7th Annual North American Passive House Conference

  
  
  

The Passive House standard strictest building energy standard in the world—and that standard is not met without UltimateAir’s RecoupAerator. Buildings that meet the Passive House checkmarks use 80 percent less energy than buildings that don’t, all while creating an environment of finer air quality.

UltimateAir’s own Jason Morosko attended The Passive House Conference in Denver last month. In addition to giving a lecture on the importance of earth air tubes, Morosko also had the opportunity to see ten current Passive Houses at various stages of construction. Sponsored by Passive House frontiersman Brian Fuentez, the tour showcased his current projects.

The 2012 event was the 7th annual North American Passive House conference. This year proved to have an increase in attendees, exhibitors, and presentations. The Passive House standard is growing rapidly in the United States. It truly is the standard of tomorrows building market. 

Passive House is the only standard within the US that requires mechanical ventilation like the RecoupAerator in its building code criteria with minimum performance standards.  “This is the best market for us,” said Morosko. “It’s the only building code that mandates our product.”

The best way to get started on your own Passive House is to find a Passive House consultant near you. Mososko serves as a consultant in Athens, Ohio. Morosko's personal work can be viewed here

For Morosko, the best part about owning a Passive House is that there is no utility bill. “That just doesn’t get hold,” he said. “It’s nine times more efficient than any standard construction.”

Energy Recovery Ventilation or Heat Recovery Ventilation

             There is quite a bit of debate out there as to where ERVs should be used and where HRVs should be used. For those of you who do not know, HRVs, like ERVs, are ventilation systems that transfer heat. However, unlike ERVs they do not transfer moisture.  We see a lot of maps claiming that ERVs should be used in the humid South, to reduce incoming moisture, while HRVs should be used in the colder North. However, these maps are inconsistent (for example, some suggest HRVs in the arid Southwest). Moreover they are wrong; ERVs can and should be used everywhere.
           While the "Bermuda Triangle" comparison might be something of a hyperbole, instances where an HRV would make more sense are few and far between. If you do not need to actively increase or decrease the humidity level inside your home at anytime during the year, then sure, an HRV would be an acceptable choice. At the same time, so would the ERV because you will not just be using the moisture transfer ability. But the claim that ERVs are bad outside of humid regions is just untrue. By transferring moisture as well as heat, they effectively assist moderate indoor humidity for optimal comfort and safety. Buildings in the dry Southwest that need humidity benefit from ERVs. Homes in the cold North would suffer similarly without retaining some humidity inside. The myth that HRVs are prefered in the North is based on a freezing problem that ERVs experienced twenty years ago. This problem has long since been fixed. However, some still use it as a misleading justification. The HRV industry survives on this misinformation.

Energy Recovery Ventilators are more efficient and practical. They are the ventilation system of choice for Passive Homes and commercial buildings. If you are making the investment for your health and your home, why would you go halfway? Maybe in a place where the laws of physics don't apply, like the Bermuda Triangle. Get lost HRVs.
