Aomori Prefecture where I live in was suffered badly from the Great East Japan Earthquake on March 11,2011. I have been plannning this house to encourage Tohoku people taking 3 years since the disaster. The disaster made me desire to build a house which encourages people in Tohoku district. It took 3 years to complete this plan.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
We call this house "A house without heating systems and Japanese style doma". This is a house composed of "doma", traditional Japanese entrance space, and the residential space doesn't requre heating system. I have planned the "somewhat nostalgic and futuristic house", combining the Japanese-style traditional doma and the no-heater-requiring space. The doma space is half outdoor and half indoor space, while other space doesn't requir heating system by adopting super thermal insulation.
OPERATION / FLOW / INTERACTION:
I have visited Fukushima so many times to see the real situation and recognized how seriously they are affected by the catastrophe of the Fukushima Daiichi nuclear power plant. Even though my contribution might be small for that, I have been pondering about the house utilizing natural and human body heart.
PROJECT DURATION AND LOCATION:
The project started in april 2012 and finished in April 2015 in Aomori Prefecture, Japan.
FITS BEST INTO CATEGORY:
Architecture, Building and Structure Design
PRODUCTION / REALIZATION TECHNOLOGY:
I adopted thick wall learning from "Kura", Japanese traditional storehouse, to protect family and possessions because the structure enables the house to heat air by nature and body heat, and home electric appliances.
SPECIFICATIONS / TECHNICAL PROPERTIES:
Allocating one-third of the ground floor for doma, laid out endai, Japanese traditional benches, irori, Japanese traditional inner fireplace, and ofuro,bathing space with wooden bath tub. The residents can enjoy their meal, sitting by the irori. While the wall of doma has 100mm as thick as usual Japanese house, that of residential space has 340mm for insulation which has significant performance with Q-Value 0.49. Thanks to this wall, this house requires almost no fuel and electricity expenses.
House, without, Heating, Systems, Japanese, style, Doma
Our area is in the frigid zone and its temperatures sometimes drop to minus 20 degrees in the winter season. However, inside no-heater-requiring space of this house, the temperature is controlled around plus 20 degrees even in the winter, without turning on heating. It becomes warm by the natural sunlight and human temperature.The wind comes in through the entrance space, and it is comfortable in summer, since residents can water onto the floor . This is the house where people can live very comfortably throughout four seasons.
I always thought that I wanted to build a Passive House which could provide warmth and heat using natural energy for the residents of the Tohoku district after the East Japan great earthquake disaster of March 11, 2011. So I examined the house generated only by the natural power, without depending on machines as possible. I hope this project would be helpful for the people in the Tohoku district.
