STRUCTURAL SLAB COOLING HISTORY FROM DESIGN PEOPLE ENGINEERS The use of radiant heating Gentle temperature conditioning system, and cooling is not new. The Romans, 2000 years ago, exchanges thermal energy to the space used under-floor radiant through convection & radiation. heating and thermal mass heat storage. In Turkey, stream water was run through channels in walls and floors to cool palaces in the warm summers. Even Akbar used it at Fatehpur Sikri. In the 1930s, architect Frank Lloyd Wright piped hot water through the floors of many of his buildings.
