Abstract - This project aims to provide an overview of the

the thermal load, thereby resulting in remarkable energy savings. PCMs are implemented to minimize the cooling and heating loads through the building envelope due to their massive potential for energy storage during melting and solidification, thereby maintaining an acceptable thermal comfort. Paraffin and beeswax are the most commonly available PCMs that can be incorporated with gypsum mortar to make gypsum boards, which can be used as facades, partition walls, and also when incorporated into building components such as walls, ceilings, or floors.

role and potential of PCMs in enhancing the energy efficiency and comfort of buildings. Phase-changing materials (PCMs) have garnered considerable attention as thermal control materials in buildings due to their ability to store and release large amounts of energy during phase transitions. Paraffin and beeswax are two commonly used phase-changing materials (PCMs) that offer effective temperature control in buildings. Paraffin wax and beeswax both exhibit phase transitions at temperatures suitable for building applications. The paraffin and beeswax integrated into building materials like gypsum mortar offer several advantages. Firstly, it reduces the reliance on mechanical heating and cooling systems, thereby lowering energy consumption and utility costs. Additionally, it enhances thermal comfort by stabilizing indoor temperatures and reducing temperature fluctuations. Furthermore, paraffin and beeswax PCMs contribute to environmental sustainability by reducing carbon emissions associated with conventional heating ventilation and air conditioning (HVAC) systems. Performing a thermal analysis of paraffin and beeswax integrated into the gypsum mortar using ANSYS software involves simulating the heat transfer behavior of these phase-changing materials. Steady-state thermal analysis is done, and compressive strength is identified by performing compression tests on gypsum and PCM-incorporated cubes. By comparing the results, it is found that the combination of gypsum with paraffin is more effective in terms of thermal control than gypsum with beeswax. But compressive strength is greater for the combination of gypsum and beeswax.

analysis for stress v/s strain curve.

4. THERMAL ANALYSIS USING ANSYS ANSYS is used to identify how a product will function with different specifications, without building test products or conducting crash tests. It uses computer-based numerical techniques to solve complex problems. The range of problems ANSYS can solve is immense and could be anything from fluid flow, heat transfer, stress analysis and many more.

4.1 Steady State Thermal Analysis Steady-state thermal analysis using ANSYS involves analyzing the temperature distribution within a structure or system when the temperature does not change with time. Maximum of 100℃ is applied and the minimum temperature obtained for gypsum board, gypsum + Paraffin with 5 different percentage and gypsum + beeswax with 5 different percentages is shown in the following figures

Energy consumption in buildings has become one of the most urgent issues in most countries worldwide. Globally, the energy consumed for space heating and cooling is as high as 40% and 61% of the total energy demand in commercial and residential buildings, respectively. The incorporation of phase change materials (PCMs) into building envelopes has the desired impact of controlling
