The development of a new aluminium - sun collector, where the working- fluid completely run through the absorber- area, to reach a higher efficiency.

Development of a building board consisting of a wood fibre board, coated with clay-plaster reinforced by natural plant-fibres (BioFaserLehm) for reinforcing planking of timber-constructions and also for statical not stressed inner wall surfaces.

Log-fired furnace with low energy performance, optimised to be used in passive house constructions. The desired energy output, ranging from 1 kW to a max-peak of 3 kW, is achieved by an "energy storing unit" (energy-storage material covered by an insulation layer) in combination with valves to control the energy release.

The objective of this project is to examine the ability of magnesite bonded wood wool panels as an inside thermal insulation system, especially for houses with historical facades and to acquire starting points for further development of the products and components being used. Parallel to the data which will be calculated in a theoretical FEM-model, a field trial will be carried out to prove the influence on the inside room climate. In addition the sustainability of the system will be analysed.
