Since the March 11 crisis, Japanese citizens have taken a great interest in energy issues, and the Japanese government has taken various actions to promote the introduction of a renewable energy system. One such action is the focus on ground source heat pump systems. The GSHP market is growing by 20 % a year and GSHPs have been planned in many NZEB projects in recent years. This paper reports on the current status of the Japanese GSHP market and shows an example of NZEB integrated with renewable energy resources, including a GSHP for the floor heating system in a cold region.
