Energy-saving building equipment based on BIM (Building Information Modeling) and use method thereof

The BIM-based energy-saving building equipment comprises a fixed box, a plurality of mounting frames are mounted on the outer side wall surface of the fixed box, first hydraulic cylinders are mounted on the lower wall surfaces of the mounting frames, and first driving parts are mounted at the telescopic ends of the first hydraulic cylinders; the device has the beneficial effects that firstly, a carrying piece is aligned to clamp a ventilator, then a connector is locked to fix a building wallboard body, when the device moves, the carrying piece is aligned to work, the ventilator is made to move, when an identification camera identifies that the ventilator is aligned to a threaded hole, an air cylinder extends, and the ventilator is driven to move. And the fourth driving piece works and drives the ventilator to extend into the threaded hole, the fourth driving piece is matched with the air cylinder, assembling of the energy-saving building ventilation wallboard is completed, the operation time is saved, the ope
