Abstract: (16 Views)
Introduction: Today, energy is the source of life and modern human life. However, due to population growth and technological progress, energy consumption in life has increased drastically and has led to the emission of greenhouse gases and climate changes, which have caused many problems for the health of the environment and human societies. For this reason, reducing energy consumption in residential buildings seems essential. The facade of the building, as a connecting factor between the interior and the exterior, plays an important role in reducing energy consumption in residential buildings. Therefore, one of the effective methods to control and improve the quality of building energy consumption and thermal performance and ultimately reduce energy consumption in residential buildings is the use of double-layer facades. The purpose of this research is to measure the amount of energy consumption reduction in residential buildings using two-shell and integrated facades in three modes of natural ventilation, mechanical ventilation and no ventilation in the climate of Kermanshah city.
Method: To achieve the goal of the current research, first the geographical location of the sample was determined. In the next step, the weather data of Kermanshah city was collected. Using Design Builder software, the basic sample, simulation and existing scenarios were analyzed and measured. The accuracy of the simulation results was validated with the values listed in the annual electricity and gas bills of the building under study. The difference between the software output and the actual values was less than 10%.
Findings: consumption because it has a direct effect on reducing energy consumption in these buildings. Investigating and comparing the energy consumption and thermal behavior of the second shell of the building, air conditioning between the two shells in the hot season has determined the most optimal mode of energy consumption for the whole building.
conclusion: The findings show that design ability and creativity are essential and vital skills for the development and progress of any industry and profession. One of the strategies used to strengthen design ability is the use of constructivist educational model in design workshops. This model is known as a very effective approach to develop and improve the design process. which can strengthen design ability and allow designers to respond creatively and innovatively to design issues and challenges and also encourages designers to use creative and innovative approaches in design and look for new solutions and continuous improvement.
