Abstract: 'Low-level thermal energy' means energy used by the residential and commercial sector such as energy for heating, hot water supply and cooling. In this paper, the energy flow in the Osaka prefectural area, from energy supply, through energy consumption into waste heat discharge, is estimated by an integration method. The writers also evaluate the possibility of improving low-level thermal energy flow from the viewpoint of energy consumption and waste heat discharge. From the energy saving standpoint, utilisation of waste heat from the industrial sector is effective. Utilisation of heat source water by transportation networks has a smaller energy saving effect than waste heat. However, it has a large heat island prevention effect in the city centre.
