| Abstract |
This study is to establish the database that could be applied to the building LCA. Firstly,??the methodologies of building LCA and energy based I/O model for estimating embodied energy of building materials were examined. Then, the intensity of energy consumption and CO2 emission for building materials and construction stage were estimated. The intensity D/B for building materials calculated by the 2000 I/O table was compared with the D/B by the 1995 I/O table. According to the result of comparison, there were a little differences between the results calculated by the new and the previous data, and two results showed nearly the same patterns. So, it could be said that the industrial activity change has little effect on the intensity of building materials during the past 5 years. For the calculation of the intensity in the construction stages, the payment documents of an oil and electricity consumptions during construction for the sample buildings were surveyed and the intensity per a building gross area were calculated. The D/B presented in this paper could be applied to the building LCA proces as the basic data for analysing global worming effect caused by building construction. |
