Abstract :

Background and objective: About 44% of energy consumption is in the building sector and attention to thermal comfort indices and passive solutions can reduce energy consumption in different areas. The aim of this study is to investigate the thermal comfort situation in Ilam city and providing construction solutions appropriate to the climate of this city.Material and Methodology: In this study, a descriptive and simulation method was used. In order to achieve the architecture-compatible architecture of the climate in the city of Ilam, a 28-year statistical analysis (1988-2016) of the city's synoptic station, the criteria presented in four thermal comfort indicators have been used. The Design Builder simulator was used to determine the quantitative effect of the solutions presented in Mahani and Gioni indices solutions by thermal comfort indicators.Based on Mahani and Gioni indices.Findings: By using of the solutions presented in the Mahani and Gioni Indicator's, the building can be in the comfort zone for eight months from the year of the day and five months from the year without any energy consumption. In addition, building orientation, the relative percentage of openings and the use of heavy materials in walls and ceilings have the greatest impact on reducing the energy consumption of buildings.Discussion and Conclusion: Energy savings plans that are possible in the early stages of design (building orientation, openings) will result in a 20% reduction in energy consumption, according to the Mahani and Gioni indicators. In addition, replacing heavy materials instead of materials in common building walls can reduce energy consumption by 39%. In general, utilizing the principles of climate design can reduce the amount of energy consumption by 52%.Considering to the criteria given in the Mahani and Gioni indicators for building orientation and openings can reduce the energy consumption of the building by 20%. Reduce Also, replacing heavy materials with conventional building materials can reduce energy consumption by 39 percent. Overall, using climate design principles can reduce energy consumption by 52%.
