Angle-selective irradiation insulation on a building envelope

Abstract

In a method for producing a building envelope part (19) for angle-selective irradiation insulation on a building envelope, which building envelope part (19) has an outer surface (29), an inner surface (39) opposite the outer surface (29), and a side edge that bounds the outer surface (29) and the inner surface (39), the outer surface (29) is provided with outer structures (219) and the inner surface (39) is provided with inner structures (319). The outer structures (219) and the inner structures (319) are arranged relative to each other in such a way that the building envelope part (19) has different transparency depending on the spatial angle of incidence. The outer structures (219) and the inner structures (319) are arranged in particular with regard to an orientation of an intended application of the building envelope part (19) and with regard to the latitude of the intended application of the building envelope part (19). By means of the design of the outer structures and the inner structures according to the invention, it is possible that the outer structures and the inner structures are arranged in such a way that a building envelope comprising the building envelope part is optimally adapted to an orientation and in particular to an orientation deviating from southern orientation, to tilted or horizontal arrangements, or to an arbitrary latitude. Thus the transmittance behavior of the building envelope part can be accordingly optimized for the particular situation.

Description

BENEFIT CLAIM[0001]The present application claims the benefit under 35 U.S.C. 119 of priority from international application PCT / EP2012 / 061835 filed 20 Jun. 2012, which claims priority to European application EP11170686.7 filed 21 Jun. 2011, the entire contents of which are hereby incorporated by reference for all purposes as if fully set forth herein.TECHNICAL FIELD[0002]The invention relates to a building envelope part according to the preamble of independent claim 1, as well as to a method for manufacturing such a building envelope and a computer program for implementing such a method.[0003]Such building envelope parts exhibit an outer surface with outer structures, an inner surface opposite the outer surface with inner structures, and a side edge that bounds the outer surface and inner surface, wherein the outer structures and inner structures are arranged relative to each other in such a way that the building envelope part has a varying translucency depending on the spatial ang...

AI Technical Summary

Benefits of technology

[0032]The outer structures are preferably designed to diffuse light, wherein a light-diffusing effect for the outer structures is provided in such a way that a light band passing through the building envelope part is widened by a factor of roughly three from the exterior side up to the interior side. This type of configuration for the outer structures makes it comparatively easy to manufacture an efficient building envelope part with light diffusers as the outer structures as described above. However, the mentioned expansion factor can also be differently configured depending on the situation, wherein it can range from 2 to 5, for example.

[0033]The outer structures and inner structures are preferably given a lamellar design. For example, the term “lamellar” can be understood as a parallel arrangement of stripes in a plane, wherein these stripes exhibit straight sides and a specific width, for example. This type of lamellar configuration for the outer structures and inner structures enables a comparatively simple, efficient construction and manufacture of the building envelope part.

[0034]Another aspect of the invention relates to a computer program, which exhibits program code means configured to at least partially implement the method described above when the computer program is run on a computer. This type of computer program makes it possible to comparatively easily, quickly and precisely carry out the method according to the invention. In addition, this type of computer program makes it possible to implement and distribute the method according to the invention in an expedient and efficient manner.

Problems solved by technology

As a result, the known building envelopes of building envelope parts are either unsuitable or limitedly effective for orientations that deviate from the south, for inclined or horizontal configurations, for example roof surfaces, as well as for other geographic latitudes.

As a consequence, the irradiation on the building is often very high when the building exhibits such a known building envelope, and the amount of irradiated energy is often significant given the longer duration of sunshine in the mornings and evenings, and can help cause the building to overheat.
