Research on Carbon Emission Calculation of University Teaching Buildings under the Dual-Carbon Goals—Taking a University Teaching Building in Chengdu as an Example

In the context of an increasingly severe global ecological crisis, promoting green and low-carbon transformation has become a major issue that all humanity is facing together. The Chinese government has clearly set the strategic goals of carbon peak and carbon neutrality, demonstrating the responsibility and commitment of a major country. The construction industry, as an important sector in terms of energy consumption and greenhouse gas emissions, its low-carbonization process directly affects the realization of the country's emission reduction targets. This study focuses on a teaching building of a university in Chengdu region. Through a systematic examination of its architectural features, thermal performance of the enclosure structure, energy system configuration and operational energy consumption characteristics, a scientific and comprehensive carbon emission assessment system is constructed, and based on this, multi-dimensional carbon footprint analysis is carried out. This research not only provides data support and technical routes for the subsequent implementation of energy-saving renovations and low-carbon upgrades of the case building, but also creates a replicable model for the sustainable development practices of similar public buildings.
