<p>The invention provides light and heat controlling panels which may be used for example as facings for walls or as roof elements. The panels can also be used as energy concentrators for concentrating light energy onto energy collectors associated with the panels or with the walls, etc. on which they are located. Thus, the panels can be used as an equipment for the automatic control of the incidence of solar radiation. Each panel consists of two spaced light-transmitting wall elements between which are disposed a plurality of lightimpervious elements horizontally-oriented and parallel to each other, the upper and lower-sides of two immediately adjacent elements being of different profile and forming an incidence and a concentration space for the radiation. An energy collector may be disposed in this concentration space. Depending on the angle of incidence of the solar radiation a certain amount is reflected back through the incoming side into the outer space, the amount of reflected and transmitted energy varying with the change of seasons. Energy transmission through the panel will be increased in the cooler seasons characterised by lower angles of incidence, while the energy reflection is increased in the hotter seasons characterised by higher angles of incidence. The relative energy transmission and reflection is controlled by means of choice of the shape and disposition of the element profiles. Heat control of a building is achieved by using the panels as a curtain wall therefor.</p> |
