(At Least) Six Things Are Wrong With This Crawl Space

first_imgIssue 5: No polyethylene covering the dirt floorThe crawl space has a bare dirt floor. The crawl space air is in communication with the interior of the home. Because there is no vapor barrier on the dirt floor, ground moisture evaporates into the crawl space air, raising the interior relative humidity.Required Corrections: To limit the entry of ground moisture and soil gas, the dirt floor should be covered with a polyethylene vapor barrier, with seams lapped and sealed. The edges of the polyethylene should be sealed to the foundation wall. If radon testing shows elevated radon levels, then a sub-slab depressurization system should be installed to exhaust soil gases to the exterior.Ideally, add a layer of horizontal rigid insulation to limit heat transfer to the ground. Protect the insulation with a concrete “rat slab.” Issue 1: Electrical cable isn’t securely stapledAt some point in the past, modern electrical cable was installed to serve a floor receptacle. The cable was not properly fastened to the structure, and drapes freely across a five-foot span. This is a code violation.Required Corrections: The cable should be rerouted and supported with staples meeting building code requirements. If necessary, replace the cable so that it can be correctly routed and supported. Last week, GBA published a photo of a crawl space in an old house under the headline, “What’s Wrong With This Picture?”The photo showed an unvented crawl space in a cold climate. The home was built in 1885. This crawl space is attached to an adjacent concrete-floored basement. The foundation walls are made of mortared limestone.Even in the small area captured in the photo, there are a number of problems that compromise energy efficiency, building durability, and life safety. Here are our answers to the question posed last week. Garrett Mosiman works as a Research Fellow for the Center for Sustainable Research at the University of Minnesota. He has a bachelor’s degree in architecture from Rice University and an M.S. in architecture, Sustainable Design Track, from the University of Minnesota. He is also a LEED Accredited Professional. Issue 4: No capillary break at the top of the foundation wallThere is untreated wood in contact with the masonry foundation, a common situation in houses of this age. There are no signs of a capillary break to prevent foundation moisture from wicking into the framing.Required Corrections: If the foundation drainage is good and the assembly is exposed to warm interior air for drying, the risk of wood rot is relatively low. However, insulating the rim-joist area on the interior can increase the risk of rot, since added insulation would lower the drying potential of the sill. If the homeowner plans to insulate this area on the interior, it’s worth considering the installation of a capillary break. If the area will be insulated on the exterior, a capillary break may not be necessary.First, verify that there is good site and soil drainage on the exterior side of the assembly. Lift the sill — a task that sounds more daunting than it is in practice — and install a capillary break (metal flashing or a rubber membrane). Then insulate on the interior using rigid foam or spray polyurethane foam.center_img Issue 3: Knob-and-tube wiringThere is some knob-and-tube wiring. Although the wire appears to be cut, it’s impossible to tell by looking at it whether the wire is still live.Required Corrections: The wire should be removed back to a code-approved junction box. Consider eliminating all knob-and-tube wiring in the house. Issue 6: The crawl space walls are uninsulatedThe foundation walls are uninsulated.Required Corrections: The crawl space walls can be insulated with rigid foam or closed-cell spray polyurethane foam. Because there is no capillary break at the top of the masonry wall, exterior insulation is preferable to interior insulation. Issue 2: Asbestos insulationA hydronic heat pipe is wrapped with asbestos insulation. The asbestos lacks encapsulation to prevent contact with asbestos fibers. If this insulation is abraded, asbestos fibers will be released into the air. If these fibers are inhaled, they can lodge deep in the lungs, eventually leading to lung disease.Required Corrections: Hire a certified asbestos abatement contractor to remove the asbestos or stabilize it in place.last_img read more

3D Printing: How to Jumpstart A Stalled Tech Revolution

first_imgTo appeal to mainstream consumers, companies should be promoting the heck out of MakerBot’s Thingiverse, 3D Systems’ Cubify.com and other 3D blueprint catalogs. People love to shop, and these sites are bursting with downloadable free and paid designs—including customizable jewelry, cups, keychains, smartphone cases, tablet stands, lemon juicers, Star Wars cufflinks and much more—that render faster than FedEx could possibly deliver. One More CaveatThere’s yet another potential roadblock to 3D printing, although its outlines are still unclear: Possible health concerns. A recent study out of the Illinois Institute of Technology (published in the journal Atmospheric Environment) found that commercially available 3D printers emit substantial volumes of potentially harmful nanoparticles.On one level, this finding isn’t a complete shock; 3D printers, after all, use industrial processes scaled down for home use. On another, though, this is clearly an issue the makers of 3D printers will have to address head-on—potentially with new designs incorporating safety features, should further studies confirm these potential health risks.These blueprint stores could be the key. They are to 3D printers what app stores are for mobile devices. They’re an alternative to online craft marketplaces like Etsy. And they could give a distinctly real-world spin on social sharing that trumps Likes and badges by giving people an easy way to create, transmit and share physical items, even over distance.This is the final piece of the puzzle. More affordable pricing, ease of use and hot marketing hype have laid the groundwork. Now, it’s up to the companies to capture the imagination of average Joe or Jane Customers. If they can do that, the consumer tech revolution the industry so badly wants may finally be poised to take off. For more information about 3D printing, check out The Shapeways Blog or Make Magazine’sUltimate Guide to 3D Printing, or for more ideas for practical use-cases, visit this recent article from The New York Times.  Image of Star Wars cufflinks, Cartoon Character Maker and Citrus Juicer: Courtesy of Thingiverse users belch,sethmoser and walter, respectivelyAll other product/software images: Courtesy of companies as mentioned. UPDATE August 1, 2013: Today another supporter joined the cause: The 3D Scan-to-Print Web App hopes to make 3D printing even easier for end users. Its mission, as listed on Kickstarter: To “create a printable 3D model of any object using only a depth camera and a web browser!” For more, click here.  Why You Love Online Quizzes 3D printing, now effectively six years old, should be a blockbuster hit. It’s science fantasy made real, a futuristic technology that would put devices akin to Star Trek replicators in people’s homes. Its pioneers believe that 3D printing—which uses a variety of techniques to build physical objects from digital designs and a variety of plastic liquids, sheets or powders—can do for manufacturing what 2D printers did for publishing. In short, they anticipate a desktop revolution that puts fabrication capabilities once reserved for big corporations directly in the hands of creators of all types (ordinary people, too). See also: How An Army Of Makerbot Replicators Will 3D-Print The Future [Video]Unfortunately, high costs, required technical skills and utter failure to convey its benefits have stalled the movement before it really got started. Now, though, several distinct trends seem likely to bust those barriers (though there are also caveats, of course; see below). Here’s how it could all unfold—like a grand master plan for making widespread adoption of 3D printing a reality.Step 1: Drop The Price 7 Types of Video that will Make a Massive Impac… The Remaining ChallengesThere’s one more area the industry needs to focus on, and it’s a simple, yet crucial one: Creating customer demand. That’s an easy sell for creative niches like inventors, modelers and other artists who want to see real-life renderings of their concepts. But not everyone wants to design their own objects.  Pirate3D has a different approach. It offers a browser-based tool that uses drag-and-drop editing of “Smart Objects.” Starting with a stock object, users can manipulate shapes and dimensions by clicking and pulling on the top, sides, etc. (For a demo, click here.) See also: How Hard Is It To Get And Use A 3D PrinterStep 3: Show It OffDespite the bad press over the possibility of 3D-printed guns, 3D printing’s overall profile in the media has been positive. MakerBot stopped by The Colbert Report in 2011 before hitting Fashion Week a year later to offer 3D-printed sunglasses for menswear designer Asher Levine’s new line. Doctors now save lives using 3D-printed surgical implants, and NASA’s investing $125,000 to research printed food fit for space travel. (Looks like chocolate has been nailed. Next up: Pizza!)  3D Systems’ minimalist Cube 3D costs $1,299. Even less is the $499 Solidoodle, which was the cheapest unit I’d heard of … that is, until I spotted Pirate3D’s Kickstarter campaign. That $347 Buccaneer printer is potentially a game-changer. The beautiful, compact machine (that’s it pictured at the very top of this post) broke its $100,000 funding goal in the first 10 minutes. And by the end, it nabbed a cool $1.4 million in pledges. Of course, you get what you pay for. The Replicator 2 outputs bigger, more refined objects (up to 410 cubic inches) than the Buccaneer, whose build volume maxes out at 114 cubic inches. But if the MakerBot is the professional laserjet, then the Pirate3D unit is the home inkjet— a petite hobby printer whose Applesque beauty makes it a deskworthy appliance. Step 2: Make It Easy To Use3D printers work in a similar fashion to their 2D cousins, just with different materials and techniques. Modern 2D printers expel ink, line by line, until a document or image appears. Likewise, 3D printers extrude PLA or ABS plastic material, layer by layer, until a physical object takes shape. Or they lay down polymer powders or liquids and fuse them into position, again layer by layer. In both 2D and 3D printing, something needs to act as the print job, to tell the machines what to output. For 3D printers, that’s a design or blueprint.  How to Write a Welcome Email to New Employees? History makes one thing clear: Price can make or break new products. Just ask the Chromecast or the Surface RT. MakerBot, which is now owned by commercial 3D printing firm Stratasys, charges far less for its Replicator than the tens of thousands that high-end professional printers fetch. But not everyone can afford $2,199 for a Replicator 2. Tags:#3d printing#Kickstarter#MakerBot#manufacturing Related Posts This is where things get sticky. Animators and architects may know computer assisted design, but the rest of us don’t. And most of us never will, so user-friendly solutions are paramount. There’s already some simple software that dumbs down professional design programs, but a few companies are going a step or three further.  MakerBot’s Digitizer, unveiled last March, works like a photocopier. Users place small objects in the machine, and it scans and automatically creates a digital blueprint. The company also jumped on Microsoft’s new native 3D printing support for Windows 8.1 recently. Its new drivers enable direct plug-and-play support with PCs, so people can use their favorite programs to create and print directly to Replicators.  As the hype spreads, so do access and availability. Staples shoppers can now check out the Cube 3D in person, see the unit, ask questions and possibly even catch in-store demos. Microsoft will carry the Replicator 2 in its retail locations and online as well, joining MakerBot’s own website and brick-and-mortar storefront in New York. And e-tail giant Amazon now carries the machines in a special section of its website. See also: It’s Cool That Staples Now Sells 3D Printers—But You Don’t Need OneOther retailers, like Britain’s Tesco, see another opportunity: 3D printing services akin to photo printing at the local drug store. This type of arrangement could be a magic bullet for the technology. It would give people a way to experience it without a large upfront investment. [Update August 2, 2013: 3D printing services have also come to UPS.]  adriana lee Growing Phone Scams: 5 Tips To Avoidlast_img read more

I’m disappointed with stars pull out of CWG: Saina

If competition is not there it does not feel good as people come to see good contests,” Saina said on the sidelines of a promotional event on Thursday.Ace shuttler Saina Nehwal. Photo: Bhaskar PaulA number of participating countries have criticised the living conditions of the rooms in the towers that have been installed for the athletes and Saina said she was pained to read and hear about these negative publicity.”I am sad and it feels bad to hear these on television.But I cannot comment about the Games village as I am yet to see it. Without seeing it’s not proper for me to comment,” Saina said.In what should bring cheers to the ears of the under-fire Games Organising Committee chief Suresh Kalmadi, Saina also gave a big thumbs up to the badminton venue.”I have played there and it’s a top class arena. The stadium is excellent,” she said.Talking about India’s chances at the Commonwealth Games, Saina said the hosts are well poised to win a medal in each of the six events in badminton in Delhi.advertisement”We have all trained very hard in Hyderabad for the Commonwealth Games and I’m confident we have a chance to win a medal in every event we participate in,” said the world No.3.Six gold medals and an equal number of silver and bronze are on offer in badminton which is to be held at the Siri Fort Complex along with squash.Saina said the challenge for India would come from Malaysia, Singapore and Scotland.”We can expect tough challenge from Malaysia, Singapore and Scotland,” said the Hisar-born shuttler who is the brightest medal hope in badminton for the country in the CWG as well as the November Asian Games in Guangzhou, China.Talking about her own chances, especially in the light of the comments from her predecessor Aparna Popat that the country expected nothing less than a gold from her, Saina promised she would do her best.”I cannot promise a medal though I will be aiming for the gold. But I will give it my best shot,” she said.Saina said she had put the World Championship, where she lost in the quarter finals despite being ranked second, well behind her and was looking forward to the Delhi Games followed by the Asiad.”I am happy I tried my best and am now looking forward to the Commonwealth Games and the Asian Games. I feel my fitness levels have increased by over 60 per cent since the world championship. But we have to wait and see how things pan out,” she said.Saina said it was totally wrong to compare the sports infrastructure that exists in India to that of China because only in the last couple of years that the country has started to do well at the top most level like the Olympics.last_img read more
