Comparativo de custos de um edifício de alto padrão com e sem a certificação GBC (Green Building Council)

Abstract

With the increasing concern for the environment and the construction industry being one of the main polluting agents, sustainable certifications have emerged as a tool for implementing measures to address these issues. This study presents a comparative cost assessment for the implementation of the Green Building Council certification in a building. The results show that the certification led to a 10.71% increase in the total construction cost, exceeding R$1,000,000. The superstructure service had the most significant impact, accounting for 64.94% of the cost increase due to the requirements of the certification. Other services, such as sunshade installation (12.43%) and glass (8.05%), had a smaller contribution. Despite analyzing the certification's requirements, the changes made are practices that should already be common in constructions and are already specified in regulatory project standards, ultimately leading to enhanced user comfort. This highlights the importance of adopting sustainable certifications, like the Green Building Council, to address environmental concerns and promote responsible construction practices.
