Happy Birthday EarthCaching – EarthCaches Turn 8 Today

first_img“The Pinnacles” EarthCache in Malaysia (GC19A54)The world’s first EarthCache turns eight-years-old today.  Saying “Happy Birthday!” is as easy as logging an EarthCache. Chances are there’s one close to where you’re sitting right now. There are plenty of EarthCaches, think thousands and thousands, around the globe. But that wasn’t the case back in 2004.“Earthcache I – a simple geology tour of Wasp Head” (GCHFT2) triggered a seismic movement in geocaching. The first EarthCache was located in Australia. It was placed by geoaware on January 10, 2004. Since then more than 17,000 EarthCaches have been published, popping up on every continent on the planet.Each EarthCache must share specific characteristics before being published. There’s no physical cache. At every EarthCache, geocachers learn about the forces that sculpted the earth. EarthCaches showcase volcanoes, seismic fault lines, salt flats, bizarre rock structures and more. Each Earthcache reveals how scientists understand our planet.EarthCache at a green sand beach in Hawaii “Olivine” (GC1M15H)To log an EarthCache geocachers must demonstrate to the cache owner what they learned about a specific geological feature. Geocachers might measure a rock structure or record a tidal movement. At the EarthCache “Olivine” in Hawaii, geocachers must answer questions about the unique green grains of sand.EarthCaches are gaining in popularity as they grow older and more established in the geocaching world. Organizers are even hosting the first International EarthCache Event (GC33E6X) this year. It’ll take place in September near Portland, Maine, USA. More than 250 geocachers have already logged a “Will Attend.”You can learn more about EarthCaching by watching the video below.[vsw id=”f11fxuNsaE8″ source=”youtube” width=”425″ height=”344″ autoplay=”no”]Share with your Friends:More SharePrint RelatedInside Geocaching HQ Podcast Transcript (Episode 13): EarthCachesMay 10, 2018In “Community”Your Path to Platinum EarthCachingFebruary 11, 2015In “Community”The Creator of EarthCaching talks about the 10th AnniversaryJanuary 10, 2014In “Community”last_img read more

Multifamily Green Building Certification Still Has Issues

first_imgMuch of my work these days involves certification of multifamily buildings, and, thanks to a boom in apartment construction, my partner and myself are staying occupied.The one major contrast from single-family residential work, with which I am most familiar from my days as a contractor, is the long lead time. I still find it amusing that I sign a contract, have an initial start-up meeting with the developer and contractor, and often don’t see the project for another year or more, when the builder is ready for our insulation and air-sealing inspections.Due to this lag from start-up to our inspections, we can be suddenly quite busy inspecting buildings — often 3 or 4 in a single week. Just recently we inspected buildings in both Rome and Athens — but, unfortunately we never left the state of Georgia. Insulation is still the biggest challengeDepending on the certification program (we work with LEED for Homes, the National Green Building Standard, EarthCraft, Energy Star, and Enterprise Green Communities), we have to confirm that insulation installation meets either Grade 1 or Grade 2 specifications for these projects to be certified. RELATED ARTICLES Whole lotta firing going onOur enforcement of insulation standards leads to a lot of friction on the job site. When you walk through a job and pull out about 80% of all the insulation for correction, you get some pushback.Insulators complain that they aren’t being paid enough, builders complain that we are delaying their schedule, and we complain because we get all itchy from touching insulation all day. We have caused insulators to quit and get fired, and we have even been fired as consultants from a project because the builder blamed us for their delays.The part about this that bothers us the most is that while we are enforcing green building standards, typically these standards are no more stringent than the energy code and the insulation manufacturer’s instructions. These instructions call for the equivalent of Grade 1 and all necessary air barriers.Unfortunately, the baseline we are compared to is so far below these standards that many builders cannot easily get to where they need to be. It’s the air leakage, stupidBeyond the quality of the installation, we also find missing air barriers throughout the multifamily buildings we inspect.Attic kneewalls (those walls that separate conditioned space from unconditioned attics) require rigid air barriers on the attic side and (in Climate Zone 3) a minimum of R-18 insulation. These details are rarely identified in the plans and specs, so builders don’t budget for this extra work. Elevator shaft, corridor, and stairwell walls need to meet the same installation specifications as exterior walls, and, due to scheduling issues, these are often insulated and covered with drywall before we get to inspect them. I have had contractors remove lots of drywall to have the insulation inspected (and corrected) in order to meet certification requirements.Architects install all sorts of bump-outs that create chases in the exterior walls, many of which do not get the proper air barrier installed. I can’t count the number of times I have pulled out a piece of insulation to check the installation only to find a big hollow cavity behind it, missing all the required air sealing and essentially leaving a gaping hole in the building envelope. There is some hopeGreen consultants who provide certification, are, in most cases, viewed as a necessary evil, often ignored by most of the construction and development team.Raters and green consultants should be welcomed as key members in a project team – on an equal footing with the architect, engineers, builders, and others.While we do see some progress – the occasional call from an architect or developer before their plans are complete – this does not happen as frequently as it should. When the design and development team understands what green professionals have to offer, and bring them in very early in the process, we will start seeing more buildings that are truly high-performance.center_img In our initial meetings, we stress the importance of this, and urge our clients to consider something other than batt insulation due to the challenges of meeting the installation quality requirements. Unfortunately, the budgets rarely allow for these upgrades, so we constantly find ourselves struggling with the installers.We always schedule a meeting before insulation work starts to review our requirements and to confirm that the installer can meet them. This is the point at which we start hearing the falsehoods. The managers always insist they have great crews who are fully trained to meet the Grade 1 standard, but inevitably when they show up on site, no one has discussed installation quality with them and they just start doing their regular old Grade 3 work.I can’t blame the installers (at least most of the time), as many are paid on a piece-work basis and in most cases, they are not only not being paid enough for the quality work we need, chances are they were never told that the job required Grade 1. Be afraid — be very afraid — of “value engineering”One ongoing problem we find is “value engineering” during the estimating or construction process to lower construction costs — a common practice in the building industry.The problem arises when the individual making the decision to make a specification change isn’t aware of the implications on certification. They might be able to save $100,000 or more by swapping out windows in a building, but, if the new windows don’t meet the minimum requirements, the building may not be able to be certified.If there is a contractual agreement to have the building certified, a seemingly small change may end up costing more than it saves.

AUSTRALIA OPENERS WATSON, HADDIN AT CREASE VS INDIA

first_imgAustralia openers Shane Watson and Brad Haddin are at the crease against India in their World Cup quarter-final match in Motera on Wednesday. Live ScoreAustralia openers Shane Watson and Bad Haddin are at crease against India in the second World Cup quarter-final match at the Sardar Patel Stadium in Motera, Ahmedabad, on Thursday.Earlier, Aussie skipper Ricky Ponting won the toss and elected to bat. Not an unusual decision considering that seamers won’t have much bounce and carry and it is a good batting wicket. The wicket looks dry and there will be some turn in offer for the spinners.In World Cups, India and Australia have played each other nine times. Australia have won seven times and India have won twice. However, in the knock-out stages of ICC events, they have met four times where India have won thrice and the Australia just once. At Motera, they have played twice and both have won one game each. Teams -India: Sachin Tendulkar, Virender Sehwag, Gautam Gambhir, Yuvraj Singh, Virat Kohli, Suresh Raina, MS Dhoni (capt./wk), Ravichandran Ashwin, Harbhajan Singh, Zaheer Khan, Munaf Patel  Australia: Shane Watson, Brad Haddin (wk), Ricky Ponting (capt.), Michael Clarke, Cameron White, Michael Hussey, David Hussey, Mitchell Johnson, Jason Krejza, Brett Lee, Shaun Taitlast_img read more
