Energy management is now a global focus due to its negative environmental impacts, yet its demand will persist due to the acceleration of economic growth especially in construction industry. A key component influencing energy consumption is the building envelope, which subsequently affects construction costs, as well as operational and maintenance expenses. This research aims to provide a solution by evaluating building envelope designs and lifecycle cost efficiency through the integration of Building Information Modeling (BIM) and Life Cycle Cost Analysis (LCCA) in a case study of The Turyapada Tower Project. Stands at 1.701 m above sea level, this project is on a hill within Bali’s Conservation Area Forest. By utilizing 3D model with LOD-300, this research compares the Overall Thermal Transfer Value (OTTV) from conventional calculations with a BIM approach to select materials with their energy performance and lifecycle costs. The lifecycle cost calculations using the Net Present Value (NPV) approach to assess initial expenditure and associated future costs. The results show that this computational method provides a stronger foundation for determining the most effective energy consumption. It confirms the necessity of incorporating lifecycle cost analysis, especially in terms of energy used and construction costs into architectural design to achieve sustainability goals.
