The invention discloses an environment-friendly house and aims at solving problems that the exiting house cannot achieve warm in winter and cool in summer indoors, self power supply or sufficient rain utilization. The environment-friendly house comprises walls, a roof arranged on the upper portions of the walls and a door arranged on the walls. The walls are formed by light-transmitting inner
layers and outer
layers, temperature adjustment
layers are arranged between the inner layers and the outer layers of the walls, a
natural power generation device is arranged on the roof, and rain collection tanks are arranged on the roof and the periphery of the walls. The environment-friendly house achieves warm in winter and cool in summer indoors through the temperature adjustment layers; the glass walls are good in lighting performance, avoid lighting up indoors at the
daytime and save
electricity; the environment-friendly house generates power by sufficiently utilizing wind energy and
solar energy and achieves self power supply of the whole house; domestic water is supplied indoors by collecting and purifying rain; waste water of the temperature adjustment layers can be collected into a waste water tank to be used for watering flowers, plants can be planted on the roof, and therefore the environment is beautified and the house attractiveness is enhanced.
