This paper puts forward the concept of 'standard obstructions' for interior lighting calculations. Standard obstructions may be used as the basis of the calculation of light loss factors for use in the design of lighting for interiors whose ultimate use is not known. They may also be used as benchmark validation tools for interior lighting analysis computer programs that have a capacity to handle internal obstructions
