In this age of ever depreciating conventional energy sources and increased problems of climatic conditions,
the need for conservation of energy and confronting indoor air quality has become irreplaceable from the civil purpose.
Therefore, it becomes very important to incorporate computational analysis while designing buildings and homes, which
will help to maintain optimum control over internal climatic conditions along with the efficient utilization of energy. This
work aims at studying one such idea, to analyze the building design before erection from the perspective of maintaining
optimum thermal comfort to the human body, with the help of Computational Fluid Dynamics and therefore further
providing suggestions for improvements in optimizing the energy consumption based on design changes prior to the
actual implementation. Qualitative measurements for optimum building design are studied in terms of physical variables
like PMV and PPD to get conclusive results on indoor air quality.
