synergetic

ZOE PRESENTATION_05_e-compressed-1

Art of joining
The design principle of zoë is unique and yet very simple! The complex physical and structural requirements of the building element are achieved through a highly efficient and synergetic assembly of layers from natural, non treated materials:

The standard structure of a module: wooden frame – straw filling – wood fiber board (outside) – wooden frame with straw filling (view from the inside) – clay coarse plaster – coloured clay fine plaster (optional)

  • The structural frame is built from light weight thermal bridge free I-joists  (TJI). > STEICOJoist
  • The frame is filled with certified, non treated straw (small bales or chopped straw) which forms the thermal and acoustic insulation.
  • The timber-straw element is sealed with clay from the inside. The clay ensures permanent capillary desiccation of the insulation material and prevention of fire, vermins and rotting.
  • A vapor-permeable wood soft fiberboard > AGEPAN THD static is at the same time plaster base, stiffening, additional thermal insulation and wind seal.

Use
With zoë modules, load-bearing or non-load-bearing exterior walls as well as roofs can be created for buildings up to eight storeys high. In a simple way, additional openings can be added later, existing buildings can be expanded or temporary structures can be created.

Geometry
The width and the length of the modules can be freely selected. The element thickness is derived from the beam widths and the thicknesses of the wood soft fiber boards used and can be selected depending on the desired thermal insulation standard.

The diagram shows a type 2 structure (see below): The zoë modules are stretched between the wooden ceilings and, together with the stiffening wooden walls, take over the ceiling loads inside.

Structure
The wooden frames made of double T-beams > STEICOJoist are just as viable as the corresponding solid wood sections with significantly lower weight and material costs. The wood fiber board on the outside of the wooden frame> AGEPAN THD static also contributes to the stiffening. In the joints between two modules additional posts (supports) can be used instead of the connecting wood slats depending on the static requirement (usually from three floors). With zoë module different structural concepts can be implemented:

Type 1a: The structure is formed of a concrete skeleton of columns and ceilings with a stiffening core. The zoë modules are stretched between two ceilings as filling elements. The concrete structure takes over all loads.

Type 1b: The structure is formed of a concrete skeleton of columns and ceilings with a stiffening core. The zoë modules are placed in front of the concrete structure as a self-supporting façade. The concrete structure carries all loads except the facade.

Type 2: The structure is made of wooden ceilings and stiffening wooden walls. The zoë modules form the facade. The modules take over part of the ceiling loads.

There are other configurations possible depending on the fire protection regulations, the selected ceiling type etc.

Design options
The façade can be designed with a lime plaster or a mineral system plaster > STEICOsecure. Instead of the plaster façade, a ventilated façade with a large number of possible facade claddings (wooden slats, wooden panels, fiber cement panels, etc.) can also be realized. The wood soft fiber board is then supplemented by a vapor-permeable wind paper.

As soon as the wooden construction has settled the modules are provided with a 5 cm thick earthen coarse plaster. This is then coated with a colored clay fine plaster – either only in the area of the basic plaster (the wood structure remains visible then) or on the entire wall surface, the wooden surfaces first being covered with a plaster base. > Design with clay plaster

Integration of building technology
The earth coarse plaster can also be used as installation level for electrical lines, sockets and light switches or low-temperature heating or cooling registers. These can either be inserted in the prefabrication or on the construction site. > solar

Open construction system
zoë as a modern timber construction element can be combined with the usual solutions for ceilings, interior walls, windows and building technology.
