ENERGY CONSUMPTION AND CO_2 EMISSION DUE TO CONSTRUCTION OF DISTRICT PIPING

Abstract

Basic sector classification input/output table were applied to analyze the construction cost of three types of district piping in DHC in order to obtain the energy consumption and CO_2 emission. The analyzed three types of district piping are a) open-cut method, b) jacking method and c) directly-buried method. The values of final energy consumption are 6.5〜11.2 GJ/m・m^2 for a) and b) method, and 3.1 GJ/m・m^2 for c) method. The amount of CO_2 emission are 0.60〜0.96 t/m・m^2 for a) and b) method, and 0.27 t/m・m^2 for c) method.
