Abstract.Aiming at the energy consumption issues of civil hotels, this study takes a hotel in Shanghai as an example and uses DeST simulation and orthogonal tests to analyze the effects of exterior wall insulation thickness (60-100 mm) and window materials (common insulating glass, Low-E coated low-emissivity insulating glass, Low-E coated vacuum glass) on building energy use. Results show that window materials have a more significant impact (range: 36,088 kW·h). The optimal scheme (100 mm insulation + Low-E coated low-emissivity insulating glass) achieves the lowest total load of 289,114 kW·h, saving 23.9% energy compared with the baseline. Prioritizing window upgrades to balance efficiency and cost is recommended for low-carbon building development.
