Adaptive facade collectors for solar architecture

The ArKol research project is developing novel thermal solar collectors for use in building facades. Borderstep supports the project consortium on behalf of Fraunhofer ISE with selected methods of innovation and technology management.

The first results of the project are two novel concepts for facade collectors based on heat pipes: a strip collector and a solar thermal blind. These give architects plenty of freedom to design solar architecture. The heatpipes allow efficient heat transport on small cross-sectional surfaces.

While the strip collector can be integrated into the façade and offers high efficiency, the solar thermal blind is to be installed between glass panes (e.g. in glass façades or windows). The requirements for solar thermal blinds are particularly high. It is movable, generates renewable heat and at the same time reduces the amount of energy that reaches a building in the form of solar radiation through glass surfaces.

Developing marketable products based on the new concepts for facade collectors is a challenge. This applies in particular to business models and value-added partnerships that are tailored to these concepts.

The project aims to systematically record and analyse the requirements of participating players and future users of new products. Scenario-based business models will be developed together with the project participants. This enables the evaluation and comparison of promising application and product variants. In this work, Borderstep can draw on its experience in the development of facade-integrated solar technology.
