the most generous I had experienced and of a high quality too -no padding out with onion here. The actual service delivery was exemplary and I was impressed considering the short flight time. To have a full Business Class cabin served and cleared within 90 minutes on both flights demonstrates the efficiency and skill of the staff onboard. The cabin crew on both flights were nothing short of excellent. Prior to the meal, another hot towel is given and then the tables were lain with white linen cloths and meals served on china with stainless steel cutlery, china mugs for tea and linen napkins. The appetizer for the flight to KL was of course the signature satay sticks served with peanut sauce and they were every bit as good as I had anticipated. Soft meat, chunky peanut sauce and a little cucumber to add to the mix as well as the option to have seconds and thirds if you wished! The picture really sells this signature dish much better than any words ever could and next week I will share with you exactly what goes in to making these satay sticks – all 26000 of them a day!Seat and amenitiesThe Business Class seat on the A330 was quite hard and at best reclined to an angled flat bed of approximately 160 degrees which I just slipped down. There were plenty of other recline options available to get comfy but lying flat was not one of them. This seat however needs to be put into perspective – I was only on a short flight, long haul flights feature completely flat lie flat beds with a mattress and duvet. The blankets on the flight were my biggest disappointment – they were what would I would expect in economy and with no spares available on the flight home I froze (admittedly I feel the cold more than most). Pillows were of a decent size and eyeshades and earplugs are available upon request – there is no amenity kit offered as such on these flights however on the flights over 7 hours there is an amenity kit on every seat. In the Business Class bathroom, toothbrush and toothpaste packs were available as well as aftershave, shavers, moisturiser lotion and mouthwash.Final WordOverall my Business Class experience was excellent and with important fundamentals such as service and food ticking all the boxes there’s not a lot to complain about. I would love to see those blankets upgraded and gate to gate in flight entertainment offered but other than that it’s a competitively priced, high class business product and one that I would highly recommend.EmailTwitterlast_img read more

MH370: New search underway

MH370: New search underway

first_imgSearchers for missing Malaysia Airlines flight MH370 are having a final roll of the dice by moving north into a 25,000 sq. km search area defined by a meeting of high-powered experts as the potential crash site.The last remaining ship in the search, the Dutch-owned Fugro Equator, moved into the new search area on January 6th and is conducting sonar sweeps in a last-ditch attempt to locate the missing Boeing 777, which disappeared in March, 2014 with 239 passengers and crew on board.The move, less than two weeks before the search is scheduled to end, is an attempt to cover at least some of the area now believed to likely contain the debris field.The search is being led by the Australian Transport Safety Bureau which confirmed the change to AirlineRatings.com.  “Fugro Equator is completing its final swing and gathering some sonar data in areas we haven’t previously completed,” an ATSB spokesman said. “Equator’s search operations are expected to be completed by the end of January.” Dr Richard Cole, from the University College of London, has been tracking the ship and revealed the decision to head north into the new search area.“Equator has re-entered the search to the north, away from the area originally identified in late 2014 by the Australian Defence Science and Technology Group,’’ he told The Daily Beast. “Using a sonar system, it is now checking sea floor not previously scanned. The search has only limited time left, but they are investing this remaining time in scanning the area they now believe is the most likely location of MH370.”The Equator left Fremantle on Monday December 12 and a typical mission lasts 40 days which would mean that the ship has approximately two more weeks to search this new area.An $A200m sweep of the 120,000 sq km area defined in 2014 as a probable location for the debris proved fruitless but a meeting in November of global aviation and crash experts defined the additional area using new information from ocean drift research made possible by the discovery of debris on in the Western Indian Ocean from the missing plane.The new area is deeper and more rugged than the previous search area, with some sections 6000m deep, and experts say a thorough search would require two ships.All eyes are now on the Malaysian Government, which has responsibility for the investigation, to see whether it will fund the $A40-$A50 million it would take to complete the search of the new area. The Australian government has shown little enthusiasm for putting extra money into the search but would likely allow the Australian Transport Safety Bureau to continue heading the effort if Malaysia funds it.The three governments involved in the search — Malaysia, China and Australia — decided last July to end it once the sweep of the original 120,000 sq, km, search zone was complete if no new credible evidence of a specific location for the debris was forthcoming.The transport ministers of Malaysia and Australia indicated last year the 25,000 sq. km search area was not specific enough, despite a recommendation by the experts that it should be searched to exhaust the remaining possibilities of finding the plane. The finding that the search should continue is backed by the families of MH370 victims and members of the search team.Malaysia Transport Minister Liow Tiong Lai said last week the decision whether or not to extend the search would be taken before the end of January but indicated it was likely to end.“We are in the final lap. The search will be completed in the next two weeks, then after that we will let people know. We will have a tripartite meeting,” Malaysia’s The Star newspaper quoted Liow as saying.Platitudes are not enough for families needing answers on MH370: Read our comment on contiuing the search.Meanwhile, reports have emerged that a French background check of the plane’s passengers and crew found nothing suspicious. France is investigating the crash because four French nationals were on board and officials told family members of the victims that the backgound checks had “turned up negative”, AFP reported.last_img read more

Stability returns to South Africa

Stability returns to South Africa

first_img18 May 2015Stability has returned to South African and further loss of life following recent xenophobic violence has been prevented, says Jeff Radebe, the minister for performance, monitoring and evaluation in the Presidency.He was satisfied with the work of the inter-ministerial committee (IMC) on migration to stabilise the country. It has been just over a month violence broke out in parts of KwaZulu-Natal and Gauteng.“The work of the IMC in dealing with all the underlying causes of the tensions between communities and foreign nationals, and the prompt activation of the Natjoints [National Joint Operational and Intelligence Structure], as well as the deployment of the security forces to volatile areas, has served as a strong deterrent to potential perpetrators,” Radebe said yesterday.Speaking about the progress of the work done by the IMC, he said security agencies continued to work around the clock to protect foreign nationals and South African citizens against any attacks.“We are maintaining law and order around the country. We believe the attacks against foreign nationals have been stopped because of the work done by [the] government and civil society organisations in mobilising communities to denounce the violence, and ensure peace and harmony among all who reside in our country.”Arrests madeA total of 3 914 people were arrested for various crimes during an operation aimed at addressing security challenges across the country. “It needs to be noted that while 1 650 undocumented migrants were arrested, 2 264 South African citizens were arrested in connection with various crimes.”Those arrested were held for crimes such as human trafficking, possession of explosives, drug possession, murder, robbery, rape as well as the possession of illegal firearms, housebreaking, and theft as part of Operation Fiela-Reclaim, he said.Operation Fiela is a multidisciplinary operation by various state entities to stop crime. It deals with illegal weapons, drug dens, prostitution rings and other illegal activities.“As a country, we are concerned about the safety and well-being of all those who live and work here and we want to ensure that both South Africans and the foreign nationals who live in our midst, are and feel safe,” Radebe said.He reiterated that the operation was not targeting law-abiding citizens or law- abiding foreign nationals. “The government will never authorise actions that are contrary to our Constitution and the laws of the country.”Hijacked buildingsThe operations were intelligence driven and would continue to target areas, buildings and spaces which were known to be frequented by criminals. In the next weeks and months, the government would accelerate its efforts to take back public buildings that had been hijacked either by foreign nationals or South Africans.Efforts would also be made, he said, “to rid townships and villages of drugs” such as nyaope, wunga and tik. “We are determined to take back the communities from criminals and to re-assert the authority of the state.”The IMC would continue working to deal with the underlying socio-economic issues that prompted the tensions between South Africans and foreign nationals.“Issues of migration management have been the sole responsibility of the Department of Home Affairs. As we move forward, we will be including all of government in developing a new integrated migration policy to address our challenges in a collaborative and integrated manner,” Radebe said.Stakeholders such as civil society and foreign national organisations would participate in managing migration.The government welcomed the skills that foreign nationals brought and the contribution they made to the economy, the minister said. “We are, however, concerned about those, both South African and foreigners, who illegally run businesses that are in some cases unlicensed, as well as those who engage in collusion, evade taxes, import counterfeit goods and conduct illegal business practices to the detriment of our economy.”As part of Operation Fiela, the government would ensure that informal businesses were properly licensed and local government by-laws were effectively implemented.In addition, Radebe said 5 645 people had been repatriated voluntarily. “The Department of Social Development continues to work closely with other relevant departments, as well as civil society organisations, to provide support to displaced foreign nationals.”Source: SAnews.govlast_img read more

How Heat Moves Through Homes — Building Science Podcast

How Heat Moves Through Homes — Building Science Podcast

first_img GREEN PRODUCT GUIDE How to Retrofit Old Masonry BuildingsAir Barrier or Vapor Barrier? RELATED ARTICLES The Basics of Heat FlowAs construction methods and materials change, and energy gets more expensive, how and why we insulate our homes become more important. CONSTRUCTION DETAILS In our last episode, Dr. Joe Lstiburek talked about efflorescence and the serious damage that water and salt can do to masonry. This week, Dr. John Straube explains how the three forms of heat flow work, and debunks the claims of a few common insulating materials.Comfort is the Primary Purpose of BuildingsSo, I actually call this “thermal control, insulation, and thermal bridges,” because thermal bridges are important. Let’s go back again and say, “Why do I want to control the heat flow?” Well, there are a whole bunch of reasons, but we often forget that the No. 1 reason we want to insulate is for thermal comfort. So, we want to make sure that exterior walls, roofs and floor slabs — that the temperature of these components stays above 68° in the wintertime and below 78° in summertime.If the wall or roof or slab gets too far beyond those ranges, we feel discomfort regardless of what the thermostat says. Actually, a lot of interesting buildings that work well that don’t have a lot of insulation — say, the old five-wythes of masonry built in 1864 or something like that — they work not because they’re that well insulated if you put them into our value test; they work because they maintain the surface temperatures at a relatively high level in the winter and are relatively cool in the summer. Even though the air temperature may not be that well controlled, you feel comfortable in them. And so just maintaining comfort is the No. 1 reason why, when we moved to lightweight assemblies, we had to start adding insulation; it was just too darn cold. MULTIMEDIA Blown-in InsulationSpray Foam InsulationRigid Board InsulationStructural Insulated Panels What is heat?Heat is energy in the form of vibrating particlesThe faster the particles move, the farther they move apart — slow particles make solids, faster ones turn to liquids, and even faster ones become gases Can Foam Insulation Be Too Thick?‘Insulating’ Paint Merchants Dupe Gullible HomeownersComfort Comes With Green BuildingBeware of R-Value CrooksUnderstanding R-ValueInsulation OverviewInsulation ChoicesInsulating Roofs, Walls, and Floors So, to understand a little of this, we’re going to go through the three modes of heat transfer: conduction, convection and radiation. Those three modes of energy transport are acting all the time and in parallel; they don’t really interact that much. We have to look at each of the three to understand the total picture.First, we should understand the nature of heat. Heat is vibratory energy in molecules. At any temperature that we’re experiencing, the molecules are vibrating. If you put more heat into them, they vibrate faster. In fact, if I take a piece of stainless steel and I put so much heat into it that I get to about 2,000 degrees, it’ll actually vibrate so much that the whole thing falls apart into a liquid. And if I keep heating that up, it’ll boil and the molecules will fly off into a vapor.So, whatever the heat is, it’s vibratory molecules, and when we talk about conduction, we have hot and cold as one solid object, and the fast-vibrating hot molecules physically collide with the slower-moving cold molecules and transfer momentum. By transferring some of the speed from the hot to the cold, the hot gets colder, and the cold gets warmer; that’s how heat is transferred by conduction.Conduction requires contact and low R-valuesTo have this mechanism work, you need solid material so that the molecules are directly in contact. Even having a gap of an eighth of an inch, you stop conduction. You still have conduction through the air, but the two solids have stopped. Our most common experience with this is metallic materials. You have a frying pan — cast iron — you put your hand on it. If it’s been sitting in the fire too long, the heat will conduct up to the handle and it’ll be hot. What we do to stop that, of course, is we put a piece of wood around the handle of the frying pan because the wood is less conductive.Now, the way we measure the performance of conduction is something we call conductivity. And conductivity is a material property, like vapor permeability is a material property. The symbol is typically K, but in Japan and Germany, they use the Greek symbol lambda. We can figure out what the resistance is. By figuring for a specific thickness, you get a conductance, and from the conductance, you do an inverse and you get R-value. That measures resistance only.Unfortunately, if this is the science behind it, the R-values that we see installed on our Styrofoam SM or on fiberglass insulation, they actually also include convection and radiation (we haven’t talked about that yet). So, the R-values we use for insulation products aren’t really scientifically based on conduction.If air or water move freely you get convectionConvection is the movement of the hot molecule here to over here by physically grabbing the whole bundle of molecules and dragging it across. So, it’s a mass flow movement of grabbing the hot fluids, which could be water from the boiler, and transporting it to the second-floor bedroom; or it could be a hot furnace, and transporting it to the kitchen — but just physically moving the fluid. That’s convection.Convection, actually, is more important in our building assemblies than most people realize — and it’s because our building assemblies have gaps and openings in them and we use materials that allow air to flow through them. And so when we look at something like a fiberglass batt that’s been installed from the inside, as I push this friction-fit batt, these fibers get pulled backward, right? They have to because of friction. Then that causes the fibers to stick out here, so the installer tucks the batt in like that. That’s your standard thing. As the installer tucks the corner in, it compresses the batt insulation and often causes a wrinkle at the middle.How do we know this? Well, we get people who install fiberglass batts with Plexiglas sheathing and we look at the far side and can see all these little gaps and openings form. So, this is what it really looks like.Batt insulation rarely works well in the real worldThe question is: What happens at these gaps? Well, this will be filled with hot air because it’s on the warm side; this will be filled with cold air because it’s on the cold side. Hot air rises and cold air falls, and so we have these two micro-ducts on either side of the fiberglass insulation. As hot air rises, it goes through the insulation and comes down and goes around like that. And that transports energy.How much energy? Well, it depends on how big those gaps are. Twenty, 30, 40 percent of the total heat flow across the wall can be by this mechanism. Which means your R-20 batt will drop to R-12 or R-10.What’s neat about this mechanism is that as the temperature difference across the wall increases, there’s a greater and greater proportion of heat flow transported by this mechanism. As you need the R-value more and more, it actually drops. Which is why when they test R-value in labs, they never test it like this because then they wouldn’t get R-19. So, what they do is they turn it on its side and they make darn sure there are absolutely no gaps — no studs, no gaps. They also make sure that the temperature difference across the batt is never more than about 30 degrees. That way, all this shit can’t happen and they can just get good R-value numbers.Now, if you take an R-19 batt and have the audacity to install it in a vertical application, your R-value goes down. If you then have little gaps — like batts are actually installed — well, then your R-value goes down. The bigger the temperature difference, the more the hit is; it’s a nonlinear relationship.But it gets worse. Not only do we have the gaps and openings around it, we have the studs in between that, and of course the heat flows more easily through the studs than it does through the batt. So, who cares about the R-19 of the batt when the heat’s actually flowing through the triple studs around the window? And the steel studs?With wood studs, you can argue that if you were a perfect tradesperson, you would install with no gaps at all. If you were given the three minutes per batt to install — most installers of course use at least three minutes to install a batt — you could probably make this work. But if you put it in a steel stud, the lips on the steel stud guarantee that no matter what level of trade quality is provided, you will have gaps around that steel stud. And those gaps will be the size of that lip — both 3/8 of an inch by an inch and a half wide. So, you’re guaranteed to lose between 30 and 40 percent of your R-value just right there. Isn’t that cool? Or hot, depending on the weather really.This same loopy stuff can go on in wintertime around insulation installed in attics, because there’s nothing stopping the air from looping around up here, and if there are any voids around the rafters or joists, you get loops going on. In some cases, when the temperature drops to 10 degrees, some types of blown-in fiberglass (which mostly aren’t sold anymore) at 20-degree outside temperatures were getting half the rated R-value, and at 0 degrees, which does happen on the coldest day of the year in northern Minnesota, they were getting something like 30% of the minimum rated R-value.So, you’d blow in R-40 and you’d get R-15 on the coldest day of the year, which of course is precisely when you need the most R-value. By the way, the way they fixed that these days is you go in and blow 4 to 8 inches of cellulose over top to provide a kind of air-impermeable cap on top of the fiberglass. So, if you do have problems, it’s often quite convenient and inexpensive just to blow a foot of cellulose on top and you’ll get a major improvement in performance.Radiation likes empty spaceThen we have radiation. These vibrating molecules create waves in space-time, which we call electromagnetic radiation. At the temperatures that we’re talking about, they’re infrared radiation.If you were to make these molecules move fast enough, they would eventually glow red-hot; you’d be able to see them. They’d go from infrared to actual red. And if you keep heating them up, they’d get white hot. And if you kept heating them up, they would actually start giving off ultraviolet radiation — and then a nuclear explosion, you’d get gamma radiation, they’re so hot.But most of our building applications aren’t worried about that. We’re worried about infrared radiation. That’s what infrared cameras look for: They look for the emission of radiation given off by the temperatures that the molecules have. Now, for radiation to be important, it really likes to transfer through — not solids; it likes to go through voids. It doesn’t even like to have gases in the way. That’s why the sun is able to transfer its energy from 93 million miles away to the planet Earth; because basically there’s nothing between us and the sun other than vacuum, except for the last 30 miles or so. Not even — it’s really only about 5 miles of air between us and the sun. So, radiation is quite effective. About 90% of the radiation given off by the sun hits the planet’s surface. We’re trying to change that, of course.Now, what you need is a gap. If you have aluminum foil, which does not emit radiation very well, it does not change the heat flow across the building assembly unless there’s an air gap. So, you need a gap.The Thermos bottles — they’re shiny glass on the inside, and that’s so there’s an air gap, and the shininess deals with the radiation. If you filled that void up with foam, the R-value would go down, not up, because you would eliminate any radiation benefit of the shiny metal. So, you have to have the gap; a slightly bigger gap would be good.Now, within the pores of insulation like fiberglass or rockwool, there are so many voids that radiation actually does play a role in jumping from fiber to fiber inside that product. And in a fiberglass batt, about 40% of the heat transfer at common temperatures is due to radiation. Foam, it’s about 30%. Now, the reason that matters is that as the temperature changes, the contribution of radiation changes.We’ve all probably been around a fire on a cold night; watch the campfire burn and you can feel the heat radiating to your face. That’s because it’s hot. It really makes a difference whether that fire is hot or cold whether you feel the radiation on your face or not. As you get down to building-related temperatures — 100 degrees, 50 degrees — radiation gets less and less important.But at high temperatures, radiation is important and it’s a major transfer mechanism; at low temperatures, it doesn’t play as big a role. So, radiant barriers are very good for high temperatures — say, the roof in a sunny climate. They’re less important for cold conditions — say, the underside of a crawlspace; they don’t play as big a role. But in every case they need an air gap.NASA’s radiant barriers are useless when you pour concrete over themWith radiant floor heat, it is actually kind of misnamed. There is radiation transfer, but actually most of it is by convection. So, convection matters, radiation matters, but more importantly, when I think of radiant floor heat [I think of] snake-oil salesmen who sell these radiant barriers underneath radiant slabs. Radiant-radiant, right? They should go together; they’re both named radiant.But of course, when you pour concrete on the aluminum foil, there’s no air gap, is there? So, there’s no R-value benefit. The R-value of a piece of aluminum foil underneath a chunk of concrete on top of soil is around 0 — somewhere between 0 and bupkus. However, they don’t test them that way, do they? They test them in horizontal apparatuses with an air gap above and an air gap below with ridiculous temperature differences across them. And then they get, like, R-8. But it’s hard to suspend that slab 4 inches above the radiant foil in most of my radiant slab designs.So, what they’ve done to address that is they put the little bubble wraps — the radiant foil bubble wraps, and so on — and they have, well, tiny bubbles (Don Ho sang about that until his recent death). These tiny bubbles in between the aluminum foil do help the R-value, and you can get as much as R-1 on some of the bigger bubble products.Now, the cost of that R-1 bubble wrap per R is about 3 times the cost of buying extruded polystyrene foam, but you can market this stuff as “space age.” Well, NASA uses it. OK, let’s think about this. I’m in outer space. There is no air. So, what are the heat transfer mechanisms? Well, there’s no convection; there’s no air. All I’ve got is conduction and radiation — so, if I’m not touching it, of course there’s only radiation. NASA uses radiant barriers because radiation is the only way they can transfer heat from them to other spatial bodies. It’s the only mechanism that works. ‘But as long as you’re building your buildings on Earth, in an air-filled environment, there are other mechanisms that are actually more important. But the NASA technology and the “ceramic balls” — it’s all just bullshit.But somehow they manage to sell this stuff by playing on people’s ignorance. They’re not sure about how all this works. Why insulate?For thermal comfortTo save energyTo stop condensation and the potential for mold and rotTo reduce the size, cost, and complexity of our HVAC systemsIn order to slow the flow of heat through our foundations, walls, windows, and roofs, it helps to understand what heat is and how it moves. Roof/Wall ConnectionsWall/Floor ConnectionsFoundation/Floor ConnectionsWindow Details How can it move?Conduction: solid things touching other solid things — drywall touching wall studs touching plywoodConvection: fluids, like water or air, moving around in an open space, like a pipe, wall cavity, or roomRadiation: heat in the form of electromagnetic energy moves through open space — the less stuff in the way, the better Windows are tough to keep warmNow, we still have that problem in our windows and our doors. So sliding patio doors — large areas of R-2 — well, they’re not very comfortable either in hot weather or in cold weather to sit next to. They just don’t meet the test of providing sufficient thermal control for comfort. We’re not even talking energy. So, they fail the first test.We also want to control surface and interstitial condensation. Now that we are quite clear on “condensation occurs on cold surfaces,” we can also now look at the psychometric chart and say, “So, how cold is cold?” Well, it depends on interior relative humidity, right? And if we keep the relative humidity in, say, the 30% range in cold weather, that means the surface temperatures have to be above 35 or 40 degrees. If you’re in the 40% relative humidity range, you now have to keep interior surface temperatures above 45 or so degrees.And again, where do we get that surface condensation? On our windows, because our windows are the least insulated part of the building enclosure. So, we see that first. But we also can get it in corners and at thermal bridges.R-5 meets most comfort and condensation concernsThe next thing is to save energy. But really, our struggle first and foremost in terms of stopping the biggest problems is: Make sure we get comfort; make sure we don’t get surface condensation. That’s what we need to have minimum levels of insulation for. And actually, R-5 will solve those two problems by and large in most climates. R-10, and you’re a slam dunk — even though we see codes with R-40s and R-20s and whatever. If we could just get R-5 everywhere, we could solve 95% of comfort and condensation problems — and R-10, we’d solve 99% of them.But we can’t do that because we can’t even achieve R-5 and R-10. Saving energy, reducing operating costs and pollution is what the building codes are worrying about when they specify R-values — and we’ll find out how useless that is as an approach to saving energy as we work through this presentation.Energy-efficient buildings need smaller heatersThen we have to save distribution and heating plant costs. Most people seem to forget that if I actually do a good job of controlling heat flow across my building enclosure, it means I can reduce the size of my air conditioner, the size of my furnace, the size of the ducts, the size of diffusers, the size of the fans, the size of the fan motors, the size of the filter, the size of the space it requires to put all of that into a building.So, we see a lot of life-cycle cost analysis of insulation and air tightness and such, and almost never do they include the escalating cost of energy — and they never include the rather significant savings that can be achieved in terms of downsizing your air conditioning plant, or your furnace or your ductwork. When you start reducing the size of ductwork or even eliminating it almost entirely, well, that opens up architectural opportunities: “Oh, you mean I don’t have to put in a suspended ceiling here? You mean I don’t actually have to take the duct to the outside wall?” Well, of course you don’t. If you insulate your walls sufficiently and provide good windows, you don’t have to provide a duct to the outside wall; you can provide the heat at the inside wall and simply blow the air over there. If you have a piece of junk wall and a piece of junk window, yeah, not only do you have to put the vent right below the window, you’re still going to be uncomfortable. But the duct savings are significant; it’s just that they’re not usually reaped.Meeting codes doesn’t guarantee good performanceNow, decreasing load diversity is something that matters to commercial buildings; less so to residential. Load diversity is the term used to describe the fact that at one part of the building you may have a significant cooling or heating load, while at the other part of the building you have the opposite. It’s very common in commercial buildings, for example, to have the east side require cooling at 10 o’clock in the morning. The sun is shining through the east windows, everyone has moved into the office, it’s all heated up; whereas on the west side, they’re still running the boiler to keep it hot.The only way that situation could actually occur is if you have a very bad building enclosure. And yet it’s pretty common; it’s a pretty common scenario. And that’s not just energy wasting; that’s annoying for the controls people have to work out. It’s annoying that you have to have systems that can do cooling and heating at the same time — what a pain in the butt. And yet by building bad building enclosures, we have managed to create that as almost a standard in office buildings and schools, etc., in our part of the world.And of course there’s the “I don’t wanna go to jail reason” to meet codes and specifications — which I always put at the bottom of the list. But actually, most designers that we work with, they put that as No. 1: “I don’t care if it matters; we’re just going to meet the codes.” And building code officials who say, “Look, just put R-20 in there. I don’t care if it actually does anything; jut put it in there to meet the code.”Heat and how it moveslast_img read more

Sambhaji Brigade to stage a demonstration outside PMC

Sambhaji Brigade to stage a demonstration outside PMC

first_imgPune: The Sambhaji Brigade, a pro-Maratha outfit, has demanded the Pune Municipal Corporation (PMC) to immediately install a statue of Maratha warrior King Sambhaji (son of Shivaji) in place of a bust of eminent Marathi playwright Ram Ganesh Gadkari in Sambhaji Park.Santosh Shinde, a member of the Brigade, said the outfit would stage “a massive demonstration” outside the PMC building on May 4, in view of the civic administration’s “tardy response” to the outfit’s demands, and “more than 5,000 activists” are expected to join the outfit in the demonstration.“We submitted a detailed list of our demands and grievances to the new Pune mayor, Mukta Tilak, a fortnight ago. She assured us that she would discuss the matter with leaders from all political parties in the House and take a decision. However, no concrete action has been taken,” said Mr. Shinde, speaking to The Hindu.In January this year, R.G. Gadkari’s bust, a fixture in the Sambhaji Park since its installation in 1962, was vandalised by four activists of the Brigade, on grounds that the early 20th century playwright had allegedly ‘defamed’ King Sambhaji by portraying him as a compulsive alcoholic and a womaniser in his unfinished play Raj Sanyas. The activists had thrown Gadkari’s bust in the Mula river after uprooting it from the park.The bust was later retrieved from the river, but the PMC has refrained from re-installing it owing to pressure on the Brigade’s part.The outfit defended their act by claiming that a bust of the playwright “should have no place in a park named after Sambhaji.”The controversial act has since led to a bout of statue politics with members of the Brahman Mahasangh, backed by a city-based BJP legislator, installing a photo frame of Gadkari in place of his uprooted bust. Both, the Brigade, and political parties like the Bharatiya Janata Party (BJP) and the Shiv Sena, have traded barbs on the matter, with each accusing the other of dividing society along caste lines by pitting the Maratha and the Brahmin sections against each other.Mr. Shinde said the outfit has urged the PMC to take up the issue with Chief Minister Devendra Fadnavis in a bid to bring the matter to a speedy resolution. “We will also be submitting a resolution to Pune Guardian Minister and BJP leader Girish Bapat on the issue,” he said.May 14 will witness the 360th birth anniversary of Sambhaji. “The purpose of our demonstration on May 4 is to ensure that the PMC and the State government takes serious notice of our long-pending demand. We have no objection if Gadkari’s bust is re-installed in the neighbouring Bal Gandharva or shifted to any other place,” Mr. Shinde said.last_img read more
