👉 The word 'Subtractive Lighting' refers to a type of lighting that minimizes direct, or direct-sunlight exposure in an interior space. This method aims to reduce glare from sunlight by minimizing direct solar light sources like windows, mirrors, and walls. Definition: Subtractive Lighting involves using reflective materials to reflect indirect sun rays away from the home, reducing the need for windows and other direct sources of light. Materials used include plastic panels or a reflective sheet placed over windows or walls. This is achieved through careful selection and placement to maximize light retention while minimizing heat loss due to direct sunlight exposure.
