Adding Insulation to a 1944 Roof

first_img GREEN PRODUCT GUIDE RELATED ARTICLES Consider ‘storage capacity’ of the insulationWhile Albert Rooks believes that adding rigid foam is the easiest approach, he offers another thought about the differences between types of insulation that may play a role in lowering summer heat gain.“While lowering the indoor temperature peak on a hot day will obviously lower the indoor temps, increasing the cycle time that it takes to reach the interior peak temp means that the room can stay at comfortable temperatures longer,” Rooks writes. “That is the effect of the insulating materials heat storage capacity.”By choosing insulation with higher storage capacity, he adds, it will take longer for heat to work its way through the roof. The increase in indoor temperatures will still take place, but increasing the cycle time means lower overall heat gain and seeing peak temperatures at 3 a.m. instead of 4 p.m.Dense-pack cellulose and wood fiber insulation boards may have lower R-values per inch, Rooks says, but they have a much higher heat storage capacity than lightweight materials such as rigid foam. Green Basics: Insulating Roofs, Walls and FloorsGreen Basics: Rigid Foam Insulation7 Steps to an Energy-Efficient House: 2. The Roof” Q&A: Heat reflective roofing materialsGreen Basics: Roofing Material Choices RoofingHis plan is to tear off the existing roof down to the 2×4 rafters and then rebuild. The question is how.“Given the extremely limited depth of the rafter bays, I could get a few more R’s using spray foam or rigid foam, but I’m not sure that it would be worth the added expense,” he says. “One roofer has suggested adding pre-fab channels, edge vents and a ridge vent in order to ventilate the roof, but this just cuts the space available for insulation even more.”Cox’s roof project is the subject of this week’s Q&A Spotlight. Thaddeus Cox’s 1944 Cape Cod in Portland, Oregon, has a roof that needs some attention. Not only is the roof under-insulated, but it’s currently covered in two or three layers of asphalt shingles installed over the original layer of cedar. Roof sheathing consists of 1-in. thick boards.The International Energy Conservation Code recommends R-38 for the roof in this Climate Zone 4 house, far more than the R-11 batts Cox thinks are currently in place.But reducing winter heating bills isn’t Cox’s first concern, as he explains in this Q&A post at GreenBuildingAdvisor.“They are already pretty low with our ancient oil furnace, and should be lower after our gas conversion,” Cox writes. “What I’m most interested in is reducing the summer temps in the attic bedroom, presumably by reducing the heat transfer from the sun-heated roof.” RELATED MULTIMEDIA Video: Lstiburek’s Rules for Venting Roofs Beef up the insulationIncreasing the R-value of the roof is an obvious place to start, if only to reduce summer heat gain in the second-floor bedroom. He has more than one option.Even if Cox uses high-density foam, at roughly R-6.5 per inch, the 2×4 rafters will allow only enough insulation to reach R-26 at the most, so some additional depth would be required to reach code minimums. Low-density foam would need an even deeper rafter bay. With that in mind, Jon Schmid suggests furring out existing rafters to create a deeper rafter bay, then adding spray foam insulation.GBA senior editor Martin Holladay would go another route: “Install as much rigid foam on top of the existing sheathing as you can afford,” Holladay writes. “I would suggest at least R-30 of new foam – with or without channels above the foam.”Bob Coleman likes Holladay’s approach. Adding rigid foam on top of the sheathing is “far more economical” than adding spray foam or dense-packed cellulose inside the roof cavity, he says.If Cox wants to vent the new roof, he can build in a space between the rigid foam and new roof deck. Then there’s the roofing itselfHowever Cox chooses to increase the insulation in the roof, he’ll still need to finish the assembly with roof cladding, and this, too, will have something to do with controlling summer heat gain.In his original post, Cox says he was leaning in favor of Energy Star shingles to reduce heat gain, although he wasn’t sure if they were worth the extra expense. Roofing products that carry the Energy Star label have certain solar reflective qualities, and they must have warranties equal to or better than comparable non-reflective products.“Go for an Energy Star metal roof that will help deflect the heat (some lighter colors will almost absorb nothing),” writes Coleman, “then the foam helps seal in the cool generated inside, then a peel-and-stick or other [heavy] duty roof deck covering along with air sealing any gaps prevents conditioned air leakage.”Because they absorb so much heat, dark asphalt shingles are not the best choice in this project, Coleman writes: “If you put a blacktop driveway on your roof, the heat is going to come.”Although Cox isn’t inclined to go with metal, “due to cost, appearance and noise (think rain on a metal roof),” Rooks agrees with Coleman’s suggestion, adding that a metal roof will last much longer than shingles. Our expert’s opinionWe asked GBA technical director Peter Yost for his opinion. Here’s what he says:If the main objective of the new roof assembly is to improve overall thermal performance, but particularly to control summer heat gain, then it is always best to keep the heat out FIRST. Keeping solar heat out, before it becomes a conduction issue, is always the most effective summer heat gain strategy. Reduce the solar gain with a reflective roof cladding and if possible, introduce a ventilated air space underneath the cladding, which will increase convective heat exchange and provide a low-e surface on the backside of the cladding.I don’t think the specific heat capacity per volume of one insulation to another makes a significant difference. The specific heat capacity (per volume) of all insulations is relatively low and there is simply not enough storage in any insulation to match the day-night cycle of heat gain and loss in the roof assembly.One important way to take advantage of the day-night temperature cycle would be with night-time cooling: install an efficient whole-house exhaust fan to move hot air out and cool air in.I do like Martin’s suggestion of adding as much top-side rigid insulation as possible/economically feasible. Better bang for the buck and per inch of additional roof assembly profile. Something like this GBA detail for an exterior roof insulation retrofit.last_img read more

Shekhawati farmers withdraw agitation on loan waiver issue

first_imgThe farmers in the Shekhawati region of Rajasthan, largely comprising Sikar, Jhunjhunu and Churu districts, withdrew their 13-day-long agitation early on Thursday after the BJP government agreed to waive crop loans up to ₹ 50,000 and appointed a committee to study the procedure adopted in other States for its replication here.After the marathon talks with a group of Ministers till late on Wednesday night, CPI(M)-affiliated All India Kisan Sabha (AIKS) announced withdrawal of agitation and appealed to farmers to lift the blockades put up at scores of places on the highways. The sit-in being staged in several towns of the region will also be finished and roads vacated.AIKS president and Amra Ram, who led an 11-member farmers’ delegation in the negotiations, said the State government had agreed to most of the demands regarding procurement of crops at minimum support price and removal of restrictions on the sale of cattle. He appealed to farmers to clear the blockades and allow movement of vehicles.In addition to the crop loan waiver of ₹ 49,500 crore, the farmers were also demanding implementation of the Swaminathan Commission’s report, free electricity for agriculture and increasing farmers’ pension from ₹ 500 to ₹ 5,000 per month.last_img read more

Kalmadi says Delhi govt, Centre used 95% of CWG funds

first_imgIn a last-ditch attempt to defend himself in the Delhi Commonwealth Games scam controversy, an angry Suresh Kalmadi on Thursday pointed fingers at the government.He accused the investigating agencies of “targeting” only the Organising Committee when government officials were also part of the entire decision-making process.Reiterating his demand for a joint parliamentary committee(JPC) probe, Kalmadi said both the central and Delhi government are equally to be blamed for the scam.Speaking to the media in Ranchi, where the national games are on, he said the OC was being unfairly targeted.  Amid reports about the Central Bureau of Investigation closing in on him after the arrest of his aides, Kalmadi said no government official had been questioned by the CBI so far despite the fact that it was the sports ministry which had cleared all the contracts. Kalmadi insisted no decision was taken by the OC unilaterally. Dragging the Centre, Kalmadi said that the sports ministry was directly involved in the decision-making process at every step. Taking on the Delhi government, Kalmadi said the state government and the Centre had utilized 95% of the funds.He expressed shock and displeasure over the way the entire matter has been handled by the investigating agencies when all the documents pertaining to the conduct of the Games were with them.Asked whether he anticipated arrest any time, Kalmadi ended a press conference abruptly saying “Let’s see”.last_img read more

It pays to be personal

first_imgInside Influence Report, one of my favorite newsletters from the great gang at ASU, reminds us once again why it pays to be personal. Here’s the story, from Noah Goldstein:I have a friend who is a medical doctor. Nicest guy in the world. Will do, and has done, anything for anybody. So I was totally perplexed — and as a social psychologist, very interested — when I learned he was having difficulty finding someone to cover his shift on the weekend of my wedding. I asked him if he had ever volunteered to take his colleagues’ shifts, and he replied that indeed he had. Considering all he had done in the past to help them, and all that we know about the power of the norm of reciprocation, it was puzzling that he could not get a single person to volunteer to help him out during his time of need. By the time he had answered my next question, however, the solution to the mystery was clear. When I inquired how he went about asking for help, he said that he had sent out an e-mail. And it wasn’t just any of type of e-mail — it was a mass e-mail, in which all of the recipients could see all the other recipients. The problem with this strategy is that it creates what is called diffusion of responsibility. By sending out the mass e-mail in a way that made visible the large number of coworkers being asked, no one single individual felt personally responsible for helping. Instead, each recipient likely assumed that someone else on that list would agree to help. In a classic demonstration of diffusion of responsibility, social psychologists John Darley and Bibb Latané staged a situation in which a student seemed to be having an epileptic seizure during a study. When a single bystander was present, that person helped approximately 85% of the time. But when five bystanders were present — all of whom were located in separate rooms, so no one could be certain if the victim was receiving help — only 31% of the bystanders helped. Fortunately for this friend, Noah Goldstein knew what to do. He told the doctor to send personal emails asking individual people specifically. It worked. The doctor attended the wedding.The more your “asks” appear to be made from you, personally and directly, to an individual, the more likely people will support you. So segment your audience. Show you know them. Speak to them like individuals. Try some one-on-one contact with your biggest supporters. Mass, impersonal, Dear Friend emails just won’t do the same job. Just ask the doctor.last_img read more

Seven Words That Will Make Your Website Worth Viewing

first_imgSource: http://www.mrpwebmedia.com/ PsychologyThe most important feature you can offer your audience is psychological fulfillment, not deep discounts, fast service, or more bells and whistles.The real reason people buy stuff is that it makes them feel something. Cosmetics make women feel attractive or sexy, while cars make men feel they’ve achieved some level of status. Even services make people feel important, as in “I’ve got a guy who does that for me.”Finding the psychological hotspot in your marketing, and promoting the hell out of it consistently and continually, should be your primary marketing goal. All those features and benefits are merely the excuse for a purchase, not the reason. The Web Is Fast Becoming a Video EnvironmentWeb sites are not just marketing collateral; they are not just digital brochures. They are a new presentation medium that requires specialized communication skills, and knowledge of how best to use the medium.You may be a great salesperson and nobody knows your business like you do… and you may even be skilled at delivering speeches at conventions and seminars… but performing effectively in front of a camera is a whole different ball game. And for most people it’s way out of their comfort zone, let alone their skill level.The same old methods that used to work won’t work any more. You’re no longer competing with just the company down the street; you’re competing with the entire world.Web-based businesses may never actually meet their customers face to face or even talk to them on the phone, so it is imperative that they use marketing presentation methods that deliver an experience worth remembering. Words Can Move YouBy someone’s count there are 171,476 entries in the Oxford English Dictionary, plus another 47,156 words that have fallen out of favor, but not counting the 9,500 additional permutations that don’t deserve their own special attention.Half of these words are nouns, one-fourth are adjectives, and 14.285% are verbs; the rest consist of all those other things the purpose of which most of us long ago forgot.Others may find fault with these numbers, but no matter what the total, it’s a lot of words.Of the tens of thousands of words to choose from, most people recognize less than ten percent, while teenagers seem to only be able to handle about half that amount; of course, that doesn’t count slang, instant-messaging jargon, or the ever-popular four-letter variety.Why the heck are there so many words if we all refuse to use them? I mean, why waste all those perfectly good words on English teachers and college professors? (By the way, they say swearing is the refuge of the feeble-minded, people who can’t express themselves in a more articulate manner-but, to be honest, I really don’t give a damn.)Here’s the thing: Words have meaning and impact, and they provide the emotional context of our communications; and we add subtlety and nuance by how we deliver them, using tone, cadence, and gesture.That is, as important as words are… the way they are delivered is even more important. What Web Site Design Is Really AboutThe other day I was listening to a local all-news radio station. It is mostly rip-and-read wire-service stuff that they repeat over and over like some kind of psychological torture, but they do provide traffic reports on a nauseatingly regular basis. You have to wait only 10 minutes until they repeat everything. So if you want to hear what traffic snafus to avoid, just wait a few minutes. But here’s the problem: The announcers talk so fast that no matter how hard you concentrate, you can never quite get the particular information you need; and if you’re driving, you have other things to consider, like the idiot in the Hummer who just cut you off.None of these guys ever uses a period, let alone a semicolon or comma. Either they have very small bladders and are under pressure to finish quickly, or they’re late for their afternoon pilates class. They seem so intent on rushing to the commercials that they never deliver the content in an appropriate manner.Your Web site just might have the same problem.Too much information is as bad as not enough. Information overkill leads to information anxiety, buyer’s remorse, reduced satisfaction, unattainable expectations, and purchase-decision paralysis.Web site owners have been told that visitors won’t wait for anything, that they are impatient, and you’ve got to get to the point fast, make the pitch, and close the deal. Well, that approach just isn’t going to work with any sophisticated product or service.Your Web site presentation needs to slow people down so they hear what you have to say, and you have to say something worth hearing.Web site design is about more than layout, markup language, and technical wizardry. Web site design is about communication; it’s about turning advertising into content, and content into an experience that viewers will remember. Seven. A number like any other. But it does seem to come up on a fairly regular basis: the Seven Wonders of the World, the Seven Deadly Sins, and the Seven Dwarfs: Happy, Sneezy, Sleepy, Bashful, Doc, Dopey, and (my favorite) Grumpy.Phone numbers have seven digits. And may say the optimum brand name should be no more than seven letters long. Seven, it seems, is a magical number, because the human brain can grasp only seven things at a time (on average).So I’ve been thinking, What are the seven most important words associated with Web-marketing? I’ll give you a hint: Search, engine, and optimization don’t make the cut.So what words do make the list? What are the seven words that will make your Web site worth viewing? Seven Words to RememberCommunicationPeople are always asking us what’s wrong with their Web sites, and the answer in the vast majority of cases can be summed-up in a quote from the movie Cool Hand Luke (1967): “What we have here is a failure to communicate.” Communication is the key to success, and that doesn’t just apply to your Web site-it applies to almost everything you do both inside and outside your business life.If your Web site isn’t communicating on both a rational and an emotional level, if it doesn’t provide the psychological and emotional context of your marketing message, then exactly what is it doing?AudienceI can’t think of too many people who actually like being sold to. In fact, sometimes customers get so irritated by sales tactics that they end up not buying the thing they came specifically to your Web site to buy.Solving the problem is merely a question of altering your perspective. The average buyer is predisposed to dismiss and ignore high-pressure tactics and meaningless sales pitches. So instead of treating customers like customers, try treating them like an audience. Audiences want to be engaged, enlightened, and entertained. And that is the most effective way to make a sales impact. FocusAll too often, Web sites inundate their Web audiences with facts, figures, statistics, and an endless list of features, benefits, options, and whatever else the sales department can think of throwing in. But all that stuff just confuses people.Focus your message on the most important elements of what you have to say. If your Web site can embed that single idea in an audience’s mind, then it has done its job.LanguageThe words used, and how they are put together, provide meaning; they inform personality; they provide mental sound bites; and they turn whatever you are saying into something worth remembering.Language is one of the critical elements of “voice,” the ability to convey personality. Writing that doesn’t have “voice” is instantly forgettable.PerformanceEven the most articulate prose can be lost in befuddled delivery. Communication is more than words; it’s a combination of language, style, personality, and performance.Things are rarely what they seem. Even our memories are a stylized versions of what we’ve actually experienced. Creating a memorable impression is about managing the viewer experience and providing the right verbal and non-verbal cues that make what is being said memorable.PersonalityEvery business has a personality. The first problem is that few midsize companies ever attempt to manage that persona, and as a consequence the buying public forms its own opinion. And that opinion is often not the way you want to be regarded.The second problem is that companies either don’t have a firm grasp of who they really are or, if they know, they are afraid to promote it. If your company’s identity isn’t worth promoting, it is time to think why that is… and change it.The bottom line is that a company without a personality is a company without an image, and that makes you instantly forgettable.last_img read more

Nonprofit Home Page Tips

first_imgSource: Gayle C. Thorsen, Best Practices Nonprofit Web Site Design ebook Can you communicate in a few seconds what you do and why it’s important?Your nonprofit home page is a crucial introduction to your organization. Within a few seconds, a first-time user should understand the purpose and usefulness of your site. Your home page should show how your nonprofit website can meet the user’s needs; highlight your richest, most current content; and demonstrate your positive impact on society.Your home page (and all other pages) should load very quickly. Don’t use an introductory “splash” page or flash animation.Your mission statement and the word “welcome” should not be on your home page.Strive for simplicity and clarity in design. Your home page should be attractive and engaging, but uncluttered.Put your logo at the top of the home page and on every page on your site. It should always be linked to your home page.A one-sentence tagline on your home page should explain what you do and how you differ from others doing the same.An About Us link should be clearly available for users who want to know more about you.There should be a compelling, local photograph (not a stock shot) that echoes your tagline on your home page. The photo should have alt text and a message-rich caption.Contents are hierarchically arranged to match an F eye-movement pattern. Jakob Nielsen shows how readers tend to scan Web sites by moving left to right across the top of the page, then left to right slightly below the top of the page, then vertically top to bottom on the left side of the page-in a pattern resembling an F. Think about that pattern when placing your most important content.Links on your home page should quickly show readers what actions they can take on the site. Make it easy for them to find the answers to their questions.Share examples of your most interesting, recent site content. There should be a place to glimpse your latest news.There should be a place where people can sign up for your email newsletter. It’s critical to also include a large, colorful donate button.Make strategic use of keywords to make your home page more attractive to search engines.Let users know about your social media presences without distracting them with too many badges and widgets.If you offer an intranet, make sign-in easy to find and easy to use (no more than one click).Offer a site search option with a search box that’s 27 characters wide on every page.Put essential contact information on every page.last_img read more
