In lighting design, the lumen method, (also called zonal cavity method), is a simplified method to calculate the light level in a room. The method is a series of calculations that uses horizontal illuminance criteria to establish a uniform luminaire layout in a space. In its simplest form, the lumen method is merely the total number of lumens ...

Architectural lighting design is a field of work or study that is concerned with the design of lighting systems within the built environment, both interior and exterior. It can include manipulation and design of both daylight and electric light or both, to serve human needs. [1] [2] Lighting design is based in both science and the visual arts.
Space By Space Method A defined list of many possible space types within a building the associated watts per square foot allowance. For example, ANSI/ASHRAE/IESNA Standard 90.1-2007 allows the Emergency Space of a hospital to be designed for 2.7 watts per square foot, but the Recovery areas of a hospital would be allowed 0.8 watts per square foot.
A third approach uses indoor light measurements showing that between 108 and 5,400 lux have been achieved in the space. The last approach is a combination of the other three calculation methods to prove that the daylight illumination requirements are achieved. [46] The LEED 2009 documentation is based upon the daylight factor calculation. The ...
