The traditional Kampa brand has stood for quality house construction for more than 100 years and is known far beyond Germany. Today, the company offers a complete range of services for private, institutional and commercial clients in sustainable residential, commercial and industrial construction.
The new K8 Building Innovation Centre in Aalen, Swabia, is the exhibition and design centre where Kampa advises its clients. This also includes Viessmann heating systems, for which a showroom has been specially set up. It is also a centre for the exchange of knowledge and experience for the construction of energy-efficient single-family homes and multi-storey residential, commercial and industrial buildings. The K8's building height of 22 metres does not seem to be much at first. But according to the building regulations, the seven storeys reach just below the edge of the high-rise. The special thing about it is that it is a complete wooden construction. Even the stairwell and elevator shaft are made of this raw material.
The design of the K8 with more than 3000 m² usable floor space is based on an efficiency house 40. This means a primary energy requirement of only 40 percent of a house built according to the specifications of the Energy Saving Ordinance (EnEV).
For the additional energy supply for heating and drinking water heating, an ice reservoir with a volume of 685 m³, three Vitocal 300-G heat pumps with a total output of 119 kW, solar air absorbers and a photovoltaic system were installed.
The built-in technology makes the K8 almost self-sufficient from external energy. The heat pumps use the heat stored in the ice storage tank. The solar air absorbers extract the heat from the air passing by and also direct it to the heat pumps. These, in turn, can be operated practically free of charge with photovoltaic electricity generated in-house.
