Low-energy-consumption green building

The invention provides a low-energy-consumption green building, which relates to the technical field of new energy buildings. The method of the product is characterized in that solar energy and geothermal energy are fully utilized so as to enable the interior of the building to maintain constant temperature, wherein solar energy is utilized for generating electricity, and geothermal energy is used for heating and refrigerating the building; the power of a geothermal system comes from electricity generated by solar energy; the geothermal system adopts a floor radiating manner, radiating tubes are arranged in a floor, so that the whole floor becomes a large radiator, the building adopts a totally-closed structure, and windows adopt closed heat-insulating windows. The building can achieve effects of energy saving and emission reduction by utilizing a green energy source comprising geothermal energy and solar energy, and energy consumption can be reduced by over 90%. Meanwhile, an intelligent air circulating system is used, indoor air is fresh all the time, and the floor radiating manner is adopted, so that an air-conditioning system is not used in a room, and accordingly, a human body can be in an optimum comfortable state all the time.
