Fridays on the Fly: How the EPA is Threatening Clean Water Fisheries

Fridays on the Fly: How the EPA is Threatening Clean Water Fisheries

first_imgEarly on his tenure, Trump-appointed EPA head Scott Pruitt began advancing an anti-environmental agenda that would, among other things, withhold critical safeguards from the nation’s headwater streams and wetlands.Since then, he has targeted clean water by trying to dismantle an Obama-era statute known as the Clean Water Rule or the Waters of the United States Rule. This rule, which Pruitt’s EPA is seeking to rescind, ensures the protection of 60 percent of U.S. stream miles and 20 million acres of its wetlands.Not only would a move to rescind it have detrimental effects on the vitality of America’s commercial and recreational fisheries, but it could put the drinking water of as many as 1 in 3 Americans directly at risk.“Almost certainly, some water bodies will face increased pollution under a narrower federal Clean Water Rule,” Daniel Esty, professor of environmental law and policy at Yale Law School, told the Scientific American back in February when Donald Trump placed the law under review. “It would leave some critical water resources less protected.”Critics like Esty have argued that the Trump Administration’s reasoning for attempting to withdraw the Clean Water Rule is based on a fundamentally flawed economic analysis that hinges on outdated recession-era statistics and an assumption that protected headwaters and wetlands provide no economic benefit to the American economy. The latter conclusion is particularly hard to stomach when you consider that the outdoor recreation economy contributes some $887 billion in annual consumer spending.If you value the clean water in your favorite rivers, streams, lakes and wetlands, there is still time to make your voice heard. The EPA is required to accept public comment until August 28, 2017. You can comment using this handy form from the folks at Theodore Roosevelt Conservation Partnership. Don’t forget to leave a personalized message about the ways in which pollution would damage the fishing holes you love.last_img read more

First home buyers can pay a fifth for an apartment in Brisbane compared to Sydney buyers

First home buyers can pay a fifth for an apartment in Brisbane compared to Sydney buyers

first_imgA one-bedder in inner city Petrie Terrace is seeking offers of more than $199,000 — a lot cheaper than a similar property would set you back in Sydney. Picture: realestate.com.auI had dinner with an agent this week — a young woman in her twenties selling units in the Eastern Suburbs of Sydney.We were discussing the cost of one-bedrooms apartment which she had recently sold or was currently negotiating.The prices of these ranged from $1 million to $1.7 million!When I asked her what was the main demographic of buyers, she said it was singles or young couples her age — say what?!Oh and for the record, these units were roughly all less than 50sq m, without harbour or city views and some without car parking spaces.In a week when the budget announced measures to help first home buyers enter the market, I genuinely hope they’re not trying to push them into these areas.Most of the country is offering great value, but these inner city markets of Sydney and Melbourne are not the place for a first homebuyer to be dipping their toes.More from newsMould, age, not enough to stop 17 bidders fighting for this home5 hours agoBuyers ‘crazy’ not to take govt freebies, says 28-yr-old investor5 hours agoTo give you some comparison you could do a search of properties listed in Brisbane’s CBD and find one-bedroom units for less than $200,000 or even in New Farm in the $200,000s.I completely understand the population benefits of Sydney, but is Brisbane really only 20 per cent (or less) of their price?Fortunately, the budget does seems to have a plan to steer these first home buyers into the markets that are not overstimulated.There is a provision in the budget that extends the powers of APRA, which can dictate to the banks on some of the lending criteria for certain suburbs.This could likely mean the banks will be restricted on the amount of money they can lend in these bull markets.I believe this and the levies applied to foreign investors, if used in the spirit of the budget, could slow these super fast markets.last_img read more

And,They’re Off!

And,They’re Off!

first_imgBy John BurtonMonmouth Park opens May 12 for its 67th seasonOCEANPORT – Those celebrating the start of a new racing season at Monmouth Park acknowledge, it’s been a tough year already.“It’s been quite a challenge,” said Dennis Drazin, the lawyer representing the New Jersey Horsemen’s Association, which will be operating the track.Drazin of Red Bank took the opportunity at a press conference and celebration prior to this week’s opening day to offer a brief overview of the struggle to ensure that the track, now under private sector ownership, would continue to operate.“You don’t know how close we came to shutting down Monmouth Park,” Drazin said.Drazin represents the association, which has control of the track through its management company, Darby Development LLC.The New Jersey Sports and Exposition Authority, which operated the track since 1985, had been in negotiations for some time, looking to hammer out a deal with the horsemen’s association that would allow the track’s continued operation. Gov. Chris Christie has said the state should get out of the racetrack business as tracks continued to see attendance dwindle and revenue decline. There had been widespread speculation that the track would close if no deal were struck.Among some of the hurdles that had to be jumped was getting support from the various entities needed to operate the track so plans could move forward, Drazin said.The track has been undergoing some aesthetic renovations in preparations for the season.“We haven’t been able to do all the renovations we wanted to this year,” Drazin said.In the future, he said, there will be a miniature golf course and a boardwalk-like attraction. The association plans to reconsider building a water park attraction.The strategy is to make the racetrack more of a family destination.“All of this is vital for the future,” Drazin said.Among the immediate changes for the season will be to catering and food service. “I don’t want to be critical,” Drazin said. “But we needed a change.”BAM Management, LLC will be responsible for food service this year with executive chef Erik Weatherspool, who gained some notice by winning on The Food Channel show Chopped.“We’re changing a lot of things,” the chef said.Weatherspool worked for about a decade at Joe and Maggie’s Bistro, Long Branch, and owned and operated Bistro 44, in Toms River. “The food will speak for itself,” he said.One of the big questions involves whether other types of gambling will be allowed at racetracks, Drazin said. That won’t likely happen for “five years, at least.”The reason is the Christie administration is working to revitalize the Atlantic City gaming industry, he said.“The future may very well include gambling in the northern part of the state,” but for now, “We need to focus on the revenue stream we have,” Drazin said.“We have to focus on the competitive product we have here at Monmouth Park.”Joseph Irace, Oceanport Borough Council president, who was on hand for the conference and luncheon said, “I think it’s a big positive,” what is going on at the track.“I see more excitement than we’ve seen in the last few years,” Irace said.The track is important for Oceanport, as it contributes about 28 percent of the town’s tax base and is its largest employer. Horse breeding is an important part of the county’s heritage and economy, Irace said.As for the horses, Mike Sedlacek, a trainer and owner of six thoroughbreds from Florida, said he has been spending the last few years running his horses exclusively at Monmouth Park, and living in Howell for the season.“I like Monmouth and was a little nervous,” about its prospects, he said. “Where would I go now?”last_img read more

first_imgThe importance of reading and the impact literacy have on society were highlighted at the World Book Celebration in Johannesburg this week.Tebogo Ditshego, author and entrepreneur, with actor Thapelo Mokoena at the fifth World Book Celebration, held in Johannesburg on 30 May 2017. Mokoena says: “if we do not tell our stories, we will never be our own heroes”. (Images: Melissa Javan)Melissa JavanTebogo Ditshego, founder of the online book club ReadABookSA, said we needed make sure we prioritised the right things. “We say we can’t afford books but on weekends we make a plan to get drunk. How about we replace the beer bottle with a book? What would our future then look like?”Ditshego was one of the speakers at the fifth annual World Book Celebration, held in Auckland Park in Johannesburg on 30 May 2017. The event was hosted by public relations company Ditshego Media in collaboration with ReadABookSA and OR Tambo International Airport.It was also the celebration of the first anniversary of Ditshego’s self-published book, Kasi Nerd. Ditshego is also one of Brand South Africa’s Play Your Part ambassadors.Speakers included South African actors Masasa Mbangeni and Thapelo Mokoena, entrepreneur Lebo Gunguluza, author and playwright Siphiwo Mahala, and Emmanuel Bonoko, the founder of EBonoko Foundation.

Bonoko says that the true value of success includes having a legacy.A thirst for knowledgeDitshego, founder and chief executive of Ditshego Media, urged South Africans to not only take care of their children, but to make sure their children had a thirst for knowledge. We must make being intelligent look good, he said.“It’s not about having swag, but rather to have intellectual swag.”The volume of the thirst for knowledge should be turned up; we should turn up at book clubs instead of dance clubs.In addition, Ditshego spoke about land, saying people had a spiritual connection with their land; they needed to reconnect with the land. “Connect with yourself first — know your [African] history. If you don’t know where you come from, how will you know where you’re going?“In every one of us there is a story,” he said, and pointed out that he wrote Kasi Nerd in six weeks. Its messages included that education would set you free and that you could not have a free mind if you did not read.Audience members at the World Book Celebration each received a copy of Kasi Nerd, signed by the author.Glad to have my book sighed before leaving for home.

He had no interest in accounting, but lack of knowledge made him want to study the field.He found out about film and the arts industries when he was studying at the University of Witwatersrand in Braamfontein. “I discovered institutions where I started feeling what I wanted to do. Being surrounded by that energy is what I enjoyed about being in these spaces.“My interest in the art of storytelling grew and grew.” He dropped out of accounting and started classes at the film school, Afda.Without reading he could neither act nor create stories, Mokoena said, adding that he was busy reading about and researching for the role of a journalist. “For the past seven years now I’ve become a solid reader. So many truths are found from reading books.”Mokoena encouraged the audience to tell their stories. “Let’s take the pen, the camera and the scriptwriters back… Unless we tell our stories, we will never be our own heroes.”“Until we tell our own stories, we will never be the heroes in the stories we read.” @ThapeloMokoena #WorldBookCelebration #KasiNerd pic.twitter.com/yDZC5UXXcD— Tebogo Ditshego (@TebogoDitshego) May 30, 2017Implementation is keyBonoko said he had seen many people who had ideas, but who never took action. “The world is inspired by people who get things done,” he said. “Implementation is key… be more of a doer.”Many things that trended on Twitter did not add value to communities, he said, urging South African youth to spend time on issues that would have an impact on the country.His message was spread on Twitter:Let’s strive for ownership – Emmanuel Bonoko #KasiNerd— FezileNomzamo (@fezilenomzamo) May 30, 2017“Let’s rechannel our energies to things that matter.”- @EMMANUELBONOKO #WorldBookCelebration#KasiNerd— Sydney Madibo (@sydneymadibo) May 30, 2017Bonoko said we should collaborate to be successful as a nation. “Let’s support each other; let’s be there for each other.“I learned from my mentor: ‘never assume someone is less important based on where they are today, because you don’t know where they’ll be tomorrow.’”Attendees at the fifth annual World Book Celebration in Johannesburg on 30 May 2017:Xolani Mogale and Lucky Nkoma enjoy the event.Noxolo Ntsokolo, Sindiswa Mkhwanazi and Onneile Khwene talk about the World Book Celebration.Poet Tebatso Mokoena, a performer at the World Book Celebration.Would you like to use this article in your publication or on your website?

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

Kim was joined int the stands by several senior officials, including the country’s nominal head of state, Kim Yong Nam, who will lead a high-level delegation to the South Korea Olympics on Friday that will also include leader Kim’s sister, Kim Yo Jong.Kim Jong Un didn’t make any comments about the Olympics in the parts of his speech that were broadcast. The coverage of the parade seemed heavily edited.North Korea had said it would hold a big event to mark the 70th anniversary of the founding of its military. Feb. 8 has been seen as a less important founding anniversary but made something of a comeback in 2015 and was elevated further this year in part because it is the 70th — a nice round number.The parade also featured tanks, armored vehicles, jets flying over the square in formation to make a “70,” and thousands of people dressed in red, white and yellow creating the letters “Kim Jong Un” in Korean and the ruling Workers’ Party’s symbol of the brush, hammer and sickle. The North also rolled out what appeared to be a Hwasong-12 intermediate range missile, which it flew over Japan twice last year as it stepped up the aggressiveness of its weapons tests.In this image taken from video footage, North Korean military personnel salute as they lay flowers in front of giant statues of Kim Il Sung and Kim Jong Il on Mansu Hill in central Pyongyang, Thursday, Feb. 8, 2018.

Kim Jong Un has gone out of his way to make sure the North will hold attention throughout the games.Following a last-minute proposal during Kim’s annual New Year’s address, North Korea is sending 22 athletes to compete in the Olympics and a delegation of more than 400 musicians, singers, martial artists and members of a cheering group to the games.Kim is also dispatching his younger sister, Kim Yo Jong, to attend the opening ceremony. That in itself is a major development — she is one of his closest confidants, holds a senior party position and her trip would mark the first time any member of the ruling Kim family has visited the South since the Korean War. She will meet South Korean President Moon Jae-in at a luncheon, Moon’s spokesman said Thursday.The North’s conciliatory moves related to the Olympics have generally been welcomed in the South. The parade, however, was seen as more sensitive.Though possibly best known for their legions of goose-stepping troops, North Korean military parades are the country’s primary means of showing off its most recent advances in military technology — sometimes with aspirational mock-ups.The North unveiled five new kinds of missiles at its most recent major military parade last April.
