Passivhaus on Spec in Boston

first_imgA step-by-step progress reportThe company has created a construction blog that walks visitors through the process, beginning last September when the building site was an overgrown lot through February when builders were working down their punch list.There are 21 entries in all, at least so far, and although you’ll only get a single photo and a little text at each one, you can see major steps along the way.Some of the technical highlights:A shallow frost-protected slab insulated with 8 inches of expanded polystyrene (EPS) for an R-value of 32. The sides of the footings are insulated with 4 inches of EPS (R-16).Above-grade walls are balloon-framed on the outside, 24 inches on center, with a second framed wall inside of that carrying floor joists for the second story. The walls are connected with gusset plates and spanned by window wells. Exterior walls are insulated with 17 inches of blown-in cellulose (R-59).The truss-framed roof is insulated with 2 feet or more of cellulose for an R-value of 84.Windows are triple-glazed Schuco units with a U-factor of 0.176 and a solar-heat gain coefficient of 0.50.Domestic hot water is provided by a Kingspan FPW30 solar thermal system with a 119-gallon tank.Space heating and cooling are provided by a pair of Mitsubishi Mr. Slim ductless minisplits, each with a capacity of 9,000 BTU/h. A Zehnder Comfoair 350 heat-recovery ventilator provides fresh air.Airtightness was measured at 0.33 air changes per hour at a pressure difference of 50 pascals. Placetailor used Siga Wigluv tape to seal the sheathing seams and Siga Corvum tapes to reduce air leakage around the window frames.You’ll find many more details at the Rocksberry website, including descriptions of interior finishes and exterior cladding.One neat trick involved the exterior rainscreen. Siding on much of the house runs vertically, so Placetailor looked for rainscreen furring that would allow air to circulate freely (solid material run horizontally would block the flow of air). They settled on a twin-wall PVC product manufactured by Coroplast they could get through a local supplier. The Boston design-build group Placetailor is wrapping up work on a single-family house in the city’s Roxbury district that was built on spec to the Passivhaus standard. The has was sold even before work was completed.The two-story house at 55 Marcella Street has three bedrooms, 2 1/2 baths, and a total of 1,450 square feet of conditioned space. It’s right around the corner, literally, from a high-performance four-unit townhouse on Highland Street that was completed last year. Placetailor also had a hand in that one.Placetailor strategic director Declan Keefe said the house on Marcella recently sold for $572,500. The house went on the market during rough framing and was under contract before Placetailor had finished plastering the interior.The buyers apparently don’t care whether their new house is officially certified as a Passivhaus, and Keefe says Placetailor is still discussing whether to pursue official certification on its own. The house, which Placetailor calls the “Rocksberry Passive House,” was built on an infill lot right across the street from a small city park and not far from public transportation and bike paths. The price is rightThe property was snapped up quickly, although Keefe says the eventual buyers weren’t shopping specifically for a Passivhaus building. In fact, they hadn’t been aware of the Passivhaus standard.Whether the economy is picking up steam, new single-family homes in the neighborhood are rare, or high-performance homes are more attractive than conventional housing, the Rocksberry House apparently went for an above-average price.Keefe said the house sold for $325 per square foot in an area where anything above $300 per square foot is uncommon. Even the high-performance “E+” units around the corner sold for $269 per square foot.Placetailor already has two additional Passivhaus projects in the works, including a two-family condo, also to be built on spec, and a three-family Passivhaus rental that will be built to another firm’s design.last_img read more

Leading From Outside Your Glass House (A Note to the Sales Manager)

first_imgSales managers are always complaining that their sales people don’t read, don’t study and don’t work on improving themselves as sales professionals. This criticism is 100% valid. Most salespeople don’t (except, of course, those who continually show up here!)Here are three ways you can help change this in your salesforce.Lead by example: If you want your sales force to take their personal and professional development seriously, give them an example to follow. Let them see you reading books on leadership. Let them see you reading books sales effectiveness. Let them see you attending webinars and conferences where you learn more about leading a team and more about selling well.Be transparent and vulnerable about your own development: It’s easy for you to see each member of your sales team’s blind spots (even though it’s way more difficult now that so many people work from home or from remote locations, you’re still probably engaged enough to see what your sales team needs to do to improve). The profession of sales management is a lonely one. Who is close enough to help you see your blind spots? If you believe that a coach or a mentor can help the members of your sales team improve, imagine what it could do for you. Let your team know what you’re doing to get feedback on your performance and the changes that you are making to improve your ability to help them succeed in their roles.Share what you are learning: Maybe you’re busy doing all these things already. But does your sales team know it? Make visible at every opportunity the fact that you’re working to improve yourself. As often as you can, share with your team the latest information that you acquired from reading, from a webinar, from conference. Tell them the changes that you are making based on what you’ve learned. Ask them to share their thoughts and opinions on the changes you’re making, and nudge them to share what they’re reading. Ask them to share their challenges and invite them to share ideas with the rest of the group about how those challenges might be overcome.If you are throwing stones from inside the glass house, step outside and lead your team. If you’re already way outside the glass house, make sure your team knows it.QuestionsWhat are you doing to lead your team on the personal and professional development front?Do you make public all of the ways you are working to improve yourself?What do you want your team to do to improve themselves? What do you do to lead the way? Free Webinar Series! Create a culture of value creation. Signup for this free webinar!

Current crop of archers can have another shot at Olympics

first_imgIndia’s archery campaign at the London Olympics ended on a disappointing note with Deepika Kumari going out in the first elimination round to home favourite Amy Oliver.Deepika had defeated the British girl quite easily whenever they had faced off previously, but at Lord’s on Wednesday, things turned out differently.This was a totally unexpected result. Deepika did not hit any 10s when required, which is very unusual. Normally, she compensates for her low scores by shooting a large number of 10s, but could not manage to do so here.She told us after her match that she did not feel any pressure during her match. However she struggled to assess the tricky conditions.As far as the other archers are concerned, Jayanta Talukdar did not put in a good performance though he was up against a top American.Rahul and Tarundeep made it to the second elimination round, before bowing out. But they showed fight which is a good sign.Chekrovolu Swuro seemed to just give it away after being in control. She first allowed her to draw level at 5-5 and then went down in the shoot-off.In the overall picture of the archers’ performance at the Olympics, the less than perfect start also had a role. They finished quite low down in the ranking round, which could have had an adverse impact on their morale.The fact that the conditions were quite tricky can be gauged from the fact that the topranked men’s archer, Brady Ellison of the United States, lost in the second round and later tweeted that he was thoroughly confused by the wind.advertisementAfter returning to India, one needs to find out what ingredient we are missing as we fail to crack the Olympic code despite going with high hopes. We need a long term programme for the Olympics.Age is no factor in archery and if the current batch can remain fit and focused, they can have another crack at the Olympics.(The writer is a two-time Olympian and Arjuna awardee)last_img read more

World Cup Twenty20: Failure on all fronts against the Aussies

first_imgWhen a team gets annihilated by nine wickets with 31 balls to spare in a Twenty20 International , ‘what went wrong’ is a tough question to tackle, since the answer could be just about everything.As India took to the practice nets at the Colts Cricket Club ground on Saturday, the psychological effect of the defeat at the hands of Australia was writ large on the players’ faces.While it would be easy to blame Dhoni’s dropping of Virender Sehwag, Friday’s troubles went much deeper than the absence of one star batsman. Sehwag sat out of practice on Saturday as well. He played a bit of football, and just sat and joked around.The other six looked listless, and nothing summed up the Indian innings better than Irfan Pathan’s 30-ball 31 at the top of the order. The all-rounder got off to a flying start against the pace bowlers, but once spinner Brad Hogg was introduced at the end of the Powerplay, he could barely get the ball off the square. He also survived a couple of close shouts for LBW, and seemed to withdraw into a shell.Once the in-form Virat Kohli had perished for just 15, the middle-order found itself in the unfamiliar position of having to rebuild without their star batsman around.They flunked the test, with Yuvraj Singh succumbing to a bouncer and Rohit Sharma to his Achilles Heel, the in-swinging delivery.The batsmen just didn’t seem intent enough to hit the big shots and play to their strengths, letting the Aussies put the choke hold on them.Still, 140 for seven was a score on the board, and a couple of early wickets on the slow track would’ve put the untested Australian middle order under pressure.Whatever pressure Zaheer Khan created with a strong spell of fast bowling was let off by Ravichandran Ashwin at the other end. The fifth over was the key, as Ashwin gifted the dangerous Shane Watson two long hops that were duly deposited beyond the on-side boundary.Piyush Chawla bowled two loose deliveries to Watson and watched them disappear; Harbhajan Singh pitched it up to David Warner twice and then picked up the shattered bits of his confidence from the cow corner fence.For swashbuckling batsmen like Watson and Warner, a couple of freebies are enough to feel good about life, and Dhoni’s strange tactical decision not to bowl his best new-ball bowler, Pathan, till the 10th over was another factor. When he did get the ball, he bowled long hops, and conceded 19 runs. There were also misfields, a dropped catch, and terrible body language once the going got tough.advertisementlast_img read more
