ABSTRACT
Basically, the building cost is based on all stages of a project integrated from preliminary development to construction excluding the cost of maintenance and operation. But, to estimate the overall building life-cycle cost, the maintenance and operation costs must be included for a total economic building management. Accordingly, the integration of the overall building cost requires a methodology for the optimization of building project cost based on life-cycle cost. In this paper, we propose such a methodology for determining the optimal alternative floor plan of high-rise apartments.
