NREL’s 3D Design Software Is Thoroughly Field Tested – and Perpetually in Line for Improvement

first_imgIt used to be that the Department of Energy’s principal software tool for energy efficiency modeling in buildings was EnergyPlus, a text-based simulation program for modeling heating, cooling, lighting, ventilating, water, and other types of energy flow in buildings. Then, in April 2008, the DOE’s National Renewable Energy Laboratory released OpenStudio, a free tool that combines the features of EnergyPlus with those of Google SketchUp, the search giant’s drawing interface.That blend of programs allows architects and builders to sketch 3D drawings of buildings and run energy efficiency simulations for each visual configuration very early in the design process, when implementing changes typically is the least expensive and early insights into building performance are critical.“Integrating energy analysis into that phase is very important because you can start to reduce energy use well before a building is even in conceptual design,” Nick Long, a NREL engineer who helps develop OpenStudio, said in a recent press release. “Our hope is that by using OpenStudio in design charrettes, users can start throwing away designs at the very beginning of a project, saying: ‘This is not a good design because we’re going to use too much energy,’”A software developer’s playgroundWhile there is a fair amount of software – some of it requiring the use of special monitoring hardware – being developed to help evaluate the performance of completed buildings (especially homes), tools that help address energy efficiency and building-geometry issues simultaneously, in the conceptual phase of design, can greatly increase the odds a structure will be functionally and aesthetically in top form by the time construction is completed.Better still, OpenStudio, which was developed using open-source (rather than proprietary) software code, is a perennial candidate for improvements, the NREL notes. Among the enhancements currently being considered: integrating OpenStudio with a daylighting program; linking it to a construction-cost database; and connecting it to the U.S. Green Building Council’s Leadership in Energy and Environmental Design.last_img read more

BuildingGreen Announces Top 10 Green Building Products

first_imgAddressing resilience and energy efficiency“After a year of record droughts and floods across the country, this year’s Top-10 products include several for managing moisture in buildings or for irrigating more responsibly,” says BuildingGreen founder Alex Wilson. “In selecting this year’s products, we looked for companies addressing resilience, energy efficiency, thoughtful use of materials, cutting-edge system optimization, and other needs.”This year’s selections include software for modeling heat and moisture flows, concrete masonry units with sequestration of carbon dioxide, a low-e coating for windows that opens new possibilities to energy-efficient, passive solar windows, and an LED streetlight meant to deliver 100 lumens per watt to precisely the area where the light is needed. Proponents of green building have spent years fighting the impression that sustainable design is all about product selection. It’s difficult to swim upstream against the tide of American consumerism, but it’s important to keep repeating an important truism: green building depends on following an integrated design process, on minimizing the size of the building, and on designing for energy efficiency. You can’t make a bad building green by specifying a few “green” building materials.That said, green builders are usually curious to see which products have been included in BuildingGreen’s annual “Top-10 Green Building Products” list. Although a few of their chosen products are intended chiefly for commercial construction, residential builders will find products on the list that are worth considering. RELATED ARTICLES Nov. 2013: BuildingGreen Names Year’s Top Ten Products Oct. 2011: Top 10 Green Building Products Nov. 2009: Top 10 Green Building Productscenter_img The BuildingGreen Top-10 Green Building Products for 2013WUFI software from Fraunhofer IBP and Oak Ridge National Laboratory. Understanding how moisture moves through building assemblies is critical to their long-term durability and performance. But moisture and heat flows are highly complex, and sophisticated software is required to model performance. WUFI (for “Wärme and Feuchte Instationär,” or transient heat and moisture) is a family of PC-based software tools developed by the Fraunhofer Institute for Building Physics in Germany and Oak Ridge National Lab in the U.S.. The software calculates heat and moisture transfer in multi-layer building components exposed to various climate conditions, and has been used in the development of smart vapor retarders.Atlas CMU block with CarbonCure. The production of portland cement, the main ingredient in concrete, results in approximately 5% of the world’s anthropogenic CO2 emissions. Though concrete sequesters some of that CO2 during curing, primarily on the surface layer, the CarbonCure Block System significantly improves this process by taking CO2 supplied from local industrial sources and injecting it directly into concrete masonry units (CMUs) during production using a specially designed mold. Atlas Block is using the CarbonCure system primarily to reduce the carbon footprint of its products, but injecting CO2 into CMUs during manufacture also improves their strength, reduces the amount of portland cement required, and speeds curing.Amorim expanded-cork boardstock insulation. Expanded Insulation Cork Board is 100% natural, rigid insulation material produced from natural cork — bark from an oak tree native to the western Mediterranean region. The cork bark can be harvested from mature trees every nine years without damaging the trees. To produce rigid board stock insulation, cork granules are steam-heated in an autoclave, which expands the cork and activates a natural binder, suberin, contained in the cork; additional binders, flame retardants, or other chemicals are not used in production.GBA readers will remember that Alex Wilson posted a blog about Amorim cork insulation in August 2012. Amorim cork insulation is being distibuted in the U.S. by several distibutors, including Small Planet Workshop in Olympia, Washington.Proglaze ETA Engineered Transition Assemblies from Tremco Commercial Sealants & Waterproofing. For commercial building applications, Proglaze ETA Engineered Transition Assemblies from Tremco Commercial Sealants & Waterproofing is a complete system comprised of sealants, membranes, primers, and flashings (all its own products) and insulation and sheathings (from other manufacturers) designed to integrate well together. These aluminum and silicone components are designed to bridge between windows and other wall openings and sheet membranes in the field of the assembly. The system is designed to last 50-100 years.LoE-i89 glazing from Cardinal Glass Industries. Traditionally, there have been two types of low-e coatings: vacuum-deposited (sputtered) “soft-coat” silver layers and pyrolytic “hard-coat” indium tin oxide layers. Soft-coat low-e has to be protected from abrasion or the elements, so is only installed on a protected surface inside an insulating glass unit (IGU). Glass with hard-coat pyrolytic coatings are typically noticeably tinted and have a “pebbly” surface-texture that is hard to clean. A new coating from Cardinal Glass is a sputtered indium tin oxide hard-coat that can be installed on an exposed surface of an IGU. This option allows two low-e coatings to be used on a double-glazed IGU, and it enables a double-glazed window to achieve a level of performance that was previously achievable only with triple-glazing.Viridian Reclaimed Wood. Huge quantities of wooden pallets, crates, and packing materials used to ship goods to the U.S. are discarded daily, wasting a valuable resource and clogging our landfills. In its Oregon facility, Viridian Reclaimed Wood processes these materials from the Port of Portland and then creates flooring, tabletops, paneling, veneers, and other products for use in commercial and residential buildings.GeoSpring hybrid electric water heater from GE. The 50-gallon GeoSpring has an energy factor of 2.35 in hybrid mode, and has a first-hour rating of 63 gallons. It offers four operating modes, ranging from all electric-resistance (using two 4,500-watt elements) to all heat-pump operation. Among stand-alone heat-pump water heaters, the GE GeoSpring is the quietest, at just 55dB (though this is still noisier than most refrigerators); the product is American-made in GE’s Louisville, Kentucky factory; and it carries a limited 10-year warranty.Haiku by Big Ass Fans. Haiku ceiling fans, manufactured by Big Ass Fans, have brushless, electronically commutated DC motors for increased energy efficiency. Designed for both residential and commercial applications, Haiku ceiling fans use 2-30 watts, significantly exceeding Energy Star requirements.XS-P Series streetlight from Cree Lighting. Cree’s XS-P Series LED street and area light incorporates Cree LED light engines and BetaLED’s NanoOptic Precision Delivery Grid optics to deliver 100 lumens per watt of either 4000K or 5700K light precisely onto the ground where needed.Cyber Rain irrigation controllers. Cyber Rain systems use local weather data along with plant, sprinkler, soil, slope, and sun exposure data to calculate evapotranspiration (ET) and provide just the right amount of water to maintain the health of different plant species and avoid overwatering. The controllers are linked to “cloud”-based software via the Internet or directly through a USB port, and can be accessed remotely for real-time adjustments using smartphones or other remote devices.For more information on these products, visit the BuildingGreen website.last_img read more

first_imgzoomImage by WMN Classification society American Bureau of Shipping (ABS) granted approval in principle (AIP) to Hudong-Zhonghua Shipbuilding’s large LNG carrier with MARK III Flex membrane cargo containment system.Specifically, the Chinese shipbuilder received the approval for its 174,000 cbm GTT MARK III Flex design.“ABS is pleased to award Hudong-Zhonhua this AIP for their design to help meet the industry’s diversifying LNG shipping requirements, in this growing segment,” Vassilios Kroustallis, Vice President Europe Regional Business Development, ABS, commented.He added that the classification society continues to review advanced LNG designs.“Working with ABS through the AIP process we have demonstrated our ability to meet our clients’ requirements for more efficient LNG vessel design,” Chi Benbing, Vice President, Hudong-Zhonghua, said.Through this partnership with ABS, Hudong-Zhonghua can now offer its clients designs using both GTT membrane containment systems, MARK III Flex and NO 96 series.This allows the Chinese shipbuilder to use different kinds of cargo containment systems to best meet diversified requirements throughout the LNG carrier’s life.In December last year, Hudong-Zhonghua also received AIP from ABS for its very large ethane carrier (VLEC) concept. The VLEC is equipped with a specialized membrane cargo containment system suited to carry liquid gas cargoes such as ethane and propane.last_img read more

Report Barcelona and Carlos Vela reach a loan agreement

first_imgAccording to an explosive report from Diario Sport, FC Barcelona has reached a loan agreement with Carlos Vela for the rest of the season.It was just this week when we found out that Carlos Vela was the unknown player whom Barcelona was after to replace Munir’s exit, a report from this Friday suggests that the club and the player’s agent have reached a loan agreement for the rest of the season.The Catalan club still doesn’t completely close the deal because they are still talking specs about the whole situation, as Los Angeles FC refused to sell the player because they still consider him one of the most valuable players in MLS and they believe that he has a bright future ahead of him in the United States as a franchise professional.But the American club also believes that having some of their best player on loan during their break will help them improve their level of performance and bring it back to the MLS in order to bring a more spectacular style of football.But FC Barcelona also has another ace under their sleeve, a mystery player that they have refused to announce so far with whom they are currently also having meetings to see if he would be keen on coming to FC Barcelona for the rest of the season.#NoticiaSPORT | Acuerdo total con Vela a la espera del último ‘tapado’ https://t.co/3GPZaojaLB pic.twitter.com/OFqHz2i8Pj— Diario SPORT (@sport) January 18, 2019The main problem for Carlos Vela is he completely accepted to play for Barcelona, is the fact that he would have to come accepting a series of details that he may not like.For starters, having a player like Luis Suarez as the main striker for the squad is something that gets in the way of Carlos Vela’s possible wishes to feature more for Barcelona.The Mexican would need to come under the condition that he has to take a back seat and only play when manager Ernesto Valverde decides to rest the Uruguay international for less important matches throughout the season, Vela is coming from a start-treatment situation in Los Angeles and adapting to this environment would be slightly difficult for him is he doesn’t understand where he stands in the food chain.There is no way that he will succeed in a club like Barcelona if he comes in with a “prima donna” attitude thinking that he can take the spot from one of the best strikers of the last 10 years, the upside of all this is that Valverde himself has vouched for the Mexican’s arrival because he truly believes that he can help them out for the remains of the season.Report: Barcelona is rumored to be interested in #LAFC forward Carlos Vela. 👀 https://t.co/hEcHQIFJd1 pic.twitter.com/r4HhLxCZO2Sergio Ramos, Real MadridZidane reveals Sergio Ramos injury concern for Real Madrid Andrew Smyth – September 14, 2019 Zinedine Zidane has put Sergio Ramos’ availability for Real Madrid’s trip to Sevilla next weekend in doubt after withdrawing him against Levante.— Major League Soccer (@MLS) January 18, 2019Another thing to consider is Carlos Vela’s family situation, as his wife is from Spain and she would be keen on returning to the country at least for a good part of 2019 in order to keep raising the son they have in the country he was born.If the deal finally goes through between Barcelona and Carlos Vela, it would be because the club wasn’t able to reach this agreement with the mystery player they have refused to reveal so far, or because Vela simply doesn’t want to do the whole “being a sub” act when he is already the star of a club in a different league.But then again, giving up the opportunity to play for a club like FC Barcelona is something that any player would be crazy to refuse.Vela should give a call to Javier ‘Chicharito’ Hernandez and ask him about the experience he had when he played for Real Madrid on loan for a single season.The former Manchester United player is a great example that this scenario can be possible, Hernandez played there for a few months and it was one of the most rewarding experiences of his career.Vela as well could tell his grandchildren that he played alongside Lionel Messi at FC Barcelona, just like ‘Chicharito’ can tell his grandchildren that he played alongside Cristiano Ronaldo at Real Madrid.Barcelona are said to be interested in signing former Real Sociedad striker Carlos Vela in January. pic.twitter.com/IgC6qJmwzy— Lilian Chan (@bestgug) January 17, 2019If the deal goes through for Carlos Vela, which position do you think suits him better?

KevinPrince Boateng set to make Barcelona debut tonight

first_imgNew Barcelona signing Kevin-Prince Boateng could make his debut in tonight’s Copa del Rey clash against SevillaThe 31-year-old forward made a shock loan transfer to Barcelona on Monday from Serie A side Sassuolo until the end of the season with the option of it becoming a permanent deal this summer for €8m.Barcelona’s decision to sign Boateng came in light of Munir El Haddadi’s departure to Sevilla earlier this month with Paco Alcacer leaving Camp Nou last summer for Borussia Dortmund.This had left Ernesto Valverde’s side short of centre-forward options with Luis Suarez bearing most of the workload this season.Now Barcelona have confirmed that Boateng has been named in a 19-man squad for the trip to the Ramon Sanchez Pizjuan.The unsettled Denis Suarez, who has been heavily linked with a loan move to Arsenal this month, has been left out of the team for tonight’s first leg quarter-final clash.David Villa, SpainQuiz: How much do you know about David Villa? Boro Tanchev – September 14, 2019 Time to test your knowledge about Spanish legendary forward David Villa.Also missing is Lionel Messi, who has been handed a rest by manager Valverde in favour of giving some academy stars like Riqui Puig a chance.Speaking ahead to the tie on Tuesday evening, Valverde warned his Barcelona team to not lose their focus as they chase a fifth successive Copa del Rey title this season.“Our analysis was based on the fact that they are a strong rival at home and in the knock-out ties they have always been very solid,” said Valverde in a press conference.“Sevilla are a great team with experience in the qualifying rounds and have the measure of this competition. They will be a tough team in this tie.”The last time these two sides met in the Copa del Rey came in last season’s final, which saw Barcelona thrash Sevilla 5-0 at Atletico Madrid’s Wanda Metropolitano to claim a 30th crown.The Sevilla and Barcelona Copa del Rey match will begin tonight in Andalusia at 21:30 (CET).last_img read more
