Building houses with straw - ideal for the environment, economically efficient

Build houses, schools, even offices with straw walls that are not water-proof, fire-retardant, secure internal energy, and can resist thunderstorms, useful for the environment. That is the conclusion of a group of architects who are piloting the construction of rice straw houses in US states.

The houses of this type often have walls about 60 cm thick, though more expensive than the cost of cement and wood, but very cool, saving a lot of costs for heating in winter and regulating in season summer.

Some design experts have determined that the use of rice straw as a building material is ' ideal' in the policy of building ' green buildings ', because it does not only handle a quantity of waste. giants in the agricultural sector but also contribute to saving energy for the whole society.

The international organization that registered to build houses with straw bundles said that there are 538 registered straw-building projects all over the country, some of which are in the area around Washington Capital. city.

Building straw walls, reinforced with mortar, is not a new idea because since the late 1980s, farmers in some of the non-vegetation areas of Nebraska used straw and Hay to build tents right on their farms.
