Different climatic conditions have an impact on a building’s performance. Climate-related factors will also affect how energy-efficient a structure is. As a result, making comparisons between buildings in various climate zones will produce inappropriate results. It is crucial to understand how much a building’s energy performance can vary depending on the climate. By running energy simulation on the typical building, the climatic condition ratio is established for various climate zones of India in order to increase the accuracy of building assessment rating tools. The purpose of this paper is to study the effect of the size, position and direction of windows on the amount of energy required for cooling and heating of an indoor room situated within different climatic conditions in India, According to the study’s findings, the size of a building’s windows is the important and the primary factor responsible for influencing the cooling and heating load requirements and energy efficiency of a building or a single room. By selecting the ideal window size, which for an autonomous façade is between 10% and 50%, one can minimise energy usage by 40% and CO2 emissions by 30%. An autonomous façade’s cooling and heating demand is significantly impacted by orientation. The worst heating and cooling load requirement is at an orientation of 70°E to the south-east. The findings indicate that the south is the optimum direction for the amount of energy needed for winter heating and the north is the best direction for summer cooling.

Abstract
n
Different climatic conditions have an impact on a building’s performance. Climate-related factors will also affect how energy-efficient a structure is. As a result, making comparisons between buildings in various climate zones will produce inappropriate results. It is crucial to understand how much a building’s energy performance can vary depending on the climate. By running energy simulation on the typical building, the climatic condition ratio is established for various climate zones of India in order to increase the accuracy of building assessment rating tools. The purpose of this paper is to study the effect of the size, position and direction of windows on the amount of energy required for cooling and heating of an indoor room situated within different climatic conditions in India, According to the study’s findings, the size of a building’s windows is the important and the primary factor responsible for influencing the cooling and heating load requirements and energy efficiency of a building or a single room. By selecting the ideal window size, which for an autonomous façade is between 10% and 50%, one can minimise energy usage by 40% and CO2 emissions by 30%. An autonomous façade’s cooling and heating demand is significantly impacted by orientation. The worst heating and cooling load requirement is at an orientation of 70°E to the south-east. The findings indicate that the south is the optimum direction for the amount of energy needed for winter heating and the north is the best direction for summer cooling.
