Builders' Network Launches Zero Utility Cost Housing

Keywords: Energy Conservation Environmental Technology Manufacturing industry 

Japan Area Home Builders' Network (JAHB Net), a network of about 600 builders and construction companies in Japan (headquartered at Aqura Home), issued a release on April 20, 2005 describing a standardized house that achieves zero utility costs through combining a photovoltaic (PV) power generation system with all electric appliances.

Called Hyugazero, the house, highly insulated and totally electrified, is equipped with a high-efficiency PV generation system (5.76kw). The income from trading surplus electricity surpasses the costs of grid electricity used, reducing annual utility costs to zero. The network says that it will be possible to cut utility costs by about 5,920,000 yen (about U.S.$ 54,000) over 30 years.

In addition, an "Eco Cute" heat pump water heater that effectively uses heat in the air to heat water is standard equipment for the house. Using cheaper off-peak power, Eco Cute is expected to lower running costs to about one sixth the cost of using a gas boiler.

Aided by partnership agreements, any member of the network can offer PV generation, electrification and next-generation energy-efficient housing. JAHB Net has also succeeded in lowering its construction costs through purchasing large-lot materials, concentrating sales promotion campaigns within short periods, eliminating the subcontractor system, and using joint advertisement.
