Architectural facade lighting refers to the lighting design and installation of exterior building facades to highlight architectural features, improve aesthetics, enhance visibility, and add to the overall ambiance of the building. There are several types of architectural facade lighting, including:
1. Wall Grazing: This lighting technique is used to highlight the texture and depth of a building's facade by casting light along the surface of the wall.
2. Wall Washing: This technique involves casting a broad and even wash of light over the entire surface of the building's facade, providing a uniform illumination.
3. Accent Lighting: This is used to highlight specific architectural features or elements of a building, such as columns, arches, or sculptures.
4. Uplighting: This is used to cast light from the ground up to illuminate specific areas of the building's facade, creating a dramatic effect.
5. Silhouetting: This technique involves placing the light source behind the architectural feature, creating a dramatic silhouette effect.
6. Shadowing: This technique is used to create depth and texture by casting shadows on the building's facade.
