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.
