If the planning is proposed, a good ecological circle can be constructed by connecting various industries such as energy, education, industry and commerce, sightseeing agriculture, breeding industry and the like, and the building is suitable for living, industry and health maintenance, so that the laggard traditional building is gradually eliminated.

Specifically, as shown in fig. 1 to 7, the energy-saving building comprises a building body 1, and is further provided with a public outer wall 2 surrounding the building body 1, the top of the public outer wall 2 is provided with a dome 3, the dome 3 is connected with the top of the building body 1, the dome 3 is provided with lighting glass 4, the lighting glass 4 is provided with an exhaust port 5, an exhaust fan 6 is arranged at the exhaust port 5, and the dome 3 and the public outer wall 2 form a closed space for covering the building body 1; the bottom of the public outer wall 2 is provided with a longitudinal passage opening 7, and the closed space is communicated with the outside through the longitudinal passage opening 7; the bottom of the building body 1 is provided with an inlet communicated with the closed space.

It should be noted that the enclosed space is not a sealed space, and the upper portion has an exhaust port, and the lower portion has an air inlet channel, so as to mainly reduce the direct entry of the external cold and hot air flow into the building. The longitudinal channel opening 7 is mainly used for air intake and can also serve as a passage for people and vehicles to enter and exit. In this particular embodiment, the longitudinal passage opening 7 is arranged underground. The dome 3 is constructed by adopting a steel structure, a steel framework made of the steel structure is directly fixed at the top of the building body 1, and glass is arranged on the steel framework; the dome 3 can cover the top of the building body 1, the whole design is convenient for construction, and the supporting force of a steel skeleton is improved; the dome 3 can also be built along the edge of the top of the building body 1, and the steel skeleton is fixed on the edge of the top of the building body 1, so that the design is favorable for reducing the cost and is convenient for popularization and use. The air outlet 5 is provided with a shelter to prevent rainwater from entering the interior of the building. Specifically, the side-open glass shed 14 is installed in the air outlet 5, as in the dome 3, to prevent rainwater from entering the building. In this embodiment, the public outer wall 2 may be made of full glass, so that the lighting is better, and the part of the house near the public outer wall 2 may also be retained with the window shared by the public outer wall 2. In other embodiments, the public exterior wall 2 may also be a brick and concrete structure. The public outer wall 2 can also be a glass curtain wall arranged between the building bodies 1, and the reconstruction cost of the building can be reduced in the subsequent popularization. The shape of the public outer wall 2 can be rectangular, circular or irregular, and the building body 1 can be a single building or a building group.

By establishing the public outer wall 2, cold and hot air flows of the external environment can be resisted, the cold and hot air flows are prevented from directly entering the interior of a building, a longitudinal channel opening 7 is arranged at the bottom of the public outer wall 2, and the air flows from bottom to top are generated in a closed space by utilizing the principles of cold air sinking and hot air floating; when the number of the building bodies 1 is more than one, in the closed space, the gaps among the building bodies can play a role of partitioning the closed space, and the building bodies 1 are communicated at the bottom through inlets, so that the cold and heat complementation of each area can be realized. In order to increase the flowing speed, an exhaust fan 6 is arranged at the exhaust port 5 of the dome 3, so that the external cold and hot air can enter the public outer wall 2 from the longitudinal passage port 7 and is finally exhausted from the exhaust port 5, the airflow entering the public outer wall 2 forms a sequential flow from bottom to top, and the air inside the building keeps fresh and smooth. Just because the longitudinal passage opening 7 is underground, the heat exchange with the external environment is less, the temperature difference change of the external environment is fast, and the temperature difference change of the underground is slow, therefore, the temperature of the air flow passing through the longitudinal passage opening 7 is lower than that of the external air flow in summer, and the temperature of the air flow passing through the longitudinal passage opening 7 is higher than that of the external air flow in winter, so that even if auxiliary temperature adjusting equipment such as refrigeration and heating and the like is not used in the closed space formed by the public outer wall 2 and the dome 3, the effect of being warm in winter and cool in summer can be achieved in regions with moderate temperature compared with the traditional open-type building, the building is more suitable for residents, and the lighting glass 4 on the dome.
