Architectural engineers have a much stronger knowledge of building systems and structural characteristics than architects, but they have a more holistic approach to structural design than engineers. Typically, an engineer will choose a column or beam that perfectly meets the requirements of structural loads, whereas the architectural engineer will choose elements that are in harmony with one another and the overall structure.
The architectural engineer works with mechanical, electrical and plumbing engineers to choose systems that integrate seamlessly with a structure. Though a traditional architect has a strong understanding of these systems, the architectural engineer has more training with these technical aspects of building design.
Most universities offering architectural engineering degrees require students to choose a specialty in the building sciences. Although architectural engineering requires knowledge of all topics, the specialty allows the architectural engineering student to become an expert in a building aspect of his or her choosing. Therefore, certain architectural engineers may offer expertise beyond any engineer or architect for special building types. For example, an architectural engineer with a specialty in acoustics will be a better theater or auditorium designer than a traditional architect or engineer.
Architectural engineers are trained in building design, like an architect; however, they approach the design more practically -- relying on the nature and form of the structural, mechanical, electrical and plumbing systems to define the architectural form. In contrast, the architect will use the building systems, as well as societal and artistic needs, to define a building's design.
