Development of HVAC system simulation tool for cycle energy management- Part 3:case studies using developed tool on each phase of life cycle

The HVAC system in a real building was simulated by the energy simulation tool being developed (Ito et al. 2007, Sugihara et al. 2007). In order to confirm the practical utility of the tool, the studies are conducted on each phase: Program/Planning/ Design  phase, Construction phase, Pilot-Operation phase and Operation phase. The tool was used to simulate from small systems such as simple equipment to total HVAC systems and might have applicability to fault detection and maintenance management. In this paper, first the phases in a lifecycle and evaluation index of air-conditioning system in a life cycle are discussed. How the developed tool was used on each stage is also discussed. Then the case study in which applications of simulation by the developed tool are demonstrated was conducted.
