Abstract
Rammed Earth is a suitable technique for building in desert climate. Thick walls regulate the interior space of the building. A building of an area of about 90 square meters was built of rammed earth in Banban, north of Riyadh. Moist soil is rammed manually in wooden forms. Small percentage of gypsum and lime was used as stabilizer. Compressive strength of samples was around 1 Mpa. Earth tube was used too cool the building. The tube is 1.6 m under the ground and runs for 40 m with diameter of 0.25 m. The air coming out of the tube is about 10 degrees less than that of the outside ambient temprature.
