Architectural engineering is a relatively new licensed profession, emerging in the 20th century as a result of the rapid technology advancement of the Industrial Revolution. Architectural engineers are the engineers that specialize in making buildings. This is a particularly important profession today, since our world is immersed in two major technological revolutions,  that of rapidly advancing computer-technology, and  the parallel revolution arising from the need to create a sustainable planet. Architectural engineers are at the forefront of both historical opportunities.
