Premanufactured structures for constructing buildings comprise a construction system for an energy efficient multi-story building with standard single or mixed units. The multi-story building is constructed using premanufactured structures: non-weight bearing walls with finished exterior including all electrical, insulating, plumbing and communications components that are premanufactured at a site distant from a building site, and the non-weight bearings walls are attached to a floor and ceiling slabs, interfacing with each other to enclose units of the building; interior components that are premanufactured at a remote site to connect to inside portions of the non-weight bearing walls; and exterior components that are premanufactured at the remote site to attach to exterior surfaces of the building. Non-weight bearing walls, interior components, and exterior components are installed and connected together to provide the energy efficient multi-story building with units with different floor plans, and optionally, a retail level with underground parking.
