Abstract :

Introduction: Today, green architecture is referred to as a tool for improving the quality of the urban environment, optimizing energy consumption and reducing pollution. The purpose of this study is to model the amount of energy consumption in high-raise buildings under multiple scenarios and emphasize the facade of the building in green architecture. Materials and Methods: First, components related to the facade of high -rise buildings that are effective in optimizing energy consumption were extracted in two parametric and green architectural styles. Then, using the 15 -person expert panel, prioritized the components. In the third step, the statistical analysis was analyzed using questionnaire data and software. In the fourth step, it was used to simulate a hypothetical model of the Rhino Software, which was parametric by the Grassshopper plugin. Finally, they were analyzed in the form of multiple scenarios and energy consumption simulation.
Results and Discussion: Among the 18 components identified as Origami, 4 are factors "color", "form form", "opening position" and "material of materials" are involved in optimal energy consumption. The simulation results show that the annual radiation receipt in the initial model (base mode) is 2029.18 kWh. The parametric architectural pattern is 8.34 % more than the initial model of radiation. In the green architecture pattern, the increase in solar energy absorption was 9.98 percent higher than the base. In addition, the energy -saving rate in the green architecture pattern was 28.24 %, which was 11.11 % compared to parametric architecture. Among the components of optimal energy consumption used in the facade of high urban structures, the "material of materials" component with the coefficient of 130 has the highest share, followed by "color" and "albeado" components with coefficients of 120 and 110 respectively have. At the end of this ranking is the "number of openings" with a coefficient of 40.
Conclusion: Paying attention to materials such as the material of materials, the color of the materials, the type and position of the pop -up, the sex and angle of the canopies, etc. can reduce the amount of internal energy consumption of the building and on the other hand, by absorbing thermal energy in the cold season, the need To reduce energy.
