Abstract
An off-line heat supply system has been developed to enable industrial exhaust heat transfer to the distant user with very little heat loss. In this paper, we developed a GIS-based decision support system to estimate the spatial distribution of exhaust heat generated from industrial plants. Using the support system we evaluated CO2 emission reduction by introducing an off-line heat supply system in the Keihin industrial waterfront area, Kanagawa prefecture. The result showed that an off-line supply system of exhaust heat would reduce CO2 emission by 12%, compared with an on-line supply system.
