【专家解说】：Presented as a low-carbon building evaluation framework in this paper are detailed carbon emission account procedures for the life cycle of buildings in terms of nine stages as building construction, fitment, outdoor facility construction, transportation, operation, waste treatment, property management, demolition, and disposal for buildings, supported by integrated carbon intensity databases based on multi-scale input–output analysis, essential for low-carbon planning, procurement and supply chain design, and logistics management. As one of the main energy consumers, buildings contribute to high terminal carbon emission. Restraining building-related carbon emission can play an important role in context of energy conservation and global climate change. An assessment framework for low-carbon buildings is presented in this study with the introduction of systems carbon emission indicators and detailed carbon emission account procedures for the life cycle of buildings in terms of nine stages as building construction, fitment, outdoor facility construction, transportation, operation, waste treatment, property management, demolition, and disposal, with related material, equipment, energy and manpower inputs inclusively covered. With existing carbon intensity databases supportive for the systems carbon account extensively reviewed, the basic scheme and algorithm for multi-scale input–output analysis for emission intensities are presented for the construction of more consistent carbon intensity databases for the globalized economies characterized by multi-scales. Besides for post-assessment of life-cycle performance of building, the multi-scale consistent databases with extensive coverage in both scales and objectives are useful to compare the carbon emissions embodied in substitutable materials from different sources, which is essential for low-carbon planning, procurement and supply chain design, and logistics management.
