Hospital buildings provide healthcare services at the costs of significant amounts of energy consumption and carbon emissions, further exacerbating the environmental load. Because of the limited research on the life cycle carbon emissions of Chinese hospitals, this study conducted a detailed carbon-accounting and comparative study. Firstly, BIM and LCA were used to quantify the carbon emissions of the inpatient building in each stage of the life cycle. Secondly, the differences in carbon emissions by stage were compared on the basis of 20 cases of public buildings. The results show that the whole-life carbon emissions of the inpatient building was 10,459.94 kgCO2/m2. The proportion of operational carbon emissions was 94.68%, with HVAC (52.57%), equipment (27.85%), and lighting (10.11%) being the main sources. Embodied carbon emissions accounted for 4.54%, and HRB400 steel and C30 concrete were the main sources of carbon emissions. Hospitals are second only to emporiums in terms of operational carbon intensity, being 1.71 and 1.41 times that of schools and office buildings, with inpatient buildings being 3 and 1.7 times that of medical complexes and outpatient buildings, respectively. The future sustainable development of hospital buildings should promote efficient building performance and good environmental quality, both in terms of energy efficiency and carbon reduction.

“…DT concretely opens a new approach to support design and management in the lifecycle of buildings [80][81][82][83]110,121]. Thanks to interoperability and information management, it could improve productivity; reduce the impact of buildings and infrastructures on the environment; enhance sustainability, circularity, and green construction; and predict more accurate outcomes and in-use behavior, reducing waste, risk, and costs in the lifecycle [84,85,[122][123][124].…”

In 2011, the term Digital Twin was originally introduced by Michael Grieves to define the synchronization between two realities: physical objects placed in a real space and virtual objects within in virtual space, linked through the mutual exchange of data throughout the entire lifecycle, both in real-time and asynchronously. Nowadays, Digital Twin is among the principal and emerging technological innovations of both Industry 4.0 and the emerging Industry 5.0, enabling an interaction between physical and virtual objects, Big Data, Internet of Things, and Artificial Intelligence. The construction sector, too, is now exploring the potentialities offered by the Digital Twin approach in enhancing innovative, responsible, and sustainable governance of buildings’ lifecycles. Concerning these issues, this paper proposes visualizing future challenges with a specific focus on the operation and maintenance phase and its related impact on decarbonization via a critical literature review of the current statements. The applied methodology is based on three different questions related to certain research issues performed in the Scopus database. The selected findings were filtered, classified, and discussed. Some future challenges on specific issues have been identified, defining and promoting novel research ideas.
