Architectural engineering deals with the scientific study of the principles of engineering, and their application to design and construction. Research in this field focuses on the aesthetics of design, viable geometry and relevance to the diverse aspects of modern society. Experts are constantly striving to extend the limits of architecture through investigations in building design, materials and energy efficiency. Modern architecture explores the technological aspects of software architecture and computer graphics for elaborate design and planning. Contemporary constructions work within the principles of urban planning and take into consideration resilience to natural hazards and fatigue limits of buildings
