In this paper the authors present the first experimental results about the natural ventilation obtained by a device called Ventilated Illuminating Wall (VIW); which carries out the function to introduce natural light in underground areas or that don’t have facing outwards; contemporarily operating in the same areas a natural ventilation effective action necessary to guarantee thermal comfort and healthy conditions to the occupants.

The VIW is represented by a 1:1 prototype scale model; constituted by a precast removable manufactured product set to a window of a room. Such device is able both to transport the natural light; captured by the coverage; in underground areas and to introduce outside air for the required ventilation through the vents positioned both inside the room and in the retaining structure of the coverage.

Our study’s objective is to verify experimentally; through air speed measurements in different points; if in every condition the indoor air quality is guaranteed.

The results about daylight performances of the system are satisfactory; besides they show that the VIW is able to assure a significant natural air ventilation; but the thermal analysis can be improved measuring the air mass flow rate and the comfort parameters for the occupants.
