The ob jec tive of this study was to as sess the ther mal per for mance and eco nomic assess ment of dif fer ent types of clay and con crete ma sonry brick wall sam ples used in build ing con struc tion. In this study, eigh teen types of clay bricks and two types of con crete bricks were an a lyzed for ther mal per for mance. The bricks were clas si fied and grouped based on the brick con fig u ra tion, ma te rial, and size. The anal y sis of the re sults shows that the equiv a lent ther mal

The bricks having same con fig u ra tion and size, the equiv a lent ther mal con duc tiv ity vari a tion is large de pend ing on the type of ma te rial used, es pe cially for con crete brick. In general, the brick with lesser thick ness has lower con duc tiv ity as com pared to those hav ing higher thick ness. How ever, the ef fect of brick length on equiv a lent ther mal con duc tiv ity is in sig nif i cant. The eco nomic anal y sis showed that the in su lated clay brick type 16 is the most eco nom i cal brick among the types of brick stud ied. Moreover, it is worth while to note that the net pres ent value of nor mal con crete brick (type 19) is re duced by about 45% by mak ing the con crete brick light weight (type 20).
