Just read an article mentionning a "hollow tiles" system that you install in your house had won a price. It was in french, good luck with google



But anyways, the best way to lower the temperature inside is to provide yourselves with SHADOW !
- green roof / insulation
- overhanging roof with air flow beneath
- shutters (mobile/fixed)
- trees...

Now it's even possible to simulate in 3D the exact shadow you receive from your environment (trees, houses, buildings...), for the location where you live, for everyday of the year.

Then you know exactly which part of the house to protect from direct sunshine, mostly around noon time for the hottest months. You can also calculate the angle of the sun rays you want to block when it's hot, and which angle to let go through when it's cold. I'm doing this for a villa in Chiang Rai and somebody who would like to use the sun to his advantage =D


That shadow calculation helps other systems such as the cool-air column (water/air), which termites and ants have been successfully using for millennia to set their hatcheries temperature to the exact degree they need.



There's a lot to be done in a house, systems acting in coroboration are more efficient than just one alone (even the latest 'super top ultra thing'). Better to think it up before building !

DrAndy

all true

when I designed my house I made sure which direction the sun came from.

Windows are not facing S or SW, in general

The walls are QCON, good insulation

There will be lots of shade to live in

watterinja

An excellent suggestion...

Airportwo

Using swimming pool water? My pool water is 36c at the moment!.........
Drops to 24 ish in the cool season.........

VocalNeal

Sounds like you need some shade or A small cooling tower? But it would obviously use energy to run the fan. I have seen some local built ones that have no fan but I don't have any knowledge of how effective they are. I prefer to swim in water at 27, I don't like cold water.

36 is still cooler than 40 and that 4 degrees with air delivery can feel quite a bit cooler.. JFYI I am responding to the idea of using the cool air byproduct for cooling the house.

benlovesnuk

here you go this American agrees with German thinking, that's led to quite explosive situations in the past, i thought i might add it for my worthless penny of thoughts

I agree with that link.
I had a cabin in cold country, but it would also get damn hot in summer days up where the air is thin and the sun came up at 0430 and set at 2130. in summer and in winter it came up at 1000 and set at 1430.
Walls were 7/16 Sheetrock,4 inches of Fiberglass blanket, 6 inches of wood, 2 inches of rigid at 15 Rs to the inch, and cedar ship lap siding.
The roof was Sheetrock, 4 inch FG blanket,1/2 inch plywood sheeting, 12 inches of rigid foam insulation and the aluminum roofing, in all 60 Rs of insulation and the snow stayed on the roof all winter. and all windows were triple glazed.

Did you know the average male is 6 inches long, and the average female is 8 inches deep? So in New York City alone there is over 3 miles of unused pussy!

Double glazed units cost an arm and a leg. Can you imagine the cost of triple glazed units would be, plus the aggro in sourcing them>

DrAndy

They don't have to be special glass or gas filled, unless you want the optimum

you can make sure that your window frames have the rebates to fit the three glass panes correctly, then all the extra cost is just the two glass panes

one of the panes can be low emissivity glass (like K glass) if you have the arm and leg

There is a shop in sandpoint that makes them and the cost was more than I wanted to pay, I do remember that.
But when I acquired the cabin and 5 acres the end facing the creek, actually the front as the drive and parking were at the rear, was unfinished and it was sealed from above the kitchen/dining room windows and door out onto the deck with a heavy opaque plastic material, but was thermally OK but the noise level was terrible during breakup and spring water flows, it sounded like living in a bowling alley with the rocks bouncing along and banging together.
But I measured and made a plan for the windows I needed to finish the front and when it was done, it was very pretty, almost all glass with just the timbers and window framing, even the door was a thermal pane glass, and the next winter it was warmer in the house with a third the wood used, -40F and only used 1 cord of wood to heat it and during breakup, it was quiet in the house, and I got to see it too.
I was setting out on the deck in the sun reading, and could hear a train rumbling sound, well we were about 20 miles thru the forest and over mountains to the train tracks, so was strange, but the sound got louder and then it sounded up canyon, not down,
there was a fork in the creek out in the canyon in front of the house and the creek ran in front about 15 feet from where I was setting and also a branch ran around on the other side of a wooded island type piece of lane in front of me and went around to my right and came almost straight back to where I was setting and them turned at my property line and went down canyon.
So I was setting right in the middle of this action, I notice the water rise up over the ice and snow in front of me and was kind of muddy brown color, then up the canyon on the other side of that forested Island here came the breakup, Ice chunks and trees and water and all kinds of shit was coming roaring down stream, rolling and bucking and whole trees it had torn out and huge chunks of ice and it was 50 or more feet high and going 50 miles an hour and such noise as I have never heard before, around the bend and straight at me and then turned again and down stream it went, lasted for a good 30 minutes before is slowed down and shit quit coming down stream,, I never will forget that day.

For sure, you can have wooden ones made, but I was thinking about aluminium or uPVC units.

DrAndy

wooden ones are much better, and look better too

PVC may be Ok; are they sun-proof?

watterinja

Is there a reason why traditional Thai houses are built up off the ground - on stilts?

DrAndy

yes

they are cooler, cleaner, you get less pests coming in, and you can keep the pigs under

maybe helps during the wet season too

blackgang

The ones we used were PVC, aluminim is not to good when it gets really cold as they tend to sweat and ice up.

Marmite the Dog

The ones used over here are supposed to be.

DrAndy

prob not then

wood every time

DrAndy

sorry, that was not clear DF

climbs=climates Ok

but the phrases are a bit mixed without punctuation

please repeat with more info

blackgang

They are, UV resistant plastic is nothing new.

Yes and then again time after time,,shrink, swell, Crack and peel,, and damn fine termite food.
