This document summarizes a study on modeling and parametric analysis of an office building in New Delhi to evaluate thermal comfort and energy consumption. Key parameters analyzed included glazing area, glazing type, insulation, thermal mass, shading devices, and orientation. The study found that internal and external shading devices had the most significant impact on thermal comfort and energy use, followed by roof insulation. A 50% reduction in glazing area and the use of shading devices resulted in a 36.8% decline in total energy consumption compared to the base model. Orientation was also found to impact energy use, with buildings facing east-west requiring more insulation.
