Abstract
Building envelope of the structures plays a crucial role in the energy consumption. To decrease the amount of Energy Consumption in Building, Energy saving materials and Optimal sizing of Openings to be selected. In this aspect a model is simulated by using the Design Builder Software to Analyse the Spatial Daylight Autonomy, Thermal Comfort and Annual Energy Consumption. Windows impact the heat exchanges between indoor environment and outdoor environment. This possibly permit a proper utilization of solar energy. The research aims to investigate the influence of window-to-wall ratio in different of different climate conditions in India which has been introduced as hot dry, hot humid and moderate climates. The research has studied the most possible window-to-wall ration in the region based on previous work 5%, 10%,15% and 20% out of the faced surface area of the building. This paper sketch out the modus operandi and the alike results of an analysis which targets to find out the ideal size of the glazed surface, which permits the minimum amount of overall energy consumption and determining the efficient building materials .The analyses and simulation procedures were performed using Design Builder software and the window dimensions are calculated in terms of the ratio between the glazed surface to the gross facade area, defined as window to wall ratio (WWR).
Highlights
Buildings constitute the sizeable energy- consuming sector in the economy, with over 33% of all final energy and 50% of overall electricity preoccupied there
The necessity of the investigation was to examine the presence of an ideal dimension of the Window surface which is the size that allows minimum overall energy Consumption
We can say that SDA (Spatial Daylight Autonomy) is directly proportional to Window-WallRatio (WWR)
Summary
Buildings constitute the sizeable energy- consuming sector in the economy, with over 33% of all final energy and 50% of overall electricity preoccupied there. They are accountable for roughly 33.33% of the total carbon emissions globally. Doors and windows have a direct effect on the energy efficiency of the building and the quality of indoor thermal environment. Besides the window-to-wall ratio and the components of building envelope, building materials like wall materials, plastering materials and insulation materials influence the energy aspects of the building. Such as, orientation, window-to-wall ratio (WWR), heat transfer coefficient, shading coefficient, different building materials, wall materials, plastering materials and insulation materials under the circumastances of the local climate zone Windows. such as, orientation, window-to-wall ratio (WWR), heat transfer coefficient, shading coefficient, different building materials, wall materials, plastering materials and insulation materials under the circumastances of the local climate zone
