Grüne Erde World - Visitor Centre and Show Production

“Grüne Erde-Welt” is the name of the new constructed visitors center of the company "Grüne Erde". It invites the customers to visit production of textiles, mattresses, upholstered furniture, natural cosmetics, as well as a large store and a vegetarian organic bistro.
Like the company that stands for environmental responsibility and quality awareness, the project from the beginning had goals for sustainability: only natural resources and building materials should be used for the construction. The buildings operation should be climate-neutral. And especially for Transsolar relevant, to operate the building it should only use energy which can be gained within the own property.
Transsolar developed the energy- and environmental concept with regard to thermal comfort, fresh air quality, solar profits, shading and daylight by integral design process using dynamic simulations for the buildings ventilation and optimized daylight. 13 atriums with trees planted inside are both, an innovation for architecture and air conditioning: Sized between 20 and 30 m² they allow daylight to enter into the inner building and they are also core elements for the natural ventilation.
The energy concept developed is well balanced regarding energy needs for heating, cooling and electric energy to run exhibition, show production and special areas; the center is so a zero energy building, since it generates as much energy as it consumes. In general the building uses natural ventilation, only in times when temperatures outside are getting uncomfortable the mechanical ventilation system is being used, but then with heat recovery. The floor serves for heating and cooling, exclusively using heat or cold supplied by the geothermal system. 6000 m² of photovoltaic elements integrated into the building to provide electrical energy. The “Grüne ErdeWelt” is made of local wood and recycled concrete, the ecological solution for its insulation is sheep wool. The center is officially opened for visitors since September 2018.
