    Your second point is sure valid. Trying to avoid that with the PU-Foam backing, insulation materials on top of the ceiling and likely some sort of venting at the front.
    It's still design phase, so those problems need to be tackled when we start with the constructions drawing and of course with input from the architect.
    Might be as simple as an extractor fan that pulls the hot air into a pipe hidden in the 1m thick side walls. Then have that coming out at the back-side.

    If you can't get that natural airflow, that fan idea is a good back up.

    So far for TD Towers, we have only the air flow through the roof void and it is working. However, I put the heat reflective insulation directly under the tiles AND had the insulation over the first floor ceiling joists (like one would do to keep heat in, in the west!) so that double whammy is probably helping.

    It's a case of employing as many different methods as you can and hopefully the result will be a cool house interior.

    As we all know, heat is the enemy. Another area it can be influenced is how you design in the windows. Massive picture windows to look out can be great but they will let in a lot of sunlight, heating up the interior. Also, where you place those windows in relation to the suns trajectory throughout the day will be a factor. Lastly, a decent roof overhang can cut out at least some of the associated sunlight ingress issues.

    We went for 1m wide by 1.5m tall windows. single glazed, not double. All these windows open. for the days when you can make use of the air flow through. they are supplemented by working wooden shutters on the outside for security and light blocking as necessary. yes we are using them. The roof overhang is a generous 1.5m which does limit sunlight into the upper floor rooms. we are looking at the practicality of fitting something over the ground floor windows

    With windows on all 4 sides on the house we cannot avoid that trajectory but... we have it rising facing the exterior of zone 1 and setting facing zone 3. this means the main living rooms - kitchen, dining and living rooms do not have intense sun when they are being used. Sun comes up on the side of bed 1 and 2 but by the time it could be an issue we are already up. those AAC blocks definitely help with heat insulation

    The final heat influencer is...trees. What and where you plant them can shield the building walls from the suns rays. just make sure any root structure does not undermine your foundations. tree roots are pretty strong!

    Hope this is useful.

    Yes, there was a guy tried that ....was it here or CTH ? Bandersnatch was the name I think. A quick look back here and cannot find it. As I recall he later said the pipe was crushed by the weight of the earth, so you will need to look out for that

    My house was built 15 years ago and many of the materials available now were not available when I built so had to go with what was.
    Heat reduction was of course important. Roof, same as ThaiDupp's. Reflective sheet under roof tiles, insulation above ceiling and good airflow in attic. Works very well.
    Walls are red brick and with 1.2 meter eve on single story house actually do quite well in keeping wall and window heat radiation down.
    Plus now trees on east and west facing walls are now mature providing near 100% shade.
    Probably time to bump my build thread.

    I was thinking it might be nice to see pictures of members homes as new and pictures now. Could be very helpful for new builders as well as current for ideas and tricks used to keep the house cool.

    Our house is like yours in principle Norton. Red brick, reflective insulation, big air gap, ventilation throughout. We have lots of windows that are left open all the time and long eaves around the house.

    Great Pics Nort. Watching your house build come to completion and moving in is rewarding, even after 8 or so monks hang out throwing water and marking up the place with blessings. I was digging through some old pics. I will add a few as well. I had a house build thread like you but at the time all my pics were photobucket and that got dumped.

    I look forward to Schuimpge build.

    Yes indeed.. Bandersnatch tried it, documented on CTH.
    Surin Eco House. He had a pretty radical vision on building his house.

    Main protection for me will be the 1m side walls and double walls in the backside.
    Backside 'windows' will be glass blocks, which are very efficient at keeping heat out it seems.
    To protect the front glass doors / windows, the Pergola will help.
    Landscaping around the property, also to provide shading..sure. Can't wait to finally get a nice garden..

    Actually, the fence is not my creation, nor the land inside, encroached by somebody. And that picture is few years old, the fence made by composite "wood" looks no longer so nice, cracked and grown over... Therefore, from that side I no longer can have such a snapshot.

    However, from the front it is actual, just freshly painted inside outside...

    Well then, guess my current 1st and 2nd house are in order to show before and after:

    Pictures show the old houses in 2010, then construction starting.
    Some of the Electric Horror show I mentioned earlier and how it looks today.
    The balcony in-between the two houses was done on my design to make it look like all the other smaller houses in each block. You can see my neighbor (green house) balcony and see how it matches the style.

    These are the actual wires above the ceiling before renovation.
    It's now all rewired inside conduit and properly grounded.

    This is just after we bought the first house in 2010 (with the brown gate).
    1 year after the flooding we bought the unit on the left, Bank sale with a 40% discount.

    Klondyke, you certainly would win first prize if there was every a Home Makeover show in Thailand...lol..
    From that overgrown ruins to what it is now.. that's a winner right there...lol

    Actually, when we discovered it by chance - looking originally for something else - we fell in love with that, especially for the location, Far from the madding crowd...

    Backside added (laundry and bathroom. Visually separated from the main house by a glass block strip.
    Attachment 71313

    And to make sure sunlight on the front windows is minimal, a pergola added that will block most direct sunshine.
    There was me thinking I was being creative for designing my build in MS Excel. This is on another level.

    One of the things I have tried to do with my build during the design stage is close my eyes and sit inside every room and look for faults and items for improvement. But one really needs to focus the imagination.

    With an actual physical model you can see and feel so much more and anticipate the build to the extent that surprises and disappointments are almost entirely eliminated – you could even switch the lights out in the room and move a lamp over the model slowly to replicate the sun's diurnal motion to see the silhouettes that will be made on the floor every day in the future by the pergola slats.

    Inspiring stuff, buddy! I am looking forward to further entries in the story.

    Thanks for checking in Manc.

    I'm about to make payment to the architect to start working.
    Indeed, mimicking the sun is a nice thing to be able to do.
    With the pergola in front, I'm sure there's very little sunshine that will hit the glass directly and it makes for a nice play of shadows on the deck, especially when it gets filled up with plants, furniture etc.

    The model is back home again, now my youngest son's 'playhouse'..lol.
    What also made the model very useful was in helping to explain the wife what I wanted.
    Otherwise I'd end up (as you mentioned in your thread), with a brochure of standard and way too expensive designs...yikes.

    Hopefully the coming weeks I'll be getting some updates again.

    Cheers,
    Luc

So the coping just sits on top of the ridges, leaving gaps underneath. These looked like ideal animal and rain access points so I asked the builder if he could cut the coping so that it mated more neatly with the roof sheets. It turns out the roofer did this with hand shears and it wasn't a very tidy finish.
    Most roof tiles don't have this problem, they usually sell ridge tiles which fit snugly.
    I thought of this again yesterday when I found yet another of the roofer's offcuts where it has been hiding in the grass for a year and a half. Razor sharp bits of metal left all over the place. They were quite unhappy when I wouldn't let them bury all their waste materials in my garden, I made them load it all onto a large truck, but many small bits of tile and roof and concrete were left behind. This is the piece I found yesterday.

    Agree with using Bluescope color bond steel roofing, but want to make sure the solar reflectance (incoming) and thermal emittance (combined into solar reflective index) of your color choice is acceptable. We also found that some of 'first' choices were unavailable when we were ready to order, so we ended up with their silvery zincalume product which we have gotten used to.

    See page 9 of their brochure - https://www.nsbluescope.com/th/wp-co...ure-2020-1.pdf

    Hi Shutree, thanks for sharing this experience.

    We previously planned for CPAC Monier roof tiles, but are now giving serious thought to Colorbond / BlueScope. One issue I have seen mentioned in a few places is the issue of underlying foam falling off due to the metal expanding (from solar radiation during the day) and contracting (at night), with the adhesive underneath losing its adhesion.

    Did you have PU foam put underneath your metal sheets? What was the configuration? And how has it lasted? I would be interested to know other posters' experience with this.

    Colorbond / BlueScope

    I saw another thread on another forum where people were discussing the warranty on Colorbond / BlueScope. It appears that the metal sheets proper have a warranty with the manufacturer, but the underlying foam / insulation might be made by a different company, and a total different warranty – or none at all – may be offered for the foam, both by the manufacturer and fitter.

    Some home owners who opted for Colorbond with underlying foam insulation found out the hard way that the two are not the same package. In particular, if the installation is poorly done, then you might be sticking it back on / or buying new foam regularly.

    ////////////////

    Here is the link to the NS BlueScope brochure.

    Here are some of my translations…

    Seems a bit vague, and you'd need to read the T&Cs. Also, 5 years does not seem long for the colour.
