Ground water heat pump
The supply and function of the heating, ventilation and air conditioning is backed up by four heat pumps and two groundwater pumps with heat exchanger, which are fed by ground water which runs 8-13 m beneath the surface. For working the pump we source green electricity from hydro electric power plants.
Concrete Core Activation
There are 5,500 m of plastic tubes laid out in the concrete pavement. The water, which flows through the tubes covers the basic need for heating our offices in winter and cooling them in summer.
Controlled Ventilation System
The rest of the ventilation concept is based on a controlled ventilation system. The fresh air is warmed up by the heat pump before entering the room. Via an installed heat recoery system the exhausted air is recycled.
Our winter garden works as a heat buffer. The gained surplus heat is used for heating the 30,000 m³ warehouse in winter and between seasons.
The greening of our office roof is an additional measure to keep offices below cool in summer. Apart from this the flora offers a valuable improvement to the microclimate.
Wooden structure of the factory roof
The special construction of our factory roofs are a combination of the top and the bottom of wood with a stone wool layer in between. Pictures of a thermal imaging camera show almost low-energy standard – a real rarity in industrial construction.
Our voltaic system covers a surface area of 200 m² as an extension of the winter garden with a grid supply of more than 16,000 kWh per year. In addition we've got a further system on the almost 10,000 m² factory roofs. Through the usage of green electricity we generate more energy free from CO2 as it is actually consumed.
Usage of rain water
Storm tanks provide water for our ecologically landscaped garden and pond.
Through the building’s south east wall surface of almost 1,000 m² pleasantly orange light falls in the factory hall and thus minimizes the usage of artificial light enormously. This specially designed wall element reflects steeply incoming sunbeams in summer. In turn, lowly incoming sunbeams in winter are let in and heat the hall.
