| Abstract | ||||
| This Paper presents a thermal investigation of four traditional houses tested experimentally under the effect of external climatic conditions of hot dry region in Egypt (Toshky region). The external and internal walls of the test house were constructed from local sandstone blocks with 50 cm thick. The ratio between the external openings and the external walls surfaces areas is less than 10 % . The external wall is covered internally with 2-3 cm cement mortar plasters, while the internal walls covered with 2-3 cm cement plaster from both sides. Volts and domes covered the roof of the test houses. The external surface of the roof covered with 2-3 cm white cement mortar plaster. Results demonstrated that the local building materials (sandstone) suppress the swing of external outdoor air temperature and stabilize the indoor air temperature at average level below the average of outdoor air temperature by about 2-3 OC during the hottest period. The results also show that it is possible to maintain the indoor air temperature significantly below the average of the outdoor air temperature by about 4-5 "C, when modem insulating materials together with the local building materials are used. Besides, the use of passive cooling systems (evaporative cooling) maintained the indoor climate in the thermal human comfort zone. | ||||
