THE EXPERIMENTAL STUDY FOR HEAT TRANSFERRED FROM BUILDING ROOFS AND ROOF FINISHING SYSTEM USAGE .

Abstract

The object of this work is study the thermal behavior for building roofs which made from 150 mm concrete and cover with different materials instead of concrete roofing tiles ( graycolor ) at Baghdad city ( 33.2° N) ,its found that the concrete roofing tiles which painted by whitecolor gave 35 % saving value when compared with that energy consumed ordinary tiles ( beforepainted) while put the plastic tiles over that tiles gaves %28 saving value , and used the concrete roofing tiles which contained 8 mm insulated materials with fiber glass screen gives %27saving value and that tiles is less weight .
