The fact that builders can build "show house" and neglect such essential performance details is a shame. It shouldn't surprise me after being in the industry for 17 years, but it is discouraging that we have not progressed. I am recommending ventilation now before talking about air sealing so that customers can get it in their minds and vocabularies and try to normalize ventilation, make up air, etc. I am becoming more concerned with the health of homes than the "performance". Nice video, I do enjoy the trade show tours, and new product highlights. I would enjoy a semi-regular new product video showing things that are on the market and ready to implement.
Great video and I loved the expressions on the faces of the manufacturer reps when you strolled up with your test equipment! Great analysis of the 7000 sq ft monstrosity of a home. It goes to show that even the high-end builders aren’t doing all the math.
AeroBarrier rep confirming my comment in your other video regarding the claimed airtightness of that large show home - nice!!! Basically, 0.3 ACH50 is not happening with all those sliding glass walls etc, and my bet is 5X the claimed air leakage with all the windows and doors untaped after the test. 😊
Really like the entire break down of the house and getting an understanding of cfm. I would love to see more examples of this information. This way we can understand the better ways to design our homes. Also, are you saying we should not be using normal bath fans in bathrooms anymore? We should be using erv fans for our bathrooms?

I agree, the format of you reviewing a house is easy to watch and conveys a lot of info at the same time. Maybe consider making more of these, could help with the algorithm too, if you find popular home tours and then review them in this way as a 'response video'.
Great video. At 42:50 I think they are referring to the brand of windows used in the home - not the direction...right? Also for a luxury home windows with a U factor of 0.34 seems pretty low.
The center stove exhaust fans only work well (in my experience) if you put a lid on the pan/pot and slightly move the lid towards the vent so it draws air over the food and then out. That works really well but everything else sucks.
I have the same ExTech particle measurement device and the pm10 always shows 0 or 1 values but never more. I was wondering if you could share how you measure pm10 using this device. Thank you and keep the enlightenment going!
I love the idea of the recirculating shower (RainStick) since we are building and will be on septic - anything that reduces the amount of water entering the system will improve it's performance. However, one thing I can't get a straight answer about from the company is whether or not the UV light that this unit uses operates at a wavelength that is likely to generate significant amounts of ozone. And, if ozone is being made, does having it in the shower, directly below the ERV exhaust mean that there will be minimal risk of exposure to further chemical reactions from the ozone and whatever else might be in the bathroom due to venting? Any thoughts?
I don't want a recirculating shower, any more than I want a toilet that is recirculating water on top of me. Because everyone pees in the shower, right? Hopefully you probably don't poop in the shower, but who knows what happens if you're sick or you just can't make it out of the shower in time.
The aerobarrier ACH50 number being lower is because bath fans, dryer vents, etc are sealed. So it's basically cheating. It's sealed so the aerobarrier doesn't seal where it shouldn't.
Great video. Sorry you run into buttheads that ask you to leave when you’re just asking questions and wanting straight forward answers. Not in the market right now for HVAC but when I do I’ll avoid that company. Keep up the great work and way to be the bigger man and take one on the chin. Grace and Peace Slick
If you wanted to use a whole house fan in a more efficient and safe manner, you could get an economizer controller and set it up for differential enthalpy control. That way, it would only run when the outside air enthalpy is lower than the inside air enthalpy. They arnet that expensive, about $700 at Supply House I think.
@52:45 -- you talk about the glass doors in the master bedroom and the interior curtain track, and how this would be better served by exterior screens or shades. I'm curious -- do you have any recommendations for brands or types of exterior shades or screens? Because the only thing I know about in this space is German-style Rolladen, and I don't think those are going to work here. So, I wonder -- what would work here?
Sorry, no advice here- I know it’s beyond the budget of a large part of my client base, but that the ones who want it seem to find what thry’re looking for without my help.
I dont believe the numbers on that house. .35 ach with windows that have a u factor of u .34.... Maybe with the tape left on during aero barrier it was .35 ach 50.
The Pella window install thing looks to be designed by a high school mechanical engineering class. After their rotten window lawsuit they need to up their game.
You have a toxin-exuding gas stove in your kitchen! Gas stoves leak 75% of the toxic gasses when they are turned off and the vent hood fan isn't on. Don't try to con people into ugly ersatz fireplaces, just specify a Wood Burning Russian Masonry Heater. Russian stoves are the only wood burning fireplaces allowed to be built in the (highly regulated) state of California. Because they have glass fire doors (like wood stoves), room air never mingles with combustion gasses or particles from the fire. There's no backdrafting. All combustion air is drawn from outdoors. Smoke, gasses, and particles from the fire are not directed to a vertical flue, but circulate around and behind the firebox and take a long serpentine route to the top of the chimney. This essentially turns the chimney surround and chimney breast into a clean exhaust system while extracting the maximum amount of heat from the fire. [Whoopee! I get to play Borg Queen] Your efforts to convince people in cold climates that they don't want a real fireplace are futile. Investigate Russian wood burning stoves.
Could you please buy better video equipment, most people do not need a close up of their faces or yours. Your videos would be easier to watch if you could zoom out.

Best informative video on many products and innovations at IBS 2024. Great video Corbett.
Hey thanks Joel buddy

Love the snappy clips on this! Great work!!
Thank you
One of the best IBS 2024 videos I have seen so far.
HELL YEAH thanks man

When it comes to smoke puffers, we use Cirrus brand. Uses cartridges for smoke generation (NO messy liquids). Has USB port for charging.
Us too, I think they're made for hunting applications due to the GPS abilities but it works great as an air leakage vape.
Awesome video Corbett. Have you ever used or recommended the AeroSeal product?

Super job! I need to get my notebook out and watch all of your applicable vids!!!

PM10 falls out of the air fast- shouldn’t be much unless it’s terrible AQ
@@HomePerformance well noted. Thank you!

Haha thanks Slick!
I can think of a scenario when you would want to run your ERV on recirculation mode--forest fires.
A lot of good stuff here, (im)patiently waiting for the release of that new Retotec single channel manometer
Ditto
Would love to hear your opinion on the CERV2 ventilation system.
Great video. I definitely learned watching this.
Glad to hear it!

I would wonder how many people ever use the full maximum capacity of their range
While you’re at it, also wonder how many ever turn on the fan if they haven’t burned anything
The most feared person at IBS 😂
Haha shiiiii#

20:01 would love to see that video haha!
Yup, those fake flames are indeed a much better idea for IAQ and they're starting to look somewhat realistic! Nice!
Excellent video. Thank you !!!
Glad if it helps
Great info as always...
Glad you enjoyed it
Corbett what do yout think about fresh air uvs APCO X units?
Solid no from me Frankie
I dont believe the numbers on that house. .35 ach with windows that have a u factor of u .34.... Maybe with the tape left on during aero barrier it was .35 ach 50.
Mmmmmmmmmm

Pretty sure he has an inductive range, not gas.
Thanks for noticing Mac
I'm team video flames 😂
Can a uvc light nuke bedbugs?
I’m sure it’s been tried, and no way it works- they’re not microbes, you’d just give them a sunburn and make your environment more toxic in general.

Thanks for noticing the important stuff Tony. I will keep doing whatever is easiest and fastest for this free channel that’s totally free.
I thought the videography was great.
Awesome video! You are a real pro!
