Journal of Engineering Research
Architectural projects often rely on modern technologies like smart architecture and environmental treatments, neglecting the principles and philosophy that reflect civilization, ideas, culture, and traditions. This leads to short-lived buildings that depend on these technologies without any purpose of preserving them. Technicians must constantly renew technology to improve production and without benefits, as threats of superior artificial intelligence have been warned, that autonomous machines may perform tasks without programmers understanding how to reach this level. Instead of relying solely on environmental or smart technology, we should make technology serve the design idea rather than relying solely on it. Considering this, …
