Abstract :The concept of green buildings or green buildings is highly needed in the present era, considering the drastic decline in global climate conditions. However, its development is greatly hindered because the implementation of green building concepts is primarily focused on new constructions, while almost two-thirds of the world\'s buildings are already built. Therefore, the objective of this research is to enhance the Performance of Green Retrofitting Implementation Time, which is expected to accelerate the growth of existing green buildings in Indonesia by identifying the Procurement and Permitting Processes of Green Retrofitting in High-Rise Office Buildings in Jakarta based on PERMEN PU NO 21 TAHUN 2021 (Regulation of the Minister of Public Works and Housing Number 21 of 2021) and Green Building Council Indonesia (GBCI) through work breakdown structure (WBS) along with their high-risk activities and improvement strategies using a preventive approach that Influences the Performance of Green Retrofitting implementation time. This research analysis involves 15 respondents\' data on risks in the procurement and permitting processes, which will be processed using a qualitative risk approach. Based on the results of literature studies, expert validation, and respondent questionnaires, a total of 83 activities in the procurement and permitting processes of green retrofitting were identified, 214 risk indicators that affect the performance of green retrofitting schedule, along with 56 prevention strategies for the high-risk situation, aiming to accelerate the growth of existing green buildings in Indonesia.
