Abstract
This study describes the construction and evaluation of a low energy house which should be in harmony with the environment, assisted by hybrid natural energy resources as well as supplied by unused energy. An experimental house with ground source heat pump (GSHP) was built at Hokkaido University, Japan in March, 1997. As a result of experiments, it was shown that approximately 80% of the total energy was provided from photovoltaic (PV) modules, solar collectors, underground and exhaust heat. The annual energy consumption was 12.5% of a typical house in Hokkaido.
