I started the sale Smart Town Daiwa House Industry redevelop the elementary school site of the Sakai City, equipped in all building lithium-ion batteries and solar cells. Housing half in triple battery.
There is also a fuel cell, which further enhance the energy self-sufficiency. Energy self-sufficiency rate from April to June this year reached 89 percent. In consideration to the landscape, was buried in the ground wires.
■ The "visualization" the power consumptionThe total project cost 16,754 square meters of land area in the 2.5 billion yen. In order to be adopted Ministry of Land, Infrastructure and Transport has public offering in 2012 to the "first time housing and buildings reduce CO2 emissions leading business", subsidies Sakai also came out, cost incremental, such as storage batteries and solar cells that could be mostly offset . The draw internet access in all houses, each has to be able to check the power usage in the HEMS (home energy management system).
Can be expected energy-saving effect of power consumption in "visualization". Average price of 44 million yen in the spec house is all.
Solar cells made by Sharp in all relationships that large factory of Sharp to Sakai. Battery adopted the lithium-ion battery (Shinagawa, Tokyo) Erie power Daiwa House is invested. I have adopted the positive electrode of lithium iron phosphate that is difficult to ignite, explode against shock or short overcharge, from the outside.
Put in place a road in the direction the wind is likely as the purpose of increasing the efficiency of the air conditioning, and fitted with a screen to block strong sunshine on the outside of the sash. Wall to the high heat-insulated residential par in the Tohoku region, incorporating into the room by receiving the outdoor wind "vertical sliding window" also attached. I was in standard equipment also charging outlet and electric vehicles tank for storing rainwater.
when each and homes to power sales to the Kansai Electric Power surplus power, there is a mechanism that you have and features a rechargeable battery, reduce the purchase price. It's purpose is to avoid the criticism that injustice to be able to electric power sales in the higher price during the day, the electricity was accumulated in the night cheap electricity bill. Is provided with a mechanism that does not discharge the amount of electricity to greater than the degree of constant, and negotiated with Kepco depression of the purchase price so as not to cause a Harumidai.
■ The production and sale of renewable energy
In "The Third Wave" book, Alvin Toffler One of the foundation of the "Third Wave" to visit Next "wave of the first" and "second wave" with the advent of industrial civilization by the agricultural revolution It was pointed out that given the "renewable energy resources" in the new economy appeared under the Third Wave, "prosumer (producer consumer)" will increase.
Power companies to produce electric energy so far, I've been consumed consumers buy this.
But by the start of the feed-in tariffs, as well as buy the electricity, consumers became a prosumer to sell to the power company that produces renewable energy.
Yanbe Kimio director of the Energy Institute for Strategic Studies said, "prosumer sensitive to energy problems, load on the environment is to devise a small way of life, to choose environmentally friendly products even if a bit expensive" he said. Select the Smart House as prosumer exactly, residents of Harumidai is to devise an optimal use.
■ I aim EV utilization rate up
By the solar cells on the roof of the meeting place and adjust the pond, I have a large storage battery. I want to charge electric vehicle car-sharing for even (EV).
There is a storage capacity of 38.7 kwh The combined EV and meeting place. I live a toilet electric lighting and meeting place, and refrigerator power failure.
Miscalculation that utilization rate of car sharing for EV to be owned by the management association is low.
I was banking on the second car demand of residents, but households with two cars unexpectedly in many cases, use is sluggish. It is aimed at the utilization rate hike held the power-saving contest between residents, or issue a charge of EV charge point to high achiever.
There is also a fuel cell, which further enhance the energy self-sufficiency. Energy self-sufficiency rate from April to June this year reached 89 percent. In consideration to the landscape, was buried in the ground wires.

■ The production and sale of renewable energy
- Electricity consumption is reduced in the daytime absence of family to go to work or school. Part of the electricity that caused by the solar cells to self-consumption, but most turn to electricity sales.
- Because the battery that hoarding midnight power does not work, it does not boost the amount of electricity sold.
- Battery begins to discharge of a cheap electric solar cells without power is in the evening, when it comes a time when consumption of electricity increases, such as cooking.
- To reduce the electric bill to pay KEPCO as a result, lead to the maximum amount of electricity sold. Residents themselves devised Such use.
