Video

I thought this video would explain how you can have "breathability" to stop the buildup of CO2 in an airtight home. It seems to be more about moisture (important, but not the same thing). How can you justify creating airtight homes that just build up CO2? Is the only way around to install expensive air filtration systems?

Thanks for these excellent videos! After seeing so many north American and UK videos lately covering energy efficient homes, it's great to see many of the same ideas discussed in an Australian context. I do have one question: because I have no experience or knowledge of building - and I'm really not a home handyman type - how can I be sure when I'm talking to a building or renovation provider that what they are offering meets the current best practice standards, and that their knowledge is up to date? I've had a bad experience with a "cowboy" builder in the past, and I would genuinely like to know if there's some kind of certification or verifiable qualification I can use to check whether my builder can meet this best practice. Sorry if this is an obvious question! I'm genuinely quite confused by the amount of information I need to hold in my head when discussing these topics with a builder.

Seeing examples like this of poor quality rental homes (and this far from the worst example!) makes me quite furious at the state of Australia's rental market. Yes, been there, queue of people looking at the property with maybe 10-15 minutes max to "inspect" it. No option to have things tested. No guarantee that the heating and cooling systems that appear to be in place will even work. And the law just let landlords get away with it. Just imagine if there were enforceable standards on landlords before a property could be leased? And if property managers had a duty to verify the quality of the housing stock?

what kind of worker should i hire to install a vented hood? i need the hood to be vented through a double glazed window in kitchen. so i think I'll need some kind of glass worker. but i don't know what qualification worker i should look for?

It's all about using white since white has the highest Albedo effect across the color spectrum. Have applied this principle on our own roof 😊

This video is epic!

Why did you go with open foam sub floor spray insulation over closed foam?

Is this bloke ok?

What about using the shiny metal roof with no paint ?

You ripper tape 😂i love it

You can buy this tape here. tighthouse.com.au/products/proctorpassive-yourippa-silver-tape?_pos=2&_sid=382887062&_ss=r

Yo is there much difference between a 2.5 and and 2.7 wall insulation batt

may we know which brand & model they use for rangehood? Do they use a recirculating hood, or do they vent outside? Any make-up air?

Love the Amiga computers...reminds me of my childhood!!

Learnt alot from this video, thank you so much!

3:39 is my bedroom window. Single glazing, 1950s brick house. I rarely have the blind up due to the room's position in relation to the street but, if I leave it too long, mould forms quickly. Is there anyway to stop/reduce the amount of moisture produced at these junctures during winter or am I stuck doing a daily wiping/drying of the window (or stop breathing and heating up the room)?

Feels like this is a very meaningful job helping people build a more comfortable place where they call home! Well done🎉 love it so much!

But now its down to 15 how does that actually feel...is it bearable, good etc

Where can we purchase the draft stoppers for the fans and do tgey need an electrician to install them?

Great video. I gotta get onto this. My original plan was to liquid nails some R4 polyester ceiling insulation i have but im guessing the xps is a better option. What thickness is the xps foam. Also is it worth putting the r4 polyester over the top of the entire hole after adhering the xps the the lid in the roof space?

My evaporative cooling is on its last legs and I will be replacing it with a couple of reverse cycle split systems instead. Until I can have the old evap cooling removed I'll be sealing the vents as demonstrated. I've used the contact method before but the insulation bag is a great idea I'll put in place too now. Last year I replaced the windows with triple and double glazing and the improvement in comfort is amazing. Gas bill for heating down 33%. Shows how low performance builder's spec (Aust. 1990s) brick veneer homes are, but can be improved. Landlords should not be allowed to refuse a tenant from making simple reversible improvements to their home that will improve the comfort and reduce their energy bills.

👉Gray and silver color are the best, next is white 👈

Who can i call to install insulation properly in melbourne?

How would a renter go about testing for airtightness and finding ways to improve the comfort of their rental property? How would a renter use the products listed in the video? Is it something they can install themselves? How about solutions for windows in a rental property?

My rental has one of the split system compressors under the house. Is this pulling in dirty air?

And there’s absolutely no reason for a homeowner not to do this stuff, but permanently and correctly fix these issues, for health, comfort and savings. Don’t wait guys.

Good informative video. Thanks

Great video for renters.

Take a shot every time he talks from a different location.

this guy changed my knowledge about what I know for Windows, very talented Thank you!

What a great segment with your professor. It's really difficult to know which vendor I can go through locally who will understand enough about the right kinds of glass and isn't just going to steer me to whatever gives the greatest margins... it's really quite frustrating. I moved into an older house last year and we are slowly improving it. Since it was an architects house for him and his wife, it is very well built and insulated... but the windows are awful, and waves of cold roll off them, even with heavy curtains. Trying to find that sweet spot in price:performance is really difficult. Do you have a video on being able to measure what gains you might expect out of choosing performance glass? Trying to figure out if there is some equipment I can hire to take a bunch of readings myself to understand where my house is at, rather than hiring a person which is often substantially more expensive.

You missed the question entirely.

Thank you. Hopefully you’ve cracked the code for this. I think back to the spray foam craze 30 years ago and hope we are smarter now about moisture

Is there any solution for an IXL heat lamp & exhaust vent. I have one but it's too big for the draft stopper

yebbit emma chisit ?

Great video, but what's with the awful background music? I had to stop the vide halfway as I could not focus on what's being said due to the music.

It doesn't matter, as soon as the seal breaks and the gas escapes the condensation moves in and the window becomes foggy... it always happens.

Triple pane windows are common in Europe and are becoming more common else where. Single pane windows were common in the 1930s. Double pane windows became more common in the 1950s. Triple pane windows are now more common in the 2000s. Energy efficiency matters. Wasting energy wastes money. There is a climate crisis. Triple pane windows need to become the standard.

Yeah that’s terrible. So many issues. Although I’d say the indoor AC unit probably had filters mounted on it as well (hopefully)

Thanks for sharing. I'll never forget how to explain Low-e coatings again! :D

Amazing video. Best advise is to take samples and spend a good week or two with them. We did this for the tinting we chose for our house. We naturally felt inclined towards using the light blue tint. it makes the outside colours look way more natural than greenish, brownish, greyish and even yellowish tinting options we got provided. Most important is realizing in cloudy days the non blue tinting performs very bad. The downside of the tinting with a colour is that this is a reflective film so at night when lights are on the house becomes a mirror. But this is a trade off like anything in life so we are really happy with the Choice. go Blue!

Good discussion about the coatings and tinting of the glass. Could have also discussed the affect of thickness of the glass and the spacing in igu. Finally a discussion on the importance of the frame to the overall performance of the window. A lot of Australian manufacturers still use aluminium frames that negates any benefits from double glazing.

You said forget cooling your home with one or two splits but then you recommended getting one or two quality systems for your home at the 410 mark. Huh?

Beautiful LECTIO MAGISTRATES was explained by a great professor whom I personally know.

Thank you, great video. Can you give an example of how much heat low e glass can save (in a cold climate) vs the other types of heat loss through the glass. Ie - what percentage of heat loss is due to emissivity? I'm looking at dbl glazing (in nz) and not sure if low e is worth the expense. Thanks again, Simon

Great video. A bit on the longer side but worth every minute. I learned a lot. Thank you

A nice primer/crash course on this important topic. The professor was trying very hard not to use technical terms, but it’s a scientific topic.. there’s no way around it. By the way, is there a website to go to for more details? Thanks.

How much?

Does paint sheen matter? I've heard that high-gloss reflects more sun.

Ceramic paint may also help with the noise and heat transfer.
