Quantifying the effects of interior surface reflectance on indoor lighting

The current study analyzed the relationship between reflectance of interior surfaces and distribution of artificial light through visual comfort indices by DIALux evo software. The relationships were assessed through a statistical analysis by SPSS. The quantitative comparison between surface reflectance and these indices showed that wall visible reflection coefficient had the most important role for determining the variations of visual comfort parameters. The findings of this work could be applied in interior spaces mainly designed based on artificial lighting, such as museums, galleries and indoor exhibitions also by paying attention to energy saving perspective.
