Embodied Carbon Emissions in Buildings

first_imgPhil and Chris, hosts of the Green Architects’ Lounge Podcast, define and discuss embodied carbon in buildings, and make an impassioned case for understanding why this is absolutely the most urgent issue we face in the design and construction industry today—even ahead of zero-energy building—as we work together to combat a fast-approaching climate crisis.Listen to the podcastAudio Playerhttps://cdn.simplecast.com/audio/244dd9/244dd98f-d8ab-4943-9b47-4fb0f1713e30/dfff632a-3e39-4bea-9f57-1c11892dfe95/gal_102_master2_tc.mp300:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume. Embodied carbon is carbon that is emitted in the production of materials, and the building industry is responsible for 40% of global annual emissions. Buildings are the problem and the solution, and understanding the immediate impacts of embodied carbon is absolutely vital.Phil and Chris define the critical difference between embodied and operational carbon, and explain why net-zero-energy buildings simply aren’t enough at this moment in time. They take a pass at understanding the numbers behind the issues. They also spend the second half of the podcast talking about the materials that we either must, or absolutely should not specify. Wood is good, steel and concrete are bad, but anyone in the industry knows that this doesn’t leave us with a simple puzzle to solve.The Cocktail: The Bennett Cocktail2 oz. Gin¾ oz. Fresh lime juice¾ oz. Simple syrup2 dashes Angostura bittersDirections: Shake all ingredients with ice to chill, then strain into a chilled glass. Garnish with a lime wheel.The HighlightsWhat is embodied carbon? Carbon that is emitted in the production of materials.40% of global annual carbon emissions are caused by building industry.We need to understand eCO2e (embodied carbon emissions) vs. oCO2e (operational carbon emissions).What are the differences between embodied (upfront) vs. operational carbon? (11% embodied + 28% operational = 39% total)?We don’t have time to mess around. New zero-energy-buildings are simply not good enough to save us in time. Energy is not a proxy for carbon.Buildings are the problem and the solution. It’s best not to build at all, but if you must—and we must—embodied carbon emissions become critical.How is our tribe doing already? For residential construction, we are doing pretty well, and it’s been a good testing ground. The nerds need to distill the data into actionable rules of thumb so the non-nerds can act.Commercial is the big nut to crack: 33% of embodied carbon is in the structure.We can’t get to net zero-carbon with a dirty grid.Transport of workers to the job site is the biggest source of emissions.Impact of the work we do is more important that personal changes we make.Sometimes it actually can be better to tear down and build a smaller, high performance building.Impacts of the construction process are 20-25% of the total.Understanding the numbersCalculations now are right enough, we need action more than precision.Use only very round numbers—1,2,5,10,20,50,100—so they are retained.EPDs are the MPGs for buildings.How can a number be negative? Regenerative building can actually fix the environment.Top five materialsFSC-certified wood (all wood is not the same)Natural building materials (straw/hemp/wool)Cellulose insulationCross-laminated timbersWood fiberboard insulationBottom five materialsAluminumConcreteSteelRefrigerantsSpray foamSong of the episode747 by Bill CallahanLinksCarbon Smart Materials PaletteCarbon CureCarbon Leadership ForumThe New Carbon Architecture by Bruce KingImages courtesy of Chris Magwood, Endeavour Centre; Jacob Racusin, New Frameworks; Ace McArleton, New Frameworks.The Green Architects’ Lounge hosts are Chris Briley and Philip Kaplan.

Five Industry Flame Wars No One Cares About Anymore

first_imgTags:#browser#Firefox#Linux#Microsoft#Microsoft Office#Netscape#OpenOffice#Windows Top Reasons to Go With Managed WordPress Hosting Related Posts There once was a time when Microsoft was evil, open source was the underdog and flamewars between the two camps were frequent and fierce. Those were the days! Today the industry has traded those early wars for equally vociferous fights between Android and iOS adherents, or HTML5 vs. native mobile application development. However, given how the early battles have faded, it’s likely that today’s nasty flame wars will be tomorrow’s distant memories.Don’t believe me? Let’s see if you still care about these epic brawls of the 2000s.Windows vs. LinuxAs religious wars go, few can top this blood feud. Coming at the height of Microsoft’s market dominance, Linux was the open-source upstart that promised to topple the evil empire, spreading peace, love and open source to all. Microsoft was not amused.Though the Redmond initially tried to discredit Linux as “un-American,” labeling it “a cancer” in 2001. When that didn’t work, in 2003 Microsoft launched its infamous “Get the Facts” campaign, which was long on propaganda and short on facts, then doubled down on the campaign in 2005. When this didn’t work, either, Microsoft got its lawyers involved, dropping an unsubstantiated bombshell that Linux infringed 235 of its Windows patents. The open sourcerors fought back, alleging that Windows infringed on Linux’s intellectual property. Throughout it all, CIOs bought both Windows and Linux servers en masse, while dumping expensive Unix servers. This ultimately seems to have cooled tempers, with Linux dominating in new markets like cloud computing even as Windows remains strong for more traditional enterprise workloads. A new pragmatism seems to govern server OS choice.As for the Linux desktop, it never really caught on, despite its adherents’ fondest hopes. But this also hasn’t mattered, as mobile has displaced the desktop as the premier consumer computing platform. There, Linux (à la Android) is dominant, not Windows, leaving the two camps with little to fight about except royalties.Internet Explorer vs. Netscape (Firefox)Microsoft was at the center of this religious war, too, first beating market-leading Netscape into oblivion with illegal antitrust behavior. The Netscape browser, however, resurrected as Firefox, and this time Firefox seriously cut into Microsoft’s market share, eventually claiming more than 20% of the global desktop browser market, according to Net Applications.Along the way, developers took sides, proclaiming their allegiance in the form of website badges suggesting which browser to use. As for Microsoft, it relaunched its Get the Facts campaign, this time challenging the open-source browsers in the area of security, privacy and more.Over time, this war subsided, despite once being waged in the judicial system and the comments sections of myriads of articles. The desktop became less important, initially establishing Apple as the dominant force in browsers with Google claiming significant share in both desktop and now mobile browser markets.Microsoft Office vs. OpenOfficeAre you noticing a theme here? Yet again, Microsoft is front and center, this time being with its cash-cow Office productivity suite business under siege by the open-source community. Well, sort of. For much of the 2000s, Sun sponsored the vast majority of OpenOffice.org (now OpenOffice) development, and then helped to drive the emergence of the Open Document Format (ODF). While OpenOffice never seriously threatened Microsoft, it did prompt a marketing response.But OpenOffice’s more important legacy, and the one that Microsoft fought more vigorously, was ODF. Across the planet, Microsoft lobbied hard to kill any attempt to institute an open format that would obviate its proprietary Office file formats. It largely succeeded, with adoption for ODF largely stymied.Even so, a larger threat to both ODF and Microsoft has been the emergence of mobile as a primary computing platform. While Microsoft continues to print profits from sales of Office, as the world moves beyond the desktop the need for a full-fledged office productivity suite is fading, whatever the file format. GPL vs. ApacheOf course, Microsoft isn’t the only entity to generate angst and ire in the 2000s. Within the open source camp, the 2000s saw bitter rivalries, including KDE vs. GNOME on the desktop (which neither side won) and free software vs. open source everywhere.The most visible proponent of free software and the GNU General Public License (GPL) that powered it is Richard Stallman. On the more permissive open source side stood Eric Raymond. For a time Stallman and the free source crowd had the upper hand, but over the past few years Apache-style licensing has won out, given the freedom and flexibility it affords developers. This trend accelerated as open source went mainstream, and developers became more concerned with getting work done than scoring political points.Open vs. ClosedThe backdrop for each of these industry flame-fests is the question of open vs. closed technology. Originally confined to a question of licensing, “open” has come to comprise much more, including APIs and data. New breed technology-heavy companies like Facebook espouse openness, arguing that it encourages developer adoption and improves their services. Meanwhile, the closed camp…doesn’t really exist.Oh, sure, there are some who argue that open source is not more secure, or that open data is dangerous, or whatever. But whereas “open vs. closed” was really the fundamental question of the 2000s, it has largely been settled. Today, “openness” is like motherhood and apple pie: everyone loves it, or claims to do so. Today Microsoft openly uses and often advocates open source software. Oracle owns the leading open source relational database, MySQL, and commits significant development resources to advancing it.Which is, perhaps, why today’s big debates are less dominated by quasi-religious overtones. Progress? Yes. But a bit boring?Sadly, yes.Image courtesy of Shutterstock. 8 Best WordPress Hosting Solutions on the Marketcenter_img Why Tech Companies Need Simpler Terms of Servic… Matt Asay A Web Developer’s New Best Friend is the AI Wai…last_img read more

Gujarat producing athletes to Nation

Till a year ago, these talented girls of Kalyani Girls High School in Ahmedabad’s Maninagar area, coming from poor economic background, lived on an uneven diet which meant low HB (hemoglobin) levels and malnutrition.HEALTHIER:Students of Kalyani SchoolToday, not only are they eating healthy, but are proving their potential in sports, with some even winning laurels at the state level. Hansa Thakore, 17, an athlete and a 5,000-m champion of the Gujarat School Games in 2006, works as a maid with her mother to eke out a living.Madhavi Barot lives with her handicapped father, has already lost her mother and yet won two state level gold medals in 3,000-m race. The father of Jashmika Soni, 16, state champion in 400-m race, is a rickshaw puller and lives in a one-room house with his five-member family. “Their transformation has purely to do with the new fortified diet that they have been getting”, says coach Yogesh Modi, The state Government floated a scheme in 2005 of fortifying edible oil and flour with vitamins at production or packaging stage to tackle malnutrition.A total of 620 women in Ahmedabad’s Daskroi taluka were put on a fortified flour diet for three months last year after which their HB levels went up. Vanitaben Parmar’s is a representative case. Wife of a factory laborer, earning Rs 2,000 a month, her HB count has risen from 7 to almost 11. “I feel much more energetic”, she concedes as do many of her ilk.advertisementA survey conducted by Sanguine Management Consultants recently in several districts of Gujarat at the behest of the State Food and Civil Supplies Department (SFCSD), shows that nearly 80 per cent of the people, both rich and poor, are now consuming fortified edible oils and over 40 per cent are living on fortified flour. Says a jubilant S.K. Nanda, department secretary, who was instrumental in the implementation of the scheme, “there are some small hiccups, but soon we will be able to cover the entire population of Gujarat under the scheme. In edible oil, we are close to achieving it.”After charting this scheme, SFCSD began working with edible oil manufacturers, packagers and refinery owners and convinced them to add Vitamin-A to the oil at the production stage. Vitamin packs are supplied by four companies and the whole process costs just five paise per kilo.Mill preparing fortified flourIt was, however, not so easy in the case of iron and folic acid being mixed with flour. The cost for this, too, is five paise per kilo, but small chakki (grinding mill) owners are resisting it as they see it as an extra burden. Apart from this resistance, there is also a problem establishing a time-bound and elaborate supply chain of iron and folic acid packs to mill owners in the far-flung and remote corners of the state.The scheme, however, is a boon for the below-poverty-line (BPL) families for whom malnutrition is a part of their existence. The Government is as a rule, selling only fortified oil and flour from its fair price shops, making BPL families the fastest beneficiaries of the scheme. If only the Gujarat model could be replicated in the rest of the country, a major front will be opened against the demon of malnutrition.last_img read more

Banking metal stocks keep indices under pressure Hindalco major loser

first_imgDomestic equity indices continued to trade sideways with marginal losses as banking, oil and gas and metal stocks continued to face selling pressure in the afternoon trade. Lack of any visible trigger resulted in a tepid performance of equities.While the 30-share index Sensex was trading 0.12 percent lower at 26,486.26 (1.27 pm), the 50-share index Nifty was at 8,141.05, down 0.16 percent on Friday trade. Among indices, shares of bank, FMCG, healthcare, metals and oil and gas were trading in the red, dragging the market in the afternoon trade. However, auto and IT stocks provided some support to the market indices.Meantime, market breadth was negative with 1,074 advances and 1,297 declines. Hindalco was the major loser with its shares down 3.72 percent in the morning trade at Rs 169.55. Bharti Airtel, ONGC, Tata Power and UltraTech Cement were the other major losers on Friday trade.Among gainers, Tata Motors was the major winner with its shares gaining 2.09 percent to trade at Rs 472.90. Zee Entertainment, HDFC, Bharti Infratel and Infosys also saw buying from investors.In the global front, performance of Asian indices remained mixed as major Asian currencies saw depreciation after US Fed hiked interest rates. Post US Federal Reserve’s hike of interest rate by 25 basis points, Chinese yuan touched its lowest point against dollar since May 2008. Weakness in Japanese yen also pushed Nikkei higher on Friday. US Federal Reserve hiked interest rate by 25 basis points to 0.75 percent from 0.5 percent earlier on Wednesday with an outlook of three rate hikes next year. US stocks rose on Thursday led by banking shares, supplementing the uptrend.Meanwhile, Indian currency was trading 0.10 percent lower at 67.76 against dollar on Friday. Among commodities, oil companies in West Asian nations informed customers about supply cuts in the near future, which pushed West Texas Intermediate (WTI) crude to touch $51.08 per barrel in US market.last_img read more

Immigration PN wants a serious plan and concrete action

He said that the PN, with its commitment and credibility, can bring results from the European Parliament.Timmermans proposal: Peter Agius and David Casa reactionNationalist Party MEP candidates Peter Agius and David Casa both reacted to the comments given by the Socialist candidate for the Presidency of the European Commission Frans Timmermans.Frans Timmermans spoke about the need that all European Union member states have one tax rate of 18%, in order to ensure equal conditions between all countries.From his end, candidate Peter Agius argued that it is clear that the harmonisation of tax rate to 18% removes all competitive advantages which Malta has in the industry of the present services, where it also attracts other industries which are based on the same model. He said that on the 25th of May, the Maltese cannot approve this socialist project.Candidate David Casa said that not only did the Labour Party not succeed in getting tax harmonisation out of the electoral manifesto, but “their buddy Timmermans” is now calling for a minimum tax rate “which will have a huge negative impact on Malta.”PN will continue protecting freedom of speech – Franciz Zammit DimechMEP candidate Francis Zammit Dimech said that the assassination of investigative journalist Daphne Caruana Galizia is an “attack on our freedom of speech and on our right to be informed about matters which affect us.” He also highlighted that the Nationalist Party was always at the forefront of this fight.Zammit Dimech also said that he is proud of the work he performed at the European Parliament in order to improve the legislation relating to work conditions so that work-related training is not paid for by the Maltese employee, in order for youths to have more opportunities thanks to Erasmus and to travel and study abroad for free, to safeguard employment within the pharmaceutical sector and in order to ensure that the tax advantages which Malta enjoys are not lost.WhatsApplast_img read more
