Basically, the idea is to have as much exposed mass in a monolithic wall (or floor) construction as possible so the nine inch blocks that Percy mentions are a good starting point, so long as they are dense and not lightweight. The hollow blocks filled with concrete and reinforced would also provide a dense monolithic structure but leaving them hollow would not. The thicker the monolithic wall, the better its capacity for absorbing heat. Make sure the inside face is plastered, rather than using plasterboard on dabs or battens though, as use of boards would create a cavity and prevent the mass of the wall being exposed. Ventilation also has a big part to play though - both passive and mechanical if necessary - especially at night when the heat of the day that has been stored in the structure is released.
However, be careful not to double up on construction - why build a concrete frame if using solid nine inch dense concrete blocks as infill? The blocks could be used as loadbearing elements in their own right, unlike a single skin of the Thai clay bricks.
Apart from the wealth of internet information, there are plenty of books on the subject. For an appraisal of some of the basics mainly from a Northern hemisphere perspective, try Ecohouse 2:

At a less technical and more academic level, there is also Amos Rapoports's thesis 'House form and Culture', which identifies cultural, rather than environmental imperatives as the real drivers behind the forms and even the technology used in traditional building. Hence the hot houses of Thailand, I guess!
One more word on the Thai use of bricks then. Laterite and clay bricks and blocks have been used in Thailand for centuries. Go to any of the historical parks containing ruined ancient structures - Sukhotai, Ayuthaya, Kamphaeng Phet, Sri Satchanalai etc. and you will see the centuries old ruins of temples, palaces, chedis and statuary all constructed of bricks and blocks. Bricks are not a new concept for Thai builders but historically, bricks have always been stuccoed.johnrxx99 wrote:Red thai brick sound spurious to me.Traditionally the Thai use teak and open volumes of space etc. Brick is recent is it not!
