Abstract
Abstract:Background and Objective: Considering that about 44% of energy consumption is in the building sector, it is possible to create the best conditions for reducing energy consumption in each region by considering the criteria of thermal comfort indicators and providing passive solutions in building design. 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.Method: The research method in this paper is based on scientific research and simulation. 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. Based on Mahani and Givoni indices, the results and strategies for reducing energy consumption of buildings are presented. The Design Builder simulator was used to determine the quantitative effect of the proposed solutions by thermal comfort indicators.Results: By using the Mahani and Givoni Indicator's solutions and with passive solutions, 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.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 Givoni 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%.
