Daiwa House Industry Co Ltd has built a disaster-resistant house featuring an innovative all-weather, three battery linking system.
The house which is resistant to primary and secondary disasters, can supply itself with electricity, heating and hot water for about 10 days even when it is raining.
The ‘All-Weather Three Battery Linking System’ is composed of a solar power generation (PV) system, an Ene Farm fuel-cell cogeneration system, and a residential Li-ion storage battery.
Daiwa House developed a ‘cross board’ to link all the three kinds of power sources together.
The cross board uses electricity generated by the Ene Farm in the house at the time of a long-term power outage or stores it in the storage battery.
At normal times, fuel and light expenses can be reduced by about 84.2%, thanks to the electricity generated by the Ene Farm and PV system.
House owners can also select a solar panel from products of multiple manufacturers.
For instance, the Ene Farm system is a product of Panasonic Corp, and the storage battery is a product of Eliiy Power Co Ltd.
The house comes with the newly-developed ‘KyureK’ load-bearing wall that can reduce the shaking of building by up to 50%, compared with Daiwa House’s existing detached houses.
It features a ‘Rooga’ disaster-prevention roof tile, which absorbs impacts caused by flying objects at the time of violent wind such as typhoon and prevents damages.
The house also has a ‘Disaster-prevention, Crime-prevention Glass,’ which doubles the thickness of the intermediate layer of laminated glass.
