Abstract：Focusing on the typical granary in Hainan,the thermal insulation and energy-saving potential of self-ventilated double-deck roof structure was discussed.By summarizing the main types and roof forms of the current granary,using Designbuilder software,the double-roof granary structure was built as the main model,and the single-roof granary model was set as the reference model,and the thermal insulation performance and energy consumption performance of the two roof structures under the same conditions were compared and analyzed.The results show that the average surface temperature of the lower plate of the double-layer roof is 5.5℃lower than that of the single-layer roof in July,and the overall cooling load of the granary is reduced by 1 379.8 kW.In granary building,compared with single-layer roof,double-layer roof has obvious advantages of heat insulation and energy-saving.
