Abstract:With the deepening of the "dual carbon" goal, the construction and decoration industry urgently needs to promote green transformation. The article combines three typical project cases to conduct a systematic analysis from four dimensions: green material and component selection, prefabricated dry construction technology, BIM technology collaborative management, and fine control of construction environment. Based on actual project data, the comprehensive benefits of green construction technology are verified, aiming to provide replicable and promotable technical references for green construction practices in similar decoration projects.
