Abstract
LCC (Life Cycle Cost) analysis is a practical method and a guideline for evaluating the economic performance of building service systems. By using the LCC analysis, the most cost-effective design decision can be made, which has the lowest LCC during the project study period among the various design alternatives. The present case shows an example of appropriate use of the LCC analysis, by demonstrating the procedures of decision-making among alternative building HVAC systems at Community Center and Congress Hall of a Local Government.
