Abstract

Evaluation on the carbon emissions of large public buildings and carbon reduction measures are very important to help reach carbon peak demand and carbon neutral. The purpose of this study is to conduct energy audits and energy-saving assessments on large public and commercial buildings to find out the impact of various behavioural activities related to buildings on carbon emissions and energy consumption, and to explore the carbon reduction potential of buildings. In China, the energy structure based on fossil fuels will not change in a short term, and energy consumption will inevitably increase with economic development; however, the energy efficiency is the main factor that affects the building carbon emissions. And changing energy efficiency will reduce emissions by 9.29%, while improving the energy structure will reduce emissions by only 0.46%; it is the key work to slow down greenhouse gas emissions in buildings that is reducing power consumption of electrical equipment, especially the air-conditioning system, which can result in 49.72% energy saving after reforming.
