Energy Efficient Green Building Based on Geo Cooling System in Sustainable Construction of Malaysia

This paper is focused to utilize geo energy in cooling of building in tropical country like Malaysia where temperature rises in daytime and goes beyond to a comfortable limit. In daytime inside temperature of the room is considered to be reduced by adding thermal conductivity media inside the room elements such as walls through its connectivity to the underground where temperature is less than the ambient room temperature. Due to the ground connectivity of thermal conductivity media a flow of heat creates from the room to the ground and tries to produce a thermal balance between these two medias and therefore, room temperature drops to a temperature close to the underground soil temperature. Aluminium pipes are considered as high thermal conductivity material. The entire study is done numerically using ANSYS 11 finite element software to determine the role of underground soil and thermal conductivity pipes. In numerical investigation heat flow between two systems (building rooms equipped with thermal conductivity pipe and underground soil) is studied and the performance of the conductivity materials is examined. The room temperature in the presence of thermal conductivity media as well as mechanical cooling system is also investigated in this study. It is seen that high thermal conductivity media plays a role in transferring heat from room to the ground and makes cooling of the building effectively. It acts also effectively when it uses with other mechanical cooling system of building

Earth Architecture from Ancient until Today

AbstractEarth Architecture is a study devoted to the architectural uses of earth in shaping the environment of humankind, a subject closely related to human ecology. Earth Architecture includes contemporary as well as historical and vernacular examples drawn from many cultures and periods. Structural built of earth presently house an estimated 1.5 billion people about 30 percent of the world's population (Keefe 2005). Archaeologists have found evidence of mud brick buildings constructed as early as ten thousand years ago in the Middle East and North Africa, where impressive buildings up to ten stories high have been recorded in an unbroken architectural tradition that continuous today. Although creating individual earth structures is a familiar practice in many areas of the world today, the practice of reshaping the earth to create new human environments is little known. The current paper is a review on earth architecture from ancient until today

The role and function of thermal insulation in architecture

With movement of cities toward a more industrial urban structure, they need of green environment is increasing. One of the solutions is creating the green roofs which the interest on them is increasing. However, having a green roof requires some technical guidelines to provide the desired environment. The technical guidelines for instruction of green roof aim to provide an adapted, environmental friendly and suitable material for offering the optimal operation. This focus of this document is mainly on the technical aspects of the material in need for insulation, roofing membranes and protection material, moisture-retention material and water proofing
