**4.2 Numerical analysis on the square modular form equipped with four VDLP**

An intense numerical analysis was carried out by the authors in steady state condition with the aim of determining the daylight illuminance and luminance distribution by the sw Radiance and Ecotect, while the sw package Fluent /Airpak was used in order to calculate the air velocities and temperatures in the room, besides the thermal comfort index PMV and PPD.
