Conceptual model for LCC-based LCCO2 analysis of apartment buildings

Abstract

Currently, the construction industry generates more CO2 emissions than any other industry in Korea. If carbon taxes are imposed on the resources after 2015 in Korea, there will be a sharp increase in total construction costs. Therefore, new construction methods and management to reduce CO2 emissions with minimized input of energy and resources are necessary. However, few studies have been conducted CO2 and concerning cost management during the lifecycle of buildings. The objective of this study is to develop a conceptual model of life cycle cost (LCC)-based life cycle CO2 (LCCO2) analysis. The model consists of 5 subsystems, such as LCC, LCCO2, cost-carbon effect and energy analysis system including decision-making support system. This study focuses on the apartment buildings which compose more than 60% of housing units in Korea. The cost-carbon effect can be analyzed easily and quickly in the optimized manner by using the model. The model helps to plan for green construction and process management of apartment buildings.
