The normal energy consumption of any building has been on the rise since the past few decades. And the majority of the energy that one spends goes into HVAC. Due to the increasing heat from global warming, vehicular heat and urban heat island effect etc. the indoor temperatures have gone beyond livable conditions. And so almost every building is equipped with one or more air conditioners. As a result of that the energy consumed by each house increases, resulting in an overall energy scarcity. Studies show that the exterior walls and roofs of a building absorb heat during the day and conduct the heat absorbed into the building, which increases the indoor air temperature. This project is an attempt to identify the building materials that contribute very little to indoor air temperature and their effects on energy consumption. The indoor air temperature may vary based on several factors such as, thermal conductivity, emissivity, reflectance etc. of the materials used in construction. Based on these factors, computerized analyses in various Building Information Modeling softwares are done to identify the best suited materials for our climatic conditions. And a comparative study is done to show the variation in construction and operational costs of a building when these materials are used over conventional materials.
