根据国际能源署的数据，建筑物是全球最大的能源消耗部门，2013 年产生的温室气体排放量占三分之一以上。可利用太阳能等可再生能源来全部或部分满足建筑物的能源需求。在这项研究中，建筑物中使用太阳能集热器来提供地暖系统所需的热水。伊朗大不里士、德黑兰和基什岛这三个气候条件独特的城市被认为可以更好地了解太阳能地暖系统在不同气候下的性能。此外，还进行了经济分析以评估所提出系统的可行性。 DesignBuilder软件用于模拟建筑物的能源性能。结果表明，位于德黑兰、大不里士和基什岛的设有太阳能集热器的建筑年燃料消耗量比没有集热器的建筑分别减少了125.39、303.58和1.41MWh。德黑兰、大不里士和基什岛系统的投资回收期分别为 8.2 年、9.4 年和 12.1 年。
According to the International Energy Agency, buildings are the largest energy-consuming sector globally, producing over one-third of greenhouse gas emissions in 2013. Renewable energies such as solar can be harnessed to fully or partially meet the energy demands of buildings. In this study, solar thermal collectors are used in a building to provide the hot water required for an underfloor heating system. Three cities in Iran, namely Tabriz, Tehran and Kish island, with distinctive climatic conditions are considered to gain a better understanding of the performance of solar-powered underfloor heating systems in different climates. Moreover, an economic analysis is conducted to assess the feasibility of the proposed system. DesignBuilder software is applied to simulate the energy performance of the building. The results indicate that the annual fuel consumption of the building with a solar collector located in Tehran, Tabriz and Kish island is reduced by 125.39, 303.58 and 1.41 MWh compared to that of without collector, respectively. The payback period of the system for Tehran, Tabriz and Kish Island is found to be 8.2, 9.4 and 12.1 years, respectively.
