abstract
Life cycle cost and effects of district heating and cooling system(DHC) in 23 wards of Tokyo using thermal energy of sewer water, river water and groundwater is quantified in terms of cycle energy(LCE), life cycle CO2 emission(LCCO2) and life cycle cost(LCC). The effect of reducing CO2 and NOx emission, and cooling water is also evaluated as monetary benefit. All these indices are compared among three scenarios of DHC using water resources(case A, B and C) and a case of without DHC. LCC is estimated to be minimum for case B, while LCE and LCCO2 decrease as the dependency of DHC on the water energy is high.
