Definitions

  • the invention relates to a double facade with the features the preamble of claim 1.
  • Double facades consist of an inner facade and a Outer facade. Between the inner facade and the outer facade there is a space that is usually ventilated is.
  • Double facades There are various basic concepts in technology Double facades known. Essential problems here are to provide good insulation at the same time but with a good passive use of solar energy one Risk of overheating in summer with strong solar radiation prevent.
  • a thermally insulated interior facade provided that can have openable windows. At a distance in front of this, an outside facade is made with uninsulated single glass curtains, which also have openable elements can be.
  • the advantages of a double facade are: natural ventilation even in high-rise buildings weather-protected sun protection and an effective Vorschallschutz.
  • DE 44 24 524 C2 describes a double facade with a integrated in the area between the inner and outer facade Sun protection device, the outer facade being double-skinned is trained and the sun protection devices between the shells of the outer facade are arranged.
  • the advantage this solution is that a possible one Condensation does not form in the space between the facades, but at most between the glass panes of the outer facade can occur, but where appropriate by appropriate measures can be reduced or even eliminated.
  • By the in Summer solar energy is prevented until penetrate into the space between the facades can be opened very effective way to avoid greenhouse effects.
  • the Sun protection is compared to that described above Standard concept significantly improved.
  • the glass panes of the External facade can be designed as an insulating glass with between closed air volume.
  • the invention has for its object a double facade propose an improved with little effort Sun protection and improved weather behavior allows.
  • the invention is based on the idea, not as in the prior art a sun protection in the form of a blind is common in technology to provide, but special glazing for the External facade to be used by an electrochrome and / or phototropic and / or thermotropic glazing for use arrives.
  • Electrochromic glazing changes the light absorption as well as energy permeability depending on one applied electric field strength while phototropic glasses a reversible color change under the influence of light Experienced.
  • Phototropic glasses are so-called photosensitive Glasses known in the optics of glasses. Are thermotropic glasses coated with a thermo-optical polymer and change the light transmission depending on the temperature. With thermotropic glasses there is no direct one Relationship between the light intensity of the sun and the Translucency of the glazing, but here is the warming radiation energy of the sun in the same way darkening of the glazing.
  • the at electrochromic, phototropic or thermotropic glazing Any changes that occur are reversible and can with electrochromic glazing depending on the applied electrical field strength reversed again with phototropic or thermotropic glazing creates a self-regulating effect due to the direct dependence on solar radiation.
  • the outer facade of single laminated glass is to realize particularly inexpensively.
  • the outer facade includes insulating glass.
  • This Variant has the advantage of improved thermal insulation the facade. Sun protection is also further improved.
  • the exterior facade with insulating glass is located Electrochromic or phototropic or thermotropic layer in the inner glass of the insulating glass. This becomes the inside of the facade under the glass inside insulated glass arranged understood. Alternatively, however also electrochromic or phototropic or thermotropic Layer in the outer insulating glass, whereby the sun protection is further improved.
  • the Inner facade and possibly also the outer facade openable elements e.g. openable windows.
  • the ventilation properties of the ventilated space between the inner facade and the outer facade the double facade according to a preferred embodiment, inlet and outlet openings in the outer facade to a Flow connection between the space and the To create an outside climate.
  • inlet and outlet openings preferably arranged so that there is a floor-by-floor ventilation of the space is possible.
  • Fig. 1 shows in vertical section a double facade, the Structure not essential for understanding the invention is. So in the following the structure of the openable is not Insulated interior facade 12 with window 14 are explained.
  • the main point is that the outer facade has 16 glasses, the electrochromic or alternatively are phototropic or thermotropic.
  • the 1 shows the outer facade Single laminated glass 18 on which is an electrochromic layer has. Electrochromic glasses are made by one electrochromic film is embedded in a laminated glass.
  • the inner facade can be in the form of a metal facade, one Brick wall with perforated windows, fixed glazing or in be formed in a similar manner.
  • For natural ventilation Windows that are mandatory to be provided may open necessary maintenance work in the area of Facade space 22 easily possible.
  • the desired Sunscreen effect either occur manually by the Users with appropriate sun intensity over a Control device the degree of darkening of the outer glasses or automatically, for example by Radiation energy meters or temperature sensors a control device the permeability of the outer glasses regulate.
  • electrochromic outer glasses stands a little polluting, easy to clean and weatherproof sun protection ready to go directly into the Exterior glasses is integrated and already penetrating one undesirably high radiation intensity in the Facade gap 22 prevents.
  • thermotropic glasses As an alternative to the provision of electrochromic outer glasses, the embodiment of FIG. 1, but also all Execution alternatives described below also phototropic or thermotropic glasses can be provided. Different than with electrochromic glasses, in which by electrical Fields introduced a change in energy permeability , phototropic glasses darken under the influence of UV radiation from sunlight and thermotropic glasses in Dependence on the temperature, but not the Light intensity. There are different types of thermotropic glasses Phases before that have a different temperature dependence of the refractive index, so that the refraction of light and thus light transmission depending on the temperature is changeable.
  • FIG. 1 there are also intermediate spaces 24 between individual outer glasses 18, which serve for the inflow and outflow of air.
  • arrow A is shown in the illustration in FIG. 1, which indicates the inflow of supply air into the facade interspace 22.
  • the individual facade interspaces 22 each extend over a storey height, so that the facade interspace is ventilated by storey.
  • the spaces 24 shown in FIG. 1 can simultaneously serve the inflow but also the outflow of air, which is indicated by the additional arrows A - B - .
  • a control option for the air flow in the rear-ventilated double facade is not the subject of this invention and is therefore not explained in detail.
  • fans can be used which support the forced convection of the air and are operated, for example, via solar cells arranged in the space between the facades, and consequently are also regulated in terms of their output in relation to solar radiation.
  • the provision of natural ventilation in all weather conditions provides the prerequisites for a simple night cooling system for the building. This measure also leads to an improvement in thermal insulation and noise protection.
  • FIG. 2 shows an alternative embodiment of the invention, which differ from the embodiment of FIG. 1 only in the Formation of the outer facade 16 differs.
  • the outer facade As Insulating glazing is provided, which consists of an outer glass 28 and inner glass 30 is constructed.
  • electrochromic film 20 is located the electrochromic layer in the inner glass 30 of the Insulating glass.
  • a phototropic or thermotropic Layer should be provided.
  • the provision of double glazing in the outer facade has the advantage that the Double facade an improved thermal insulation as well as a has improved sun protection.
  • Like that 1 is provided by the provision of electrochromic glass in the facade space 22 and from there through the window 14 into the room Radiation intensity reduced.
  • FIG. 2 can also in one alternative, the embodiment shown in FIG Exterior facade 16 can be designed with insulating glass, wherein however, the outer glasses 28 are electrochromic and thus in Depending on the radiation intensity can be darkened.
  • the advantage of the embodiment according to FIG. 3 compared to 2 is that the unwanted radiation is already intercepted and reduced in the outer glass 28 and not only through the i.A. air or gas-filled room 32 between the insulating glasses 28 and 30 to the inner glass 30 forced out.
  • FIGS. 1 to 3 the entire area formed by glass elements Exterior facade with electrochromic or alternatively phototropic or thermotropic glasses.
  • Fig. 4 shows an alternative embodiment in which in Dependency on a predefined beam of the sun only some of the outer glasses 18a with electrochromic glasses be provided, while other areas of the outer facade 16 provided with outer glasses 18 without an electrochromic layer are.
  • This measure can be used to: the sun rays falling on an inner window 14 from Barring interior window 14 while otherwise preventing intrusion the solar radiation in the facade space 22 allowed becomes.
  • This measure can reduce the cost be by the less expensive outer glasses 18 without electrochromic, phototropic or thermotropic properties there be used where that through this incident sunlight does not fall on an interior window 14.
  • it can Arrange electrochromic, phototropic or thermotropic Exterior glasses but also made according to other criteria and for example depending on the direction of the double facade and the climatic conditions at the location of the building specified percentage of the outer glasses electrochromic, be formed phototropically or thermotropically.
  • the double facade according to the invention has the advantage of a variably adjustable and effective sun protection system to be provided in the layered glass of the outer facade and is therefore neither exposed to the weather nor can pollute.
  • integrating the sun protection in the outer glass of the double facade can also be the Improve sun protection and an improved one Achieve ventilation behavior because none separately to be provided in the area of the through-flow facade space are to be provided and thus the complete cross section of the facade space is available for air circulation.
