Carbon Emissions Measurement and Carbon Reduction Strategies for Existing Buildings

As humanity realizes the severe consequences of global warming, carbon emissions have gained widespread attention. Comrade Jinping Xi pointed out in the 20th Party Congress of the People’s Republic of China that we should steadily promote carbon neutralization, improve total energy consumption and intensity regulation, and gradually shift to a “dual control” system for total carbon emissions and intensity. The construction industry undoubtedly has substantial carbon emissions compared to other industries, but it also presents a significant opportunity for emissions reduction. Therefore, this paper will take a campus dormitory building in Heilongjiang, China, as an example and use the building carbon emissions measurement model to measure the carbon emissions of the building and propose energy-saving and carbon-reducing measures for the campus dormitory building. The results show that the total carbon emissions in the construction phase of the building is 12,000.02 t, and the full carbon emissions in the one-year operation phase is 72,213.72 kg. The carbon emissions in the operation phase of the building mainly comes from the air conditioning, electrical lighting system, and heat transfer between the building and the outside world, and there is more room for carbon reduction in such buildings. Based on the above analysis, this paper analyzes the ways and strategies of energy saving and carbon reduction in campus dormitory buildings from four aspects: technology application, energy consumption behavior, material energy efficiency, and clean energy. This paper provides a reference and reference for the study of carbon emissions measurement and carbon neutral work of existing dormitory buildings in universities, and provides suggestions for the construction of low-carbon and sustainable campus buildings.
