Recently driven by the ease of remodeling and increase of lifespan and performances required of apartment houses, demands for plaster board drywall with outstanding flexibility are growing, and the importance of their assessment of environmental load is rising. In this study, $CO_2$ generated during the life cycle of a building($LCCO_2$) and its economic efficiency were evaluated for the assessment of the environmental load and cost of buildings that used plaster board drywall. Typical concrete bearing wall structure for apartment building was set as case 1, and comparison subjects were developed as case 2, case 3 and case 4 based on the ratio of plaster board drywall on top of case 1. Structural safety of each building to be assessed and the legal incentives by the use of variable type wall were considered. In addition, both for life cycle $CO_2$ emission and economic efficiency, life cycle assessments were conducted by stages including construction stage, operation/maintenance stage and demolition/waste stage. A set of data including construction material quantity, amount of energy usage, repair rate and repair period etc which are required in each stage of assessment were utilized for both $CO_2$ assessment and economic efficiency. As a result, in case of flat-type, the life cycle $CO_2$ reduction rates of cases 2, 3 and 4 compare to case1 were 1.0%, 4.5% and 5.4% respectively, and in the assessment of cost, the reduction rates compare to case1 were -0.01%, 5.8% and 6.0% respectively.

In this study, CO₂ generated during the life cycle of a building(LCC) economic efficiency were evaluated for the assessment of the cost of buildings that used plaster board drywall. Typical concrete bearing wall structure for flat-type apartment building was set as case 1, and comparison subjects were developed as case 2, case 3 and case 4 based on the ratio of plaster board drywall on top of case 1. In addition, using the building life cycle economic cost evaluation was conducted economic efficiency, life cycle assessments were conducted by stages including construction stage, operation/maintenance stage and waste stage. As a result, in case of flat-type, the CO₂ reduction rates of cases2, 3 and 4 compare to case1 were 0.001%, 5.8% and 6.0% respect.

GHG emission of building sector is focused on important issue because the emission amount is one quarter in total emission amount in Korea. In this study, program that is calculation tool of building GHG emission amount was developed to calculate building GHG emission though the building’s whole life cycle. In this study, program that is calculation tool of building GHG emission amount was developed to calculate building GHG emission though the building’s whole life cycle to prevent global warming. As the reason, GHG emission amount of building sector is one quarter in total GHG emission amount in Korea. For developing the program, the entire process for calculating GHG emissions of building was applied ISO 14040 standard that is international standards of life cycle assessment. In addition, conventional programs were researched for applying their characteristics to our program. Based on this, the program calculates building GHG emission through each of blinding life cycle stages that are materials product, building, management of construction and disposal/recycle. For providing convenience to user, the program has automatic function which is result of material amount through BIM program and energy consumption calculation program is imported to the program.
