Summary, etc. Solar heat gain (SHG) through fenestration (window) dominates towards cooling demands in buildings and eventually increases electricity consumption. Integration of fixed shading devices (i.e. overhang) can reduce the solar heat gain through and overall energy consumption. In this manuscript, solar heat gain factor (SHGF) has been assessed for different designs of overhang. ASHRAE method of fenestration design and heat balance has been used for the estimation of the SHGF and solar gain in the buildings of different designs of overhangs. Further, the SHGF and solar gain have been used to determine accurate heating and cooling loads.The values have been estimated for the peak winter and summer months of December and June for Indore city, India. Significant reduction in heating and cooling loads in the buildings having windows with overhangs has been estimated in winter and summer seasons. Integration of overhang lowers the energy demand by over 50% and 30% in rooms having windows in south and east/west walls respectively. The results of the this study would be extremely beneficial for designing the fixed type shading device in buildings in order to controlthe heating and cooling loads and in achieving the sustainable development goals (SDGs 11, 12 & 13)
