Thermal Performance Evaluation of Mud House for Ghaziabad Composite Climate Subhash Mishra* Department of Mechanical Engineering Inderprastha Engineering College, Ghaziabad Dr. APJ Abdul Kalam Technical University, India. * subhashmishra.2008@rediffmail.com Abstract In this paper, we discussed about performance parameter like (Energy saving, Heat transfer rate and Total annual cost) in Mud wall building by selecting a proper insulating material and optimum thickness of insulation. Thermal conductivity and cost of insulation material are important factors that should be considered for selection of insulation material. At optimum insulation thickness, the cost of heating/ cooling to obtain comfort condition is minimum. So it is necessary to save the energy by using optimum insulation thickness. This work has been analyzed by MAT LAB Programming. Mud has high specific heat capacity, which reduces the thermal gradient of Mud house so that heat transfer rate for Mud wall construction has less value as compared to other types of construction. It is observed that room air temperature of Mud house is less in summer and higher in winter season as compared to other types of construction. Transfer of heat across the boundary of Mud wall construction has been calculated by using Degree-Days Method. As a result, it can be concluded that the overall energy saving of 54 % has been suggested by using mud insulation as compared to other insulation material and the optimum insulation of Mud wall has been found as 67 mm. Keywords - Energy Saving, Thermal Conductivity, Mud Insulation, Optimum Insulation Thickness, Heat Transfer Rate. Introduction Energy saving means to efforts made to decrease energy consumption. Energy saving can be done by using efficient energy sources, in addition with decreased energy consumption or reduced consumption from conventional energy sources. Some of the energy saving can be achieved by using suitable insulation thickness in building walls. In residential application, the most effective method of energy saving is to use proper insulation material. Day by day energy consumption rate has gradually increased due to Technological development, population growth, urbanization and industrial growth. Population growth means energy consumption has increased due to more building construction. It is necessary to save the energy due to inadequate energy resources, higher price of fuels and environmental pollution coming from burning of fuels. The energy conservation is achieved by the application of thermal insulation in buildings. Energy conservation supports the eco-friendly environment by providing energy saving in the terms of money. The heat transfer from outer envelope of building can be reduce by using thermal insulation. Thermal insulation is the best method to make heat proof house. An insulated home is more comfortable as the temperature remains stable over changes of weather. It keeps the temperature of building cool in summers and warm in winters. It is very necessary to preserve the temperature of the house independent from atmospheric temperature for energy saving. If the thermal conductivity of wall material is less, then less insulation will be required for a given extent of cooling and more operating volume will be available. The main purpose of Insulation is to decreases fuel consumption, unwanted emissions from the burning of fossil fuels and increases thermal comfort by reducing heat losses from building wall boundary.
