The Ventilation Omission That Can Make You Sweat

first_imgThe sin of omissionIf the motorized damper isn’t there, the negative pressure from being connected to the heating and cooling system’s return ducts will cause more outdoor air to be pulled in through the ERV. (The same will happen for an HRV.) The result is that the house will be overventilated, especially during winter and summer when the heating and cooling system runs more often. If the system is right-sized, it will run more often than a typical over-sized system.[Editor’s note: The problem described by Allison Bailes only occurs with some brands of ERVs and HRVs — those that don’t include an integral motorized damper. Many ERVs and HRVs include a factory-installed motorized damper (located inside the unit). If you prefer to purchase and ERV or HRV with an integral motorized damper, contact the manufacturer before purchase to find out whether a damper is included.]Another case where this creates problems is when the home has a ducted minisplit system. Those air handlers run all the time, though they do ramp down to low speed when the thermostat setpoint is met. Still, we’ve seen a system like this that brought in excess ventilation air and made the house uncomfortably humid in summer.A standard forced-air heating and cooling system can cause problems, too. If the occupants set their fan to the on position, the system will pull in more outdoor air if there’s no motorized damper.Even if the ERV or HRV has its own dedicated duct system and is not connected to the heating and cooling ducts, you need to be able to close the hole when it’s not running. Otherwise, stack effect, wind, and other mechanical systems in the home can pull in outdoor air when it’s turned off.If you’re designing or installing ventilation systems, make sure you get to know this little device. It’s an essential component. The missing linkIf the ERV is designed to bring outdoor air into the house only 20 minutes per hour, there needs to be a way to close the hole to the outside for the other 40 minutes per hour. Such a device is the Turbo Thermo-Encabulator Max. RELATED ARTICLES Designing a Good Ventilation SystemWhat is the Deal with Ventilation Requirements?

You can follow him on Twitter at @EnergyVanguard.center_img Oh, wait. Sorry. That’s for something else. What you really need is a motorized zone-control damper, like the one shown below. Every HVAC supply house sells them. The motor is wired to the ERV controller so that it opens and closes when the ERV turns on and off. If you’re designing a ventilation system, first you have to determine how much outdoor air the house needs. You can use the ASHRAE 62.2 standard or the new BSC-01 standard for that task. Then you have to decide what type of ventilation system to use: positive pressure, negative pressure, or balanced. In many green homes, the balanced system is becoming a popular choice. I’ve seen some installations lately, though, that are missing a key componentThe balanced system shown in the photo to the right is one such case. It’s an energy recovery ventilator (ERV) that’s connected to the ducts for the home’s heating and cooling system. The duct with the fresh air from outside is connected to the return plenum of the forced-air heating and cooling system.If the system is designed to run continuously and factors in the negative pressure created by the duct system it’s attached to, this can work well. A typical ERV, though, can move 100 to 200 cubic feet per minute (cfm) of air. A typical house needs maybe 50 cfm (depending on the size of the house, the number of occupants, and which ventilation standard you go by). What many designers do is set the ERV to run intermittently, say 20 minutes out of each hour, to meet the ventilation needs of the house.last_img read more

Breaking another glass ceiling

first_imgWhen Laibi Oinam got in the front seat of a second-hand auto-rickshaw as a driver almost a decade ago, she received a lot of negative attention from people in her home state of Manipur in northeast India. But her life took a new turn in 2015 when her struggle to get passengers and earn her daily bread to support her ailing husband and young sons caught a filmmakers attention. Now in her 50s, Laibi has bought herself a new auto-rickshaw, her younger son is inching closer to his football dream and she enjoys respect in the same society that once looked down upon her for driving an auto and breaking another glass ceiling for women without really knowing it. Also Read – An income drop can harm brainLaibi says that she didn’t take up the job of an autodriver in 2011 to challenge stereotypes. Her husband’s deteriorating health and sons’ education demanded more money. What she earned by working in a brick kiln was insufficient. So, she collected money through chit fund and bought a second-hand auto. “I rented it out to others but we didn’t get much money out of it. Meanwhile my husband got unwell, so I decided to start driving,” Laibi said. Whether it is fighting for a cause or selling vegetables or handloom weaving, traditional male bastions, women in Manipur have always been in the forefront of society. But the same can’t be said about autodrivers. Also Read – Shallu Jindal honoured with Mahatma Award”When I started driving auto in 2011, I used to wear phanek (traditional wear of Manipuri women). Later on, I changed to pants as people often refused to take rides because of my gender and outfit,” said Laibi, who learnt how to drive on a Vespa. Since the sight of women autodrivers was not a common one in Manipur, it caught the attention of film director Meena Longjam. “I met her in 2012. It was an accidental encounter. There were many male autodrivers in the market and then there was this one woman waiting to get passengers in her auto. I had never thought that a woman could drive an auto in Manipur,” said the Madras Christian College alumnus. An article on Laibi piqued Meena’s interest. “Someone had written an article on her. Then I thought of talking to her. Also, I remember back in 2011, there was an economic blockade in Manipur for so many months that it crippled all of us. I thought of sending out a message to people through my film. “I wanted to show how despite all the problems in the state, a woman is working hard to support her family,” said the filmmaker. The documentary Autodriver is barely of 30 minutes but Meena gave about three years of her life to it. “While talking to her, I noticed that Laibi has big dreams for her children. Though one of her sons had to drop out of a Sainik school due to her financial condition, she still dreams big. She wants her elder son to become an IAS officer and younger son a footballer. “Her journey is very emotional. She does all the household chores and then heads out to earn money as an autodriver – a challenging job for a woman in Manipur,” she added. The emotional story connected with many. It even bagged the best social issue film in the non-feature category at the 63rd edition of National Film awards. “Now I am a known face. A lot of people have started supporting me. Even traffic police officials don’t bother me much. My younger son is studying in a football academy in Chandigarh. The elder one is almost done with his graduation. I earn around Rs 1,000 per day,” said Laibi. She also revealed that the amount is almost twice what she earned when she started out on her challenging journey.. So once her sons start earning, will she quit driving? About that, Laibi said, “I know how to make ‘phee’ (traditional Manipuri handloom long scarf) but I don’t enjoy doing it. I think I will drive my auto all my life. I like driving. It suits me.”last_img read more

Iowa coach Kirk Ferentz on Ohio State They pose a lot of

Iowa running back Mark Weisman (45) rushes down the field during a game agianst Minnesota at TCF Bank Stadium Sept. 28. Iowa won, 23-7.Credit: Courtesy of MCTThrough its first six games, Iowa (4-2, 1-1) is the only member of the 125-team Football Bowl Subdivision who has not allowed a rushing touchdown yet this season. Ohio State’s 11th ranked rushing attack plans to put the Hawkeyes’ streak to the test.The chance to be the first team to reach the end zone on the ground against Iowa this season is “definitely an incentive” for the Buckeye offense, redshirt-senior center Corey Linsley said.“Coaches don’t need to say too much. They just put a piece a paper on our desk and say, ‘They haven’t allowed a rushing touchdown,’ and we kind of get it,” Linsley said.Iowa has one of the nation’s best defenses, ranking ninth nationally in total defense with an average of 290 yards allowed per game.“They’re in the top 10 in America and our kids know that,” OSU coach Urban Meyer said of the Iowa defense. “We’re working really hard. They’re good. They’re really sound.”Linsley said the matchup with Iowa’s defensive line will be the toughest opposition the OSU offensive line has faced all season.“They’re physical, they’re tough, they’re big,” Linsley said. “In terms of toughness, in terms of things that we preach and the values that we take, hold to, that’s what they’re about as well on the defensive line.”Iowa coach Kirk Ferentz said he thinks the OSU offensive line will challenge the Hawkeye defense.“It’s going to be a tough matchup for us,” Ferentz said. “They look good. They’re big, tall, imposing guys. They look like an NFL line, and they (are) extremely well-coached.”Overall, Ferentz said OSU’s scoring offense, which ranks sixth in the FBS with an average of 46.8 points per game, is “extremely talented.”“Look at their offense, pick a position and try to find a weakness,” Ferentz said. “Good luck on that one.”The Hawkeyes are going to have to be prepared for numerous running threats from the OSU offense to keep their streak alive.Senior running back Carlos Hyde is expected to lead the Buckeyes’ rushing attack Saturday after rushing for 168 yards and three touchdowns against Northwestern Oct. 5.Additionally, senior running back Jordan Hall, who leads the Buckeyes with 69 rushing attempts, 427 rushing yards and eight touchdowns this season, is expected to be back on the field Saturday, Meyer said, after missing the game against Northwestern with a joint issue in his knee.“His first way of assisting the team will be on special teams and then he can certainly complement Carlos and be also involved in third downs,” Meyer said of Hall.As a passer, junior quarterback Braxton Miller has completed 49 of 75 passing attempts for 609 yards and six touchdowns with two interceptions this season. His ability to make plays passing the ball will make it tougher for the Hawkeyes to defend the run, Ferentz said.“They pose a lot of problems in a lot of different areas,” Ferentz said. “They can throw it very effectively … (Miller is) a great running threat, as is (Hyde) … It makes it tough to play defense. You can’t really tilt your team one way or the other.”Ferentz said he would like the game to be low-scoring but realizes other teams have been unsuccessful in keeping games that way against OSU.“I’m not a great fan of getting in shootouts any time,” Ferentz said. “I mean if we had a lopsided lead, that’d be OK, I wouldn’t mind that, but not many teams have done that to Ohio State in recent history. Trying to contain their offense, that’s going to be quite a challenge.”Linsley said it will be important for the OSU offense, who has outscored its opponents 126 to 28 in the first quarter this season, to control the tempo of the game from the beginning.“We’ve got to score right off the bat, and then after that, we got to manage the clock by running the football,” Linsley said.While OSU is trying to end Iowa’s six-game streak of not allowing a rushing touchdown, the Hawkeyes will be trying to end a streak that dates back to the start of the 2012 season. The Buckeyes have won all 18 of its games with Meyer as coach, and hold the nation’s longest winning streak.“They’re approaching 20 straight wins and you don’t do that by accident,” Ferentz said. “It takes more than just having good players … they’ve been very, very consistent. If you look at the rate they’re scoring points and they’re moving the football, that doesn’t happen by accident either.”Part of the challenge in Iowa’s effort to end OSU’s win streak will be the Buckeye defense, which ranks 15th nationally with an average of 326.2 yards allowed per game and 24th in the FBS with 19.2 points allowed per game.“We look across, we see a team that’s very, very talented,” Ferentz said. “That includes their defense. They got phenomenally gifted athletes on the back end, I think they’re playing well and certainly that’s the case with the guys up front too … it’s hard to find a weak spot on their football team.”Iowa’s rushing attack is led by junior Mark Weisman, who has rushed for 624 yards and three touchdowns on 126 attempts this season, and ranks 32nd nationally in yards per game. Weisman said that going against the Buckeye defense is going to be tough.“They have a great defensive line, great linebackers, good secondary,” Weisman said. “They’ve pretty much stopped every rushing attack this year, so it’s going to be a real tough challenge for us.”Another challenge OSU could present to Iowa is the environment of Ohio Stadium, where Saturday’s game is scheduled to be played at 3:30 p.m.“The ‘Shoe is just by nature, it’s one of the tighter, louder places I think in our conference,” Ferentz said. “We’ve been on the road a couple times this year … but we haven’t been in an environment like the one we’re going to be in Saturday and against an opponent like this, so that’s going to be another degree of difficulty.”If the Buckeyes extend their win streak to 19 games Saturday, they would tie the 2002-03 Buckeyes for the second-longest winning streak in school history. read more
