Window design refers to the process of creating and planning the appearance and functionality of windows in buildings. It involves considerations such as size, shape, materials, and placement to enhance both aesthetics and energy efficiency. Proper window design can improve natural light, ventilation, and overall comfort in a space. Incorporating elements like double glazing or energy-efficient frames can help reduce energy costs and improve insulation. Additionally, window design can influence the architectural style of a building, whether it be modern, traditional, or industrial. Thoughtful design choices contribute to the overall harmony and functionality of a structure.
