The conventional B-C system is integrated on the external side of the south wall and on the roof of the building. It consists of a glass, an
Steady
Passive solar systems are one of most important strategies to reduce the heating loads of buildings. The Trombe–Michel (TM) wall and its variants are some of the better-known structures in the field of solar systems. An alternative to the TM wall is the Barra–Costantini (BC) system. In the present paper, CFD numerical simulations, both in

USING THE BARRA-COSTANTINI SYSTEM FOR MULTISTOREY
The Barra-Costantini(BC) system is a passive tool which can be successfully applied to such dwellings, due to the ceiling floor used as thermal storage and the absorber disconnected from the south facing wall. This allows an uniform distribution of the air among several rooms, as the heat is conveyed trough ceiling channels.
(PDF) Passive solar systems for buildings: performance indicators
In the Barra-Costantini system the warm air is released at the non-sun facing rooms, heating the distant part of the building, and flowing back guaranteeing the best heat distribution. A main disadvantage is the hard maintenance: air movement can collect dust between the glazing surface and the wall or condensation may occur during cold nights.
Barra system
The Barra system is a passive solar building technology developed by Horazio Barra in Italy. It uses a collector wall to capture solar radiation in the form of heat. It also uses the thermosiphon effect to distribute the warmed air through channels incorporated into the reinforced concrete floors, warming the floors and hence the building.

Barra system
The Barra system is a passive solar building technology developed by Horazio Barra in Italy. It uses a collector wall to capture solar radiation in the form of heat. It also uses the thermosiphon effect to distribute the warmed air through channels incorporated into the reinforced concrete floors, warming the floors and hence the building. Alternatively, in hot weather, cool nighttime air can be drawn through the floors to chill them in a form of air conditioning.

What is Barra-Costantini system?
Abstract. It describes the passive solar system, developed in Italy and called Barra-Costantini System, from the name of Barra who concei-ved the fluid dynamics and from Costantini who conceived the me-chanical part and applied it as an experimental prototype to his house in Salisano (Rieti).
What is the difference between Barra-Costantini and glazed PV glass panels?
The conventional Barra-Costantini system gives an internal air temperature of 22.9 °C, while systems with glazed semi-transparent PV and semi-transparent PV only produce temperatures of 22.6 °C and 21.5 °C, respectively. The maximum electrical efficiency of the PV glass panel is 15.6%, while that of the glazed PV glass panel is 13.1%.
