In this paper the authors present the results of a numerical analysis concerning the study of daylight transmission and thermal comfort in underground areas and basements of a building without any direct openings toward the external environment. The study was carried out on a two-level building; illuminated by the "Double Light Pipe" (DLP); an innovative technological device developed in the Laboratory of Technical Physics; Faculty of Architecture; Pescara; Italy.
The DLP consists of two concentric pipes of different diameter; able to illuminate both the final room and the intermediate one and to allow the entry and the extraction of the air inside the environments of life.
In this first phase; the authors carried out a numerical analysis by the soft-wares RADIANCE and ECOTECT with the aim to define the illuminance distribution in the intermediate room illuminated by the DLP in standard conditions of sky; in addition the CFD code FLUENT/AIRPACK is employed with the aim to define the thermal comfort level considering external wind condition; air temperature and solar radiation. The indoor air temperature and velocity; mean age of air and the indexes PMV and PPD have been evaluated so verifying the indoor air quality.
