6.2 Framework of LCSA 163

FIG. 8.7 The differences between (A) the completeness check and (B) the consistency check.

6.2.5 Life cycle costing and social life cycle assessment

The overall framework of LCC and SLCA are the same with LCA, which includes goal and
scope definition, life cycle inventory, LCI assessment, and interpretation, as shown in Fig. 8.8.
The LCC and SLCA of the same object should share the same research boundary. The material
flows and energy flows should be replaced by cash flow for LCC and be replaced by social
related indexes for SLCA. Similarly, in the impact assessment for LCC and SLCA, the data
should be transformed into economic-related and social-related impact values.
As there are no international standards for LCC and SLCA, there is more space for re-
searchers to create innovative methods or adjust the current method within the LCA framework
to create more suitable sustainability assessment methods that match the practical situations.
