Objective The project aims to demonstrate that a Regulated Energy Absorption (REA) solar roof :- can cover the energy needs of an Appartments Block for space heating in the winter (80% for the East House Unit, without heat storage, and 90% for the West House Unit, with heat storage) and all needs in domestic hot water all over the year;- can be aesthetically integrated in the house architecture;- furthermore to demonstrate the possibility of heat-storage in a xater tank directly burried in the ground without special insulation.The "REA" solar houses consist of 4 appartments, two in the East House Unit and two in the West House Unit.The West House Unit is composed as follows :- at the basement, an appartment of 60 m2;- at the first and second floor, the main appartment of 190 m2;- an underground water tank of about 60 m3 and a domestic hot water tank of 400 liters.The East House Unit is composed as follows :- at the basement, an appartment of 70 m2;- at the first and second floor, the main appartment of 190 m2;- a 400 liters domestic hot winter tank.The Solar Roof "REA" in each house is divided in two collectors : the south collector with an area of 40 m2 each and Side-Collector with an area of 30 m2 approx., with an adequate slope of each roof-part.The "REA" are transparent polycarbonate plates (1 cm thick, 32 cm wide and 12 m long) consisting of two sets of parallel rectangular tubes one in front the other. The external set plays the role of the glazing of a conventional collector. In the internal set circulates a special colored liquid for the absorption, varying from black (for highest absorption) to all transparent (for minimal absorption). Only the all-black version is realized. Both ends are formed into tube collectors. The plates are placed one aside the other.Each two aside plates are connected with special metallic profiles of U-shape which create also the supports of the solar roof.The collectors of the upper end of each polycarbonate plate are all connected to the way-out circulating tube and those of the lower ends to the way-in circulating tube of the absorbing liquid.The system is completed with a stand-by boiler to cover the remaining energy needs.The solar collectors deliver the heat to the DHW storage tank or to the hyge storage tank (60 m3). The heat is delivered to the house through floor heating, which is at low temperature and compatible with the low temperature heat from the solar collectors.
