| Abstract |
The construction industry consumes lots of energy and its influence of environment is much worse than others. There were many studies before but not in building equipment field. However, the consumption of energy and the environmental load are important not only construction part but also building equipment field. We need to have the analysis which compared through the case building as well. We analyzed LCI (Life Cycle Inventory) and LCIA (Life Cycle Impact Assessment) with comparing ice thermal storage system and direct-fired absorption chiller-heater system in the stage of manufacture and use (except construction and disposal). This study shows you the ice thermal storage system's LCI emission is 10.5% lower than direct-fired absorption chiller-heater system's and the ice thermal storage system's LCIA is 15.7% lower than direct-fired absorption chiller-heater system. It means ice thermal storage system is more environment-friendly than direct-fired absorption chiller-heater system. |
