Evaluation study on energy consumption and carbon dioxide emissions in Jiangsu province

Abstract

This research divides the building life cycle into five stages: building materials production, building materials transportation, construction, operation and use, and demolition. At the same time, this study collected data from 262 cases of buildings under construction and completed in Zhejiang Province, established a database of building life cycle energy consumption and CO2 emissions inventory in Jiangsu Province, and finally evaluated the system framework to discuss the energy consumption and CO2 of different types of buildings at different stages. Emission characteristics. The main contents are as follows: 1. Establish a material emission inventory for each stage of the construction life cycle in Jiangsu Province Review the previous research and sort out the emissions of 27 main materials (basic inventory data of energy consumption and emissions in the five stages of building materials production, building materials transportation, construction, operation and use, and demolition and disposal) on this basis. 2. Analyze the characteristics of building energy consumption and CO2 emissions in Jiangsu Province Collected lists of 44 building materials used in Nanjing and used energy consumption lists of 262 residential buildings. Through data analysis, we can understand the energy consumption and CO2 emission characteristics of different types of buildings at different stages. 3. Establish an evaluation system for LCA energy consumption and CO2 emissions in Jiangsu Province Based on the summary of the material emission inventory and the emission characteristics of buildings in Jiangsu Province, this study established an LCA evaluation system framework suitable for buildings in Jiangsu Province, and gave calculation methods with different accuracy according to the level of detail of different inventory data. Finally, this research selects Chenggong Middle School as a case for method practice.
