Building facade lighting refers to the use of lighting fixtures and techniques to illuminate the exterior surfaces of buildings, enhancing their architectural features and creating visual interest. This type of lighting is often used to highlight the unique design elements, textures, and materials of a building's facade, as well as to provide visibility and safety at night. Facade lighting can range from simple, subtle lighting accents to more elaborate, dynamic lighting schemes that change color or intensity. It plays a crucial role in enhancing the aesthetics of buildings, creating ambiance, and contributing to the overall visual appeal of urban landscapes.
