Energieoptimierte Gebäudehüllen in Stahlleichtbauweise für den Industrie- und Gewerbebau

Energy-optimized building envelopes in steel for industrial and commercial buildings.

Envelopes for industrial buildings provide a considerable potential of energy saving on the construction sector. A large amount of roofing and walling is being produced of elements of thin steel sheeting. The need for research and development is apparent, the topics of which can be ordered to a passive and an active side. On the passive side the energy and heat losses are to be reduced. In order to improve the thermal insulation, moisture protection and air tightness performance the building physical properties of the constructions are investigated. A particular focus is on the integral consideration of the mutual dependencies of building physics. Researches on the active side deal with the options of profitable use of the solar irradiation that hit the building envelope. In this context, the integration of solar thermal and photovoltaic technology in building systems in steel is the main aspect. Against this background, the resulting interventions in the existing structures again are the subject to further investigations. Finally, an evaluation of the achieved quality of the building envelope is carried out with respect to sustainability criteria.
