FTUI Doctor Proposes Cost-Efficiency Solutions for Carbon Emission Reduction in High-Rise Office Buildings<\/strong><\/p>\n

On Friday (10\/01), Bernadette Detty Kusumardianadewi, a doctoral candidate from the Department of Civil Engineering at the Faculty of Engineering, Universitas Indonesia (DTS FTUI), presented her research on a cost estimation model for green retrofitting of high-rise office buildings during her doctoral defence in the Smart Meeting Room, Dean\u2019s Building. Detty\u2019s dissertation, titled Cost Estimation Model for Green Retrofitting Based on PERMEN PUPR No.21\/2021 and GBCI Guidelines in High-Rise Office Buildings Integrated with WBS, BIM-5D, and Information Systems to Improve Cost Accuracy,<\/em> highlighted innovative methods for reducing implementation costs.<\/p>\n

Detty observed that green retrofitting, which aims to reduce carbon emissions, has become a key focus in the construction sector. With buildings contributing up to 37% of global carbon emissions, implementing green retrofitting in existing structures is crucial. However, limited incentives and high implementation costs\u2014estimated at S$58.27\/m\u00b2\u2014remain significant barriers for property owners.<\/p>\n

The research aimed to analyze the performance of existing office buildings in improving their green performance using Work Breakdown Structure (WBS) estimation theory and risk management. It also aimed to develop a certification process through assessments supported by information systems.<\/p>\n

The study facilitated the evaluation of green retrofitting integration guidelines using a web-based information system. The Building Information Modeling (BIM-5D) Quantity Take-Off method was also employed to enhance cost accuracy. The research resulted in Green Retrofitting Integration Guidelines,<\/em> supported by statistical analysis using SEM-PLS, which identified 10 key influencing factors. These included the Planning Stage, WBS Risks, Quantity Extraction, Information System Content, Web Utilization, Cost Estimate Classification, Cost Accuracy, and the relationship model between cost estimation and accuracy.<\/p>\n

\u201cThis study offers practical solutions for building owners to address the cost challenges of green retrofitting. Building owners can feel more confident investing in environmentally friendly retrofit projects with accurate cost estimation models. Implementing green retrofitting provides economic benefits and contributes to the global effort to reduce carbon emissions,\u201d Detty explained.<\/p>\n

The Acting Dean of FTUI, Prof. Ir. Mahmud Sudibandriyo, MSc., Ph.D., remarked, \u201cThis research significantly contributes to reducing carbon emissions in the building sector, which currently accounts for approximately 37% of total global carbon emissions. I commend the researcher\u2019s efforts in developing a model applicable to major cities in Indonesia. Furthermore, the model developed in this dissertation can improve cost and time efficiency for green retrofitting projects. The Faculty of Engineering UI hopes this research becomes a reference for policymakers and construction industry players in implementing green building standards.\u201d<\/p>\n

Through her research, Bernadette Detty Kusumardianadewi earned her doctoral degree with a GPA of 3.9 and the distinction of Cum Laude.<\/em> She is the 76th doctoral graduate from the Department of Civil Engineering and the 586th from FTUI.<\/p>\n

The doctoral defense was chaired by Prof. Dr. Ir. Yanuar, M.Eng., M.Sc., with Prof. Dr. Ir. Yusuf Latief, M.T., serving as the supervisor and Prof. Dr. Ir. Tommy Ilyas, M.Eng., and Ayomi Dita Rarasati, S.T., M.T., Ph.D., as co-supervisors. The examination committee included Prof. Ir. Widjojo Adi Prakoso, M.Sc., Ph.D., Prof. Mohammed Ali Berawi, M.Eng.Sc., Prof. Ir. M. Agung Wibowo, M.M., M.Sc., Ph.D., Leni Sagita Riantini, S.T., M.T., Ph.D., and Dr. Van Basten, S.T., M.T., MBA.<\/p>\n
