Architectural engineering is an interdisciplinary field that integrates the principles of architecture and engineering for the design, construction, and operation of buildings and their technical systems. This discipline investigates the performance, safety, and sustainability of the built environment, focusing on aspects such as structural integrity, mechanical systems (HVAC), electrical systems, lighting, acoustics, and fire protection. Its significance lies in ensuring buildings are functional, efficient, safe, and resilient while aligning with architectural design intent and regulatory requirements.
