Energy saving and carbon reduction paths of residential buildings in Sanjiangyuan area under carbon peak background

Reducing carbon emissions in the building sector is of great significance for energy saving and carbon reduction of residential buildings and ecological environmental protection in Sanjiangyuan area. This paper analyses the influencing factors of carbon emissions in the building operation stage, uses the scenario analysis method to forecast the carbon emissions of residential building operation in Sanjiangyuan area in the medium and long term, and puts forward the target and path of achieving carbon peak of residential buildings in this area. The study results show that the carbon emissions of residential buildings will reach 2.21 million tons in 2030 under the basic scenario, still showing an increasing trend. Under the peak scenario, the carbon emissions of residential buildings will peak at 1.74 million tons in 2030 and then decline slowly. Reasonable control of building scale, implementation of clean heating, implementation of higher energy efficiency standards for new buildings, energy-saving renovation of existing buildings and promotion of electrification and renewable energy are the core measures for energy saving and carbon reduction of residential buildings in Sanjiangyuan area.
