In green concept hospital work, several provisions must be obeyed so that all processes, including material selection, project implementation, and building operations, must refer to green principles. Green building planning and construction costs higher than conventional by 10-20%. By using the Value Engineering (VE) method and combined with the Lifecycle Cost Analysis (LCCA), the researcher applies the green hospital concept to a project which is a case study but is still cost-effective even lower than the original Bill of Quantity. To see the strong influence of effectiveness on the hospital project, the researcher distributed a questionnaire to stakeholders. The results of the questionnaire were processed and analyzed using the Statistics Products and Solution Services (SPSS) tool. VE is implemented after first creating a Function Analysis System Technique (FAST) diagram, before and after adding functions for certain work items. It turns out that the use of the VE and LCCA methods is very influential in improving cost performance. From the calculation of the VE method, the resulting costs are up to 2.62% of the initial cost and LCCA shows the payback period of the Solar Power Plant with time = 9.64 years ≈ 9 years 7 months. The novelty of this research is the selection materials and the green concept of working methods is still cost efficient and the installation of Photovoltaics (PV) on the roof of Hospital reaches a payback period which is feasible for new investment.
