Passive House: What Do You Think?

first_imgPassive House Project in Asheville, N.C., Poses Many Questions and LessonsCheck out floor plans, site plan, a model and details plans of this project.Over the next few months, I will be following an interesting infill project here in Asheville. It’s an 842-square-foot house, following the Passive House Institute standards.I checked out the project in West Asheville for the first time last week. The homeowner is a single fella who is contracting the home himself, with a fairly flexible time line. That will give us an ongoing opportunity to dissect different aspects and stages of the project very closely, and hopefully engage the readership to weigh in with philosophy, experience, and opinions. I’ll be shooting some video of the project as well, interviewing the architects and owner, so stay tuned. I live close by, so I will follow the project through to completion and habitation, chronicle a comparison of modeled to actual performance, and share the results of the HERS testing as well.The home belongs to Chris Otahal, a structural engineer at Kloesel Engineering here in Asheville. He is working with Aaron & Calder Wilson at Wilson Architects, a husband-and-wife architecture team. I have had the pleasure of working with Aaron & Calder on a number of projects, including my own home. They are a very talented couple and bring a deep understanding of green building to this project, though this is their first Passive House.Before beginning, Chris sought information from the US Passive House Institute in Urbana, Ill., which provided the team with energy modeling, insulation strategies, and HVAC sizing. (I’ll share some specifics on the services in later blogs.) With the Institute’s info and some further modeling, the team concluded that this particular design would be cooling driven—there will be more traditional energy used for cooling the home than for heating it. To keep the heating load as low as possible, the team implemented such strategies as airtight construction, superinsulation, passive solar design, and the use of custom glazing on the south side of the home (I’ll get into these in more detail in the future as well). Here’s a list of green features that the team has incorporated or will incorporate on the remainder of the project:The home has a small footprint, which minimizes land disruption and material use (the lot is .10 acres!).The structure holds a trim 842 square feet of living space.The marginal infill lot was unattractive to most, but Chris saw a diamond in the rough. The site has a stream on the south end and a sewer easement on the north end, limiting the potential building area. But Chris’s needs and the creativity of the team took the opportunity to put an interesting home on an interesting lot. The home makes use of the entire buildable area of the lot.Chris opted for a combination of triple-glazed windows, some with a low solar heat gain coefficient (SGHC), some with a relatively high SGHC.Exterior walls are 2×8 construction, 24 in. o.c. The cavities will be filled with blown cellulose, with 3 inches of rigid insulation on the exterior installed perpendicular to the studs.A rainscreen siding system was utilized, and the exterior finish will be corten steel panels attached to 1×4 furring strips.They used a high-performance weather barrier and drainage plane, VaproShield.A mini-split will be used to condition the home.They will be using a high-efficiency tanked water heater.Passive solar design utilizes large south-facing windows and limited north, east, and west glazing. South-side overhangs were properly sized.The 16-in. roof and floor TJI joists will be filled with insulation.An energy recovery ventilator will provide fresh air, pressure balancing, and preconditioning.The project is at rough stage, so it’s a great time to investigate while the walls are still open. Interior insulation will start up soon, which brings us to our first opportunity to make this an interactive blog and construction process. Chris is still deciding on the best possible insulation product or products to use for the roof. It’s a 16-in. cavity that you can think of as a clean canvas. Free your inner green building Michelangelo to share your opinions and help the team find answers to the following conundrums they’re facing:Should they install a foam skin on the underside of the sheathing?1. If so, should it be open cell or closed cell? (We are in a mixed humid climate, in the Blue Ridge Mountains. It’s a fairly unique climate: humid, some snow, some heat.)2. Should another type of insulation be used, either by itself or in conjunction with foam?3. What would the most effective depth be, taking energy efficiency and budget into consideration?4. Should the roof be vented or unvented?Here are my responses. Let me know if you agree or disagree and why:1. For air-sealing purposes, I would opt for 3 to 5 inches of foam.2. I would choose open-cell foam for its breathability.3. I would fill the remainder of the rafter cavity with a blown-in product, possibly dense-pack, no-VOC fiberglass.4. I would fill up the cavity. The mix of the two insulation types would be less expensive than all foam.5. Unvented. It’s not necessary to vent with the use of foam insulation, which ensures that the conditioned space is pushed all the way to the exterior sheathing. The heat stays out of the envelope, so there is no need to vent hot air from the assembly.What would you like to know about this project? I plan on investigating the choice and installation of windows, exterior cladding, and mechanical systems. Do you readers have burning questions that you would love to have addressed here more than anything else in the whole, wide world? If so, take a moment to post your question. I’ll kick it around to the team and respond in subsequent blogs. In the meantime, check out the Passive House Discussion at GBA, and another at JLC.Check out pictures of the project at my Flickr page. Also, I will make a few architectural details available periodically. Here are a couple: Jamb & Corner Detaillast_img read more

The next day I was jogging on it a little and from then I knew there was a chance of me being involved [against Liverpool yesterday].”There is still swelling there now but it is solid and I felt good and I trained the day before. I was pretty positive the day before the game that I would be involved.”He added: “You have to block the injury out of your mind and focus on the game.”When I had that chance which I felt I should have scored I rolled my ankle a little bit and it felt fine. It was fine throughout the whole game. It was solid.”Your Champions League debut, you don’t want it to end so soon, but that is football, it happened, and I try to stay positive. “I looked forward to the Liverpool game and set a goal that hopefully I could get ready for that. I feel like I am a quick recoverer and we worked on it hard and I was able to get back.” last_img read more

Ohio States Storm Klein reinstated

Formerly-dismissed Ohio State linebacker Storm Klein has been reinstated to the Buckeyes’ football team. OSU spokesman Jerry Emig confirmed in an email that first-year coach Urban Meyer has let the senior back on the squad, though “he will not be allowed to play in a game until at least the third week of the season.” “As I had indicated previously, if there are any changes in the charges against Storm, I would re-evaluate his status,” Meyer said in a released statement. “The charges that would have violated our core values have been totally dismissed. I have spoken extensively to members of both families and that has prompted me to re-assess his situation and allow him back.” According to Franklin County Municipal Court records Klein pleaded guilty to misdemeanor disorderly conduct Monday morning having originally faced charges for domestic violence and assault. Klein was arrested late on July 6 after allegedly striking the mother of his child. A day later, Meyer dismissed the linebacker from the team and said in a released statement that the charges against Klein “violate the core values of the Ohio State football program.” Meyer, though, said, “If there are any changes in the charges” he would re-evaluate Klein’s status with the program. On Wednesday, Klein’s lawyer, Larry James, confirmed to The Lantern that both the domestic violence and assault charges were indeed dismissed. All that Klein faces now, he said, is 18 months of probation and court fees. If Klein has been reinstated, James added that Meyer told him any infraction “whatsoever” could still result in a penalty to pay. In his three years on the field, Klein has amassed 73 tackles in 38 games for the Buckeyes, including 45 in 2011. Before his dismissal, Klein was not listed as a starter on OSU’s depth chart. read more

Lady Buckeyes lose to North Carolina 5754

Like the men’s team, Ohio State’s women’s basketball team made a trip to the “Tobacco Road” portion of the state of North Carolina. They will bring a loss home. The No. 15-ranked Buckeyes were unable to win on the road in their visit to No. 22 North Carolina, falling short to the Tar Heels, 57-54. With the loss OSU falls to 4-2 on the season. Both of their losses have come against ranked opponents. OSU senior guard Tayler Hill scored a game-high 24 points on 9-21 shooting led OSU, but the Buckeyes’ likely could have used another scoring option as no other player reached double figures. Conversely, three different Tar Heels scored 11 points in the game. It was a close contest, but the Buckeyes had to claw their way back from a large deficit to make it a game. Midway through the second half, OSU trailed by 16 points at 44-28. With Hill leading the way the Buckeyes were able to cut the margin, and even took a two-point lead with 1:26 left to play. But the Tar Heels answered in a big way, forcing two turnovers down the stretch and scoring the game’s final five points to clinch the upset win. OSU returns home this weekend for a noon tipoff against Evansville. read more

Womens Basketball Strong third quarter pushes No 16 Ohio State to 8869

Ohio State senior guard Kelsey Mitchell (3) dribbles past defenders in the second quarter against Michigan State on Jan. 27 at the Schottenstein Center. The Buckeyes beat the Spartans 78-62. Credit: Alyssia Graves | Assistant Sports DirectorAfter coming off of a brutal loss in which Ohio State let South Florida junior guard Kitija Laksa drop 41 points on it in an 84-65 loss, the team’s main focus was to bounce back — and bounce back it did.No. 16 Ohio State (21-6, 10-3 Big Ten) went on the road and beat Illinois (9-18, 0-13 Big Ten) by a commanding score of 88-69. The Buckeyes received a lot of production from senior guard Kelsey Mitchell and redshirt senior Linnae Harper. Mitchell finished with 28 points, while Harper added a double-double with 20 points and 11 rebounds.Ohio State’s strong third quarter proved to be the difference maker. After a rough end to the first quarter and strong second quarter, Ohio State finished the third quarter outscoring Illinois 28-15. Heading into the fourth quarter, Mitchell had 21 points with the Buckeyes up 66-48.The Buckeyes came out of the gates strong, quickly jumping out to a 13-4 lead to start the first quarter thanks to a couple of Mitchell 3-pointers. That lead quickly disappeared when Illinois closed out the quarter on a 17-3 run to take a 21-16 lead after one quarter. The Buckeyes again jumped out to a strong start in the second quarter to regain a double-digit lead. However, Illinois clawed its way back into the quarter and made its halftime deficit a manageable seven points, 38-31. Ohio State’s lead at the break would have been larger had Illinois junior forward Alex Wittinger been held in check. Heading into the second half, Wittinger had 18 points on 8-for-13 shooting with eight rebounds. Wittinger finished with a double-double, 30 points and 16 rebounds.After the third quarter, the Buckeyes cruised the rest of the way. Illinois trailed significantly while Mitchell continued to drain basket after basket in the fourth. After going down 21-16, the Buckeyes outscored Illinois 67-53 the rest of the way.With three games remaining in conference play, Ohio State will look to close out the regular season strong heading into the Big Ten Tournament. It returns home to face Purdue for Senior Night at 1 p.m. Saturday at the Schottenstein Center. read more

Review England – Belgium

first_imgWith a moment of individual brilliance, Adnan Januzaj gave Belgium a 1-0 victory and the first place in Group G.The final two matches of the group stage are soon upon us…Here are the teams for #ENGBEL!#ENG #BEL pic.twitter.com/rvom0sQ4Ru— FIFA World Cup (@FIFAWorldCup) June 28, 2018Januzaj tips United to return to the top Obinna Echi – November 14, 2018 Adnan Januzaj has backed his former club Manchester United to start challenging for the Premier League title soon.Januzaj believes United need to make the…Even though first place was up for grabs, both Gareth Southgate and Roberto Martinez decided to make multiple changes to their starting lineups today in Kaliningrad. There was no Harry Kane, no Eden Hazard, no Romelu Lukaku and no Kevin De Bruyne. The lack of star power didn’t mean the fans weren’t still hoping to see an entertaining encounter.A defensive lapse allowed England to have a moment in the opening two minutes that ended with Courtois blocking a cross before it came to Jamie Vardy. Youri Tielemans blasted a long-distance strike in the 7th minute, catching Jordan Pickford a bit asleep. Luckily for England’s goalkeeper, the shot was in the middle of the net, so he made the save. A couple of minutes later, Adnan Januzaj made a few dribbles and then lobbed a cross that came to Mitchy Bashuayi. He headed the ball back towards the central area in front of Pickford and even though there wasn’t a distinct shot, the ball rolled towards the goal line before Gary Cahill cleared it just before it went in.Tielemans received the game’s first yellow card. In this contest, cards were particularly important, as they could determine the final standings in case of a draw. With this card, Belgium had two more than England overall. Another foul on Danny Rose earned Belgium’s second booking. This time the guilty party was Leander Dendoncker. Whistles were coming from all over the stadium. The fans weren’t happy. The Belgian defensive trio was passing the ball among each other, while the English players refused to press. It was more than obvious both teams were satisfied with the current situation.Gareth Southgate decided to save his main defender’s energy and replaced John Stones with Harry Maguire at the half. In the 51st minute, Adnan Januzaj’s individual brilliance gave The Red Devils a 1-0 advantage. He dummied Danny Rose and then curled a beautiful left-footed shot, leaving Pickford with no choice but to take the ball out of his net. Belgium took over first spot in Group G with the goal. Later on, Thomas Vermaelen suffered a cut on his eyebrow after an aerial duel with Jamie Vardy. Marcus Rashford missed from an ideal one-on-one situation with the goalkeeper in the 66th minute. What a miss! Courtois got a touch on the ball, but it doesn’t change the fact that if Rashford wants to be considered as a starter, he must not miss those types of opportunities.Roberto Martinez decided to give the recently recovered Vincent Kompany a run, taking off Vermaelen to make place for the experienced center back. The next swap was Danny Welbeck for Trent Alexander-Arnold, signalling a wish to tie the game. Although, based on the play, that wish was really weak. On the other hand, why would England try to earn a draw? Losing this match meant a meeting with Colombia (possibly without James Rodriguez) in the Round of 16 and then (potentially) either Switzerland or Sweden in the quarter-finals. It also meant avoiding Brazil, as well as the other superpowers in the top part of the draw. Pickford saved Dries Mertens’ effort in the 89th minute. Marouane Fellaini missed in the 92nd minute and that was it. Belgium won for the third time in three matches, finished first with 9 points and will meet Japan next.last_img read more
