Daiwa House Industry Central Laboratory

Models and images of symbiosis housing from around the world are displayed on this floor. There is much to be learned from ancient civilizations who lived in harmony with nature.

Rock-hewn Houses (Cappadocia, Turkey)

Creation of human and nature

There is a forest of spiry-shaped outcroppings in Cappadocia due to fierce erosion by wind and glaciers. As they are made of tuff which is soft and easy to carve, people used to dig out caves and lived in these spiries. The air temperature inside is kept stable throughout the year despite the dry summer and cold winter of the area.

Old Japanese Farm House (Iya region, Tokushima, Japan)

Comfortable house throughout the four seasons

Thatched roof and clay walls which have good insulation and thermal storage are used to build this type of house. They keep the humidity and temperature inside comfortable throughout the year despite the hot and humid climate and the heavy rainfall of the area. The large canopies and bamboo roller blinds shut out the sunlight, and the big windows help the natural draft during the summer. Sources of heat during the winter are plenty of sunlight from the windows and the radiant heat from hearths.

Cliff Dwellings "Pueblo" (Colorado, America)

Solar house in natural cave

Pueblo is the dwelling of Native Americans known as Anazasi, which are caves dug into the cliffs. Adobe bricks that have good insulation and thermal storage are used for exterior walls, which shut out the strong sunlight during the day and give off heat at night. They also protect the inhabitants from enemy attacks and strong winds.

Round Housing complex (Fujian, China)

Housing complex durable against natural disaster

At the beginning of 18th century, the Hakka migrated to a mountainous area and built round Housing complexes. The walls protected the family from enemy attacks and from typhoons.

House with ventilator windows (Southeast of Pakistan)

House with handmade air conditioning

As summer is fiercely hot in the semiarid climate of this area, people have long been using handmade "wind scopes" on the roofs. They are made with cement and boards to draw the air into the rooms from the natural winds which blows from the same direction throughout a year.
