Zite Gets New CEO, Updates to Cooperate With Publishers

first_imgTags:#mobile#news#Social Bookmarking#web Social aggregation magazine Zite (our review) released an update to its application this morning that is a direct response to the Cease & Desist letters it received from news publishers after launching the application in late March.The company also announced that it has a new CEO as Mark Johnson replaced founder Ali Davar as chief executive. Davar will step into the role of president “where he’ll lead the publisher relations team to explore innovations in publisher monetization,” according to a post on Zite’s blog.Publishers had been unhappy with Zite after its debut because it stripped ads out of its aggregated content. The update to the application now shows articles from certain publications in “Web” format as opposed to its stripped down “reading format” hence preserving the ads.See Also:UX Evolutions: News On iPadIn a post on his personal blog, new CEO Johnson says that his goals are to improve the quality of Zite’s recommendations, improve the sleek user interface and work with publishers on monetization strategies.“I liken where Zite is to the early days of search: everyone loved search engines because they allowed us to sift through the rapidly growing web, even though most searches ended up in failure,” Johnson wrote. “Similarly, Zite’s personalization isn’t perfect, but we’ve made a breakthrough advance.”Johnson has been an advisor to Zite (before it pivoted from “discovery engine” Worio) for two years before becoming the CEO today. He has worked with Microsoft on Bing and other search related startups such as Kosmix, SideStep and Powerset. From a technology perspective, Johnson is a good fit to be the CEO of Zite because the app uses its Worio search background as the basis for the iPad Magazine. Zite crawls content sources much the same way that a search engine would and returns results to the application interface. Zite also uses social media feeds to bring in content and has a recommendation engine similar to “music genome project” created by streaming music service Pandora.

Expanded Cork — The Greenest Insulation Material?

first_imgCost and availabilityNorth American distribution channels are just being set up, so pricing is far from certain. (One U.S. distributor of cork insulation is Small Planet Workshop.) But Simoes told me the price to a distributor will be about $0.70 per board-foot, not including shipping, markups, or the exchange rate. If those mark-ups come to 50%, the cost per board foot would be $1.05 and the cost to achieve R-19 would come to about $5.50 per square foot for cork, vs. $1.10 – $1.60 for polyisocyanurate insulation and $2.00 – $2.25 for extruded polystyrene.That’s a significant upcharge for cork, but you end up with one of the greenest building materials anywhere. I’m so excited about expanded cork insulation, in fact, that I’m hoping to use it on an upcoming building project later this year.You can read my full review of Amorim Isolamentos’ expanded cork insulation board at (membership required). You can also visit the company’s website or send an e-mail: [email protected] Cork insulation performanceExpanded cork insulates to R-3.6 per inch. It has a density of 7.0–7.5 pounds per cubic foot and compressive strength of 15 psi (with 10% compression). It is intermediate in its permeability to moisture — with a 40 mm layer having a permeance of 2.2 perms. Although the expanded cork insulation gives off a smoky smell, a test report I examined showed the material to pass France’s stringent requirements for a dozen volatile organic compounds (VOCs) with flying colors. Cork also has superb sound-control properties.From a fire-resistance standpoint, it meets the European Class E designation (the standard met by other rigid insulation materials) without the need for flame retardants that are used in the most common boardstock insulation products. A 40 mm-thick piece of the boardstock insulation held over a torch will resist burn-through for an 60-90 minutes, compared to less than 10 seconds for expanded or extruded polystyrene, which meets the same Class E designation. (The flawed manner in which we determine fire-resistance properties of materials is the topic for another article.)Cork insulation has been used as a rigid insulation material for decades in Europe. It is not uncommon to install an 8- to 10-inch layer on exterior walls and a 10- to 12-inch layer on roofs. The first Passive House built in Austria (in 1995) used a 350-mm layer (nearly 14 inches) of the material. It is typically used as an exterior insulation layer, much like polyisocyanurate. In Portugal, the world’s leading producer of cork, these oak trees are federally protected, and many cork forests are certified to Forest Stewardship Council (FSC) standards. Harvesting is done by hand, much as it has for over 2,000 years. While cork oak forests in Portugal are expanding, cork’s market share for bottle stoppers is dropping as plastic stoppers and screw-off caps become more common — motivating the company to look for new markets. I’m always on the hunt for the latest, most interesting, and most environmentally friendly building materials, and I have particular interest in insulation products — partly because many conventional insulation products have significant environmental downsides. (See “Avoiding the Global Warming Impact of Insulation” and “Polystyrene: Does it Belong in a Green Building?”)So I was thrilled to learn about expanded cork boardstock insulation made by the Portuguese company Amorim Isolamentos and just now being introduced into the North American market. Francisco Simoes, of Amorim, visited our office in Brattleboro in June and told us all about it.Familiar to wine drinkers as the traditional bottle-stopper, cork is a natural product made from the outer bark of a species of oak tree that grows in the western Mediterranean region of Europe and North Africa. The bark is harvested after trees reach an age of 18-25 years and it regenerates, allowing harvesting every nine years over the tree’s 200-year life. RELATED ARTICLES Cork Insulation on Our FarmhouseInstalling Cork InsulationBuildingGreen Announces Top-10 Green-Building Productscenter_img Cork as a building materialI have long been a fan of cork flooring, floor underlayment, and acoustical wall coverings. These materials are made from residual cork that remains after punching cork bottle stoppers from the bark — which consumes only 25% to 30% of the bark.For cork flooring and these other products, the cork granules are glued together with a binder and then sliced into the finished products.Expanded cork insulation is quite different. The same cork granules are used, but they are exposed to superheated steam in large metal forms. This heating expands the cork granules and activates a natural binder in the cork — suberin — that binds the particles together. In an in-depth product review about expanded cork insulation in the August issue of Environmental Building News I describe the fascinating history of this process. (It was invented by accident in New York City in the late 1800s).After producing these large billets of expanded cork, they are sliced into insulation boards in a wide range of thicknesses — in both metric and inch-pound (I-P) sizes. In I-P units, thicknesses from a half-inch to 12 inches are available — with dimensions of 1′ x 3′ or 2′ x 3′.The material is 100% natural and rapidly renewable as defined by the LEED Rating System. It is durable yet ultimately biodegradable, produced from sustainable forestry operations, and a byproduct from the cork bottle-stopper industry. Though there is significant shipping energy required to bring it here, shipping by ocean-going vessel is relatively energy-efficient. It’s hard to imagine a greener building material.
