| Abstract |
The types of buildings have been diversified and the size of a building has been growing according to the development of human society and technology. Unfortunately, high-rise buildings consume enormous resources and energy not only at their construction stage, but also for their operations and maintenances. Therefore, it is very important to select an efficient plan from the early design stage for reducing resource usages and saving energy. Life Cycle Cost Analysis (LCCA), a method, in which construction costs as well as operation and associated costs are considered, is useful as an economic evaluation method. However, alternative evaluation of building service systems has been a quite difficult work in practice, since important variables for the analysis such as cost data, especially operation cost data were almost inaccessible and a proper way to prepare those data has not been established. In the present work, important analysis variables and cost data for LCCA are prepared and presented, which can be used for designers to carry out an economic evaluation of alternatives for building service systems. It would be possible for a designer to perform an economic evaluation of alternatives and system integration with the process and data proposed in this study. However, for more exact and various evaluation and its practical application, further studies on LCCA with extensive operation cost data are expected and required. |
