[0003] The world calls for more sustainable solutions in general but especially within the construction industry, and therefore new solutions within construction elements, such as building facades, are requested.

[0004] Particularly, the facade of a building or any other construction weighs heavily in the environmental climate footprint of a construction. Therefore, to provide a replacement of the conventional facade element used today, such as a traditional sandwich element, would provide an enormous advantage.

[0005] The difference in the environmental climate footprint would be clear to see in the sustainability report of a building, if a facade element is green, sustainable and environmental.

[0006] Within the climate footprint of a building, it is often particularly the CO 2 emission and consumption which are in focus, and therefore a new facade element wherein the CO2 emission and / or consumption decreases significantly compared to a traditional sandwich facade is hugely needed and requested in the construction industry.

[0007] Today, numerous solutions of facade elements are available, however, none of them have focus on the environmental climate footprint but focus more or less only on the design of the facade and the strength and / or load capacity of the facade construction.

[0008] Hence, an improved element, preferably an efficient and reliable facade element, suitable for being used in any construction, such as a building, would be advantageous, and in particular more resistant, mechanically strong, economical, sustainable elements with longevity would be advantageous.OBJECT OF THE INVENTION

[0009] It is an object of the present invention to provide an alternative to the prior art.

[0010] In particular, it may be seen as an object of the present invention to provide a building facade element that solves the above-mentioned problems and provide the above mentioned advantages.DESCRIPTION OF THE INVENTION

[0011] Thus, the above-described object and several other objects are intended to be obtained in a first aspect of the invention by providing a wall construction, preferably a facade wall construction, said wall construction comprising: a front wall structure made at least partly of concrete, a ventilated cavity, isolation material, a back wall structure made at least partly of wood material, preferably said back wall structure is: one or more cross laminated timber (CLT) plates, or one or more laminated veneer lumber (LVL) plates, at least one bracket, wherein the front wall structure and the back wall structure are connected via the at least one bracket.

[0012] The invention is particularly, but not exclusively, advantageous for providing a hybrid element. The element may be seen as an advanced development of the conventional sandwich element. One difference and advantage between the new element and the traditional known elements is that most of the concrete and steel is replaced with wood, if not all is replaced. The replacement is of great importance for the environmental climate footprint, however, this improvement does not affect the ability to still obtain the desired appearance or durability of a construction / building. The durability may even be enhanced.

[0013] The facade weighs heavily in the environmental climate footprint of a building. Therefore, it makes an important difference in the footprint to replace the conventional elements with the new sustainable element. It is especially seen that the CO 2 consumption and emission decreases significantly compared to a traditional facade element, such as known sandwich elements.

[0014] A large part of the difference in the environmental pollution and contamination comes from the use of wood as a back wall structure, such as a back plate.

[0015] In the case of conventional sandwich facades, the back plate typically consists of solid reinforced concrete. Within the invention, the back wall structure consists of 100% wood, preferably cross-laminated solid wood (CLT) and / or laminated veneer lumber (LVL). This means that the invention simultaneously reduces the consumption of cement and steel and adds wood instead, which contributes positively to the environmental footprint.

[0016] The wall construction can easily be matched to individual projects since the inner surface of wood can be obtained in different qualities, and it is also possible to produce rabbets and notches in wood, if desired. Also, the front wall structure and insulation can be varied to suit any individual project.

[0017] This makes the invention of the new facade wall structure an optimal solution regardless of whether the project dictates brick facades or something else - and regardless of what insulation is needed.

[0018] Furthermore, it is possible to use CO 2 -reduced concrete for the front portion and reduce the environmental impact and damages even further.

[0019] Moreover, further advantages can be highlighted such as the strength and durability of the wood, the strength and durability of the concrete, the high aesthetics and weather resistance of the bricks, if bricks are used, and the flexibility of the element system, fast construction time and industrial prefabrication.

[0020] The wall structure can be produced and delivered with installed windows and possibly internal plasterboard cladding and any desired type of coverage.
