Development of technique and components for the production of back ventilation-free thermal flat collectors.
Identification of the potential for solar thermal systems for multi-family houses and identification of solutions to overcome performance difficulties.
Study of the applicability of air to earth underground heat exchangers for pre-cooling of the air-conditioning air for buildings and compilation of a simulation program and a planning handbook.
Monitoring studies of passive houses in more than 200 apartments in five European countries.
Study of the impact of the collector hydraulic, piping and arrangement of fittings on stagnation behaviour on solar thermal systems.
Development of large solar thermal systems that activates metal sheets, which are mounted in façades or on roofs and the realisation of pilot projects.
Compilation and comparison of solar heated domestic hot water and space heating systems in nine IEA-member countries.
Development of a new-long term storage tank (thermo chemical heat) for solar space heating. Storage medium: silica gel.
A transparent insulation material, based on renewable raw materials, has shown to be excellent for the gaining of solar energy and has shown an unproblematic behaviour regarding moisture.
