Abstract

This paper is investigating the CO2 emission saving of ground source heat pump (GSHP) systems for providing heating comfort condition for the residential buildings in cold climate of Japan. After presenting the data related to space heating energy consumption in Japan and also the concept of GSHP system, the required energy and equivalent CO2 emission of heating system for a sample building in Sapporo City were calculated in 3 scenarios: GSHP system, air-source heat pump (ASHP) system and kerosene heaters. Results of the calculations showed that the energy consumption and CO2 emission in the GSHP system is lower than the other scenarios. The CO2 emission in the kerosene scenario was 45% and 36% higher than GSHP and ASHP scenarios, respectively.
