UPDATED on April 16, 2015More and more designers of high-performance homes are buzzing about a superinsulation standard developed in Germany, the Passivhaus standard. The standard has been promoted for almost two decades by the Passivhaus Institut, a private research and consulting center in Darmstadt, Germany.The institute was founded in 1996 by a German physicist, Dr. Wolfgang Feist. Feist drew his inspiration from groundbreaking superinsulated houses built in Canada and the U.S., including the Lo-Cal house developed by researchers at the University of Illinois in 1976, the Saskatchewan Conservation House completed in 1977, and the Gene Leger house built in 1977 in Pepperell, Massachusetts. Aiming to refine North American design principles for use in Europe, Feist built his first Passivhaus prototype in 1990-1991.Feist later obtained funding for a major Passivhaus research project called CEPHEUS (Cost-Efficient Passive Houses as European Standards). Conducted from 1997 to 2002, the CEPHEUS project sent researchers to gather data on 221 superinsulated housing units at 14 locations in five countries (Austria, France, Germany, Sweden, and Switzerland).The Passivhaus standard is a residential construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. To meet the standard, a house needs:The standard recommends, but does not require, a maximum design heating load of 10 watts per square meter and windows with a maximum U-factor of 0.14.The Passivhaus airtightness standard of 0.6 AC/H @ 50 Pa is particularly strict. It makes the Canadian R-2000 standard (1.5 AC/H @ 50 Pa) look lax by comparison.Unlike most U.S. standards for energy-efficient homes, the Passivhaus standard governs not just heating and cooling energy, but overall building energy use, including baseload electricity use and energy used for domestic hot water.Most European Passivhaus buildings have wall and roof R-values ranging from 38 to 60. Wood-framed buildings usually have 16-inch-thick double-stud walls… center_img Start Free Trial Already a member? Log inlast_img read more

Geek Movies: The Top 10 Most Inspirational Films For Techies

first_img5. Weird ScienceTwo high school boys “feed” their computer with as much real-world data as they could obtain during the Reagan era. The result: their idea of the perfect woman. Tags:#film#geek 2. Star WarsYou already know. There’s nothing more to add.   4 Keys to a Kid-Safe App What is a geek, anyway? Someone who loves math and science and computers? Sure, but that’s only part of it. As counter-terrorism expert Richard Clark once told Stephen Colbert (around the 3:40 mark): “Geeks get it done.” That nails it. Geeks Get It Done – GGID. Geeks imagine, then build. Geeks envision, then destroy. Geeks remake the old world and create new worlds. Sometimes just for fun, sometimes because the fate of all humanity hangs in the balance.That’s why geeks get inspired by movies that remind them to revel in their obsessiveness – because it ultimately leads to the way you “get it done.” Which movies do the best job of providing that awesome inspiration? You can’t go wrong with these 10 classics: 1. The MatrixYou are your code.The Matrix is so good that the hot, leather-clad love interest who snaps necks and knows how to handle a semi-automatic doesn’t even make it into the top 5 best things about this movie.  9. Galaxy QuestThe obsessive Star Trek-fanboy parody done right. When it comes on television, you can’t not watch it. Why? Because it inspires you to never stop believing. 8. Star TrekThis Star Trek reboot took us back to the future – to the early days of James T. Kirk, Spock, and the Enterprise. Think of just how awesome it will be if the new Star Wars films are as successful as this Star Trek reboot. “I dare you to do better.” 3. Iron ManWealthy industrialist, playboy, inventor, badass. It’s like if Bill Gates were as cool as he is rich.  Related Posts 5 Outdoor Activities for Beating Office Burnoutcenter_img 4.

I Know All These Things. I Just Don’t Do Them.

This eBook will help you Seize Your Sales Destiny, with or without a manager. Download Now The very first publisher that contacted me about writing a book asked me for a manuscript, and I delivered a completed manuscript. The title was 17 Elements: The Periodic Table of Sales Success. The book was really a competency model, including the mindset and skill sets one needs to succeed in sales now. Naturally, the metaphor was a periodic table, which I believed worked well because we are still identifying new elements, and we will no doubt add to the competencies needed to succeed in sales.The publisher read the book, and he hated it. He asked me, “Why would you start a book with self-discipline? What does that have to do with sales? Everyone hates discipline.” I knew that he had never worked in sales, so when I asked him if he had, my question was rhetorical, but he answered me in the negative. I did my best to explain, but it was clear we weren’t going to write a book together.Today, a salesperson described my work using the title of this blog post. He said, “When I read you, I think ‘I know all this stuff. I just don’t do it.” And here we find the root cause of many—if not most—challenges when it comes to producing results in any endeavor, but especially one like sales, one that requires consistent activity.Right now, while the world suffers a new version of neomania, one driven primarily by technology, things that are ancient don’t garner much attention. Much of what success is made of hasn’t changed for thousands of years, things like discipline, trust, caring, listening, resourcefulness, initiative, and accountability. While a lot of people try to hack their way to success, they’d be better off looking backward in time for the recipe than looking into the future for the quick hack. What you need to know to be successful has been known for generations. There are no secrets, and it has all been written down.Everything you need to know is known. You likely know everything you need to know now, and what you don’t know you can find in seconds. If you are not getting the results you want, it is because you aren’t doing what you know you need to do.Everything you need to know is known.

Naroda Gamm massacre: Deadline set for Maya Kodnani’s defence

first_imgThe special trial court, conducting the trial in the Naroda Gamm massacre case during the 2002 riots, has asked former Gujarat minister and key accused Maya Kodnani to get BJP President Amit Shah to testify in her favour as defence witness by next Tuesday.While asking the accused to ensure that the witness testifies by September 12, the court said there will be no further adjournment of the case.In her application on Friday, Ms. Kodnani said since Mr. Shah is not “reachable” due to his busy schedule and constant mobility, “It is difficult to decide as to which address the summons be served to him.”Ms. Kodnani, who was convicted in the 2002 Naroda Patiya massacre case, in which 97 persons belonging to the minority community were killed, is a key accused in the Naroda Gaam massacre case, involving the brutal murder of 11 persons, also during the 2002 riots.Also read: 28 years for Maya Kodnani, Bajrangi to spend entire life in prisonShe had sought time till September 12, 2017 while Special judge P.B. Desai had granted time till September 8 for her to bring Mr. Shah to testify as defence witness.During the hearing, Ms. Kodnani urged the court to allow her to bring Mr Shah and 13 others as her witnesses to testify that she was not present at the site when the massacre was carried out.Among the 14 persons she listed as witnesses, 12 including her husband have already testified in her favour. Mr Shah is the last listed defence witness in her trial; all others have been cross-examined by the court.Verdict deferredIn a separate case, the Gujarat High Court has again deferred its verdict on Zakia Jafri’s challenge to an SIT court granting a clean chit to Prime Minister Narendra Modi and others in a criminal conspiracy related to the 2002 riots.last_img read more
