This thesis proposes an alternative metric and standard for
lighting design based on luminance—the amount of light reflected off a
surface—along with instructions for their use. The luminance metric is an
alternative to the current standard of illuminance—the amount of light hitting
a surface. The illuminance metric is problematic because humans often make
judgments based on light’s reflection and contrast, variables better captured
by luminance. Using the design of a conference room as a case study, this
project establishes the advantages and feasibility of the luminance metric.
