The Facade element

The invention relates to a facade element, in particular for the construction of 0 curtain and rear-ventilated facades according to the preamble of claim 1.

Facades for building walls are available in a wide variety of designs and are used on the one hand to visually design buildings and on the other hand to protect them from environmental influences, heat or sound insulation. In an age of rising energy prices, the environmental aspect of energy saving in buildings is becoming more and more important.

It is therefore an object of the invention to propose a facade element which contributes both passively and actively to energy saving or energy source saving.

This problem is solved by the features of claim 1.

An essential feature of the invention is that the facade element essentially consists of a plurality of solar panels running approximately parallel to one another for generating heat and/or electricity, wherein the solar panels are arranged at a fixed or variable angle to the building wall.

This has the advantage that the facade element not only serves to improve the insulation effect of the building, but also actively uses solar energy to generate heat and/or electricity.

In contrast to solar panels arranged on the roof of a building, such facade elements can be handled more easily in terms of design.

Since the facade element is preferably arranged at a distance from the building wall, the result is a curtain-type, rear-ventilated facade.

In one embodiment of the invention, the solar panels run approximately horizontally. In this embodiment, the facade element 0 is preferably used for installation on the south side of a building, with the panels having an angle of inclination relative to the horizontal of preferably 60°. However, any other angle of inclination can also be provided.

In a second embodiment of the invention, the long sides of the solar panels run approximately perpendicular, i.e. vertically, so that this type of facade element is preferably suitable for installation on the west and east sides of buildings, since the individual solar panels can be aligned in any direction between southwest and southeast due to a vertical angle of incidence.

In order to achieve the highest level of energy yield, a preferred embodiment of the invention provides that the angle of the solar panels

can be automatically adjusted to the angle of the sun's rays using a motor. Any type of suitable motor, e.g. an electric motor, can be used.

As already mentioned above, the solar panels can be designed as photovoltaic modules and/or solar collectors for generating hot water. Any combination is also possible.

Preferably, the solar panels are arranged on a mounting wall, firstly to obtain a stable facade element that is easy to install and secondly to have the option of laying the supply lines for the solar panels in or on the mounting wall. These then only need to be connected to the appropriate central connections.

In an alternative design, such a facade element can also be used as a type of blind, in which the mounting wall is completely or at least partially transparent or opaque. This means that the facade element can also be arranged in front of window surfaces, whereby sufficient light still penetrates through the mounting wall.

The embodiments of the invention are explained in more detail below with reference to drawing figures. Further features and advantages as well as areas of application of the invention can be seen from the drawings.

Figure 1 shows a building wall 4 with a suspended, ventilated facade element according to the invention, which comprises a mounting plate 3 and several solar panels 1 mounted on it. Figure 1 shows a vertical section, i.e. the solar panels run with their long side in a horizontal direction and are set at an angle 2 to the vertical so that the solar radiation 5 can be optimally utilized. When using both photovoltaic modules and solar collectors, supply lines 6 are necessary, which can be routed, for example, between the mounting wall 3 and the solar panels 1.

Figure 2 shows an embodiment modified from Figure 1, with solar panels 1 arranged on the mounting wall 3 so that they can be moved and pivoted, the angle of incidence 2 of which can be changed over a predetermined range. For this purpose, the solar panels are connected to an adjusting element 7 which is driven by a motor in the direction of arrow 9 so that the angle of incidence 2 of the solar panels 1 changes. Since this is a ventilated facade, air circulation in the direction of arrow 10 between the building wall 4 and the facade element is possible.

Figure 3 shows a schematic cross-section through a timber frame building, consisting of corner pillars 11 to which the building walls are attached, which consist of an inner wall 12, an outer wall 14 and an insulation 13 in between.

The facade element is also attached to the corner pillars 11, for example by letting the mounting wall into a groove in the corner pillar and attaching the solar panels 1 to the mounting wall. Vertically mounted solar panels 1 are shown at the top left, the angle of which can be changed using an adjusting element 7 and a motor 8. This can be the west side of a building, for example, where the solar panels 1 can be guided along the path of the sun from south to west.

Figure 3 below shows horizontally mounted solar panels 1, which are preferably arranged on the south side of a building and whose angle of incidence can also be changed via an adjusting element 7.

Figure 4 again explains in perspective the possibilities of designing the facade elements according to the invention, with both horizontally extending solar panels 0 and vertically arranged solar panels forming the outside of the facade element, with the solar panels 1 preferably being attached to a mounting wall 3. However, this mounting wall 3 can also be omitted and instead the solar panels can be connected to one another via struts or supports.

The solar panels can, as described above, be adjusted to the angle of the sun's incidence, whereby the angle of the solar panels 1 is greatest at midday and can be reduced to zero at night, for example, so that the solar panels lie flat on the mounting wall 3 and provide additional visual and thermal protection. Such facade elements can not only be used on building walls, but also free-standing as a privacy screen for pergolas,

as free-standing "energy walls", as noise barriers in connection with energy generation or many other areas of application.

It is advantageous that the facade elements according to the invention can be used on the east, south and west fronts of buildings with the highest possible energy yield, depending on the orientation of the solar panels, and can be prefabricated to a high degree, with the connecting cables already integrated into the individual modules and being able to be connected directly to other modules or central connections.

Figures 5 and 6 show the use of the facade element as a folding element for shading a winter garden 15.

Figure 5 shows the solar panels in the open position, with them aligned at an optimal angle 2 to the direction of sunlight 5. The solar panels 1 are arranged on the glass roof of the winter garden 15, which serves as a mounting wall 3. The inclination of the solar panels 1 allows glass elements 16 to be installed, which ensure good light incidence in the winter garden 15, without direct sunlight.

Figure 6 shows the solar panels 1 in the closed state, where they lie flat on the conservatory roof (mounting wall 3). This completely shades the conservatory 15 while generating energy at the same time.
