a renovation of a small parisian studio apartment focuses on a the relationship of different light qualities within the space, employing
binary sources of artificial illumination. french firm betillon / dorval-bory used an incisive, scientific approach to light within the
built form, using a range of indices to evaluate specific moments of color and spectral distribution. of particular use was the color
rendering index (CRI), a fundamental criteria for evaluating light that assesses the homogeneity of color rendering with respect to
spectral power distribution (SPD.) a low CRI range, for example, results in a loss of color range. given the technical considerations of
the project, lighting with alternately low or high CRI is composed according to the program– the kitchen and living room required
color distinguishing illumination, while the bed and shower merely require monochromatic light. the bipolarity of the light quality
helps shape the space, instead dictating use, circulation and paths of movement free of a plan and following the logic of composition
generated by light.
light with a low CRI number is used in the bedroom area

the architects strove to make interiors as neutral as possible, so as to allow the binary system to create a logical composition

the warm light is emitted from some low pressure sodium lamps with zero CRI
