Abstract：

Dynamic life cycle assessment (DLCA) of buildings is an emerging research topic, which lacks systematic analysis of representative methods and tools. In order to help practitioners better understand and apply, literature in English and Chinese from 2010 to August 2024 is collected through a systematic literature review approach, and it is found that the field is gaining attention in Europe, Asia and North America. The existing methods can be summarized into four types: dynamic matrix method, improved dynamic matrix method, dynamic life cycle cost method and simplified DLCA method, and the promising software tools are DyPLCA, Temporalis, VERIFY, premise, and Futura. The database modification tools generally have the problem of mismatch between the modeling method and the corresponding life cycle inventory (LCI) of the common database. In the fully DLCA methods, the improved dynamic matrix method and the method of applying the DyPLCA tools are more mature in terms of theoretical development of the methods, and the simplified DLCA method is more suitable for application. In order to achieve a standardized application of the methodology, new standards should be developed step by step: a calendar-based time range should be described and appropriate rounding rules should be introduced, and data accessibility should be improved through research into methods of identifying time-sensitive data, as well as the collection of real-time monitoring data and the modification of database formats.
