(Jena, Germany) Climate protection and the reduction of carbon dioxide emissions have been on top of global development agendas.

Accordingly, research and development projects have been conducted on national and international levels, which aim for the improvement of the CO2-footprint in diverse processes.

Apart from particularly energy-intensive sectors of the industry, the building sector in particular is among the biggest CO2-emmitters: from residential homes, manufacturing facilities and storage depots to big commercial buildings, about 40 percent of the energy consumption within the EU are due to the heating, cooling, air conditioning and lighting of buildings.

Considering next-generation smart windows and façade devices, one aspect of this problem is addressed in the research project Large-Area Fluidic Windows (LaWin) which has been coordinated at the Friedrich Schiller University Jena, Germany, since 2015.

A new type of such smart windows was now presented in the upcoming issue of Advanced Sustainable Systems.

In their paper 'Large-Area Smart Window with Tunable Shading and Solar-Thermal Harvesting Ability Based on Remote Switching of a Magneto-Active Liquid' the Jena materials researchers introduce prototypes of a window that changes its light permeability at the touch of a button, and, at the same time, can be used for solar-thermal energy harvesting (DOI: 10.1002/adsu.201700140).
