Effect of surface reflectance on lighting efficiency in interiors
Rohini Singh, Rajan Rawal Abstract:
The paper attempts to analyze the relationship between surface colour reflectance and lighting power density for a given context. Analysis was based on digital modelling using validated lighting simulation tool. The study establishes itself on the premise that grey value of colour can be presumed
to calibrate the luminous character of light. Also, it evaluates the impact of vertical and horizontal planar interior elements’ reflectance and its impact on LPD. This is done through different scenarios derived from the basecase. All derived scenarios were then confirmed to the established visual comfort standard. The results were collated to develop a colour chart.
