Recently, the environmental conservation has been emphasized over the world. Building industry should carefully reflected the development focused on the economic aspect as well as the environmental considerations. Therefore, it requires the technology development to mitigate the environmental pollution through the reducement of the energy and resources usage amount over the building life cycle. For these, it should be required to set up the analysis methodology to grasp the amount of the environmental pollution and energy and resources in each step of building life cycle. In this paper, it aimed at preparing the analysis process and analyzing the embodied energy and $CO_2$ and $SO_x$ emission according to the building work, field work, mechanical and electrical work on the new building and remodelling, utilizing the inventory analysis which is one of the LCA process.
