- Take my Ventilation Training and learn all that I know about this complex topic: buildingperfor...
Thanks to Broan, Dwyer, Defender, Mason-Grant Consulting, and Lawrence Berkeley Nat'l Lab, the #TinyLab is the highest performance tiny house on wheels ever built. The air quality and moisture control is finely tuned, and in this video watch the testing of each subsystem of the mechanical ventilation system as a whole. The ventilating equipment is all Broan (130APE kitchen exhaust, ERV70TE ventilator), the test equipment is Dwyer Instruments and Retrotec, and the CO detector is a Defender.
VERY solid video !
thank you for this.
Very well done Corbett. I can't wait to see you in Cincy. I'll be putting some things together soon.
+David Horton see you next week brother!
+David Horton excited to reconnect, brother!
Great information, diction, and delivery. Did it without massive (if any) editing. Sincere congrats :)
Thanks brother!
in deed. I was going to comment along those lines, but you’ve nailed it.. !
🙌🏽
Shower room air slots would be better near ground level
Not every day you get tot give a sincere shoutout to Berkeley Nat'l Lab :)
+Zachary Young enjoyed every minute
Awesomeness!
Thx +Stephen!
Look in to Tamarack cape damper. It is a in line type.
+Michael will do buddy
Thank you for the video!
Thanks for following Fellipe
Corbett, great video. Very informative. Which of the Dwyer kits did you buy?
Thanks Andrew! This was the IAQTP kit, don’t know whether it’s still available.
The ERV70TE has been replaced with the B130E65RT but the B160E65RS can also adjust the airstream all the way down to 35CFM. The price difference is about $160 USD. It has 6" ducts instead of 5". Decisions, decisions.
Great talk! What made you choose the Broan ERV over the Panasonic ERV? I saw Your video on the Panasonic ERV and it seemed like it was a great solution for your Tiny Lab.
+Genevieve Trainor it didn't have as much variability or customization (even with a new hole in it), and didn't address kitchen exhaust at all. The Broan system controls all of those factors easily.
Thanks for the reply! Is the Broan ERV circulating air on a 24/7 basis? I was also wondering if you have a schematic/illustration anywhere of how your tiny lab ventilation system is laid out. Cheers!
+Genevieve Trainor only for attendees of my Saturday workshop in the tour cities- you should join us!
I would love to, but alas I am located in Seattle, Washington.
Wow! Are you a NASA engineer? Because your tiny house is so high tech I thought it was a spaceship :) Very impressive.
Wow, thank YOU. Trained as a piano player, nice to meet you.
@@HomePerformance Totally deserved. Using both hands correctly on a piano would be a challenge for me hahaha. Nice to meet you too
Well that explains the Moonlight Sonata on the bedroom above garage video.
Haha glad people are still seeing that one
Great channel man!!well since you know your stuff Im going to ask you a question if you dont mind.
I want to do a darkroom retreat at mt own house,obiously no light should be passing thru so how could I achieve perfect ventilation? and HRV system?but the noisy engine or system should be away from this room so I dont listen to it while ...should I drill a hole in the wall like with an air conditioner?Im aware that air conditioners dont pump in fresh air from outdoor so a/c isnt an option I guess?If you have any ideaof whats best tell me.
thanks in advance
+lighthouse94 thanks for the compliment, and yes, an ERV is a great ventilation solution. If you'd like any consulting on your project specifics, we do that for people all over!
Great video. I wish my home had better ventilation. I had new bathroom fans installed (Panasonic). They work great -- except in the winter. The flapper on the outside of the wall that prevents air and critters getting in, freezes up each winter -- when I need the exhaust fan the most. I have vinyl siding, and the outside vent matches the siding. Is this a common problem? Do you have any solutions?
+59seank have not heard that one, Sean, but maybe they should be used more often? Timers can extend the runtime for an extra 20 min after use, so the last air that hits the flap before closing isn't totally steamy?
Thanks for responding. I'll give that a try!
It seems like you lose a lot of precious warmth when exhausting your cooking air (I've read that you only use 23% of the heat from the stove to heat your food and the rest is lost). What do you think about integrating a heat recovery system into the exhaust hood or would this not work due to the greasiness of the cooking air? Would you then have to filter it first and then be able to recover the heat?
Grease and velocity would make it impractical, sadly. The heat recovery core needs to have the air hang out for more than just a quick zoom through.
Maintaining comfort with humid hot air demands more energy consumption than heating fresh, less humid air ( once heated back to room temp relative humidity goes down)
Hey there. I'm building a shed house and just now finding out about the importance of ventilation. I'm trying to figure out if I want an ERV system or just live with pressure problems caused by evacuating moisture zones directly outside (bathroom&kitchen). Is the pressure a really big deal? Wouldn't it be a non issue if I just opened a window every now and then?
Exhaust pressure will pull outdoor air into hidden cavities in walls and ceilings and floors. May cause condensation and mildew and mold in humid weather.
@@HomePerformance
....but if you open the window?
Then no pressure, but you quickly move your home’s temperature, moisture, and contaminant levels toward outdoor levels. Expansion/contraction of wood, drywall, etc, fluctuations in microbiology and chemistry, etc etc. Watch this:

Would that 8” damper/hole in the wall let in all the unwanted contaminants that we are trying to exhaust?
@_FullSpeedAhead_ yes, but they go right out again
what model of bath fan is in the shower? It is so small!
That's not a bath fan- a bath fan in this house would be a disaster for pressure reasons. What you see is the exhaust port for the Broan ERV.
I have a 14*48 unfinished Gambrel roof on my tiny home. I am curious about how I can vent the attic that is to be built??? Any suggestions? I see you also do consulting.
Hi Hedgehog- there are several ways, but it would have to be detailed specifically to your home. I’d be happy to help you figure out the best way if you want to hop on a consulting call.

Very good video. Interesting. I don't want or need an HRV or ERV system. But I would like to use that dampner controlled intake vent instead of wall trickle vents my builder is suggesting. It might be my solution. What is the name of the unit that controls the dampener? Thanks!
I believe that’s the Broan make up air damper (or makeup air unit - MAU). He mentioned it in another video but can’t remember specifically. Hope that helps! :)
Very good video. What size of duct did you use and what material?
This one shoots straight out the back, only 5” long rigid metal. 3 1/2” x 10” I believe.
Does the incoming air get filtered?
+Will the ERV yes. The kitchen intake has a bug screen, but otherwise no. No need, since it's turning around and going right back outside thru the exhaust hood.
Why do you have your hrv/erv unit outside of your conditioned space? even with the minimal insulation around your ducts, there's still going to be a big affect on your heating and cooling due to the large deltas in temps
We track the temps, Derek, it’s not a problem. And as for the location, there is no other place to install it. It’s a tiny house on wheels.
@@HomePerformance you could've made that space part of your conditioned envelope during your planning...
Why would I want that? There’s a propane water heater and solar batteries out there. No need.
@@HomePerformance you could vent both items... The need is to reduce the delta between the outside temps and your heating and cooling appliances. It's a passive house standard to have your ERV in an insulated, conditioned space. It's a very simple concept
I'm a little confused about the beginning test you did with the kitchen vent. You said that you turned on the vent and you couldn't hear anything, does that mean it was just on low? Then you turned the fan on and I could hear it and you showed the high pressure and said this is what most people do or buy, are you saying that you only need the fan on low and never on high, or do you have it running on low 24/7? Then you continued to the smoke test but it was unclear if you had the vent on low still or off.
Just trying to clear up what you are trying to show and what it proves! Also, does that kitchen exhaust connect to your shower vent, because you said that was the only place where air was pulled out of the house.
Thanks for making such informative videos!
+The Road Abode only on low when we use it, because we have proof that low speed does the job. Not running except when cooking, and not connected to the ERV. Thanks for watching!
Home Performance Ah! thank you for clearing that up, thanks again for the detailed information!
+The Road Abode you're so welcome!
