The New Energy and Industrial Technology Development Organization (NEDO) announced on November 15, 2011, that Shinshu University and Shimizu Corp., a major Japanese construction company, completed construction and started operation of demonstration facilities for testing a high-efficiency heat-pump system that uses groundwater as a heat source. The new facilities are part of a larger NEDO project focusing on next-generation heat-pump research and development. The new system is expected to demonstrate higher efficiency than conventional "multi-type" air-conditioning systems used in buildings.

The new system, developed to reduce the energy consumption of air-conditioning systems, involves a water-cooled heat-pump system that uses groundwater as the heat source and operates more efficiently by utilizing groundwater temperatures. The efficiency and reliability of the system will be verified through the testing.

Air conditioning and hot-water supply accounts for about 55 percent of household energy consumption and about 40 percent in workplaces out of the total energy consumption in the non-industrial sector, strongly underlining the need to reduce energy consumption in this area.
