Note the if you hose them down bit marmers, dark colors absorb and retain heat, better off with a nice light color a nice pale pink perhapsOriginally Posted by aging one
These are not normal bricks DD. They're like smooth engineering bricks. Do you know what they are? You should find out, 'cos that's what I want.Originally Posted by dirtydog
I would guess that the bricks are the more usual clay type that absorb water. If they are given a good dousing it will take some time for the water to evaporate. Engineering bricks tend to be pretty impervious to water.
I have a wine cooler (very posh in the Dougal household) here that works on the same principle.
Lord, deliver us from e-mail.
Thats probably a good idea aswell, otherwise it would destroy the wallpaperOriginally Posted by Dougal
I'm sure my builder knows exactly what they are, but he's JUST BEING AN ANNOYING KNUT!!!Originally Posted by Dougal
Get some pics of the bricks and show that to your builder.
In purely thermodynamic terms, some of the water evaporates, and this removes heat from the surroundings. Much like boiling water, which basically is rapid evaporation, and requires energy (electricity).Originally Posted by hillbilly
The opposite effect can be observed when moisture in the air condenses on your beer bottle. The condensation gives off heat, which heats up your drink. In fact, a cold drink will heat up quicker in a moist environment than in a dry environment for that very reason.
Getting back to evaporation, the water spray coolers one sees around open air restaurants and bar areas basically atomizes the water (very small droplets), giving it a huge surface area, and thus speeds evaporation. This evaporation takes heat from the air, and voila - cold air.
Any error in tact, fact or spelling is purely due to transmissional errors...
They are great for dry countries but here I think it is too humid for them and the evaporation process takes too long, they just seem to make you feel even more sticky.Originally Posted by Whiteshiva
I agree they work better in dry climates, but they do work here as well. Humidity here is normally around 70-80%, so there' still room for some more water in the airOriginally Posted by dirtydog
Oddly the production of most electricity involves boling large ammounts of water to drive the turbines, which drive the generaters, the electricity then passes down long lenghts of electric string to peoples houses for use in boiling water at a local level.....ironic realyOriginally Posted by Whiteshiva
Yeah, I agree - not very efficient, but the best we have at the moment.Originally Posted by RandomChances
Find a new way of converting heat to electricity, patent it, and you will be richer than Bill Gates in no time.
When building a slightly taller roof with light coloured surface should help. Vents at the soffits and eaves should help. Air should naturally circulate in through the soffit vents and out through the eave vents. Unless water is free spraying it on the roof may turn out to be just as expensive as AC.
In a climate like Thailand a floating roof over the structure might make sense, then the ceiling needs to be "critter tight" though as it would act as a sort of second roof.
Feck, for all this trouble, why not just move to Sweden? It's pretty cool there.
I'm moving into an extra large freezer fit with a toilet, a bed and computer desk. I'll build my house around it.
The main reason I bought my brand of aircon is that it removes the humidity from the air. I have a hard time cooling down in a humid climate.
Here is a house being built out of superblock.
So apart from isolation, what's the advantages of these bricks over the red one ? are the walls more resistant ?
Quicker to lay, easy to cut, ie with a woodsaw, plus they are all the same size and shape
What about strength DD? You for sure couldnt use them in SF, Tokyo, or Taipei because of earthquakes it would seem.
Superblocks are slightly stronger, check their web site for specifications.

About being same size and shape, yes they are until the brick layer has ruined it all.. Just take a look at the picture.. They could as well have been deformed already in the factory instead of at the building site.

I am amazed at what Thais will do to make something that is already straight, not straight. I was teaching that guy how to not recut a piece of woods if the edge were already cut straight from the machine. He still couldn't get it.
Well their motto is "Why do it good today when you can patch over it tomorrow"..
As these blocks are not load bearing strengh is immaterial? I think, is that right DD or is my understanding of building "methology in Thai" wrong?Originally Posted by aging one
Cheers
Nope they are not loadbearing, still need to pour your beams and everything.
The cooling effect of water can be very good, it soaks into the bricks and slowly evaporates, thus cooling the area. Some bars use a fine mist spray to keep their customers cool.
spraying it on the roof though seems a bit wasteful, even if it does help a bit. Better insulation is the way to go, and some sort of venting system. Most traditional houses in Thailand use this method.
