Abstract : To address the problems of ambiguous accounting boundaries, difficult quantification of hidden emissions, and insufficient pertinence of low-carbon paths in the whole life cycle carbon emission accounting of medical building materials, this study takes a newly-built 360 000 m2 tertiary general hospital as the research object. Based on the Life Cycle Assessment (LCA) method, a coupled model combining the IPCC carbon emission coefficient method and the material balance method was constructed, covering six life cycle stages. Empirical analysis and path optimization research were carried out focusing on core indicators such as carbon emission intensity and stage proportion. The results show that the carbon emissions of hospital building materials present significant stage concentration: the operation and maintenance stage accounts for 54. 3% , which is the core source, followed by the production and processing stage accounting for 20. 5% ; the operating rooms and inpatient buildings together account for more than 50% of the total emissions.  Radiation - shielding concrete has the highest carbon emission intensity (3. 2 tCO2 e/m3) , and concrete ranks first in total emissions due to its large consumption (32. 1%).  The emission reduction rate of resourceful recycling and disposal reaches 78. 8% . Green construction technologies achieve a 40. 1% emission reduction compared with traditional technologies, and the composite technology of " green construction + sterility optimization" can reduce carbon emissions in special areas by more than 20% with a cost increase of only 5%-8%. Finally, a four-in-one low-carbon path was established to achieve systematic reduction of carbon emissions, providing theoretical and practical support for the medical construction industry to implement the " dual carbon" goals.

Key words: carbon peak; building materials; whole life cycle carbon footprint; carbon emission accounting; low-carbon path optimization; LCA
