Passive design is the integral part of design process. In India modern buildings are majorly depends upon mechanical means for heating and cooling. To reduce the dependency on the artificial means is challenge for designer. This study gives an overview of different passive design strategies used in the buildings of composite climate. A detailed review was conducted on the assessment criteria given in GEM sustainability rating system. These criteria was grouped according to responsive strategies, conservation of water resources, landscape and site plaining Etc. Based on point system given in the ASSOCHAM GEM rating different cases from similar climatic zones were evaluated. A detailed analysis of a live case from composite climate was performed using simulation method and shadow analysis. Quantification of daylight exposure evaluates the impact of size and position of window openings. It is found that basic building configuration and orientation plays an important role in creating balanced thermal environment inside the structure. After relative study of different cases it was found that building with the proper orientation and ventilation fulfill the requirements prescribed by the GEM ratings.

“…So, it is crucial to take into account the impact of lateral loads, such as earthquakes and wind loads. Because the Key causes of structural collapse include dynamic excitations like winds and earthquakes [1] [12][13]. The term "wind" refers to moving air and is frequently used to refer to the atmosphere's horizontal motion within a building.…”

Since the necessity for larger and slimmer structures has arisen in Bangladesh, wind engineering has become increasingly important. The traditional approach of manual high-rise building design is time-consuming and prone to human mistakes. ETABS is a structural program that is currently widely used by structural engineers to handle common problems such as static analysis, wind analysis, and confirming multiple codes using various load combinations. The study's purpose is to compare wind pressure's impacts on eight distinct places in Bangladesh. ETABS 9.6 software with the BNBC provision was used to conduct this research on a 106-foot residential building. The study's major goal is to examine the reactions of stories, narrative displacement, and drift under the influence of wind in eight major distinct areas out of five divisions of Bangladeshi areas. Based on the investigation findings, we attempted to determine their attitude to various wind pressures. Analysis shows that wind pressure in the South-East and South-West is higher than in the North-East and North-West and most of it is found in the South-East.

The wind load and pressure on a tall hexagonal structure altered as the apertures changed in this study. In various conditions, wind angles ranging from 0 to 90 degrees with a 30-degree gap are being used. The distance between the interference building and the model building was gradually raised from 50mm to 200mm at 50mm intervals. At a scale of 1:500, the main building model was studied. The ANSYS CFX package's validity was also tested using a rigid model with dimensions of 100mm x 100mm and a height of 700mm. The k-ε-turbulence model was utilised in the investigation, which was conducted using Computational Fluid Dynamics (CFD) and the ANSYS CFX software package. According to the analysis, changing the percentage of opening area has an influence on building stability because it affects the pressure on the leeward and windward faces. Contours and vortex formation were used to highlight the relationship between different scenarios. As the distance between the interference and model buildings expands, so does the pressure coefficient of the faces. The effects of apertures on the model building were also investigated, with 5-40% openings provided.
