This systematic review maps carbon credits in major Green Building Rating Systems (GBRS) by life-cycle stage, finding that operational carbon is prioritized while embodied carbon is underrepresented. Only DGNB allocates over 50% of carbon c…

Samson Femi Adesope, Klaudia Zwolińska-Glądys, A. Ostręga +1

This study proposes an integrated BIM-LCA framework to quantify embodied carbon in regenerative building design. Results show that material extraction, processing, and manufacturing contribute over 85% of total CO2 emissions. Sensitivity an…
