“…The grain warehouse is the most typical granary building, accounting for more than 85% of the total grain storage capacity in China [39]. In this study, 15 design parameters related to the energy use of grain warehouses (including three major categories of form parameters, envelope structure parameters, and equipment parameter) were summarized, with the specific parameter names and the ranges of variation shown in Table 1.…”

The early design parameters exert a considerable influence on the cooling energy demand of a granary building in operation. In order to investigate the impact of various parameters on energy use, a grain warehouse energy model was constructed using the Ladybug + Honeybee tools on the Grasshopper platform. Three global energy sensitivity methods were used to analyze the model, and the sizes of the influential parameters were determined and ranked. The study uncovered that the cooling energy demand of the grain warehouse was primarily influenced by factors such as the cooling set-point temperature, roof solar absorptance, roof and exterior wall insulation thickness, window type, and orientation. On this basis, a local sensitivity analysis was conducted for the highly sensitive parameters to identify their influence trend and optimal design range. The results showed that the cooling energy demand of the grain warehouse increases faster as the cooling set-point temperature decreases, with the highest growth rate occurring at a temperature below 18 °C. Lower solar absorptance of the roof is conducive to reducing the cooling energy demand of the grain warehouse. When the thickness of the roof thermal insulation is less than 120 mm and the thickness of the external wall thermal insulation is less than 60 mm, energy use decreases more quickly with greater insulation thickness. It is advisable to use traditional or new windows with thermal insulation and shuttered windows. Furthermore, the optimal position of the long side of the granary was between 10° west and 10° east of north. This research could provide guidance for the energy-saving design and renovation of granary buildings in cold regions of China.

The traditional brick bungalow is not conducive to long-term grain storage because of its poor thermal insulation. In this paper, a new type of wall element for grain bungalows with both load-carrying and thermal insulation functions, called a “Structure-Insulation” integrated wall panel (SIW), is proposed for improving the grain storage environment. To study the thermal insulation reliability of SIW under multivariable randomness and the availability of different grain storage zones, a finite element model was established based on the test. Then, the failure criterion was established with the heat transfer coefficient as the key point and 1,000,000 sampling calculations were carried out by the Monte Carlo method. The reliability was discussed and sensitivity of random parameters was quantified. The thermal performance test shows that the heat transfer coefficients of the two designed SIW wall panels compared with the traditional brick bungalow wall are reduced by 45.81% and 56.13%, respectively. The thickness of the insulation panel is sensitive mostly to the thermal insulation performance, with a correlation coefficient of 0.877. When the thickness of the insulation panel is 80, 94, and 107 mm, the wall panel can meet the limit requirements of the heat transfer coefficient of the granary enclosure structure of 0.59, 0.53, and 0.46 , with reliability indexes of 3.08, 1.82, and 1.75, respectively. The research results provide an important reference for the design, optimization, and application of SIW wall panels in thermal insulation.
