The invention relates to an ecological energy complex building. The ecological energy complex building comprises a building body, doors and windows, a building roof and guardrails, wherein a concrete reinforcement layer is poured on the building roof; and fertile soil is transferred to the building roof, and moist soil is quickly dried through sunshine and air flow, so that fertilizer elements ofthe soil are improved, bacteria and parasites in the soil are killed, and the ground is not intruded by harmful insects and jackals such as mice, mosquitoes, flies and the like. In the ecological energy complex building, the problem that farm land is reduced due to construction is solved, abandoned land is changed into fertile farmland for planting, and water and soil loss and fertile soil loss are reduced; the ecological energy complex building has a protective effect on crop growth periods by using solar energy, and ensures that crops are not damaged by typhoon, hail, storm or influenced byclimate environment; the crops can be planted in all seasons, a harmonious effect of urban area climate is maintained, planting areas have an effect of protecting natural environment, and living conditions are improved; power is generated by using new energy such as wind, rain and water to be supplied to the building, so that the independent development cost of wind power generation is greatly lowered; the defects of tension supply of natural gas, liquefied gas and electric power and underutilization of methane, solar energy and geothermal energy are overcome; and environment-friendly and low-carbon life is realized.
