What is the difference between Architecture and Architectural Engineering?

Architecture is the art of organizing physical spaces to accommodate human actions. Architecture includes the breadth of design of the built environment that balances the aesthetic and functional requirements of usable spaces and environments. Architectural Engineering is the science of designing the components of a building, facility, or structure to facilitate the functions of a building. The engineering systems required of built structures include electric power; communications and control; lighting; heating, ventilation and air conditioning; and structural systems.
