A window is an architectural element and design feature consisting of an opening in a wall, roof, or vehicle that allows the passage of light, air, and views between interior and exterior spaces. This fundamental component of architectural design has evolved significantly throughout history, from simple openings in ancient structures to sophisticated systems incorporating advanced materials and technologies. The design of windows encompasses multiple considerations including thermal efficiency, acoustic performance, aesthetic appeal, and functional requirements, making them crucial elements in both architectural and industrial design. Windows serve multiple purposes in design: they establish visual connections between spaces, regulate environmental conditions, contribute to energy efficiency through natural lighting and ventilation, and significantly impact the overall aesthetic character of a structure. Contemporary window design has been revolutionized by innovations in glazing technology, frame materials, and smart systems that can automatically respond to environmental conditions. The integration of sustainable design principles has led to the development of energy-efficient windows that incorporate features such as low-emissivity coatings, multiple glazing layers, and thermal breaks. These advancements have been recognized in various design competitions, including the A' Design Award's Construction Materials and Components Design Category, where innovative window solutions are evaluated for their contribution to architectural excellence. The cultural and psychological impact of windows in design cannot be understated, as they influence spatial perception, well-being, and the human connection to the natural environment, making them essential elements in both residential and commercial architecture.

Roundel is a term used in graphic design to describe a circular emblem or logo, often featuring concentric rings, text, or symbolic imagery. Originating from heraldic designs on medieval shields, roundels have evolved to become a versatile and widely recognized design element. They are commonly employed in branding, signage, and insignia for various organizations, such as airlines, automotive companies, and military units. The circular shape of the roundel provides a compact, visually striking, and easily recognizable format for conveying identity or affiliation. Designers often use contrasting colors, bold typography, and simplified iconography within the roundel to ensure legibility and impact across various media and scales. The use of roundels extends beyond corporate branding, finding application in wayfinding systems, packaging design, and even modern art and fashion. The enduring popularity of the roundel can be attributed to its ability to communicate a sense of unity, coherence, and visual harmony while allowing for creative interpretation and adaptation to suit diverse design contexts.
