Comparing the Standards of Life Cycle Carbon Assessment of Buildings: An Analysis of the Pros and Cons

Buildings play a substantial role in carbon emissions and contribute to approximately 37% of global emissions. In order control reduce the buildings, report life cycle assessment (LCCA) has been mandated for all new buildings China since 1 April 2022. As technical support accounting efforts China, it is important adhere national standards conducting an LCCA report. this context, GB/T51366-Standard Building Carbon Emission Calculation designated standard that should be followed. However, GB/T51366 several deficiencies, including incomplete processes, impractical calculation methods, unrepresentativeness default emission factors, so forth. Therefore, essential critically analyze pros cons employing methodology adhering GB/T51366. To fulfill research aim, study develops computational toolkit based on We propose two data collection methods conduct case residential building China. was also used as baseline scenario compared with European EN15978. The results show less comprehensive than EN15978, leading 2.9% reduction total Notably, up 26.7% difference observed comparison factors main construction materials. Based outcomes, suggested improve terms scope availability, well promote harmonization existing international standards.
