| Abstract |
Remodelling is a more effective method than the new construction in utilizing the building resources and dealing with the construction waste. Recently, the government housing policy has a little changed into remodelling because rebuilding or rehabilitation has many problems such as social gap, real estate price inflation and provision of infrastructures. Remodeling is mostly conducted at the end of building lifetime on which is decided with rebuilding or remodelling of building. On the other hand, it needs to assess the relation between the environmental affects and remodelling works. It is possible to control the elements which too much affect the environment through the results of this work. In this paper, it analyzed the embodied energy consumption, CO2 emission and SOx emission in remodelling the multifamily housing, using the indirect estimation of the input-output analysis in aspect of the building works and materials & components inputted into remodeling construction. The results are as follows ; First, the building work occupied about 70% over in the total energy consumption, CO2 emission and SOx emission. The building work has a higher ratio than any other mechanical works and electrical works. Second, The product including the cement occupied higher ratio than any other materials and components in energy consumption, CO2 emission and SOx emission. |
