A New Green Building Rating System

first_imgJust what does ecoSelect require?The checklist of requirements is not posted in a public area of the ecoSelect website, but a partial list is available at the Green Builder Coalition website. A chart available there compares ecoSelect to the 2009 IECC and the 2009 International Residential Code, calling out sections that are either above or below those codes, or not mentioned at all.Bob Kingery, ecoSelect’s co-founder and president, provided the checklist of requirements for certification (see Images #2 and #3, below). Among them:Air leakage of 5 air changes per hour at a pressure difference of 50 pascals.Window U-factors and solar heat gain coefficients by climate zone.Duct insulation in unconditioned spaces.EPA WaterSense lavatory faucets and toilets.Energy-efficient lighting.Energy Star dishwasher and refrigerator.Insulation must be installed to RESNET Grade II requirements, but there are no specific levels of insulation required in the building envelope. Kingery said it would be up to the homeowner or builder to require a certain HERS rating for the building. For builders who find established green-building rating systems too daunting, a startup called ecoSelect is offering a simplified building standard that will be easier and cheaper to follow.Mike Collignon, the executive director of the non-for-profit Green Builder Coalition, writes in an online post that ecoSelect fills the gap between basic building code compliance and more complex requirements of other green-building programs.“More and more builders are recognizing the importance of creating a unique ‘green’ identity, but navigating through the myriad of green building programs can be overwhelming,” Collignon writes. “Similarly, even knowledgeable home buyers are confused by the plethora of options.”A common complaint from builders who’d like to market green houses is that established programs lack a “simple checklist of measures that help them ‘get it done,’” Collignon writes. EcoSelect, he adds, is less expensive, easier-to-follow, and easy to market.It’s already a crowded field. In addition to the well-established LEED for Homes and the National Green Building Standard, builders can choose from a long list of green-building standards: Passivhaus, the Living Building Challenge, Energy Star, plus a variety of regional and state programs. A pass/fail standard for complianceEcoSelect deals only with new construction, and makes requirements in only three areas — energy, indoor air quality and water — with a checklist of prescriptive steps that are mostly rated on a pass/fail basis. The entire checklist is on a single page.Most of the requirements are equivalent to the 2009 International Energy Conservation Code, Collignon writes, and because most of the requirements for certification are already in model building codes in one form or another, “it doesn’t take building much above code to achieve certification.”Builders who want their houses certified work with a HERS rater, who handles required inspections and testing. There are no points to add up, and the documentation, Collignon says, is simple.“All that is needed are the plans, REM file, an ecoSelect performance label, a picture of the home and a completed checklist,” he says. Costs for a small-volume builder would average between $500 and $600, most of which is paid to the HERS rater, Collignon writes.center_img An alternative to Energy StarSo why one more rating system when there are already so many out there?“We are finding great success with builders who are not interested in moving forward with the continual changes to Energy Star,” Kingery said in an email. “Our sales training and marketing support are great value adds for both raters and builders too.”Michael Chandler, a North Carolina builder and frequent contributor to GBA, said much the same thing. EcoSelect emerged as an alternative to Energy Star because the government program was “constantly changing the rules and making it increasingly challenging to participate without offering any differentiation between the old Energy Star and the new,” he said in an email.“All we really want is a Duct Blaster and blower door testing and a certified HERS rating, so if we don’t play with Energy Star then we just find it a lot easier to go ecoSelect along with the [National Green Building Standard] green rating,” Chandler continued. “It’s not an alternative to the National Green Building Standard, just a lot less cumbersome alternative to Energy Star.”Kingery said more than 1,500 homes have been certified to date in the Southeast. EcoSelect hopes to expand into new territory, includuing Colorado and the Minneapolis area.last_img read more

On Latent Dissatisfaction and Dissatisfaction

first_imgThe primary reason insight-based selling is so hot right now is because there is so much latent dissatisfaction. It’s difficult to create opportunities without a reason to change.Your prospective clients have plenty to be dissatisfied about, but they may not yet be aware of how much better their results could–or should–be. When they’re stuck, it makes sense to create that awareness. It is an effective choice for creating an opportunity, and it can set you apart. Especially when you have something compelling to offer in the way of improvement.But this does not mean that you always need to provide insights. Some of your prospects are already dissatisfied. They know what they need to improve, they know how they need to improve it, and they know what they need from a partner. You can create an opportunity by collaborating with these prospects and by helping them with a solution. There isn’t any reason to pretend that they have latent dissatisfaction so you can teach them something, unless it directly helps them get what they already want or establishes new priorities.But there is more to be gained from helping prospects who are dissatisfied and know it. You can gain powerful insights and knowledge from them—if you are open to learning instead of teaching. You can share what you’ve learned from these clients with other prospects, some of whom will benefit greatly from what you learned.You take your prospective clients where find them. If they aren’t dissatisfied, you help them see new possibilities. If they are already dissatisfied, you collaborate with them and help the find a path forward. All the while learning as much as you can so you gain the business acumen and situational knowledge to help others more effectively in the future.QuestionsWhat are the problems your prospective clients have but have not yet recognized?How do you help them recognize the better performance that is available to them?What have you learned from prospects who were dissatisfied and knew exactly what they needed?What have you learned from serving some clients that would benefit your prospects?last_img read more

Ind vs Eng, Bristol ODI: Toss delayed due to rain

first_imgDhoni-CookTheir morale battered by the Test series debacle, India would look to make a fresh beginning and salvage lost pride when they take on England in a fivematch ODI cricket series starting in Bristol on Monday.However, they’ll need to keep their eyes on the sky and pray hard for the match to go ahead as there is a 100 per cent chance of rain in Bristol.On one hand, the Indians will be distracted by the 1-3 series loss in the Test series and will want to do well in the ODIs, while on the other, they will also need to balance their approach keeping next year’s World Cup in mind.That tournament, to be hosted by Australia and New Zealand, is just six months away. From here on, every ODI played by the Indian team will be a preparatory step towards defending their 2011 crown Down Under.And to do so, they will be evaluating players in the three ODI series between now and the World Cup – in England, at home against the West Indies and then in the tri-series on the Australian tour.Already, the Indian selectors have taken stock of the situation at hand and the 17-man squad is a reflection of their thoughts. Sanju Samson and Karn Sharma represent their line of thinking in that the squad will need an additional wicket-keeper as well as a third spin-bowling all-round option.But there is a question-mark over how many opportunities these two youngsters will get in the current five-match series. This is because the middle-order and all-round spin slots have enough contenders at the moment.advertisementRavindra Jadeja and R. Ashwin will fill up the two spin options in the playing XI. Earlier this year, in the fourth ODI at Hamilton, Stuart Binny was introduced as an alternate and his exploits in Bangladesh he will be a factor in conditions that assist swing.However India skipper M.S. Dhoni is a little circumspect about using four medium pace options as it slows down the over-rate. It will be interesting to see if he will opt for two spinners straight-away, irrespective of the conditions in Bristol, given that Binny didn’t bowl in the warm-up game against Middlesex on Friday.On that day, Bhuvneshwar Kumar and Mohammad Shami bowled short spells and it was a clear sign that the management was looking to preserve them. ‘TEST OF CHARACTER’ Meanwhile, senior batsman Suresh Raina feels these ODIs will be a test of the Indians’ character.Claiming to have done his bit to infuse some positivity into the beleaguered team, Raina said: “The team is going through a difficult phase and it is time for us to show character. It can be difficult sometimes to move on from such a defeat but you have to fight your way out of it when you’re playing at the international level.”I always try to maintain the cheerfulness in the team, on and off the field. I am the first person to run to the bowler or fielder when a wicket falls,” he told the official BCCI website.last_img read more

Interruptible 3D printing method wins Gehry prize w Video

first_img Robot arm at MIT will weave its own web (w/ Video) The prize is given to those who can demonstrate exceptional thesis projects. The couple won for their method of 3-D printing that allows the user to make changes to the design in progress.In 3-D printing an object is created by laying down successive layers of material that can render finished objects.3-D Printers make objects in three dimensions, layer by layer, which may be only microns thick. The model that is destined for replication has usually been fully resolved. The Phantom Geometry method allows the user, in contrast, to print outside the specifications of a given 3-D mode. Fundamentally the Phantom Geometry method is designed to create a physical model of streaming information. Using advanced robotic arms, the von Hasseln team proceeded to manipulate the model as it was being printed. According to their idea, as a printed product emerges, the designer can make alternations to the design in-progress, and in so doing change the downstream architecture of the printed product.Their system has a UV light projector, a special photo-sensitive resin, and controlled robotic arms from SCI-Arc’s Robot House. One robotic arm supports a projector at a stable height, while a second holds a vat of resin. 
The second arm moves the vat into the projector’s light beam of light. The designer tells the computer where and when to expose that vat to the projector’s rays. The designer is free to interrupt the process and change the model while it is being printed. As a result, one can work with a fabrication system that relies on real-time feed-back and feed-forward mechanisms, they said, and is therefore “interruptible and corruptible at any time.”As they explain in their own words, “The system uses UV light from a modified DLP projector to continuously and selectively cure photo initiated resin within a shallow vat system we developed for the project. The cured part is simultaneously and continually pulled away from the vat, allowing un-cured resin to flood in beneath it to be subsequently cured. The result is the material reification of streaming data that emerges along the motion path of the Staubli robot maneuvering the vat/projector apparatus.”SCI-Arc is an independent architecture school. The school’s Robot House is a cross between studio and shop, academy and industry, utilized as a research space for experimentation. Students have access to a multi-robot platform that includes six Stäubli robots, each with a full sphere of motion, operating in one flexible configuration, or in what the school calls a multi-robot work cell.
