Abstract

![CDATA[Material selection is one of the significant tasks in building construction. In this process cost is one of the vital components considered. However, apart from the initial cost, many other costs occur within the life-cycle of the building that is ignored in the initial decision making stage. Therefore, the life-cycle costing approach must be considered to make informed decisions from the beginning. This research focused on using life cycle costing as a technique to identify optimum solutions for insulated floors commonly used in six central business districts (CBD) in Australia. Various insulation material was considered to arrive at the required R-values measured in m2K/W. Net present value technique (NPV) was used to arrive at the life-cycle cost of floor solutions. Suspended slab with vapour permeable membrane floor solution has the lowest life-cycle solution, and it also satisfied the required R-Value. Costs other than the initial cost vary from 35% to 59% of the life-cycle cost in floor structures. This significant percentage illustrates the importance of using life-cycle cost for evaluating various options focusing on all the associated costs.]]
