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 colorrendering index (CRI), a fundamental criteria for evaluating light
|
that assesses the homogeneity of color rendering with respect tospec tral power
|
distribution (SPD.) a low CRI range, for example, results in a loss of color
|
range. given the technical considerations ofthe project, lighting with
|
alternately low or high CRI is composed according to the program-- the kitchen
|
and living room requiredcolor 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. |
